Thanks for the info, Susan.
So if we haven’t installed any of the March updates, when the DefCon rating is raised and it’s time to install the April update KB4093118, should we also install KB4099950 assuming that it is offered again? It was optional but then disappeared.
Also, what about KB4100480 which I didn’t install in March but it’s still offered now as important and checked, should that be installed when the April updates are recommended for installation?
Finally, if either KB4099950 and/or KB4100480 are recommended in due course in addition to the April monthly update KB4093118, will there be any recommended order or can they be installed in one lot?
I realise it may be too soon to know the answers to these points, but I’d be grateful if they were addressed please when the DefCon rating is raised.
I’m running two unconnected Windows 7 x64 desktops at home. The only updates I installed in March were the MSRT and the four checked Office 2010 updates (but not the unchecked ones KB2965234 and KB4018317).

I just posted in another thread that today I turned on a server 2008r2 system running on a vmware server that had not been running since October 2017. I ran windows update connected to our WSUS and 14 available updates were available including the new kb4099950. No issues of any type to report including the previous nic issue.

I think E1000 is not affected as it does not emulate PCI Express, but traditional PCI.
I haven’t tested, but this issue introduced in the 2018-03 Monthly Rollup is identical with the one fixed in the past by the private hotfix KB2550978 (included in KB3125574).
See this VMware article for details and various NIC emulated cards. Workaround 3 provides a way around the issues without installing the patch.
https://kb.vmware.com/s/article/1020078EDIT: A lot of the users affected have Wi-Fi cards which are generally PCI Express cards.
A large number of users are likely not to have any side effects because they use the PCI built-in network cards, especially on older computers.4 users thanked author for this post.

I have 3 Win 7 computers, all group B. On each, I installed the pre April 17 version of 4099950 from Windows Update, followed by 4088878 from the Update Catalog. No issues of any kind, neither with IP addresses, network connections nor anything else. All 3 machines showed the presence of an updated PCI.sys file in the Windows\system32\drivers folder. None of the machines had PCIClearStaleCache.txt in the Windows\Logs folder.
Last night on one of the machines I downloaded the post-April 17 version of 4099950. It contained two files: the stand alone package which is apparently identical to the pre April 17 4099950, and an additional file, the PCIClearStaleCache.exe file. I ran the latter as an administrator. No issues and the only difference is that the PCIClearStaleCache.txt file showed up in the Windows\Logs folder. But this .txt file simply told me what I already knew, namely that the updated version of PCI.sys file was in the Windows\system32\drivers folder.
So, it appears as though the additional .exe file in the post April 17 4099950 does NOTHING other than tell me something I already knew and that had already been done by the pre April 17 4099950.
I’m not sure how to interpret this, but some possibilities are
1) on this machine I wouldn’t have had any IP or networking issues anyway upon installing 4088878
2) There really is no need to prefer either version of 4099950 over the other
3) the group B 4088878 doesn’t cause the IP or networking issues.My main interest, though, is whether or not having run the .exe file in the post April 17 version, I’m protected at least up through the March updates. I’m holding off on the April 4093108 update for now.
As always, I’d appreciate any input from those more knowledgeable than I (that probably is most of you. 🙂 )

Patch Lady,
I am strongly interested in what might be going on with KB4093108, the Security Only patch, rather on its sibling, the unfortunate Rollup. Same problem with that other one? Or not enough information yet?
Woody wrote that he does not know about the Security Only, but that “the problem is quite widespread.”
So here I am now, busily chewing off my fingernails to the quick, hoping for some clarity.

Well, I’m afraid W7 is a lost cause… MS again and again proves they are unable to patch that OS in a reasonable way, release junk after junk after junk. Switching to W8.1 (which will be receiving patches until 2023) for sure sounds like a much better alternative while you are still able to keep patching under your control, instead of having it crammed down your throat by Microsoft without any other option and getting upgraded twice a year with a new buggy W10 fallen creators late spring updates…
By 2023, either MS will have put their derailed train back on rails, or people will have abandoned their OS altogether.

