[See the full post at: The second August patch for Win10 1903 shoots one core up to 100% utilization]Didn’t Microsoft state that there are NO known issues with KB 4512941 ?

Didn’t this patch sit like over a week at release preview ring? So much use for that.
Might have probably just send it straight to public with the 1809, 1803 and 1709 patches. Then MS could have had time to get this fixed in third patch round by the end of this month. Now it’s likely to be fixed late next month as regular patch Tuesday is less than 10 days ahead, no way MS is going to bother hurry to fix for this by then.

The following Registry Change help to fix the problem for me:
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Search] „AllowCortana“=dword:00000001 „BingSearchEnabled“=dword:00000001
After change boot the PC.

Whats the deal with the Home users who must take all the updates? I don’t hear any complaints from them. I still use W7 home premium. Should we home users be in a hurry to switch to W10?
Windows 10 home users who take the auto updates lose each month $1T in damages due to non functioning PCs.
No one will take Microsoft to court over these damages.1 user thanked author for this post.

That is significantly higher than the average global net income for Windows 10 Home users.

“Check for Updates” in Win10 does not mean CHECK for updates.
It means “Download and install whatever is available whether you want it or not.”
“Check for updates” in Win10 makes you a “Seeker.”NEVER click “Check for updates” in Win10 unless you want a surprise.
-
-
No, I didn’t miss the point.
The “Download and install now” is a completely different thing from “Check for Updates.” They are two un-associated ways of handling updates.“Download and install now” is a suggestion. “This is available, do you want to download and install?” It does not download/install unless you agree. The option may not always be available.
You checked for updates, but “Check for Updates” has always not given the option. It is not a “check.” If the update is available for your PC (which it was after you uninstalled it), if you click on “Check for Updates” you get the immediate download/install, without it stopping to say “This is available, do you want to download and install now?”
-
if you really want to manually check for updates in Win10, use either WUMT (windows update minitool) or WuMgr from DavidXanatos github page
those 2 tools can check for new Win10 updates w/out automatically downloading & installing them

Microsoft may have already pulled KB 4512941. I went to block it on my one 1903 PC using wushowhide, but it’s not showing up there. It’s not showing up in my Update History either, so it hasn’t already been applied (nothing since August 3). I don’t have Cortana enabled, but it’s a cumulative update; it should still show up on wushowhide if still available.

KB4512941 is still listed in the MS Catalog for download.
I was too late , didnt notice the thread…. Now I have renamed the Cortana-search in it’s directory , so my processor is quiet again. Did not use Cortana anyway.
Reminds me of those early days I had to quiet dr.Watson…… Told my boss that wasnt the way to shutup lousy programming ….
Who can tell how that ended?

That bold statement is not true for any of my machines. Call me a Seeker; I click on All settings > Update & Security > Check for updates regularly. Maybe not every day, but close enough.
I got KB4512941 and KB 4511555 on my daily-driver desktop on 8/30 (the first time it was offered to me) only after clicking on “This is available, do you want to download and install now?” I got them both on my NAS and my laptop today, same circumstances; clicked on “download and install now”.
It’s been that way ever since that feature (download and install now) was incorporated into Windows 10 Pro, which is what I’m running on both sides of my dual boot on my daily-driver, my NAS and laptop.
I don’t have any of the 4 cores of my CPU red-lining or running at 100% at any time I’ve checked using Task Manager/Performance and Resource Monitor. I have Cortana and a few other services “suspended” through options available in the GUI. There was no need to go into the registry to do so. In Resource Monitor they show up as “suspended” and using 0 resources.
I don’t delay updates, I run fully patched, including quality updates, all the time on every machine on my network; daily-driver first, then the others as I get time. I have no BSOD’s, no blank screens, no problems. The canary is still singing.

