notice the space then hit enter you will be prompted to insert the disc in the cd-rom and let it go...take about 20 minutes and it will repair all your system files to original condition....if there is an issue about a system error this will fix it..If your problem still continues then it is probably driver or spyware issues. but this will elliminate any of the other problems that could be associated with what troubles you are having.
****this will not work with anything but an original microsoft installation disc******
No it will not do anything to your system except to verify that all system files are in their original condition. That is as it was first installed...It does absolutely nothing to anything else.
