Windows 10: Keyboard Trouble with multiple laptops

Laptops are HP Spectres.
Running into the same problem with most of them.

Keyboards are typing erratically, example follows.

Intended message...
This is a test message

What comes through...
Thiiiiiiiiiiiiiiis is a ttttttst meeeeeeeeessae

This is happening through USB wireless adapters, bluetooth, and wired. Also some go through docking stations.
Built in keyboards seem to work fine.

Same issue happens with a factory reset laptop I tested bluetooth on.

Issue is consistent on the Windows 10 machines only, but doesn't actually happen 100% of the time.

Any ideas?

Toshiba Satellite S50-C keyboard not working properly after Windows 10 Creators Update

Finally, I have a resolution.

I had even tried a different operating system, and thought for a while the problem was fixed--but it came back.

Finally I broke down and replaced the keyboard. For anyone who has a similar model of laptop, be warned; you have to get to the keyboard from the bottom up, essentially disassembling the entire laptop to its individual components before you can replace the
laptop and put it all back together again. Not for the faint of heart.

But so far I have not had any trouble!

I have no idea why a hardware problem would have appeared and disappeared in line with software changes or reboots, and why multiple keys would work or not work at the same time, or why multiple keys would be finicky, instead of working perfectly or not
working at all...

But at least the problem is fixed!

 

Attaching keyboard causes help & support to pop up.

It is a wired USB keyboard which causes all these trouble. The default keyboard equipped with the laptop does not feature this problem.

 

There are some on the HP forum. Seems HP keyboards have been prone to this for some time, this from 2013 suggests modifying the Ease of Access settings, should equally well apply to W10.

Also forgot to mention, there is also a lot of input lag with the keyboards when this is an issue.
You can have your hands off the keyboard for 3-5 seconds and it will still be spamming letters or trying to catch up with what you typed. This includes wired connections...*Confused

 

This stopped the repeating keys on the machine I'm testing, but I'm still getting terrible lag and dropped inputs.

 

Maybe some HP bloatware loaded at startup, try disabling some of it as suggested here...

No noticeable change as far as I can tell.
Tried turning off everything just in case.
Rebooted 3 times with all startup options disabled without any luck.

 

OK, have a look at this...

...again, equally applicable to W10.

 

Filter keys was off. Turned it on and back off just in case.
No noticeable change in behavior.
Tested different levels on repeat and delay options.
No noticeable change in behavior.
Thank you for your multiple suggestions so far, I appreciate the help.

 

I'm afraid I'm out of suggestions now *Sad filter keys is HP's only suggested cause in their trouble shooting guide...

You may find updating the driver may help, as suggested a bit further down under 'function keys do not work'.
