I used REVO Uninstaller to remove a software suite from my XP machine. I used Revo's option to search the registry to remove unwanted entries. (BTW, I recommend Revo highly.)

After Revo was finished, I scanned the registry to look for any entries that had been missed, and I found a whole bunch. These entries now reference software that's been removed from my system, so is it safe to remove all these entries? And if so, can I remove only the entry itself, or should I remove the parent?

I have some knowledge of this stuff, but not in-depth. Can anyone give ma a brief explanation, or, alternativeloy, point me to some good material on the web that explains this?

I would like to re-install the software I removed, and I'm concerned about introducing confusion after I do it, since I fear that some items in the registry might be duplicated.

Hi :thumbsup:.

To answer your question...there is no problem with manually removing software registry entries that you are sure are history.

I occasionally do this, although I don't make it a habit because I don't think it's that important to do this sort of elimination.

Most software will simply overwrite any existing registry entries, in the same way that files with the same name will overwrite other files that already exist when moved to that folder.

Occasionally, you run into a program where it's essential to remove all previous traces...to get an install that works properly (Symantec programs come to mind) but this is not normal.
