Are you a consumer patcher or business patcher? If consumer-nothing.
If business-read the article and the links.
keep in mind these are not patches to install, rather they are manual steps that may or may not be needed depending on the type of patcher you are.
Susan Bradley Patch Lady/Prudent patcher
Business machines. I did read the articles but it’s unclear what to do? For KB5037754, section Take Action it says:
To fully mitigate the security issue for all devices, you must move to Enforced mode (described in Step 3) once your environment is fully updated.
And Step 3 says:
ENABLE: After Enforcement mode is fully enabled in your environment, the vulnerabilities described in CVE-2024-26248 and CVE-2024-29056 will be mitigated.
So… How <span style=”text-decoration: underline;”>do</span> I move to Enforce Mode?
As for KB5025885, Microsoft released an article on how to tackle this one, with a lot of but’s and if’s – enough to scare me away….
Looks like this page: https://support.microsoft.com/en-us/topic/kb5025885-how-to-manage-the-windows-boot-manager-revocations-for-secure-boot-changes-associated-with-cve-2023-24932-41a975df-beb2-40c1-99a3-b3ff139f832d

RE: “This month does include updates for Secure Boot and BitLocker that require additional steps, but for consumer machines I advise you to ignore Microsoft’s recommendations and the six (yes, six) reboots that are required to fully implement those updates. If you have a machine that does not have Secure Boot enabled, you won’t be at risk by skipping these steps.”
I was a bit confused by these comments.
I have Secure Boot enabled and Bit Locker disabled.
Are you suggesting that Secure Boot should be disabled to ensure minimum risk from the updates?
If so, would it be reasonable to disable Secure Boot prior to updating, and then re-enable it afterward?
Looking over what the additional steps are, and what they might do to all of my USB Boot Media, including Linux (until the distros and GRUB update their own Certificates), I’ll take a hard pass on those additional steps. I have enough multi-booting headaches without going out looking for trouble.

Susan, thanks for alerting us to the sneaky install of the Copilot ‘chat provider’ app. I found it installed on my Win 10 Home 22H2 PC, much to my surprise. I was able to use the ‘uninstall’ button to get rid of it.
I didn’t realize it came in with an Edge update (123.0.2420.81 or perhaps the previous one), and am surprised beta versions are installed without any warning that they are a beta version?
Edge is not my primary browser, so I have to remember to go in and update it periodically (doesn’t automatically update because I use metered connection to block updates.)
I had already followed your guidance and blocked copilot with your reg keys, and made sure the Edge settings for Copilot were off.
and am surprised beta versions are installed without any warning that they are a beta version
Windows Copilot first showed up in the beta version and then later in the regular version. So, if you don’t have Edge beta installed, you got it via the regular Edge version.
You do get a indication that you have a beta version of Edge installed, because the Edge icon looks a bit different.
I have 2 Home Win 10 PC’s. They both have Secure Boot but not Bitlocker. Neither one issued more than the one normal restart. Hmmm?
The only thing unusual was something called ms-gamingoverlay://kglcheck that appeared in my Windows/History file on one PC only. I don’t use any games so wonder why that appeared? The kglcheck exe seems also to be a hidden file I cannot access so cannot delete it if not needed.
My recent update required that I cycle through the MS (KB5036893) and Online Experience Pac to set/reset a variety of options seemingly related to AI. I refused all and was unable to continue with any Office 365 apps. I accepted the web access one and was able to continue only after closing and restarting an Office app. This seems especially arrogant of MS.
For those who do the April 9 Win 10 Pro or Home 22H2 Updates and post here, could you also include this information:
For details, see @lmacri’s post about 1. and 2. <here> and see @lmacri’s post about 3. <here>.
Windows 10 Pro 22H2 /w April updates (no problems encountered installing the updates.)
1. Do you now have the option for prompts on the lock screen? The option is supposed to be at Settings | Personalization | Lock Screen.
Yes but it looks like this and, if I click any of the + prompts, it shows no apps available to be added.
2. Do you have the UCPD installed? If so, can you use 3rd party apps without interference from the UCPD? If not, have you disabled it?
UCPD was installed (it was actually part of the March KB5035845 CU update – March CU updated files list) but I disabled it because I use SetUserFTA and it no longer worked once UCPD was installed!
FYI, the April KB5036892 CU update did “not” re-enable UCPD.
3. Do you see any signs of Windows Copilot yet?
No sign of Windows CoPilot but, like @PKCano, I’d already set all the Group Policies and registry entries to disable it back when they were first announced on AskWoody.
Windows 10 Pro 22H2 with a local home-use consumer account. I have no technical expertise but I try to apply your advice.
The Microsoft Copilot App was installed on my computer on 3/28/24.
You wrote: “As part of the upcoming resolution of this issue, the chat provider for Copilot in Windows component will be removed from devices where Microsoft Copilot is not intended to be enabled or installed.”
Should I uninstall the Microsoft Copilot App? Or should I wait for Microsoft to remove the Microsoft Copilot App? Are there any ramifications if I uninstall the Microsoft Copilot App?
NOTE: Per your advice:
I set Show suggestions occasionally in Start to Off.
I set Show me the Windows welcome experience after updates and occasionally when I sign in to highlight what’s new and suggested to Off.
Susan, this was a bit confusing:“This month does include updates for Secure Boot and BitLocker that require additional steps, but for consumer machines I advise you to ignore Microsoft’s recommendations and the six (yes, six) reboots that are required to fully implement those updates….If you have a machine that does not have Secure Boot enabled, you won’t be at risk by skipping these steps.”
I have five Windows 10 Pro 22H2 systems, though one is Windows 11 capable.
1) How does one know if Secure Boot is enabled?
2) How does one ignore MS recommendations during the update, e.g., which KBs are to be blocked and what to do during update process?
Thanks, CMA
From the Alert – Consumer Section
If you have a machine that does not have Secure Boot enabled, you won’t be at risk by skipping these steps
You just install the updates. Period.
For Win10/Pro, 22H2 with BitLocker disabled:
And you just install the updates, even if you have a machine that DOES have Secure Boot enabled?
And you just install the updates, even if you have a machine that DOES have Secure Boot enabled?
If you are a consumer patcher take no additional steps.
Image your system(s) first…before installing updates.
If something goes sideways, you can go back to where you were before.
Image your system(s) first…before installing updates.
If something goes sideways, you can go back to where you were before.
According to the KB article on the changes to Secure Boot, once you revoke the old EFI/UEFI setups for USB boot, your backups may no longer work. This is what has scared me off from doing any additional steps as a home user with stand-alone PCs and multi-booting with Linux from USB drives. I hope that when the changes become mandatory, there will be some sane and rational way to get everything updated without any loss of the ability to use backups.

