Windows 10: Firefox & Explorer.exe random freeze when switch Language Input

Hi...

Recently I just upgraded my Windows 8.1 x64 to Windows 10 x64
and I'm getting kinda very weird problem.

My Firefox and Explorer.exe randomly become 'Not Responding'
only after I switch the language input between English and Thai.

Need you guys advice.

Thank you so much

:)

 

Can't type in Asian character in windows 10

For some reason, I can't seem to input using Chinese Simplified or Japanese when I switch to them in software like Chrome, Firefox, even Notepad. But it works perfectly fine in all the Windows Metro Apps, and Office 2016.

When I'm on, for example Notepad, and I switch to Chinese, it does not even let me toggle between Chinese Pinyin, or alphabetical input.

I have tried removing the languages from Windows then reinstalling them, does not seem to help at all.

 

Random keyboard input languages switching is driving me crazy

Windows Key + I > Time & language > Region & Language, click Additional date, time & regional settings > Click change input methods > Advanced Settings

Under Override for default input methods, choose US(English) or appropriate language.

Reboot your computer

(Note, here you will also find Switching Input Methods under Advanced Settings > Change language Bar hot keys. Here you have hot keys for changing language which must have been pressed inadvertently. This hot key can be used to switch languages)
