Copy of windows vista not genuine

[Mark Fuller]

I have a hp pavilion laptop d4 that all of the sudden says that the copy of windows is not genuine. Does the licensed of windows expire after a while?

No, it does not expire. It normally means an infection or a failed MS update.

For the first case, you need to run standard malware tests see here https://www.techspot.com/community/forums/virus-and-malware-removal.28/

But before you start that, just in case of a failed update, try just shutting windows down from the start button, and choose restart in safe mode. Mess about a bit in case Windows needs a bit of time to look around. Run 'chkdsk' in read-only mode just in case there has been a bit of corruption. If errors are reported, repeat as chkdsk /r. Then if all is clear, restart again into normal mode. This has been known to work, and is quick and simple. Good Luck.
