Control Panel\All Control Panel Items\Personalization on windows 10 pro

Hi,

What exactly happens when you try to change the theme? Do you receive any error message?

If you have any third-party desktop customization software installed on the computer and if it is restricting you from changing the desktop theme, I would suggest you to first uninstall it from the computer and check if that resolves the issue. Please try this method:

Method 1: Uninstall any third-party Desktop Customization Software

Follow these steps to uninstall this software from “Programs and Features”.

a) Press “Windows Logo” + “X” keys on the keyboard and select “Programs and Features” from that menu.

b) In the “Programs and Features” window, search for the desktop customization software and then click on it.

c) Select the option “Uninstall” to remove the program from the computer.

d) Follow the on-screen instructions to complete the uninstallation process.

e) Restart the computer and check if the issue persists.

If the issue still persists, then try the next method.

Method 2: I suggest you to run System File Checker (SFC Scan) as this could be an issue with corrupt system files. System File Checker is a utility in Microsoft Windows that allows users to scan for and restore corruptions in Windows system files. Refer to the following link:
