I've been getting a "Host Process Rundll32 Has Stopped Working" error for the last week when browsing files on my computer. I've restarted plenty of times but nothing seems to work.
You don't need to get that drastic, as there's a solution - thanks to MS Technet forums
1. Go to computer, your main drive, program files, common files, Ahead, DSfilter.
2. Rename "NeroVideoProc.ax" to say "1NeroVideoProc.ax"
3. Rename "NeVideo.ax" to say "1NeVideo.ax"
4. Reboot
5. Problem fixed.
