For our current system, we'll be selecting the 64 bit version. First, we'll want to download the program HWiNFO32. The portable version has been already accepted and approved as "Portable" by sites like PortableApps, LiberKey, Portable Freeware. Description: How to check your system's hardware information and status from within Windows.

This will prevent HWiNFO from storing certain user settings (like screen position, user-defined sensor options, etc) in registry. REALiX accepts donations for the continued development of this free software. Download and installation of this PC software is free and is the latest version last time we checked. Moreover, if you don't want to leave any traces on machine after running HWiNFO32/64, then you should disable the "Remember Preferences" option too. HWiNFO is provided under a freeware license on Windows from hardware diagnostic software with no restrictions on usage. This behaviour can also be controlled via the "Persistent driver" setting in HWiNFO: portable version has this option disabled by default.

The installer version keeps this driver installed and inactive in system even when you exist HWiNFO.

So even the portable version installs this driver into system, but the difference is that the portable one removes this driver from system when you exit HWiNFO32/64. Without this driver it would not be possible to query 95% of information provided. Every version of HWiNFO32/64 requires a kernel driver (hwinfo32.sys or hwinfo64a.sys) in order to access hardware.
