Tonight however I have had a warning message come up saying my windows 7 installation was invalid due to invalid or incorrect product key and inviting me to purchase a new one. This cannot be right. I put in the product key attached to the computer and it was accepted when I reinstalled.
What is going on? Does it have something to do with upgrading to 10 and then going back an 'unofficial' way, meaning my key has been invalidated? Or is this some form of scam? I have full security on the machine, Norton 360, Antispyware, antimalware etc all up to date and scans run recently.
Can anyone help please?
The PC is an Asus K53E. Windows 7 Home Premium.
