Windows 10: Can not Activated my Windows 10/ Might be because of deleting old Windows folder

Hi! I changed my Windows 7 to windows 10 , two days ago. Originally my Windows 7 was a purchased version so I had no problem upgrading to windows 10 and activating it.

But the problem started when yesterday I erased all my Old Windows folder from my System because I thought I do not need it anymore.

(It was a long process too)

I think apparently my product key and other info was related to the Old Windows folder too.

Now I get the error - notification that I need to Activate my Windows. when I click on Troubleshoot it says I gotta purchase it or change My Windows 10 Pro to Windows Home.

What should I do?

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

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

C windows installer folder - Delete?

He can do symbolic link redirection and move the files in it to a different location. *Wink
Better try it out in a virtual of first. Just a suggestion.

Like:
First move everything in c:\windows\installer to d:\installercache
Then delete c:\windows\installer folder
Then type this in command mode as admin
mklink /d c:\windows\installer d:\installercache

Removing those installer files is a bad idea. it might prevent you from updating or uninstalling apps.
