Thank you for useful links.
I did increase Disk Space Usage for system Restore Points to 50 gb, it didn't help. Uninstalled antivirus, uninstalled ZoneAlarm, turned off Windows Firewall. Tried "Resolution 1", at the end got message:"System Restore completed successfully" but when I went to check restore points :"No Restore Points have been created". The same story with "Resolution 2". When I typed C:\windows\inf\sr.inf computer din't found it.
I have ISO DVD which I was using for student Upgrade installation Win 7 from XP and i did Repair Disc. Is it possible to do some kind of repair with these DVDs in order to solve this problem but I didn't create system image.
And one more thing: in Event Viewer>System I have error Event ID 25.
