Manage Activation Of Multiple PCs?

Part of my job is to prepare new laptops for end users that comes from OEMs. Since the included windows installation on most laptops is loaded with "bloatwares" we used to deploy a fresh Win7 Image in WDS and activate using OEM slic which made them completely legal. That was in the Windows 7 days.

Now I'm trying to do about the same thing with Windows 8 however since there is no SLIC it gets a little bit trickier.

Here is what we are doing right now:

-pull the hard drive from the laptop

-make a backup of 'Store' folder

-Reinstall hard drive, deploy Image or Clone from same model.

-pull the hard drive again

-overwrite content of Store folder with the old one

-Change folder permissions

-put the hard disk back in the laptop, let it boot.

-Windows complain about an activation error, reboot or CMD>slmgr -dli.

-activated again.

The hardest part in fact is to take note of which Store folder goes with which laptop.
