Thanks,

But there is no "Change Product Key" option. I did (once) get a dialog, on start up, that gave me the option to enter an activation key. But when I click on the option, I got a error saying that it could not locate the application to enter the key. This problem is not only on my home machine. I have seen it on several machines. It seems to occur between 3 to 6 months AFTER the activation key has been entered. Then Most of the system application stop functioning, including the activation method. Our IT person has called MS, and performed the activation procedure. Everything would work fine for about 2 or 3 days, then the machine would become Not Genuine again.

I am thinking of going back to XP. This windows vista/7 crap is really begining to P!SS me off.

Try building a web site, but the computer will not run IIS, or SQL, or any system level operation. I get better perforance from the Home edition then I do from the Professional.
