Windows 7 nog legit

Hello,
Yesterday i installed new windows updates (1) and after a restart windows detected that it is not a legit version. i downloaded the latest version of windows loader and activated it again. After a restart it seemed fine but today when i started windows i got the same message again and a black background. Also Microsoft Security Essentials is complaining to me about windows not being legit. How do i fix this?
Thanks in advance and sorry for bad / simple english.
