# ABR (Activation Backup and Restore)

This is a utility that allows you to backup and restore Windows activation for systems that are pre-installed from the factory by an OEM, allowing you to reinstall the system without having to call Microsoft. It saves the activation to a file and allows you to restore it once you've done a clean install.

How to use it:

2. Run "activation_backup.exe"
3. Save the backup files somewhere safe
4. Reinstall Windows
5. Restore activation by running "activation_restore.exe"

ABR can only be used to install the same version of Windows you have the original OEM license for. For example, if your computer came pre-installed with Windows Home Premium, you can only reinstall with Home Premium. You can, however, switch between 32-bit and 64-bit.

NOTE: For Windows 7 activation, please use the BETA below

## ABR Beta With Windows 7 Support

This is a beta (test release) of the next version of ABR with Windows 7 support. I have had reports that it is working with Windows 7, but I do not have access to OEM versions of Windows 7, so I cannot verify it myself.

If you are willing to try it out, please download here. Please let me know if this worked for you:

Test version with Windows 7 Support: ABRbeta.exe

## Issues with Restore

Issues when running activation_restore are rare, but if you run into a problem, you can register your product key using the following steps:

1. Open a command prompt As Administrator
2. Type, replacing XXXX with the product key in the backup file:
slmgr.vbs /ipk XXXXX-XXXXX-XXXXX...
3. Type, replacing file with full path to file:
slmgr.vbs /ilc C:\path\to\backup-file.xrm-ms