So Microsoft is telling me I need to install this update (KB4099950), released on April 17, 2018, BEFORE I install either of two updates (KB4088875 or KB4088878) that were released on March 13, 2018.
Where the %#$@Q% do I get a time machine to make this happen????
If I’ve read this correctly, this is a new high (low?) in update screw ups.

My question to Microsoft is what are the average pc user suppose to do when they have no knowledge of any of this. How would the average person even know to install one update before another, or uninstall an update then reinstall the same update from the catalog. Does the average user know what the catalog is or how to find it?
-
The average user probably does not know how to evaluate when and how to install patches. Patches look the same and have the same weight: optional and important are treated equally. Instructions are difficult, obscure, hidden, contradictory, or result in link-not-found errors.
If patches are installed, it’s because the user mashes computer-anything-that-moves and forges onward with metaphorical sledge hammer hoping for the best.

You have just asked the big question. The people you are talking about are not just the ones with Win7 Home who do nothing but email, search the Internet and have their PCs on Auto Update. They include many small (and not os small) businesses who do not run (cannot afford) Enterprise Editions or full-time IT staffs.
Microsoft is obligated to support Win7 until 2020 for what amounts to half it’s user base. It’s not fulfilling that obligation by turning out defective updates for the public to Beta test. And it’s not doing much better by it’s Enterprise customers because it is feeding the same broken patches to WSUS and SCCM.
Some entity/agency needs to put it’s foot down and hold Microsoft to it’s obligation.
-
As you most aptly state, more than half of Microsoft’s enterprise clients are still on Windows 7. Is this the way to treat your most valued clients?
Today, the IT department shoulders the burden of maintenance and the users in an enterprise are primarily oblivious to it. These users are no more computer literate than the average home user. A locked-in AND locked-down environment makes Microsoft look good. The locked-in side will soon disappear with the maturing of cloud services. Microsoft’s monopoly is set to dissolve.
I do not think that the obligations set out in ‘extended support’ has anything to do with the issues that have plagued Windows 7 since January 2018. This is basically sloppy, rushed work by a small group of people. I think there is a good amount of indifference from Microsoft management as well. It will cost them.

Susan,
The big question that I originally posted here and which Woody quoted in his Computerworld article is:
So those of us who installed KB4099950 before March Rollup KB4088875, but prior to April 17, 2018, have to uninstall the older version of KB4099950 and reinstall to be sure we have the most recent version?
Are we supposed to do that before or after installing April Rollup KB4093118?
Do you have the answer to this question?
The last monthly update I installed was February’s Rollup KB4074598 on 03/06 after DEFCON 3 was issued. Per instructions I installed KB4100480 on 04/01 and KB4099950 on 04/07 in preparation for KB4093118. I did not install KB4093118 because of its issues.
Now it seems I need to uninstall KB4099950 and re-install it.
Can someone please advise. Do I uninstall KB4099950 and reboot? Then do I run Windows Update and will it find KB4099950 again? Or (I have downloaded the two files from the Catalog) do I run both windows6.1-kb4099950-x64_245d5aaf7d50587297825f9176be166c47ad10f7.msu and pciclearstalecache_1c944f48bfb21d88a2054683abcd02327ecf6b37.exe and reboot? Or do I do nothing and leave the KB4099950 that I already have installed alone?
This is so confusing and I want to do it right. I used to be in fear of Jan 2020 but that fear is no more because for me Jan 2020 has already passed and patching has become an unbelievable nightmare (at least for me) that I am somewhat comfortable with not patching since that will be the reality come Jan 2020 anyway. I am more afraid of my machines becoming unusable than I am of being backleveled on maintenance.
I read this site daily for instructions but now I do not know what to do for KB4099950.

