By default, changing desktop background or desktop wallpaper is easy in Windows 10. You can just right-click on any picture file and click Set as desktop background option to set it as desktop wallpaper. One can also navigate to Settings > Personalization > Background to choose a picture for the desktop background. If you are unable to change the desktop background or set a new picture as the desktop background, you can easily enable changing desktop background by making appropriate changes to Group Policy or Registry. If the personalization section of Settings is displaying “Some settings are managed by your organization” message, it’s likely because changing desktop background has been disabled in Group Policy or Registry. The following are the three easy fixes to enable changing desktop background in Windows 10. Fix 1 of 3 Check activation status of Windows 10 First of all, before checking anything else, please check your activation status of Windows 10 by following instructions in our how to check if your copy of Windows 10 is activated guide.