Followed by:

I still need a basic clarification. Susan Bradley advised that we should just install the Secure Boot and BitLocker updates but ignore the Microsoft recommendations and the six reboots. I have never encountered this situation. What should I do to ignore the recommendations and the six reboots? Do I just allow the computer to reboot the first time to install the update and then decline the request for additional reboots? It would be very helpful to know what to expect and know what to do before installing the updates.

See Susan’s post at #2663026 for the clarification you are looking for.
In other words, as a consumer, you won’t see anything about the 6 steps.
Just in case this might be of interest to anyone here, it appears that the issue on systems with an xbox controller causing the Explorer.exe crash bug from a couple of months ago also affects the Win11 April CU. Users on reddit report that the bug was apparently fixed in the March Preview, but still happens with the regular April CU if the gameinput service is enabled and running.
Exchange Team has released a hotfix which fixes the March 2024 SU bugs as well as introduces support for ECC certificates.
Windows 10 22h2 – longest update ever for me. Sat at the updating your computer screen for 10 minutes before showing any progress. After reboot (finally) desktop icons flashed many times before settling down.
NO lockscreen widget works. I used to have weather, now NONE I select work at all. Got a fix?
And what did this cumulative do I should be aware of? Seems like it had to be significant.
Have completed updating 10 of our systems – laptops, desktops, and workstations.
All are running Windows 10 Pro 64-bit Version: 22H2 and operating as “Consumer” machines.
Prior to updating we followed Susan’s suggestion to:
All downloads and installations went smoothly except for 2024-01 Security Update for Windows 10 Version 22H2 for x64-based Systems (KB5034441) that failed to install on any of our PCs.
Update times did not exceed 30 minutes on any machine and only required one reboot.
‘Safe for Now‘ indeed!
Come May 2024 Patch Tuesday, CVE-2022-38028 will likely cause printing issues..again!
Yup, it’s in-the-wild with a CVSS score of 7.8 (HIGH)
Seems like a collateral Windows annual event../sigh
I’m running Win 10 Pro on a test/backup machine. A couple weeks ago I noticed that on an extremely long boot (10 minutes or so) a Copilot Preview icon showed up in the far right of the taskbar. Being involved with other pressing life issues at the time I didn’t think much of it and figured that as with the 99.9999% of other MS “features” that I have no use for I would just ignore it.
Tried updating the machine last night. The April .NET 3.5/4.8.1, KB5036618, installed fine up to the “pending restart” notification, but the April CU, KB5036892, gave me a download error 0x80073701. The restart took 20 minutes (!), but the Copilot Preview icon was no longer present; apparently it was removed.
I restarted again and let it sit overnight. This morning a new “feature” appeared, a vertical Edge sidebar. Easy enough to get rid of via the sidebar settings, but still, I didn’t ask for it, I don’t want it, so leave me alone MS.
What I do want is for the CU updates to work. I ran sfc with scannow option and was told corrupt files were found and successfully repaired. Dism with the ScanHealth and CheckHealth options (in that order) both completed successfully, but both did say that the ‘component store is repairable’. Unfortunately Dism with RestoreHealth option gave a 0x800f081f error and said ‘the source files could not be found’.
Perhaps the info in the first 3 paragraphs will be useful to someone.
Anybody have an opinion about the CU update failure? Should I try resetting the Windows Update components, or do a repair install as in Topic 6000015?
So after I got rid of the new “feature” (the vertical Edge sidebar), I shut down and then turned the computer on after a couple days. For some reason Windows Update thought I was still running W10 pro 21H2 -apparently because of corrupted files dism couldn’t repair – and offered me a feature update to 22H2 via an enablement package. The update downloaded and installed and after a 20 minute restart, Windows update said I was running 22H2 and was current through the April updates. All seems well. Seems like a fairly strange turn of events but as things seem back to normal, I’ll take it.
