Rundll32 and Windows Explorer stopped working

Rundll32 and Windows Explorer stopped working is a common problem in both windows Vista and windows xp. Due to virus or malwares rundll32 and windows explorer may get affected. Here is the solution to this.

Well, the first thing you should do is cover your bases. Run your favorite antivirus and antispyware scanners, and perhaps a few online scans for good measure. Trendmicro Housecall, for instance. housecall.trendmicro.com Then run a chkdsk- Start>Computer>Right click your OS drive (most likely C>Properties>Tools tab>Error checking>Check both boxes>Hit "Check now">Reboot) Update your installation of Vista and your drivers(just doing so in the device manager should be adequate)

Boot off of your operating system CD (after ensuring that your computer will look to the CD tray before the hard drive in your SETUP) and Click "repair your computer", select the correct drive, open the Command Prompt, and type in

SFC /Scannow

(optional: Chkdsk C: /r for another chkdsk) (you can do this within windows, but I like to do it off of the CD for peace of mind)

*note* In my experience, when you boot from the CD, you will have a blank vista background for a few minutes before anything happens. Don't panic!
