Calling this a "project" is overkill but I figure it might be useful to others as it's something I've wanted to use very often myself:

https://github.com/jakemason/PATH-Adder

Essentially, this PowerShell script makes adding all of the folders inside the working directory to your $PATH on Windows' quick and effortless. This has been very useful if you install all of your tooling under the same directory such as C:\tools. Probably a small use case but if you're like me and set up new machines frequently, this is much faster than doing it via the Windows GUI.

This is also really useful for quickly adding https://github.com/ibraheemdev/modern-unix items to your PATH quickly. 🙂
