What should I do if the Win10 control panel won't open?

In order to adapt to the new Modern interface, Microsoft added the "Settings" application in Win8.1/Win10, but the settings in the traditional control panel have not been fully migrated to the new settings application. So the classic control panel is still preserved. For the old user, the control panel may be more convenient to use. But sometimes it may appear baffling problems open the control panel, in which case reference may be resolved following steps:

1, Win + R open press run, the transport path to enter the following:% SystemRoot% System32
2. Search for *.cpl in the System32 folder. Some small tools in the control panel will be displayed in the search results. Part of .cpl is added for third-party software, which adds its own entry in the control panel.

3, repair the damaged .cpl file.
Double-click each .cpl file separately, and if you can't open the control panel, these files are damaged. If the third party .cpl is damaged, just delete it. If the system comes with .cpl corruption, please use the following method to fix:
.cpl file corruption solution:
