Many of the samples were inspired or originally appeared in Kenny's articles and courses on Pluralsight.
The samples in the repo compile with the latest, usually pre-release, version of the windows or windows-sys crate.
To find the samples for a particular release you can use a specific release tag. For example:
https://github.com/microsoft/windows-rs/tree/0.48.0/crates/samples
That will give you the samples that compile with version 0.48.0 of the windows and windows-sys crates.
