You may also want to try going into Device Manager and disabling the COM
port and then enabling it again. I have an add-on serial port card in
my computer and I have to disable and re-enable both ports every time I
reboot or they will not work.
As a side note, I have a friend who had major issues with his computer
after installing a Windows 10 update. He finally found out that if you
have Avast or AVG anti-virus software, it must be disabled before
running the update. Apparently it sees some of the update as malware
and will put the computer in an endless loop of reboots.

There's a way of preventing Windows from changing COM ports, but I
forget what it is. Perhaps someone else can help, or maybe Google is
your friend. :-)

Subject: [Elecraft] Windows 10 Update Breaks COM Port for K3 & P3
Utilities
With the latest Windows 10 update earlier this week, my K3S and P3 can
no longer communicate with my Windows 10 PC via the USB cables. I’ve
gone into Device Manager and right clicked on the COM12 device drive
and clicked “update driver” and that updated from a 2016 driver to a
2017 CM port driver, but neither connect the PC to my K3S or P3. Any
suggestions? Thank you.
