Endless Corrupt Files and Troubleshooting.

Yesterday my SFC /Scannow command, run from Powershell Admin found corrupt files it was unable to fix.  I expected The Dism /Online /Cleanup-Image /Restorehealth command to take care of it.  Instead it reported "error 0x800f0906" and said it lacked the files to repair the problem. 

I looked up error 0x800f0906 in a Dism command.  It suggested a repair that started and stopped services, a

net stop wuauserv

cd %systemroot%\SoftwareDistribution

ren Download Download.old

net start wuauserv

net stop bits

net start bits

net stop cryptsvc

cd %systemroot%\system32

ren catroot2 catroot2old

net start cryptsvc

It also suggested Windows Update was malfunctioning and that I should fix it from The Troubleshooting screen.  I did, and SFC /Scannow came up clean and Dism /Online /Cleanup-Image /RestoreHealth reported error code 0x800f081f instead.

I then used The Dism /Online /Cleanup-Image /StartComponentCleanup and The Dism /Online /Cleanup-Image /StartComponentCleanup /ResetBase Commands.  I then used The Dism /Online /Cleanup-Image /ScanHealth Command and it reported "No component store corruption detected."  I thought I was in the clear, but  Dism /Online /Cleanup-Image /RestoreHealth keeps reporting it found and repaired files and The Troubleshooter keeps reporting it's fixed problems in Windows Update.  Probably not the biggest deal in the Windows world but a little unsettling.
