How to remove registry key

I removed comodo firewall with ciscleanuptool_x64.exe. Now this tool says that installation of Comodo product not detected. But I see this key in registry
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\Provider\Fw{3D9428CB-50D2-A37E-F90F-1D238F042427}


How can I remove it?

this is a registry entry “windows security center”;
you can remove, but it is not necessary :-TU

If you can’t delete it manually then try using Registry DeleteEx.
