windows - Editing System Environment Variables is allowed only when opened through Control Panel

On Windows 10, if I open the Environment Variables window directly through Windows Search, I can't edit the System Variables (buttons are disabled):

However, opening it through Control Panel (Control Panel > System and Security > System > Advanced system settings > Environment Variables) enables editing:

Maybe related: I recently editted some registry keys related to Users.

I'd like to be able to edit System Variables either way.

Answer

The Start Menu item is specifically titled "Edit environment variables for your account", so that's what it lets you do. I suspect the difference is that it doesn't go through UAC, while the other Control Panel link does.

Use the Start Menu item "Edit the system environment variables" instead.
