Removing extra entries in the Windows Add/Remove programs list

QUESTION:
On Windows, I've noticed that upgrading creates a new entry in the Add/Remove Programs dialog box, instead of replacing the old one. Is there a way to remove the extra entry?

ANSWER:
This is an existing issue (#6596) with the installer.
When you upgrade from release to release, it does not remove the old entries, so that even though it is installed only once, it appears to be installed multiple times.

If you are comfortable editing your registry (good idea to back it up first), then you can get rid of these extra entries.
For example, assume that AccuRev_3.3.1 is an extra item in the list you want to remove. You would delete the registry keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Management\ARPCache\AccuRev_3.3.1
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\AccuRev_3.3.1

Delete those two keys for each extra item listed you want to remove.
