Stewart,
It looks like your system is infected somehow. None of these three files are
system files:
- - -
regedit.com
cmd.com
regedit32.exe
- - -
Whereas, regedt32.exe is the legitimate file present in Windows\System32
folder. Better run a full system virus scan.

I don't know if a registry cleaner or a virus has rendered commands that
have .com extensions not to work. Either from the Run command or executing
from the windows\system32 folder, they load and lock on the black DOS
screen.
Regedit.com will not run yet regedit32.exe from this folder will run. CMD
has
the same result.
Cntrl-Alt-Delete to the windows security screen, but when choosing
taskmanager it disappears completely.
Will the recovery console fix this?
An overlay of the OP system on the existing?
Or is it a format job.
