I’m sure manu of you have tripped an error when activating one of your Media Center plugins and then received the prompt that allows you to place a check in the box, actively disabling that application.  Am I right?  Well, I’ve seen it asked quite a few times, so I thought I would add to the Google search pile by adding the solution for those of you who want to re-add that application because you accidentally checked that little box and hit “OK”.

This is for Vista, but I assume 7MC is probably pretty much the same:

1. Go to Tasks
2. Go To Settings
3. Go to General
4. Go to Program Library Options
5. Click on Edit Program Library
6. Place a check in the disabled application’s box and hit Save

You can also disable any applications you want using this method simply by removing the check in the box.
