Disable share my desktop

Hi, when ı speak (voice and cam) with Windows live messenger, my friends see my desktop, how can ı disable this?

 

Group policy (gpedit.msc)

(Do not have NM installed nor do I intend to touch it ever, so cannot tell you whether it can be done in the program itself or not.)

 

How can ı stop uscreencapture ? This file under c:\windows\system32

Operating system vista.

 

No idea what are you asking about, plus all this stuff would better be asked in a MS-related forum.

 

do you need uscreencapture? If not remove it via Add/Remove progs. Or use MS Autoruns util to disable it from starting when you login onto computer
