In Windows you can change desktop wallpaper, screen saver, themes and other appearance settings by right-click on Desktop and select "Properties".
Sometimes you might want to disable all or a few options in Desktop Properties to restrict users or you might want to enable those options in case they are disabled by your system administrator or a virus infection.
Following tutorial will help you in enabling or disabling all or a particular option in Desktop Properties:
NOTE: This tutorial will work for almost all Windows versions.
A. Disable Themes Tab in Desktop Properties:
Type regedit in RUN dialog box and press Enter. Now goto:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ Explorer
If "Explorer" key is not present, then create it. Now in right-side pane, create a new DWORD value NoThemesTab and set its value to 1 to disable it.

B. Disable Desktop Tab in Desktop Properties:
Type regedit in RUN dialog box and press Enter. Now goto:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ System
If "System" key is not present, then create it. Now in right-side pane, create a new DWORD value NoDispBackgroundPage and set its value to 1 to disable it.

C. Disable Screen Saver Tab in Desktop Properties:
Type regedit in RUN dialog box and press Enter. Now goto:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ System
If "System" key is not present, then create it. Now in right-side pane, create a new DWORD value NoDispScrSavPage and set its value to 1 to disable it.

D. Disable both Themes and Appearance Tabs in Desktop Properties:
Type regedit in RUN dialog box and press Enter. Now goto:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ System
If "System" key is not present, then create it. Now in right-side pane, create a new DWORD value NoDispAppearancePage and set its value to 1 to disable it.

E. Disable Settings Tab in Desktop Properties:
Type regedit in RUN dialog box and press Enter. Now goto:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\ System
If "System" key is not present, then create it. Now in right-side pane, create a new DWORD value NoDispSettingsPage and set its value to 1 to disable it.

BONUS TIP: In case you want to enable a restricted tab in Desktop Properties, just delete the required DWORD value as mentioned above or change its value to 0 instead of 1.

Thank you for your help. I managed to get my Display Settings enabled through following all the steps. And I was so happy that I wanted to download a really nice screensaver, and googled to fin d one, the first one on the list I clicked and...you guessed it, lo and behold I managed to click on the same virus Antivirus XP 2008. However, I quickly clicked Trend Micro and got rid of it. This is the most nasty virus I have ever had, but then I have never had a virus before in my computer. Thanks a lot again, and I will certainly contact your website if I need further help. Now I am going to click on the link to make my Vista faster.

Dear Vishal,
Could you direct me to the place i need to go in order to prevent right clicking an image file and setting it is the desktop wallpaper?
I have looked but the registry is so vast and words are not always how i would think they are.
