Help Windows 10 no updates two computers
 

Your thoughts most welcome on a problem I am meeting with updates. Two computers, one PC and one laptop at different locations, different service provider. Running genuine Windows 10 Home edition. Both computers have been out of use for several months. Both computers are not updating.

The PC no longer has a list of updates just recent 47 updates on reactivating Windows. I have attempted to update my PC manually from Microsoft updates listing back to January 2025. Apparently June 25 was critical security update. None of this worked.

SFC does not run when selected as admin. It shows on the screen momentarily. Virus scans show no problems on router and both computers. That's with two different browsers and antivirus turned on and off.

Any thoughts?

In the end I had to do a clean install as Windows no longer recognised my PIN and Internet was locked out so could not get the Microsoft app for lock outs. As Admin my password was said to be incorrect, Windows log in a no go and Microsoft account password said to be incorrect. Having the Windows 7 overlay on the computer turned out to be a disadvantage to alternate access to troubleshooting. Some data and files were lost as reinstall choices did not allow repair. Overall the effort and updates took 4 hours.

You will need to do it all again in a few months.

2 things:

1) Never let the default installation login credentials be a Microsoft Account, always create an offline local user / admin account.
2) Have a bootable Knoppix LiveCD device (USB / CD / DVD) to be able to reset local passwords. Works up to Win10, not tried it on 11.

You will never be locked out of a Windows system again.
