over the weekend, i ran SFC /scannow as part of my routine Maintenace. normally the command returns with ther typical 'no error found' type of message. but this time it said it had found and fixed corrupted files. subsequent passes also said the same thing. i took ma look at the CBS.log, and each time it found an issue, it listed these files, which seem to be related to webview2 -

i tried both 'dism /online /cleanup-image /restorehealth' as well multiple passes of 'sfc /scannow' I also downloaded and did a repair install of Microsoft webview2, which completed successfuly, but did not solve the issue.

i am not sure how to proceed. webview2 seems to be working as it should. is this just a goof up caused by the last windows cum update (KB5043178)? if so what steps should take? or should i just leave it be and let

MS sort it out and publish a fix?

Looks Like MS finally fixed the issue with KB5044384. for those that were having trouble installing the LCU released Tuesday (KB5044284), you need to have windows update repair windows. to do this go to settings > system > Recovery. then select the button marked 'Reinstall now'. Windows update will begin downloading a repair version of you OS. it will also install the LCU at the same time. after windows update finishes repairing your OS, restart. from there check for updates and windows update will find KB5044384 and begin downloading it. Windows will want to restart once it gets installed. let windows restart, then just for kicks, open terminal (or CMD prompt) and run the command 'SFC /SCANNOW'. SFC **should** come back saying "Windows Resource Protection did not find any integrity violations." if it doesn't say that, then you have other issues than the one discussed here in this thread.

(a special caveat: you must be enrolled in Windows insider program to get this update at the 'Release Preview' level or wait a week or two (or more) for the update to roll out to the release for everyone. )

although the link in updates for info about the update produces a Microsoft website 404 error, i was able to find the release notes on the update anyways. here is the link:

Releasing Windows 11 Build 26100.2152 to the Release Preview Channel | Windows Insider Blog

of particular note for this update is this line in the list of fixes:

  • [sfc /scannow command] Fixed: You get errors every time you run the command.

    issue seems to have been compounded with the latest release of the LCU (KB5044284), every attempt to install the update ends in error 0x80073713. according to my research, this error stems from an error in the windows 'store'. on my system my least the only issue is as I have originally posted here, i.e. the webview2 files that are a part of the OS. dism finds no errors, and sfc only finds those files already reported here. all the other updates released on Tuesday installed, except for the LCU. At this point the ONLY workaround *MIGHT* be to perform a clean install and then ensure that the current LCU is installed and not an incremental LCU install. I for one am not going to be thrilled if this turns out to be the only solution to the problem MS caused in the first place with an update. If anyone else with this issue can confirm or deny that they are able to install the LCU or not, it would be helpful.

    Hello Cybot,

    I also tried to upgrade my obviously broken build 26100.1882 to 26100.2033 by installing KB5044284. The installation doesn't work on 30% of my PCs. I can't fix that issue with kb5044284 on these systems. - Iincreasing the size of the recovery partition didn't help like it did with a previous LCU. The installation of KB5044282 worked without errors on 70% of my PCs, the release was changed to 26100.2033 but the WebView2 problem still cannot be solved on these systems either.

    Well, I installed Windows 11 iOT without the Store and have that same error. I read somewhere it was from something with Edge and worried about it
