Backup And Restore Windows 8 Activation


This article explains how to backup and restore an activation license of Windows 8. You need to backup and restore an activation because every time you format and reinstall Windows you need to activate Windows again. For activation you look for a valid MAK key, calling Microsoft or waiting for a KMS server to go online etc. Sometimes when you activate Windows with a previous key then you have a problem with activation and get the error message "This key has limit of activation".

But if you want to reinstall Windows and don't want to lose the activation then you can create a backup of the activation and then reinstall Windows then restore the activation. This activation method backs up and restores the Windows 8 activation as well as Microsoft Office activation.

This method only works on the same machine, the same Windows edition. Before activation, the machine hardware should not be changed.
