Most Windows user should download and install the "installer.exe" build. It installs the program and puts a CHIRP shortcut in users Start menu. It can also be uninstalled by using the "Uninstall a program" feature in the Windows Control Panel.
More experienced Windows users can use the portable "win32.zip" build if they want. All they have to do is extract it to a convenient location. For example you could extract it to a USB thumb drive so you can plug it into your laptop or desktop computer. It is run by going to the folder that it was extracted to and double-clicking the "chirpwx.exe" file. You can also create a shortcut to this file and put it on your desktop if you wish. This is what I do to keep a copy of the final 20221227 build of CHIRP classic on my PC along with the latest version of CHIRP-next.
