I just performed a Windows 7 Home Premium to Windows 7 Ultimate Anytime Upgrade, and when I went to check if everything was still working fine (Which it was!) I came across this when I right clicked Computer > Properties. It says 3 Days until automatic activation, does that mean that my key is invalid? I'm just curious if that's what it means of it it means it will automatically activate itself again in 3 days, please help, thanks!
you need to enter a windows ultimate product key. home premium keys wont activate windows ultimate.
the ultimate key should be on your windows disk /booklet if you have 1, if not then you will have to downgrade to premium.
