HWInfo Gadget - How to get it to work?

Windows 8 and 10 don't have built-in Gadget support anymore. You will have to use some 3rd party Gadget extensions, or the HWiNFOMonitor, which is much more advanced.
old thread i know, but this comes up on search results so best to post here i figure

Martin, I downloaded hwinfomonitor, but thats a gadget too it appears? thoroughly confused, please advise
Yes, that's a gadget too and will require a 3rd party gadget support (i.e. 8GadgetPack).
