ZAP is finally available via the Windows Package Manager (Microsoft's free and open-source package manager) over 3 years since we first submitted it!
If you have winget installed you should be able to install ZAP using
winget install --id=ZAP.ZAP -e
It still says "OWASP" as this is ZAP 2.13 and the package name has to match the name used by the executable.
If you use Windows then please give it a try and let us know how you get on!
Many thanks,
Simon
