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;
