Yay! The latest Win 10 update restored compatibility with my Unifying receiver, K360 wireless keyboard and my M570 wireless trackball mouse. A Win 10 update a couple of years ago prevented Win 10 from seeing this KB & mouse on some PCs. MS never acknowledged the problem and Logitech either wasn't able or didn't make the effort to issue a patch. There were some workarounds, but none that worked well or consistently. Every Windows update since then I've I've pulled the out to see if they would work, but there was no joy until yesterday. Having the wi-fi KB back is nice, but the real biggie is the trackball mouse. I love that model and never found another one that was as comfortable to use. I considered switching to Blutooth, but this mouse is wi-fi only, no BT.
