Here are the windows updates. Hope it helps. Thanks .

[Walt-White]

I have two computers with two very different behaviors. The easiest to describe is my desktop:
Lenovo Razor ideacentre Y900 RE-341SZ Signature Edition
Windows 10 Home version 2004 build 19041.508
Chrome browser Version 85.0.4183.121 (Official Build) (64-bit)

When I go to code.pybricks.com and hit Refresh to be sure I have the latest firmware, and try to download to my City Hub, I get the message "No compatible devices found."

I've tried to pair the City Hub outside of Pybricks by just using the Windows "Add Bluetooth Device" utility, and the City Hub is never seen. So it's like my internal Bluetooth radio isn't compatible with the City Hub. When I look at Bluetooth in Device Manager, there are a lot of things listed and I can't tell which of them is the internal Bluetooth radio.

I'll list my laptop behavior in #136 because it's similar to things discussed there.
