I get major delays in some scenarios using my keyboard and sometimes also mouse. Using (browser-like?) apps e.g. Windows start menu, Firefox, Chrome in Windows 10, it can take seconds or minutes for what I type to appear on screen (including this question!). Typing a lot of characters usually results in a few being displayed before a long delay, then all the remaining characters typed are spat out. Sometimes the problem is not apparent at startup, but almost inevitably develops at some point and then does not resolve without a reboot. Usually it does not affect performance in other programs e.g. Ms Word. This isn't a new issue.
I've recorded an example using Windows Performance Recorder https://www.dropbox.com/s/cr05fvvi0cp0q0s/TOMPC.03-21-2018.12-44-41.zip?dl=0
Having tried to look at the analysis and previously looking at task manager I've wondered whether Cortana is somehow involved. I tried disabling it through the registry but I think that's the communication with microsoft and anyway it didn't help.
System is:
Windows 10 Home 1709 16299.309
Intel i5-2500K
Asus PBZ77-V LX
USB wired keyboard (I've also used a different wireless keyboard)

1are you using wireless keyboard / mouse ? – Hongkie – 2018-03-21T13:58:40.513
Could be a hard disk failure. Check your hard drives for SMART errors How can I read my hard drive’s SMART status in Windows 7?, and What is the easiest method of checking SMART status for your hard drive?. Report back with the results.
– DavidPostill – 2018-03-21T13:59:26.080It's a hard-wired USB keyboard. – Tom Crocker – 2018-03-21T14:53:44.747
@DavidPostill Thanks. Both hard drives report ok health status. Details added to post. – Tom Crocker – 2018-03-21T15:08:40.297
Installed Windows Performance Analyzer. (You must first install WPA as a part of the ADK KIT, from https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install and choose which other 8 GB of other tools you want. The WPR - Performance Recorder itself, is also quite large). I got your 2 GB file -- and that is ONLY a 10 minutes recording?? Great exercise, but I didn't see anything obvious, but will need to become more familiar with the tool again, (since XP days). Any WPA experts out there?
– DaaBoss – 2018-03-21T17:01:46.240Thanks for looking @DaaBoss I may have selected more options in WPR than needed and maybe not others that would have been useful. – Tom Crocker – 2018-03-21T19:28:18.513
I think @Tom-Wijsman is a WPA expert https://superuser.com/a/205307/885974
– Tom Crocker – 2018-03-21T19:30:56.850if u have a ps2 port try you could try that ;-) (that was the solution to a slow usb keyboard back in the day) – barlop – 2018-03-22T00:07:50.977
Thanks @barlop I can't find my ps/2 adapter so I've ordered one. I don't think it's that as I don't have the problems in other applications but just in case. – Tom Crocker – 2018-03-22T12:37:33.243
@TomCrocker oh I don't think that be faster.. cos an adaptor goes through usb to your application, so whatever issue there is on that 'journey' would likely be inherited. – barlop – 2018-03-22T13:38:12.490
@barlop Not sure if you realise I mean a USB to ps2 (i.e. to plug USB keyboard into ps2 port on motherboard). Agree it's unlikely to fix it and don't even know if the ps2 port is essentially a ps2 to USB adapter (it's a shared mouse or keyboard port). Anyway, worth a try for £3 – Tom Crocker – 2018-03-22T18:51:48.563
@TomCrocker oh that's brilliant that you have ps2 ports. You could even try a ps2 keyboard. They are so responsive they even flash as soon as the computer turns on. – barlop – 2018-03-22T19:27:07.887
