Try to open a specific function
The .cpl files opened by the Control Panel refer to specific functions such as «Firewall» and «Network adapters». If the Dashboard homepage is not opening, you can try to perform the functions separately.
Step 1. Open Windows Explorer. Type the path «% SystemRoot% System32» (without quotes) in the address bar and hit Enter;

Step 2. Use the Explorer search field to search for the term “* .cpl” (without quotes). When the results appear on the screen, open the files one by one to check if the Control Panel functions can be accessed – each file is a different resource;

Step 3. If the files do not open, try to access one of the functions manually using the “Run” feature: press the command Windows + R and type “appwiz.cpl” (without quotes) in the window to open the Program Uninstaller. If it opens, you can explore other options using the internal menus.
