The standard way to delete the certificate would be to check the installed certificates using the command certmgr.msc and delete it from the list.
Press Windows Key + R Key together, type certmgr.msc, and hit enter. You will get a new window with the list of Certificates installed on your computer. Locate the certificate you want to delete and then click on the Action button then, click on Delete.
You can also find the actual registry entries under:
In HKEY_CURRENT_USERfor user-specific certificates and KEY_LOCAL_MACHINEfor machine-specific certificates,
