What is the Serial Number, Windows License and Windows Registration Number?
The PC Serial Number is a number that identifies your specific PC from a batch. Somewhere on the case there will be a manufacturer sticker with a part number and serial number. For example: the serial number can be SN-0000-0000-01. The Windows License Number is found either as a sticker on your Computer or with your Windows Software. This number is a 25 Digit number in such a form as AAAAA-BBBBB-CCCCC-DDDDD-EEEEE. The Windows Registration Number is the finalised installation code. This can be found by looking at the control panel in the System Section and noting the 20 Digit Registration Number.
