How to manually backup and restore Windows 8.1 RTM activation I create this topic about manually backup and restore Windows 8.1 for you guys you do not need rely on any third party software when you need to reinstall your Windows copy, you can easily do it yourself. Other reason is still early age of Windows 8.1 RTM non of the backup and restore software not functioning at the moment. Important Points you need to know before backup and reinstall procedure: 1. The activation is tied to your specific hardware and OS edition, so keep this in mind. 2. The solution will likely 100% fail if you make changes to hardware and re-install Windows and then trying to restore activation again 3. It has come to my attention that installing certain hardware drivers will break the activation on Windows 8 forcing you to reactivate. One way to prevent this from happening would be to make sure everything is installed and up to date before activating and then take the backup. That way when you have reinstalled Windows and the hardware drivers it should work just fine restoring activation later. 4. Once we buy the retail version of Windows 8, backing up the activation would be a more permanent solution given that you don't change the hardware or OS edition along the road which means you have to reactivate and backup again. 5. This manual backup and reactivate methot was working on KMS Activation but as there is non working KMS Activation i just can not check at this moment however there is no reason why shouldn't if there is in the future.
