I'm getting the same issue I had before with the previous (now pulled) KB5016243 update. I ended up manually installing the previous KB5016243 update using the .msu file.

That one still shows as installed on my system, so I will try to uninstall it and then see if this one goes through. Error code on the installation of this update is 0x800701a1.

Same issue as you. I also had to manually install the update and it happened on the past patch as well. I wonder if more people are having this trouble?

IMHO, this update doesn't really seem ready for release to the general, non-techy public. I've put my updates on pause for a while in the hopes that MS will refine these compatibility issues before I'm forced to update.

I wonder if its possible to switch all these ( two) features off ( .NET) , after a succes-full install of the updates.
I just dont use them , and slows down the OS , by installed services and folders ............

.NET files are libraries, like DLL's, of pre-written functions that some apps use in order to run. If a .NET library isn't used by any running apps, it just sits there unused. .NET libraries therefore do not have ON/OFF switches. They are only loaded into memory when needed.

OK , good to know.........
Remains my question ; does my PC keeps working , after the latest updates , if we switch these two .NET-functions off ?
They were neccesary for installing the latest updates .............do we still need them ?
I never used them before , untill these updates !

TraderGary · May 13, 2022

Microsoft Windows apps use the functions in .NET libraries in order to run. Again, a .NET library does NOT have an ON/OFF switch. If a .NET library file isn't being used, it just sits there like any other file on your computer. A .NET library file is only needed and loaded if you run an app that uses the functions in that particular .NET library file.

I have two supported devices running W11, one has .NET Framework 3.5 enabled in Windows Features, the other does not. Both have .NET Framework 4.8 which is enabled by default in a standard W11 install or upgrade.

Both received the KB5013943 update without issues.

I was not aware that a .NET framework could be enabled/disabled. I don't know if a disabled .NET library would be enabled if an app needed any of it's functions in order to run. I retired as a Microsoft Windows Applications engineer 25 years ago. My knowledge could obviously be a bit out-of-date.

Well , best way to find out is ; by just trying..........
Will switch off the two features under .NET 3.5 and see what happens .

The current version of the .NET Framework is 4.8. If you have any apps that depend on older 3.5, they will undoubtedly no longer work.

Both 4.8 and 3.5 are a standard part of any W11 install, with 4.8 enabled by default. I enabled 3.5 on this particular machine as I have some older apps that required it.

Just like the VC runtime libraries, the .NET code is only loaded and run when an app that requires it asks for one of its functions.

Well , just tried ...........DONT switch the two "foundations ,HTTP,non-HTTP " off !!
If you do , this kb5013943 will be installed , again..............

Then how (?) could you update , without these two items I ( and a lot of other people also ) , could not update ! When I switch them off , it starts the update again .
Maybe coz I upgraded from 10 , so no "clean install "..........

Senecio · May 13, 2022

Just to add to the general mayhem surrounding this update... I can report that after getting it to work with .NET 3.5 'turned on' in Windows features, I found that 'turning it off' which means uninstalling the .NET libraries caused the same problems with not being able to run Event Viewer etc. So I turned the .NET 3.5 back on. However, yesterday I noticed one of MS's stealth upgrades going on (recorded in Event Viewer) and I wondered if this was a 'hotfix'. So today I tried turning the .NET libraries off again, rebooted, and sure enough everything is now working.

This was on my laptop. Just to be clear, my Desktop, which had no problem installing the update did not get the MS stealth download. So if you have the problem, it might be worth leaving the .NET libraries installed for a bit, then trying to remove them again and check to see if your apps are working.

Not enabled here either and upgraded from 10.

" check to see if your apps are working. "..............after turning these two items off ( in features) , under .NET 3.5 , all works fine still .................only ; MS tries to install this kb5013943 again !!
While its already installed ........

So , I have to keep them enabled , never used them before , now only for this ( terrible ) update !