Wow, I uninstalled KB4512941 after having some issues (no search, Start Menu lost all customizations) and deciding to wait until they’re fixed to try it again. Since it wasn’t a “required” patch I didn’t think anything of it. Walked away from the computer for an hour or so, came back, and Windows 10 helpfully re-installed it for me without my permission or acknowledgement!
Thanks, Microsoft, that’s exactly what I wanted it to do when I uninstalled it manually.

Once more, for the record, I’m not an IT professional riding herd on a network for a business that uses mission-critical software. I’m just a home user with a home network who likes to do things my own way. My web site (no ads) has more details. I’m well aware that the IT Pros that frequent AskWoody have greater concerns.
I had everything but the B side of my dual boot up-to-date, so I booted over there. This is how it works when I’m fully updated, nothing (except drivers) blocked or skipped.
Also, I’ve never gotten a spontaneous restart because of an update. I always get this:
I don’t skip updates (except drivers), I don’t wait to update, I don’t worry about MS-DEFCON. I stay fully updated on 5 Windows 10 Pro installations. All my platform hardware is 6 years old (my SSD’s and HDD’s are newer) so I’m far from the bleeding edge. But everything just works, the way I want it to work, that’s all I’m after, and the canary is still singing.

Woody welcomes differing points of view, differences in experience and opinion. Being a member or reader here is not restricted to techie/geeky types and does not require adherence to the DEFCON System.
The MVPs are recognized for their expertise and their ability to give helpful constructive advice. That does not confine them to any particular viewpoint. Many came over from WSL, but there are others of us that are just AskWoody squatters. Some love Win10, others do not, and some are even willing to help Win7 Users beyond EOL.
But one thing you can count on. The MVPs are here if you have a question or need help.

Just for clarification on my point (That Win 10 reinstalled and rebooted on its own) I’m running Windows 10 Enterprise (I am in IT) and do usually try to update fairly fast just to be aware of issues. Thankfully I usually avoid them. In this case for the initial installation I did the “Check for Updates” and then “Download and install now” for KB4512941. It installed fine and seemed to run fine for a day or so until the weird issues started, so I uninstalled it through control panel. I rebooted the computer, verified things worked as expected, and left it alone to do other things. (I did lock it)
I came back and some of the windows I had left open were in weird places, and some were gone. The start menu/search wasn’t working and when I went to Update History, it showed that KB4512941 had been installed today and the machine had done a restart in the time I was gone.
This doesn’t seem like the normal “Expected” behavior in any way. I did not click “Check for Updates” at any point after uninstalling KB4512941 because I did not want to wake the (I presumed) sleeping giant.

These sorts of posts make me curious. If that’s your stance, then why become an MVP here? The main premise of the site is “don’t apply updates right away. Wait and mitigate the risk.” So what draws you to the site if you don’t do that?
I came over from Windows Secrets Lounge. There, I was a “Super Moderator”, equivalent to MVP here. To answer your question, in part, think of me as the canary in the coal mine. My systems are fully prepared for catastrophic failure. The first part of my signature line is
Create a fresh drive image before making system changes, in case you need to start over!
I use Task Scheduler to create drive images weekly. I use Task Scheduler to copy my data in three different places, in addition to OneDrive in the cloud. I use a drive dock in the top of my NAS to copy my drive images to a removable HDD. I’m protected “three ways from Sunday” in the event that some Windows Update might pooch one of my systems, so I’m not in the least worried in being a “Seeker” and getting updates as soon as they are released. I can undo any damage in under 6 minutes just by restoring a drive image.
But in my experience, that hasn’t happened; no Windows Update has given me BSOD’s or black screens or bricked any of my PC’s. I’m not advising that everyone should do as I do, with the exception of keeping fresh drive images; I advise everyone to do that.
Over the years I have helped a number of people with a number of problems, and I’m here at AskWoody to continue to do just that. Not all problems are the result of Windows Updates. Some require digging into the guts of Windows and sorting some things out. Those are the kinds of puzzles I can really get into, and I like to help folks.

