NDDU Julius BSIT :
I would like to know how can I activate my laptop using this key which was an OEM key I suppose.
That idiot engineer who fixed my laptop used keygen instead of my OEM key
1. Assuming this system was originally installed with Win 10, you do not need a 'license key'
2. Just do a full wipe and reinstall. It should just activate itself
3. Never, ever patronize that 'idiot engineer' again
Create your own DVD or USB install from here:
