Hello,
I use winget on a Windows PC to update software and libraries (C++ for examples) with the command line. Just as I would do on linux with a package manager.
Not all software are supported but LibreCAD is supported. This means you can check if an update is available with one command : winget list --upgrade-available. You can compare the current version and the available version on winget repository and decide to upgrade or not.

In order to upgrade: you need to copy (CTRL+C) LibreCAD.LibreCAD in the ID column and paste it (CTRL+V) to get the command: winget upgrade LibreCAD.LibreCAD
You may need administrator’s password to upgrade the software. Voilà !