HOOEY!
It is almost May. Miraculously, I was able to install the March security only patches (with more complementary BSOD’s) and moved on to the April security only patches. Question, why would a person need to (re) mess with KB4099950, anyway? I currently have PCI.sys v6.1.7601.24056 on all the Win7 machines. The PCI sections in the registry(s) have no “SlotPersistentInfo” present in the Device Parameters entries. Interestingly, the machines that have wifi NIC cards generated the .txt file in the logs, whereas the machines that connect using usb wifi NICs have no such “.txt” logs, and besides they are listed in the USB section of the registry not in the PCI section. Personally, I am weary of all the circus hoops required to attempt to stay current with these defective and unacceptable “security” updates. PKCano and others are right to restate the fact that most casual Windows users are just that. So, I would very much appreciate a power user to recommend a “final solution,” to this mess tagged KB4099950.
As always, thanks to Woody and company for working so hard to make sense of the long running update nightmare…
1 user thanked author for this post.
Have same question as others. Did not install March rollup. Did not install 4099950. Am going to install April rollup. The full one I always do, not the security only.
Do I have to first separately install KB4099950 or is the rollup all I need?
2 users thanked author for this post.
It seems KB4099950 of either old revision or a new one is intended/applicable only to installation of KB4088875 or KB4088878
The indirect confirmation of this idea is a current m$ WSUS approach as below:
If no KB4099950 installed then both KB4088875 & KB4088878 aren’t offered.
If KB4099950 installed then both KB4088875 & KB4088878 immediately listed.
Thus if you don’t plan to install either of these 2 March 2018 rollup and/or preview massive updates then you also don’t need to install this registry patch KB4099950 or can safely remove it if already installed.

Is there any action which a user can take which will show ALL of the hidden updates instead of just the last FOUR?
Walker, I ran into a similar issue when I once checked my hidden updates and saw that I had none, even though I knew I had many.
Try this: run ‘Windows Update’ first; once there, ‘Check for Updates.’ Then, ‘Restore Hidden Updates.’ One needs to ‘check for updates’ at least once before being able to restore hidden updates. Hope this works for you.

@SueW: Thank you for the recommendation, however I was already aware of this “glitch” in not getting many (except recent ones) updates which had been hidden. I was only able to get 4 of them twice now, however I may try again.
I’ve seen it where you couldn’t see “ANY” of these hidden ones, however it’s been quite a while, and after I began checking updates first everything came up, however “not now”, so I’m wondering if MS has added “something” which has this function “NON-FUNCTIONAL”. I’m Win7, x64, Home Premium, Group A. Never had this problem until just recently. Thank you for the information you provided. If I’m ever successful in attaining the old COMPLETE list of hidden updates, I’ll post it here. 🙂

well, sorry, I never saw such absolutely odd stuff like limit of 4 updates in any of win7 WSUS lists including the hidden ones. Moreover I guess it’s just impossible to set such limit or your win7 update center is damaged.
Anyhow 1st pls check your win7 wsus setting like a pic below. Pls don’t care of a note on ‘some parameters control by admin’. It’s my particular case.
2nd – the another pic below is just taken from my win7sp1x64ultimate of its current updating status as Dec2017 rollup but KB4099950 PCI 29KB registry patch is installed!

I am in awe of the knowledge on this blog. And I am learning from you. However, as just an average Group A computer user, I’m hoping that when all the dust settles we will receive a simple instruction on how to proceed. This should include whether we need to install 4099950 separately or just the April Rollup. Again, thanks to all who devote so much time and effort to help us keep safe on our computers.

