Add "Take Ownership" Context Menu

Many folders in Vista are protected from changes and require administrative approval to change every time. Sometimes this can become tedious, so I've created a registry hack you can use to take ownership of select files.

1. Download TakeOwnership.zip (http://mintywhite.com/images/techtips/0804/10takeowner/TakeOwnership.zip). 
2. Add "Take ownership" to your context menu by merging (double click) InstallTakeOwnership.reg into your windows registry. Remove "Take ownership" from your context menu by mergingRemoveTakeOwnership.reg into your registry.
