all my executables have changed to run from dos- HELP!

[aveza]

Yesterday, I couldn't run my outside email, when I double
clicked on it, I got a dos window ??
Since then, almost every executable has changed and brings
up a dos window, which of course, dies in a few seconds.
I also can't access regedit to look at the registry, it
says I'm not allowed. I log on as administrator and
everything worked before yesterday.

When I try to associate exe files in windows explorer, I
don't get "open with".

Please help, this is my work computer, and I have a call
in to Tech support, but that usually takes a week or more.

Thanks in advance
Aveza

Have you tried "assoc" command to alter association for .exe?

Also, you need to alter policies, it has disabled you access to change
associations and run Regedit.
