I have recently had a laptop sent back to supplier for fixing a mainboard fault.

I got it back today and every time it boots up I am faced with:

"Setup is preparing windows for first time use"

Then once it gets to the desktop I get the sysprep dialog come up asking if I want OOBC or Audit actions. I can close it, but it just keeps coming back, and I cannot find any startup or boot actions, even downloaded autoruns, and that cannot find anything to do with it.

Ideally I do not want to format/fdisk as I have just spent hours installing everything on the laptop and I have my primary C:/ which has all windows and at worst case I can get rid of that, but I have a secondary partition D:/ which has alot of stuff I cant lose as its work related and important.

Also to make matters more difficult I do not have a windows 7 disk, it was just pre-installed and they dont provide a disk.

Any help would be great!
