If you remove an installed program and its files by deleting the files, it may still show up in the Add/Remove programs list through the control panel. In order to remove it from the list (so you don’t need to re-install in order to just remove it again).
Start the Registry Editor by clicking RUN from start menu and entering ‘regedit’ without quotes.
Open HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Windows / CurrentVersion / Uninstall
Delete any programs from the list.
This will only delete them from the list, not delete the actual programs. Only programs designed for Windows95 will show up here in the first place.
