PowerShell scripts that fetches the latest portable version of HWiNFO (stable or beta, whichever's newer) from SourceForge or HWiNFO.com, extracts the 64-bit exe into the current working directory (overwriting any that may already be there), and then deletes the zip-file again.
So you don't have to do all of that yourself.
It doesn't really handle failures gracefully. Maybe that'll come later.
