Making your Windows more private

We can use Registry to do that.

A.
1. First of all go to Start>Run, then type: regedit

2. Go to HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Policies
3.  Rightclick on Policies>New>Key>name it into ActiveDesktop

4.  Make a DWORD value in ActiveDesktop, Rightclick in ActiveDesktop. Choose New. Choose DWORD Value.
5.  Name it into NoChangingWallpaper.  To make it active, Doubleclick it, then you should change the value into 1

If  you've done, you must log off then log on again  Then another user can't change your wallpaper.

And These are another tricks :
