Defrag moved some system files that should not have been moved.
Now more than half of my programs don't work, programs don't run at startup, even debug tools
don't run. Get a "can't get entry point to SHELL.dll" error with any application I try to run and they
fail.
I have now spent more than 6 hours trying to get my system back to the way it was before
this piece of junk was installed.
