Either an unauthorized change was made to your Windows license or a software program installed on this computer is not currently compatible with Windows Vista.
Your problems derive from one of these issues.....If you haven't installed any new software lately that may have contributed to the issue, then your best bet is to contact Microsoft and run through a phone validation procedure with them.
If your copy of windows is still deemed non-genuine by MS, you probably need to have an urgent talk with the supplier of your system and find out why this is so. It could just be an issues with the suppliers Vista Retail licensing conditions affecting their ability to issue genuine keys.
Good Luck
