The updates are:
Windows 7 updates --> KB971033, KB978542
Windows Defender updates --> KB915597
Office 2007 updates --> KB981726, KB976321
Maybe one of these updates is the problem.
I rebooted the system without installing the updates above and... everything works just fine!
4 out of 5 updates were published after the problem occured, so it seems the problem is connected with the KB971033 update published on 23rd February 2010.
I've installed all the above updates but KB971033 and system still boots up fine, so that was the problem. I don't know why but this particular update causes problems on system startup.
