On startup, Windows 10 pops up the following alert:

An error has occurred in the program during initialization. If this problem continues, please contact your system administrator.

Error code: 0x800b0100

Windows is up to date and I've done my research, but sfc /scannow and dism /Online /Cleanup-Image /ScanHealth didn't fix the problem - the former just reported that there were corrupted files, not how to restore them (the resulting CBS.log is several megabytes in size and not very helpful either).

The same error pops up whenever I try to access Windows Defender via the start menu - however, both services.msc and the Windows Defender section within Windows Settings report that the respective services are active.

a) Can I safely assume that the machine is properly protected?

b) How can I get rid of this annoying dialog?

I'd very much appreciate any help.

    run this command to fix the issue: dism /Online /Cleanup-Image /RestoreHealth – magicandre1981 Nov 19 '17 at 15:38
  • Thank you. Unfortunately, it doesn't make a difference; afterwards, the error pops up just as before and sfc /scannow still reports corrupted files. (Sorry for the late response; this isn't my machine, I only have access to it on weekends.) – AnC Nov 25 '17 at 14:40
  • look in CBS.log which files can't be repaired – magicandre1981 Nov 25 '17 at 16:51
  • That log is several megabytes in size, ~40k lines - anything I could search for? (Terms like "corruption" don't yield much useful information, or perhaps it's just too cryptic for me to understand.) – AnC Nov 25 '17 at 17:08

    open cmd.exe as admin in C:\Windows\Logs\CBS and run findstr /c:"[SR]" CBS.log > sfcdetails.txt now open sfcdetails.txt and look which files can't be restored – magicandre1981 Nov 26 '17 at 16:33

It is recommended you to fix this problem, instead of ignoring it. Try below suggestions.

Re-start system in Clean Boot - Perform a clean startup to determine whether background programs are interfering with your game or program: https://support.microsoft.com/en-us/help/331796/perform-a-clean-startup-to-determine-whether-background-programs-are-i

>the former just reported that there were corrupted files

If both SFC and DISM.EXE reports error about system files. If there is system backup available, just restore system back to previous working state.

Besides, you can try - How to: Perform a Repair Upgrade Using the Windows 10 ISO file Important thread: https://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install-winpc/how-to-perform-a-repair-upgrade-using-the-windows/35160fbe-9352-4e70-9887-f40096ec3085

  • Thank you. Unfortunately, Clean Boot doesn't make a difference; running the same commands again, the error pops up just as before and sfc /scannow still reports corrupted files. There's no system backup I could restore either, so I'll try the Repair Upgrade and will report back.
