Error 0x8004fe21 - Windows not genuine anymore

Hello Everybody,

This is my first thread here so appreciate your patience and understanding.

Some time ago My Win7 Home Premium 64 bit starts displaying a message that it is not genuine anymore. I'm using all the time Kaspersky Antivirus - no any other installed.

I have no idea what has happend and what is causing this. Normally I'm using same applications - nothing new was installed - I can not find any reason why it would behave like this...

Thank You in advance for any help...