I, like you, would consider myself pretty much as an “average Group A user”…with the distinction of one who wants to learn, understand and in some measure take control over my computer enough to insure I am running a safe, stable and secure environment. Last month seems to have been one of the more complex and confusing for windows-7 in quite some time, and while the more we read and consume the mounds of information, the more confusing and anxiety ridden the experience may seem…it is important to keep up so as not to miss some subtle answer that may slip through if we are not paying attention…it is none-the-less- reassuring than ultimately just prior to the next round of updates Woody always manages to pull things together enough to give us a write-up in his ComputerWorld site to explain the procedure(s) we need to follow to hopefully insure success…in a straightforward and concise manner. So while we may stress in our desire to follow and understand throughout the month just what is going on and what we need to know…things seem to flush themselves out just in time…even if we may always be a month behind. Hang in there…Woody’s has not failed me yet. I hope you find a bit of comfort in these words!!!A ship in harbor is safe, but that is not what ships are built for. --John Augustus Shedd

anonymous #186251….I did state that March’s were the most complex and confusing month’s situation I have thus far experienced, however I did manage to tread through the wilderness and break through the other side successfully, minus the KB4099950 issue which still remains unsettled on my machine though with no apparent backlash that I can see…but I managed to scale through with the help of everyone here in regard to all the other updates and KB’s…so I consider that to be in large measure a testimony to the value of following the advice here…questions did still remain, but I am still on a functioning machine thanks to all here. I consider that as close to success as I could hope for, given the nature of the issues Microsoft has thrown at us. I respect your opinion…but I will still give Woody and All a thumbs up…for, after all, we are each responsible for seeking our own answers and making our own decisions in regard to our own unique devices and experiences…Woody is not responsible for what Microsoft does…nor for the maintenance of our machines, thus I will accept graciously any guidance I might glean from this site…now and going forward.

Agree not so much for March, certainly no definitive direction on what to do. Some of us updated, others awaiting more clear direction for April. Some even rolled back to December 2017. What a mess! Woody and Susan not even in agreement!
As the saying goes, “everything should be made as simple as possible, but no simpler”…
in other words, dude, there’s not always a simple one-size-fits-all “right answer” universally applicable to everyone in every situation.That being said, thanks much to woody & susan & abbodi86 & mrbrian & ch100 & pkcano & the many others here on AskWoody providing constructive–and much appreciated–information and insight and advice. Because of your input I’m better informed on patching matters–and therefore in a better position to make patching decisions for the systems I’m responsible for.

The Defcon system works great. I’m never intimidated by making my own choice when there is enough information. I am frustrated by Microsoft’s poor documentation and testing. I really appreciate the good information that I find here… and especially that there are people willing and able to test the patches that Microsoft puts out there. The poor people not following the Defcon system were the beta testers… and they found lots of problems for us since the beginning of this year. The actual testing done by various Loungers and MVPs then pinpoints what the problems are, along with possible fixes. There was a lot of information posted about “I did this… and this is what happened”… That is not the same as “you should do this, now”… but will be part of what Woody considers when making his patching recommendations.
I really appreciate that Woody respects that there are those of us who want to follow different patching strategies. I didn’t even know that the possibility of foiling telemetry and auto-updating pitfalls even existed before I came here. But, I have had to figure out what my values are (and they are about not allowing privacy invading technology loose… and I’m not telling anyone else they have to have the same values), and educating myself as to how to do that for my laptop.
Yet… it can be frustrating for people who jump in here, in the middle of the patching fiasco that Microsoft has presented us this year…
To me, I have very clear ideas about what I want my laptop to do and not do… that probably makes it easier for me to make a choice, when presented with such. I accept that there are risks, no matter what direction I take. The value, here, is that I have a pretty good idea of what those risks are, and how to recover from them. That is what I’ve learned, in addition to using the Defcon system, to keep my system safe.
What does having a clear path of safety mean to you? Woody recommends Group A patching for most people. From what I hear (Group B, here, so not tested first hand) most of the problems of the last three months are being worked out. There was a lot of testing and retesting, and checking and double checking, changes by Microsoft, and more testing and checking… and that gets reported. There have been a lot of problems, but there haven’t been a lot of complaints from those on Group A, following the Defcon system. That means that they have updated through March… successfully… following Woody’s instructions… and are waiting for April patches to be cleared…
And yes, Woody (and Susan) gave us the heads up on the problem (Total Meltdown) that Microsoft had opened up, that was worse than the problem being patched… and they gave us choices about what to do about it… but, if you read through, they informed us about what the problems were, what the risks were, and what our choices were. Somehow, I feel much better about that, than turning on automatic updating, and taking my chances that Microsoft knows best… I have too many family members who had GWX regret… whereas, by following the Defcon system here, I avoided GWX, and all the patching pitfalls, and have a stable and useful computer, that has had none of the bugs being reported here. It is vulnerable to things that would have been problematic on auto update, but Woody’s Defcon recommendations have always guided me through…
I’m curious, what about the Defcon system isn’t working for you? It may be simply a matter of deciding which Group you are in, and double checking those particular instructions and apply them to your system. We can’t fix Microsoft, but we can avoid the worst that they are throwing our way.

