Uninstalling old version

This may a pretty silly question, but what’s the best way to safely uninstall an older version without screwing up the new one? (Windows 10)

I installed 2.82 last night, and as hoped, it copied over my user prefs, addons, etc from 2.81. I tried using Revo Uninstaller to get rid of 2.81, but afterwards, it asked me to perform an “Advanced Uninstall” that would have removed the installation and user data folders for both versions, so I cancelled it. My computer now only shows one version of Blender installed (2.82), but I can still use 2.81 just fine. Can I just delete the installation folder and scripts+config folders for 2.81 manually, or is there a better way to do it?