Our standard practice is to run RevoUninstaller immediately after updating our Windows computers.
New apps discovered after updating this month include:
Win10 Pro 22H2 secure boot = off After April cumulative update see Event ID 1796 TPM-WMI “The Secure Boot update failed to update a Secure Boot variable with error Secure Boot is not enabled on this machine..” No issues so far. Should I be concerned?
No issues so far. Should I be concerned?
Update – fixed by turning secure boot on
I just noticed this in my Event Viewer also, Event ID 1796.
However, I have never had Secure Boot turned ON, and I don’t want to turn it ON.
Why is this appearing? OK to just let it appear? Doesn’t seem to be causing any issues that I can detect.
Win10 Pro 22H2 secure boot = off After April cumulative update see Event ID 1796 TPM-WMI …
Hi sheldon:
Thanks for posting about this error. I have Secure Boot turned OFF on my Win 10 machine and confirmed my Event Viewer has been logging these Event ID 1796 / TPM-WMI system errors after every system restart since I installed the April 2024 cumulative monthly Quality Update KB5036892 (OS Builds 19045.4291) on 12-Apr-2024 (see attached image).
I sent a bug report to Microsoft using my Feedback Hub app. Anyone who has Microsoft’s Feedback Hub app installed on their computer should be able to view (and upvote) this report at https://aka.ms/AAqfges.

Think about it. Several of our computers are used for administrative activities only and the software used includes:
The printed manuals we use for Office date from 2000 and 2007 and are more than adequate.
No need for “modern software” as along as our security software continues to be supported.
So, the question is, why move from Windows 10 to Windows 11?
No need for “modern software” as along as our security software continues to be supported.
Which modern up to date security software still support XP (or 7) ?
The Windows 7 PC that I’m typing this on is protected by Bitdefender Total Security. In addition, it has HitmanPro.Alert, CyberLock (formerly known as VoodooShield), 0patch, and BlackFog Privacy installed on it.
One of my Vista computers is running Panda Dome and another is on eScan Internet Security Suite. Both of them regularly receive virus definition updates. Panda Dome and eScan still also support XP systems.

Updated 3 Win10 & 1 Win11, all Pro, with Apr patches. No problems seen.
I post this because this is the type of post I look for when new patches show up. If I see a bunch of posts like this, it confirms the Defcon rating. OTOH if users are talking problems & complexity, I delay till next month.
Well, now Microsoft admits it can’t fix the issue for Windows 10 KB5034441 automatically.
Win 10 ver. 22H2 x64
I would do a repair install over the top.
That is so very right!

Hi Susan and Team,
I hope this message finds you well.
I really appreciate your advice and analysis of the changes related to Secure Boot updates. As a consumer base user, what is your advice for deploying these updates? What I mean, they will be mandatory and will eventually enabled to the recommended (and restricted) settings.
While I am in favour of the security benefits they bring, just as rc primak pointed out it won’t be without potential drawbacks. Wouldn’t it be better to start testing now and be prepared?
My most recent system is an HP Elitebook 1040 G9 from early 2023 running Windows 11 23H2. It has BitLocker and SecureBoot enabled in addition to the most recent UEFI firmware available installed I believe this will have the most chance of installing and using these updates.
Thanks in advance for any further advice.
What kind of advice is the HP Driver-and-Hardware-Assistant ! giving you?
In my case HPElitebook 650G10 begin 2024, W11pro-22H2, HP is very strickt in what to update or not.
Mind you to be very strickt and secure about UEFI and Secured Boot changes, in my opinion HP is leading here in changes.