I can only say that it's not trying to reinstall itself here. If I had that issue, I would probably try: 1. pause updates for a week. 2. Uninstall kb501943. 3. turn on .net 3.5 4. turn off the updates pause and reinstall kb501943. 5. turn off .net 3.5. This is based on the suspicion that maybe the kb501943 which is installed on your system is in some way corrupted, which prevents windows update from recognizing it as being installed. So uninstalling it and reinstalling it might enable you to get a clean installation. Good luck.

My Dell XPS 15 9510, you can see my specs in "My Computer" below, was brand new this year on Feb 23, 2022.

My .NET Framework 3.5 was never activated. Only 4.8 was activated.

I've had no problems with the update.

My W11 Pro came with my computer, and I've not done any mods or add-on apps to make it work like W10.

Applies to	Symptom	Workaround
IT admins	After installing the Windows updates released January 11, 2022 or later Windows versions on an affected version of Windows, recovery discs (CD or DVD) created by using the Backup and Restore (Windows 7) app in Control Panel might be unable to start. Recovery discs that were created by using the Backup and Restore (Windows 7) app on devices which have installed Windows updates released before January 11, 2022 are not affected by this issue and should start as expected. Note No third-party backup or recovery apps are currently known to be affected by this issue	We are working on a resolution and will provide an update in an upcoming release.
IT admins	After installing this update, some .NET Framework 3.5 apps might have issues or might fail to open. Affected apps are using certain optional components in .NET Framework 3.5, such as Windows Communication Foundation (WCF) and Windows Workflow (WWF) components.	You can mitigate this issue by re-enabling .NET Framework 3.5 and the Windows Communication Foundation in Windows Features. For instructions, please see Enable the .NET Framework 3.5 in Control Panel. Advanced users or IT admins can do this programmatically using an elevated Command Prompt (run as administrator) and running the following commands: `dism /online /enable-feature /featurename:netfx3 /all` `dism /online /enable-feature /featurename:WCF-HTTP-Activation` `dism /online /enable-feature /featurename:WCF-NonHTTP-Activation`
All users	After installing this update, Windows devices that use certain GPUs might cause apps to close unexpectedly or cause intermittent issues that affect some apps that use Direct3D 9. You might also receive an error in Event Log in Windows Logs/Applications, and the faulting module is d3d9on12.dll and the exception code is 0xc0000094.	This issue is resolved using Known Issue Rollback (KIR). Please note that it might take up to 24 hours for the resolution to propagate automatically to consumer devices and non-managed business devices. Restarting your Windows device might help the resolution apply to your device faster. For enterprise-managed, devices that have installed an affected update and encountered this issue can resolve it by installing and configuring the special Group Policy listed below. For information on deploying and configuring these special Group Policies, see How to use Group Policy to deploy a Known Issue Rollback. Group Policy download with Group Policy name: Download for Windows 11, version 21H2 - Group Policy name: KB5012643 220509_20053 Known Issue Rollback Important You must install and configure the Group Policy to resolve this issue. Please see, How to use Group Policy to deploy a Known Issue Rollback.
IT admins	After installing updates released May 10, 2022 on domain controllers, you might see authentication failures on the server or client for some services. These services include Network Policy Server (NPS), Routing and Remote access Service (RRAS), Radius, Extensible Authentication Protocol (EAP), and Protected Extensible Authentication Protocol (PEAP). An issue has been found related to how the domain controller manages the mapping of certificates to machine accounts. Note Installation of the May 10, 2022 updates on client Windows devices and non-domain controller Windows Servers will not cause this issue. This issue only affects servers that are used as domain controllers.	The preferred mitigation for this issue is to manually map certificates to a machine account in Active Directory. For instructions, see Certificate mapping. Note The instructions are the same for mapping certificates to user or machine accounts in Active Directory. If the preferred mitigation will not work in your environment, see KB5014754—Certificate-based authentication changes on Windows domain controllers for other possible mitigations in the "SChannel registry key" section. Note Any other mitigation except the preferred mitigations might lower or disable security hardening.
