Windows 10: Windows 10 not re-activating after desktop lost power

I had my PC in sleep mode, and someone tripped a breaker. The computer shut off, but nothing important was unsaved. No biggie. Unfortunately, Windows 10 64-bit home edition now thinks that my PC is a totally different computer; no hardware change, no other computers with the same product key, but I somehow need to re-activate windows. My copy of windows 10 is not linked to a Microsoft account, and there are no other devices linked to my Microsoft account.


Thanks, Microsoft.


What do I do now?

:)

 

windows 10 deleted my desktop files

Step 1 - I upgraded to Win 10 and lost all my files on Desktop.

Step 2 - Found the files in Network - USers- Desktop

copied all files again to desktop.

Step 3- Restarted my machine again and lost desktop files again.

Step 4 - As suggested did the following as listed below but dont find my files.

• Press “Windows + E”, open This PC/Computer
• Open Local Disc C, open Windows.old
• Click on Users, select your User name
• Go to desktop folder

Cant find my files. Why is Win 10 deleted files again and again from Desktop ?.

 

Lost desktop background

The thing is I have no spyware; I've done scans with different pieces of software and they all confirm this. The active desktop bit that was removed by Search & Destroy is, I think, a pure Windows thing and I've seen it being listed in Search & Destroy scans on both this and other PCs before.

The thing is that this time I was trying to be clever and pressed "delete" whereas before I just ignored it. I've undone the Active Desktop removal in Search & Destroy and also followed your tips above but it makes no difference - still no desktop background. Any other ideas or do I just wait until the next reformat?

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
