How do I get "crypto shell extensions" back in to open with in windows 11?

I have installed openpgp and kleopatra. After installing it, most of the certificate file extensions like .p7s, .pem are opening with it. How do I change it back to crypto shell extensions?

I want it like this. You can see, it is showing Crypto Shell Extenstions

Examine the (Default) registry value for: HKCR\P7SFile\shell\open\command

It can be changed back to:

%SystemRoot%\system32\rundll32.exe cryptext.dll,CryptExtOpenPKCS7 %1

Note: P7SFile is the (Default) value for the HKCR\.p7s file extension.

If necessary, repeat the steps above for any other 'stolen' file extensions.
