same old question. Since hardware upgrade Win activation wont accept my product key. If I run the cmd slmgr -dli commend it returns the correct partial key.

need to activate win 7 to upgrade to win 10 but refuses to accept product key

hey all,

just got a hp mini from ebay, came with win 7 starter key. installed and entered the starter key as it won't let me upgrade to win 10 unless I activate win7. I've received error message that my product key is invalid for activation. So it wont let me upgrade
to win 10 until i activate win 7 but it won't accept the product key for win 7 and activate it. Anyone got a fix for this? I'm a nurse and really need a working computer rn.

Cheers

Rory
