Registry Key Recover

[Elephantman5]

I was uninstalling a prog that had a trojan in it. I deleted the registry keys and such; manuelling removing it because the Explorer.exe would shut down every time I tried to do it the old fasion way Wink

So, I was going through, and I accidentally deleted the Uninstall registry key

Which has led all the installed progs to not show up in the Add/Remove Programs gui that's in Control Panel.

And so, I am wondering if I have to wait until tommorow to do this, when I have the windows cd. Or if I'm able to just do some other recovery.

I restarted and held down F8, and did the "Last known good configuration" thing, but it said I had to replace hal.dll.

I've downloaded the dll file, but I'm not very sure I want to replace it because I don't want to mess up the computer that is not even mine worse. Wink

And so...

What am I to do in this dillema?

The programs work; obviouslly, I'm in Firefox at the moment. I'm going to be running a scan, of course, and already have, but I'm defintelly sure it wasn't the virus that did this; but my fat fingering talent of screwing things up worse then they already were. Smile

Oooooh. NOT good. You didn't back up the registry first? Maybe there's a system restore point somewhere. Yeah, not being able to uninstall stuff is bad. What exctly resides in this key? Could it be recreated somehow?

I'm under the impression that it's

this key.

Will have a copy of windows pretty soon, but...I'm really worried about it.

So, it's basically centered around the Windows Add/Remove Prog menu not populating. This is the result, explicitly, of a registry deletion on my part.

I've gone around a little on the link I gave you, but I'm not understanding;

I see what they're showing me to look for in replacement.

Doesn't make sense really. It's a default key that SHOULD go with windows, therefore should be a necessary; therefore I should be able to simply fix it with an XP repair...

Right?

I'm able to uninstall through the the executables that come WITH a prog (I did it), but not able to find the prog even LISTED in the list.

No I did not.

As a clarification here...

HKLM,"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\

This is the directory.
