How To change Serial In Windows 7 Pro
I have two Windows 7 boxes that claim to be not genuine. I got them second hand. So I got a genuine serial number and went to input it.
One box doesn't have 'change number' choice at the bottom of the system screen after right clicking 'computer' and then 'properties' - it is just not there.
The other box has one there and doesn't respond. Click all day, nothing happens.
Googled a lot and found a place showing how to use slmgr.vbs from the command box to do it but then it turned out the computer didn't recognise it as a valid command!
What can I do? Got to go for complete reinstalls?
Log in with your admin account and then please see Change product key link not available in Windows.
I may be wrong, but if it is an OEM computer I think you may not see a field to input the new serial.
