Right click to Crash Explorer

While I was removing some old items from the SendTo menu, I noticed that all of a sudden, Explorer crashed when I tried to right click on an icon, or even hit the delete key.

At first I thought it was just the Send To folder, but it crashes if I try to delete an icon from my desktop. But I did successfully remove a few things from the Send To folder before it crashed, so maybe it was something that I removed there? (Although that doesn't really make sense).

I have restarted twice and the problem is still happening. Ever heard of this? Any ideas on what I can do to fix this?

Thanks in advance-
Erik

I think I have it fixed.

I removed a program I recently installed (TugZIP), and had to manually remove some keys from the registry that dealt with shell integration.

Thanks-
