This was tricky to find an answer to but before trying make sure that you backup your Registry.

The fix for this, from Kelly's Korner, isolates the registry
entries for the Add/Remove Programs window, at:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Uninstall\

It suggests that the white space is caused by a sub-entry of
that registry folder in which the program has an entry for
Display Icon which contains a negative number for the icon:
"C:\Program Files\Logitech\IM Video Companion\VideoIM.exe",-1
for example. Not all programs will have a Display Icon entry,
so it might not take too long to find the one that does. The
icon number should be a positive number, so just eliminating
the negative sign should work, or, if not, you could just
delete the Display Icon entry for that program. The rest of
the information should still load.

If your display does not have a large white space, followed
by other programs, but is rather a situation where the page
simply stops loading, this may not apply.
