I use Windows Vista home premium. Every time when I open the window I got the following error message
C:\Windows\system32\igfxres.dll is either not designed to run Windows or it contains an error. Try installing the program again or contact your system administrator or software vendor for support.
What should I do?

I’m looking for a registry cleaner where I can manually select keys by software vendor for Windows XP. A program called RegCleaner did it for me, but since I have a new pc (also runs XP) it doesn’t work for me.

Now most registry cleaners will scan automatically, but they are quite useless and dangerous to use. Are there any other registry cleaners out there that don’t scan / delete anything automatically but make it easier for me to identify the keys I want to throw out?

Good tip, but I really need one that will clear out the registry keys per software vendor. This one only scans for issues.
