Updating Windows Basecamp

I looked at Garmin website for this but it appears to be a be different in Windows  (whereas Mac seems to read it updated automatically or from it's menu)

I'm running an existing install of Basecamp on Windows 10. Does my Basecamp update through the Garmin Express app or do I have to download and run the latest Basecampxxx.exe install?

If it's the download install, will it install over an existing Basecamp and does it preserve any of my menu settings etc?

Appreciate any input on this.
