Recently we posted a detailed tutorial to Customize Windows 7 Desktop context menu:
Here is another small tutorial to remove "Next Desktop Background" option from Desktop context menu which appears when you use Desktop SlideShow feature which allows you to run a SlideShow of selected wallpapers.
Personally I don't like this extra option because it makes the whole context menu a bit large which doesn't look good. So here are the steps to remove it:
1. Type regedit in RUN or Start Menu search box and press Enter. It'll open Registry Editor.
2. Now go to:
3. This key contains a sub-key "DesktopSlideshow".
4. Delete it and the option will be removed from Desktop context menu.
PS: If you want a ready-made registry script to do the task automatically, download following ZIP file, extract it and run "Remove Next Desktop Background Option.reg" file to remove the option. There is also a "Restore. reg" file to restore the option.