Please follow this link: https://www.computerworld.com/article/3268133/microsoft-windows/get-the-march-patches-for-your-windows-machines-installed-but-watch-out-for-win7.html
And realise that it was written on 6APR2018. You seem to want one authoritative direction out of the many learned examples, opinions, and advice that is available from a large group of people. On this Website, AskWoody dot com, that would be Woody Leonhard. He alone commands the MSDefcon rating that you have stated you would like to follow. That link is to the most recent occasion that Woody raised the MSDefcon level, temporarily, to allow for March released updates to be installed. It may read as dated, because two weeks has allowed for new developments to occur. And this fluid situation creates new advice that adds to your confusion.
That series of Computerworld articles gives direction straight from Woody’s fingertips. Outside of his control is the poor environment that Microsoft has created in its own updating structure this year. So instead of his usual ‘do it this way’ direction, Woody was forced to acknowledge that Win7 had difficulties, and gave optional advice as well. But Win10 directions were so clear you may have skipped right over them.
Windows 10
Go ahead and install all outstanding Win10 patches. They were re-released and re-re-released in March, and the current versions appear to be working OK. Heaven only knows what’s going to happen on April Patch Tuesday, so get the patches squared away now.
(from the Computerworld article linked above)
Under the MSDefcon system, there will be no further directions until the level has again moved to a level 3 or more. All other advice is outside the MSDefcon system.
It is also possible to read and share opinions outside the MSDefcon system of patching. But that is not definitive advice you seem to seek. I, like many, enjoy reading more information, even if I do not intend to take any action until after Woody has written his next MSDefcon article for Computerworld. It will publish the same day that he changes the number at the top of this and every AskWoody page when he creates a teaser topic on this blog that will link to that next Computerworld article.

Don’t know if this helps anybody, but since this site has been such a great help I figured I’d post my current standing. I have a Win7 x64 system that I had all patched up for Jan/Feb. With the March mess I skipped the March rollup. I did install the original KB4099950 from WU and never got the txt log file. Yesterday I decided to bite the bullet and did the following:
1) Hid the May preview rollup in WU
2) Uninstalled the old KB4099950 and downloaded the new version from the catalog. After installing I now had the txt log file
3) After rebooting I installed KB4093118
I’m now all patched up and been running for 2 days now with no issues that I can tell. For me at least it looks like hiding the preview rollup and pre-installing 4099950 has worked well with KB 4093118.

“Updates for other Microsoft Programs” will give you updates for programs like Office, C++, Silverlight, Skype – updates for OTHER programs, NOT Windows updates.
You may not be seeing past updates because they are not needed. The Rollups and Previews are CUMULATIVE. That means they contain the parts of the previous updates.For example, lets start with Jan:
Jan 2nd Tues – Jan Rollup contains (Security, non-security, and IE11 parts).
Jan 3rd Tues – Jan Preview contains (Jan Rollup + Feb non-security)
Feb 2nd Tues – Feb Rollup contains Feb Preview (Jan Rollup + Feb non-security) + (Feb security & IE!!). Now you have all the parts of the Jan Rollup + all the parts of the Feb Rollup.SO, once you have Feb Rollup, you nolonger need Jan Rollup b/c it’s contained in it already. You will no longer see Jan Rollup in Windows Update because you don’t need it anymore. You have all the parts of it in the Feb Rollup.
Now, that works most of the time – except when MS messes up. But if you can see the latest Update, in this case the April Rollup, you are not missing anything because it contains Jan, Feb, and Mar as well.

