Ok, i repaired the computer using the repair tool as it was said on that link, and used the sfc /scannow command. This time, i got no problems. Now, i will install the updates, and if problems occur again, i will not hesitate to post here. Thank you for your help!(i could not run a clean install because in those 3 days i have installed a lot of programs, and it would take a lot of time again to reinstall them, sorry)
