CSR Bluetooth 'Caps Lock' OSD notification mute
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Cambridge Silicon Radio\Harmony\Default]
"OSD"=dword:00000000
From: https://answers.microsoft.com/en-us/windows/forum/windows_7-desktop/caps-lock-notification-appears-on-the-screen-when/285a5edf-eb03-4e19-93c3-63e869486180?page=12

I finally found the file in the registry that got rid of the notifications if you have a CSR Harmony Bluetooth dongle installed:
HKEY_LOCAL_MACHINE\SOFTWARE\Cambridge Silicon Radio\Harmony\Default
double click OSD
set value to 0
restart pc
no more caps lock on / off notifications for me!

PERMANENT FIX WILL WORK AFTER RE-BOOTING ENDING TASK ONLY FIXES UNTIL RE-BOOT
NO CODE EDITING JUST DELETE A FILE
I found a permanent fix thats better than ending the CSR OSD (on screen display) settings app. That program all it does is give that notification. So if its a pain, just ending task on "CSR OSD settings" is only a temp fix until you reboot. So I dug into it. CSR is silicon labs BT Driver, so if you have anything bluetooth, it has that driver and CSR OSD comes in the stackup. However I clicked properties on the CSR OSD task in task manager and found its associated .exe (vksts.exe.mui) in this directory address
C:\Program Files\CSR\CSR Harmony Wireless Software Stack\en-us
However you cant delete it while its running. So Ctrl + Alt + Delete -> Select CSR OSD Settings -> End Task.
Then go to
C:\Program Files\CSR\CSR Harmony Wireless Software Stack\en-us
And delete vksts.exe.mui and you have a permanent fix that wont change when you re-boot the system

Hope this helps someone as the microsoft answer doesnt work for me because everytime the update windows 10, they change the structure of the menu and a 14 month old guide wont have the options to click as described.

Awesome thank you and @ajdetroit420 for the fixes. Who in the world puts so many useless stuff into a Bluetooth Driver?

Thank you very much, changing registry key OSD to 0 helped me.

Thank you so much! This was making me tab out of video games and I spent ages trying to figure it out. At one point I was literally going through task manager and ending any task I thought might be the culprit. I noticed the CSR bluetooth software running and briefly considered it, but then I thought nah... there's no way they would do something so obnoxious as include a random caps lock indicator with no option to turn it off in a BLUETOOTH stack. Clearly I was wrong.
