how do i remove an unwanted screensaver (that i cannot uninstall) from screensaver list?

Answer 1

First, try the uninstall method, either by using the Uninstaller which came with the program, or by using the Add Remove button in the Control Panel.

Barring that, Search the hard drive for *.scr. Find the one which matches up to the screen saver you want to get rid of and hten delete it.
