Zero, MSVC compiler
It is strongly recommended to install VS first and then Qt! In this way Qt Creator will automatically configure the MSVC path!
Visual Studio 2019 download address (no login required):

You can download any version, the key can be found online
After installation, just download MSVC and SDK, search for "msvc latest" and "windows 10 sdk", and download the latest version.
If your computer is Win10, download the Win10 SDK. If your computer is Win11, download the Win11 SDK. Don’t download the wrong one!
