I had a problem regarding to freeze on windows7 log on screen in normal boot but there was no problem on safe mode.
So I performed clean boot and enabled all services and startup programs piecemeal. However the issue was solved itself and I didn't figure out what had caused the problem.
Now that I want to enable normal startup, after select "normal startup" and pressing apply the radio button switches to "selective startup " spontaneous. (it's the same about selecting check boxes for Kaspersky in services and startup tabs).
Now I don't have wifi connectivity, audio, display brightness and more.
