Visual Studio Just-In-Time debugger error?

Okay, I keep getting these debugging errors whenever I open a folder on my desktop. Here is the exact message:

Visual Studio Just-In-Time Debugger

 An unhandled win32 exception occurred in explorer.exe[3316]. Just-In-Time debugging this exception failed with the following error: No installed debugger has Just-In-Time debugging enabled. In Visual Studio, Just-In-Time debugging can be enabled from Tools/Options/Debugging/Just-In-Time.

Check the documentation index for 'Just-In-Time debugging, errors' for more information.

The problem is, I don't HAVE Visual Studio so there's not much I can do. I've been looking all over the net and I keep hearing something about putting in the command for drwtsn32 -i but when I do that I get another error. I've had my computer for 3 years and nothing like this has happened but over the past couple of months I've been getting debugging errors, and this is the most recent.

 I'm not very good at going into the registry and stuff, so if people can help me out that would be great.
