My recommendation 1st You need to Update your Windows Operating System, 99% problem will be Solved with this. If the Windows 10 emoji panel used to work fine but suddenly it stopped showing up even if you press the keyboard shortcut keys, try to close every opened apps and restart your PC.
Even if you’re not sure if this has anything to do with the Windows 10 emoji panel shortcut not working issue, just try to change the keyboard language to en_US and see if it works.
Here’s how to add or switch your keyboard language to United States English.
1. If you have multiple keyboard input languages in Windows 10, click on the input method in taskbar.
2. Select English (United States) US keyboard. Windows 10 Emoji Panel not working change language
3. Try Win+. keys to open emoji panel and see if it works.
4. If you don’t see US keyboard in the input method list, go to Settings.
5. Select Time & language, then Region & language.
6. Click Add a language and add English (United States).add a language Windows 10
7. If that doesn’t work, try to also change the Country or region to United States.
After changing the keyboard language, you may need to restart your computer. Upon restarting your PC, try to press the Win + period (.) keys again and see the problem is fixed.
