I have a Dell Studio XPS that is several years old but was fully functional until after I had to replace both hard drives in an array only weeks apart. Now I get "Not genuine Windows" messages daily, can't update Windows because update service not ON error message when it is ON and even when restarted.
I presume it's because the EOM license (original from Dell) code doesn't match with Microsoft records when activated after replacing the second hard drive.
Any ideas on how to get things working again? Win 7 was a Dell supplied free upgrade to Win 7 from XP.
