Try opening a specific function
.Cpl files opened by Control Panel refer to specific functions such as Firewall and Network Adapters. If the Dashboard home page is not opening, you can try performing the functions separately.
Step 1. Open Windows Explorer. Type the path "% SystemRoot% System32" (without quotation marks) in the address bar and hit Enter;

Step 3. If the files do not open, try to access one of the functions manually from the Run feature: type the command Windows + R and type appwiz.cpl (without quotes) in the window to open the program uninstaller. If it opens, you can explore further options using the built-in menus.
