Solved Windows Update KB007215 Install error - 0x800f0831

I have tried to download and install the update in a standalone installer. Will not install.

Tried these running CMD in admin mode...

• dism.exe /Online /Cleanup-image /Restorehealth
• sfc /scannow

Tried these...

• net stop bits
• net stop wuauserv
• net stop appidsvc
• net stop cryptsvc
• Del "%ALLUSERSPROFILE%\Application Data\Microsoft\Network\Downloader\*.*" (this one I cannot get to workI am not sure what I have to change in the string to get it to function...)
• rmdir %systemroot%\SoftwareDistribution /S /Q
• rmdir %systemroot%\system32\catroot2 /S /Q
• net start bits
• net start wuauserv
• net start appidsvc
• net start cryptsvc

I have run the troubleshooter for Win update and it shows me this

Microsoft has created this support article for this case:


If this is a problem for you, perform an in-place upgrade.

I had already created the USB thinking that might be the next step....

I usually go the way of fixing such problems manually, but some things can take time and an in-place upgrade is mostly the faster way.

All fixed. Many thanks

Glad to hear.

You´re welcome.
