MARK/RELEASE (of late Turbo Power Software fame f.e.) are one of those
utilities. Unfortunately, such tools don't work in all cases, as some
TSRs patch around in the running system and hook into backdoor entry
points in the operating system. Forcefully uninstalling them via
external tools and releasing their memory may cause some pointers
or vectors point into nowhere's land - causing a system hang soon
later...

Microsoft's MSCDEX utility is one of those TSRs, which patches around
in memory and thus cannot be safely unloaded using such utilities.
(NWCDEX is safe).

Greetings,

 Matthias
