To remove a plugin, if you have the xml file that comes with it, for example plugin.xml is the filename:
1. Open a cmd window
2. go to %windir%\ehome directory
3. registermceapp /u plugin.xml.
If that plugin is registered for all users then you should use "registermceapp /u /allusers plugin.xml" as administrator, instead.
You can also rip them out of the registry at:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Extensibility\Appications
And if they are on a strip besides in the Extras then also here:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Extensibility\Entry Points
