Windows Activation

Every time we  activate our windows with Microsoft  , all activation stuff is saved in a file called “Wpa.dbl”

We can backup this file so that every time we reinstall windows we don't have to go through the  software activation/registration process again.

How you can do?

Backup the file Wpa.dbl

C:\windows\system32\Wpa.dbl

Go to this location and copy the file before you reinstall windows.
