Everytime I start my PC and Windows XP Pro starts up so does C:\WINDOWS\System32 folder. Why? I've looked everywhere I can think of to stop it needless to say without success. It's a minor problem compared with some but anoying.
Another possible reason for the system32 folder opening at startup is you have a registry entry for a startup application which fails to give the path to the .exe file or the path is invalid.
When an .exe file is included as a startup item, but the path does not contain any folder (e.g. the entry is just abc.exe), XP by default looks in the system32 folder for the abc.exe file. If the registry entry contains no such abc.exe file, or the registry entry is null (that is, nothing is written there), XP opens the system32 folder.
Check in msconfig first. Click Start, Run, type msconfig and press Enter. Select the Startup tab.
Look under the "Command" column. If you have an item with no entry under the command column, untick it and click OK. Otherwise, you'll have to check all the paths to the exe files under the command column to make sure that those files exist.
If you can't find anything in msconfig, post back.
