|For those of you suggesting alternatives to MSCONFIG, you |
ignore that there may be a bigger problem.
The first thing you need to do is scan for malware. I
recommend malware/">MalwareBytes' Anti-Malware. Before doing
anything, go to the update tab and make sure you've got the
latest definitions. Then, use the full scan (instead of the quick
scan) and get rid of any nasties it finds.
The next thing you need to do is check your file system. Go
into My Computer, right click on your system drive, and select
Properties. On the Tools tab, do a disk check. Enable all
options and then start it. It'll prompt you to restart your
computer- do that and let it run.
As for restoring MSCONFIG, do what others have already
said. Just remember that it doesn't just disappear unless
there's already another problem!