I am Group A (Win7 X64). After reading about the March debacle, I had installed KB 4099950 on 10 April, by I missed the March security roll-up. So, my question is: do I need to uninstall the 10 April KB 4099950 and install KB 4099950 of 17/04, or is it all overtaken by the April security roll-up, which I would install when we get to DEFCON 3.
Appreciate any advice on this.

I would find it interesting to know why, when Microsoft state that KB4099950 should be installed before KB4088878, it would now be alright effectively to install KB4099950 after KB4088878? If the answer is too complex, I’ll just take your word for it.
Suggest you take his (her?) word for it. But, fwiw, short version prbly would go something like this:
KB4099950 was released to address particular issue.
Although initial KB4099950 didn’t install correctly, you got lucky when you installed KB4088878 and didn’t happen to be affected by issue KB4099950 was put out to address.
The purpose of now uninstalling and reinstalling KB4099950 is to ensure underlying issue KB4099950 was released to address is actually fixed on your system.
You don’t have to worry about patch order now because (1) you got lucky earlier and KB4088878 installed earlier without issue, and (2) when you now (re)install KB4099950, system is smart enough to know _not_ to overwrite newer stuff (i.e., system files with new updates/fixes) with older stuff (i.e., system files without newer updates/fixes).
Hope this helps.

will the included KB4099950 in KB4093118 (April CU – Group A) supercede the original KB4099950 or does the original need to be uninstalled first???
Suggest you uninstall original incorrectly-installed KB4099950.
But then, hmmmm…_Specific question for abbodi86 (or Susan? or someone with a test system and extra time?)_:
If KarenS, or anyone else in Group A (I’ve seen several folks asking variations on similar theme), uninstalls original incorrectly-installed KB4099950, and then–-when Woody advises-–updates her system per his instructions using the latest/updated version of Win7 monthly rollup KB4093118 via windows update … will the KB4099950 fix then be properly installed?
… or _must_ she (and other Group A folks in her situation), _after_ uninstalling original incorrectly-installed KB4099950, install KB4099950 fix _manually_ (i.e., because of initial blown KB4099950 install), using either _catalog download (https://www.catalog.update.microsoft.com/Search.aspx?q=KB4099950)_ or _your vbs script (https://www.askwoody.com/forums/topic/tests-of-kb4099950/#post-185592)_?

The only way for KB4099950 or KB4093118 to fix the SlotPersistentInfo issue is that pci.sys version must be under 6.1.7061.21744
so for summerize:
– if March/April Rollups installed, the user is not experiencing the NIC/Static IP issues, running the vbs script would be enough, just to be sure– if March/April Rollups installed, the user is experiencing the NIC/Static IP issues, he has two options:
1) unistall updates, reinstall KB4093118 (or KB4099950)
2) run the vbs script, hoepfully it would fix it– if none of March/April Rollups are installed, then installing KB4093118 will be enough

Maybe you should explain here for everyone to understand that if the pci.sys version is later than 6.1.7601.21744, then the SlotPersistentInfo value is ignored by pci.sys and thus not modified by KB4099950. This is intended behaviour and not a bug.
If the NIC is uninstalled and later reinstalled, the SlotPersistentInfo is recreated, but ignored by later versions of pci.sys.
KB4099950 is only a temporary hack to get over an unintended side-effect of removing undesired functionality for PCI Express cards until a later version of pci.sys is installed on the system. This was done first in a private hotfix in 2011 and most of those in the virtualisation world are or should be familiar with KB2550978 or later in May 2016 with KB3125574. That undesired functionality is not a Microsoft bug, but a strict implementation of the standard for PCI Express, which become undesired in the context.

Thank you Anonymous! That is the exact specific question I (and many others) have been trying to find the answer to but it is still unclear!
