I updated hardware in a Dell tower which originally had an Intel i3-4130 and a Dell Inc. 088DT1 A01 motherboard. The updates made it so Windows would not boot, of course. I tried restoring from image backup, but still no boot. So, I installed Windows 7 from scratch, which worked fine. Normally, there is a sticker on the side of the computer box with the Windows license number, and normally I can type that in to active Windows on an updated computer like this. However, this Dell has no such sticker. The installation/repair DVD that came with it likewise seems to have nothing with a license key, nor does the DVD envelop.
Is there a way I can find out what the license number is so I can activate this Windows 7 properly?
