set back to an image and lost activation

System Image Backup in Windows 7

What does that contribute to the discussion?. I have been imaging with most any imaging product out there - including that one.

Means if you use wdsimagebackup then you should not have problem ...IMO ...

I use the built-in Backup utility to image my system. I recently restored it to about 8 months ago and it prompted for re-activation, which I did. No clue why, like everyone else, but it also happened using this built-in solution.
