In the video, you can see the dots on the small white WhatPulse icon being the second from the left in the notification area of the taskbar. Each dot on the right side of that icon is a keypress, I am typing in the video even though it doesn't show anything in the Terminal.

I also used Terminal just last week and it was fine, looking at it on the Windows Store it looks like it auto-updated over the weekend to the version listed above. I think the issue was probably introduced in that version.

I checked #4448 as well, I do have the "Touch Keyboard and Handwriting Panel Service" running.

(the following is copy-pasta, so yes I see that you've got the "Touch Keyboard and Handwriting Panel" started)

Can you confirm that the "Touch Keyboard and Handwriting Panel" service is running? You can check that with the command

sc query TabletInputService

Which should get you something like:
image

If you're seeing that the service is running, could you check if ctfmon.exe is also running? Apparently ctfmon.exe is the real important process, which the service is just used to resurrect.

> tasklist /v /fi "imagename eq ctfmon.exe" /fo list

Image Name:   ctfmon.exe
PID:          10828
Session Name: Console
Session#:     1
Mem Usage:    26,536 K
Status:       Running
User Name:    REDMOND\migrie
CPU Time:     0:01:05
Window Title: N/A

image

It needs to be running with a stable PID. So run that command a few times and make sure that the PID isn't changing.

Also, can you check InputServiceEnabled in the registry? You can do that with:

reg query hklm\software\microsoft\input /v InputServiceEnabled

Which should give you something like:

HKEY_LOCAL_MACHINE\software\microsoft\input
InputServiceEnabled REG_DWORD 0x1

(See #8045, #4448)

Here are the outputs from those commands:

It looks like ctfmon.exe is not running for some reason, strange. I tried to start it, but it looks like it might be closing or crashing right after launch.

@ebadger can you help OP here figure out why ctfmon.exe is crashing on launch?

Could you try following these instructions:
https://docs.microsoft.com/en-us/windows/win32/wer/collecting-user-mode-dumps

and enable collecting user mode dumps to your local disk?

Do you see any ctfmon dumps? If so, I'd like to see one of them.

Thanks,

Eric

Hey @ebadger I enabled the dumps in my registry, but running ctfmon.exe doesn't seem to produce any.
The %LOCALAPPDATA%\CrashDumps folder is empty after running these commands:

Would you run this command and reply with output:
tasklist /m msctfmonitor.dll