Out of morbid curiosity, I installed this patch on my Windows 10 Enterprise 1903 machine. I have Bing and Cortana disabled through Group Policy (not by directly editing the registry). I got the problem described here: black search window and 1 CPU core at 100% usage. Rolling the patch back now. Hopefully they get this fixed soon.
Edit: Removing KB4512941 brought things back to normal. KB4512508 seems to be working fine on this PC, though.

Enabling Bing will fix that as well.

Uninstalled and rebooted. CPU now close to 0%. But in Updates > View Update History, KB 4512941 is shown as still installed. Is that typical?
History is history. If an event happened, you can’t take it back. The uninstall is not recorded in Windows Update History because Windows Update did not uninstall it, you did. History is not the same as installed updates.
If you want to see what is currently installed, Look in the link “uninstall updates” in Settings, or Control Panel\Programs and Features “View installed updates”
Also, looking at bbearren’s post above, I have never once seen “Optional Updates Available” in Win 10 Pro. Is there a setting to make that a possibility?
In Win10, updates are not identified as “Important” and “Optional” as they were in Win7/8.1. The Optional Updates (with the exception of emergency hotfixes) are the updates issued between Patch Tuesdays. Depending on your settings (Group Policy and/or Registry) you may not see the optional updates unless you deliberately “Check for updates” and thus become a “seeker.”

Yes. Under Automatic Updates\Windows Update for Business there are three items that give the settings for SAC and deferrals that used to be in the Settings app GUI under Windows Update\Advanced Settings. Read carefully what Enabling and Disabling does and what each of the settings do.
How long MS will keep them functional for non-domain connected PCs is anybody’s guess. Control is going away, unannounced, bit by bit. -
PKCano – thanks for guiding me to that spot in Group Policy.
But it is not clear to me what setting change will make possible what we see in in bbearen’s post above: “Optional updates available”. (Trying to copy that below.)
Sorry – I confess to playing hooky when you were teaching this class the first time around.

This was unannounced and specifically affects non-techie Users who do not know how to use Group Policy or the Registry.1 user thanked author for this post.

The GUI settings HAVE been removed. Show me a screenshot from 1903 with functional GUI settings.

Can you show me a screenshot showing you can in fact change the 365 day deferral (in 1903) to 360 days using the GUI settings. and I will eat my words. Because every time I tried that the settings pulldown either disappeared or became non functional (grayed out). I’m willing to concede if you can show me.
-

Can you clarify something. The OP asking the question was about an individual machine, not a business situation. I am running Win10 Pro 1903. This is what I see. The GUI setting is grayed out (nonfunctional) with Windows Update for Business set at SAC and 365. The question: Are you running the Pro or Enterprise version? And, if Pro, what settings are you using?

Bear in mind,
I don’t skip updates (except drivers), I don’t wait to update, I don’t worry about MS-DEFCON. I stay fully updated on 5 Windows 10 Pro installations. All my platform hardware is 6 years old (my SSD’s and HDD’s are newer) so I’m far from the bleeding edge. But everything just works, the way I want it to work, that’s all I’m after, and the canary is still singing.
As far as settings via Windows Update Advanced options, this is what I’ve selected:
As far as editing Local Group Policy, this is it:
I check for updates frequently; label me “Seeker”. With the caveat that I’ve disabled driver updates, I’ve not turned down or uninstalled any Windows 10 Update that has been offered to any of my PC’s.
Does staying fully updated keep me from having problems with updates? I can’t say, because I have no way of testing that hypothesis. But I can say that I haven’t had any problems with any Windows update on any of my 5 Windows 10 Pro installations.
And again, I’m not an IT Pro riding herd on a large network of machines running mission-critical software, I’m just a home user with a home network, set up the way I want it to run.

Microsoft has re-released KB4512941. It just installed a couple of minutes ago via Windows Update, after I clicked Check for updates. No noticeable change for me, but then I wasn’t having any red-lining with the first one.

That’s weird. There’s no new entry in the Catalog. I just downloaded it from the Catalog, and all component files have 8-28 modification dates.
