I have two computers. One a fairly recent machine I call Corsair based
on an Asus X00-AII with an i7-6800K CPU and the other being a nearly
10 year old Dell XPS something or other an i2-2600. Both are running
Windows 10 Pro with the 1903 update. Both are equipped with Logitech
USB keyboard and mouse, although not the same model. The DEll has very
recently experienced a change of keyboard and mouse.

Since the update both machines have experienced keyboard problems but
Corsair has recently lost its mouse unti after a repair install and a
reboot.

The problem with Dell is that it does not respond to text entry until
some time after the machine has started. This makes password entry
(and hence logging on) difficult. At first you can type anything you
like and get absolutely no response. After two or three minutes you
will get a response but the first two or three characters are missing
and I have to start again. I have to watch the screen like a hawk to
ensure that the machine responds to each keystroke. After some time
the machine appears to respond normally.

I have not encountered this problem if I boot in safe mode. This seems
to suggest that with a normal boot one or more of the lesser services
are tripping over something and preventing Dell from detecting the
keystrokes. However whatever it is does not seem to interfere with the
screen cursor's response to the mouse.

I could go through deleting one service at a time and then trying
rebooting to see if that solves the problem. Howevere I have only a
few more years to live and I would be grateful for any suggestions
that might speed up the testing process.

The other problem manifests itself mainly on Corsair although Dell
occasionally suffers from it also. What happens is that I will be
happily typing away and I will suddenly realise that without any
warning characters have stopped appearing on the screen in response.
All I have to do is select the starting point with the cursor,
left-click, and start typing.

All that makes me think that the two types of problems might be
connected is that the both started after 1903, both involve keyboards
and mice, both keyboards and mouse are of the same make (although not
the same model) and there could be a common factor which has arrived
with 1903.
