I looked on the case , only code is for MS Vista, he updates to Windows 7 premium. I have most of the packing no CD's. I have tried systen restore, it would restore BEFORE the morning of the update. I didn't think that I needed to establish a restore point before this update, because I didn't think I'de need a code !

There is a recovery partition on this HD. I suspect that all the CAB files are here ! This is why I suspect NO need for CD's, no 25 digit product code !!

I'm wondering when he bought and installed Windows 7 if something happened ? I can see that he did it by downloaded it, because I can see the CAB files in a folder, with a bunch of other files that make me think he bought it this way....HMmmm !!?

Thnaks for ALL your help anyhow !!!!
