Windows 8 "Change PC Settings" Not working
Welcome to the Microsoft Community and thank you for giving us a chance to assist you.
It can be very frustrating to not be able to use the computer properly. I see that the Store app is missing and you are unable to access the change PC settings menu.
Please answer these questions so I get a better understanding of the issue.
1. Do you get any error code or error message on startup?
3. Have any changes been made to the computer before this issue occured?
You can try these methods to check if the issue gets resolved.
Method 1: Run the app troubleshooter.
Open that link to run the troubleshooter.
a. Press "Windows key + R".
b. Type "wsreset.exe" on Run the window and press enter.
Method 3:Check if the issue exists in clean boot.
Follow the steps here to troubleshoot the issue. Once you are in clean boot check if the
settings menu works and see if there is something that conflicts with it.
Note: Once troubleshooting is done please follow "Step 3 :Reset the computer to
start as usual" on the article to boot the computer in normal mode.
Method 4:Run a System File Checker scan and check if that helps.
Refer to the following steps to run SFC scan.
a)Move the mouse pointer to bottom left of the screen where you see preview of start menu and Right-click to bring up a list of Windows settings.
b)Click on ‘Command Prompt (Admin) to bring up elevated command prompt. Note: Click ‘Yes’ if it prompts for permission.
c)In the command prompt type in the following command: ‘sfc /scannow’.
If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected. For example, some Windows functions may not work, or Windows may crash. The System File Checker tool (SFC.exe) scans for missing or corrupted system files and repairs them.
