I have a Premium Home version of Windows 7 ( genuine version ) that was installed on the computer when I bought it. Over the past few days the system seems to be going to pieces, multiple drivers failing, software not loading and internet explorer constantly crashing or failing to load. In the properties selection of my computer, the usual stuff comes up about about processor/memory/system type etc. and at the bottom I have the Product ID for windows.....however I am now getting constant messages falshing up about " Windows activation " ....The windows 7 home premium key you typed is invalid for activation.... Gives me an option of using .. 1) using the automated phone system 2) Buy a new product key online 3) Type a different product key. Also on the My computer/properties it states " 2 days until automatic activation.Activate windows now " This is still the computer that I had the windows 7 installed upon....but appears it now thinks I have an invalid copy and is trying to stiff me to buy another windows 7 ?
