[Elecraft] Windows 10 Update Breaks COM Port for K3 & P3 Utilities

[G4GNX]

Windows has probably changed the COM port. Check in the Device Manager, by 
unplugging the rig, then re-plugging to see which COM port re-appears.
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.
