It does not have to be manually downloaded!

An update can be performed using winget. One of the things I routinely do after a Windows update is run these two commands from a Windows command line:
1. winget upgrade
2. winget upgrade --all
The first shows any app that have updates, and the second initiates and performs the upgrade. 7-Zip was one of the recent ones. There are other winget commands such as selecting what specific app to upgrade, and many more.

This is a lot safer that getting the download from some untrusted source.
