Silab's driver for CP210x USB adapter can't install after Win10's latest 1803 update. Here's a workaround until they update the driver: https://www.silabs.com/community/interface/forum.topic.html/cp210x_driver_v101-91Gl
This only affects new driver installations after the 1803 upgrade. If you installed the device prior to the upgrade, you're fine.
This worked fine on a PC I just got for my office. Check out the smoking deal ($50 offer, shipped) on this monstrous refurb desktop beast with Win10 Pro: https://www.ebay.com/itm/282951085982
Good enough for most everything but gaming.
"When you make a thing, a thing that is new, it is so complicated making it that it is bound to be ugly. But those that make it after you, they don’t have to worry about making it. And they can make it pretty, and so everybody can like it when others make it after you."
