I tried
sfc /scannow
but it does not asking for CD
And I found one more error in windows now.
When I pushing F3 for searching eller starting search function it showing error that some file are missing and probaly must be reinstalled.
I downloaded windows script 5.6 and installed it but without any result too.

I dont want to do reinstall whole windows becouse it takes a lot of time and I need to make backup of all school work that takes few CDs.
