  1. cannot change the theme

    I work at a school and kids are changing the theme on the computers to all black. When I try to go in to change it back, I cannot click on anything. I did finally figure out how to take it off of high contrast black, but I cannot change the rest back. Nothing happens when I click on it. How are they locking this and how can I undo it??


  2. Win-10 themes keep changing


    Thank you for providing the information.

    • Did you try the steps suggested by Suvarna Govinda above, what was the result?
    As I understand the issue, Themes in Windows doesn't have the options to change on its own. Only the Wallpapers in the themes can change as selected ( Picture, Solid color and Slide Show ).

    I would suggest you to make us understand that if the Wallpapers are changing in Theme which you have selected.

    Below are the steps you can check if it helps.

    • Press Windows + I keys and select Personalization.
    • Select Theme and select the Default theme.
    • Select the Desktop Background below and select the Picture
      and save it and check.
    Please post us back if the issue resolves. We are glad to help you.

    Corrupted Personalization Settings and themes

    Hi Nkhondo,

    Thank you for posting in Microsoft Community.

    I suggest you check if the settings are disable in the registries of the PC.

    • Press
      and type gpedit.msc in the run command.

    • In the window that appears, you can see the "Local Group Policy Editor" Window.

    • In this step I want to Prevent Changing Theme file. You click on User Configuration sub-category Administrative Template sub-category Control Panel sub-category Personalization and click on the "Prevent
      Changing Theme
    User Configuration<< Administrative Template<< Control Panel<< Personalization

    • In this step right-click on the "Prevent Changing Theme"and select the
      edit tab and click on the edit tab.

    • In this step, if you click on the
      Enabled Button then you cannot change the Theme. You click on the Disable Button then you can change the Theme. You click on The Enable Button for Disabling the changing Theme or Prevent Changing Theme.

    • In this step right-click on your Desktop and select the Personalize tab. In this tab you are unable to change the theme after disabling the changing of the theme or Prevent
      Changing Theme.
