Installing a `.crt` file as a Trusted Root Certificate in Windows 11 while Kleopatra is installed

I was recently setting up a project which requires the installation of a .crt file as a Trusted Root Certificate for the Current User. The standard way of doing this is to right-click the file and select “Install Certificate”. However, I have Kleopatra installed, and this removes the “Install Certificate” option from the context menu.

The workaround I found was as follows:

1. Search the start menu for “Manage User Certificates” and select the option with that name.

2. Expand the “Trusted Root Certification Authorities” folder.

3. Right-click “Certificates”, hover over “All Tasks” then click “Import”.

This opens a wizard which I followed to install the .crt file.

According to Claude (so I have no idea if this is true or not 😅):

Kleopatra associates .crt files with GnuPG operations, which removes the "Install Certificate" context menu option.
