[SOLVED] Windows 10 couldn't be installed 80070642-40019

I have being trying to get Windows 7 updates working again after a Windows 10 failed update.

I have ran SFC, Tweaking AIO. Tried a roll back to before Windows 10.

But am at a loss on how to sort it.

This is the error

Fixed,

I followed a post by @Kirby

indows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade\Rollback]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade\Rollback\10.0.10586.0]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade\Rollback\10.0.10586.0\0000]

Deleted any keys linked to OSUpgrade. rebooted and all is now working fine

More than one. Thanks!

Even better! It's always a good feeling when you find a solution to a problem that you can't find anywhere. Even better when it actually helps others.
