Windows 10: Korean Keyboard Input Is Bugged Or Broken

When I first installed Windows 10, everything seemed to be fine but later on, I noticed one day, whenever I used the Korean keyboard, I kept typing random Korean letters and sometimes, even random alphabets. I really don't know what caused this problem because I didn't touch any settings about keyboards at all the cause might be the windows update not sure. I also realized that whenever I kept pressing the same key, I would keep typing different Korean letters.


Here is the result when I typed hello in korean:




And here is the result when I pressed the key "f" continuously:




I hope someone can help me fast with this problem

Difficulty with Korean and Japanese IME inputs

Apologies if this is under the wrong topic. Further apologies for the lengthiness of this question, this was the only way I could explain the entire issue. Let me know if further clarification is required.

I have recently purchased a Korean keyboard with Hangul written on each key, as well as a "한/영" (han/yeong) key. From what I can tell, the 한/영 key works
almost the same as the Right Alt key, in that it changes the Korean input between Hangul and Latin.

However, I've been experiencing some issues with my Japanese input method, and I believe using the 한/영 key is causing these issues. Below I've outlined two scenarios to try and describe my experiences. The error is only with the Japanese inputs.

Scenario 1:

• I use the Korean input method, and swap between Hangul and Latin inputs by pressing
  Right Alt.
• I press Left Alt + Shift to change from Korean to Japanese.
• If I type "nihongo" with the Hiragana input, it results with にほんご ("nihongo" in Hiragana).
• If I type "nihongo" with the Romaji input, it results with nihongo ("nihongo" in Romaji).

This is what I expect/prefer, and I was also attaining these results with my old keyboard.

Scenario 2:

• I use the Korean input method, and swap between Hangul and Latin inputs by pressing the 한/영 key.
• I press Left Alt + Shift to change from Korean to Japanese.
• If I type "nihongo" with the Hiragana input, it results with みにくらみきら ("minikuramikira" in Hiragana)
• If I type "nihongo" with the Romaji input, it results with ﾐﾆｸﾗﾐｷﾗ ("minikuramikira" in halfwidth Katakana).

This is not the result I want. I believe this result ("nihongo" -> "minikuramikira") is from a "Kana" keyboard layout, but as far as I can tell, my settings have not been changed from the Romaji keyboard layout.

After a reboot, I experience the results from Scenario 1, as long as I only use the Right Alt key to swap between Hangul/Latin.

However, once I use the 한/영 key, it somehow affects the Japanese input methods and I'm stuck with the results from Scenario 2 until I reboot my computer.

Besides avoiding using the 한/영 key, is there any way to resolve this issue? Otherwise, any other insight on what could be happening would also be appreciated.

 

Korean Input Not Working Properly

I installed the Korean IME input yesterday and I find my inputs aren't matching up with what the keyboard should be. For example, when I type a-ㅕs-냐 d-

ㄷ. I'm not sure what's going on but it's like my keys are bound twice in Korean input. For reference,
I'll include a Korean keyboard layout.

 

Korean keyboard on my pc.

You can find a Korean Keyboard @ All settings>Time & Language>under Related settings-Additional date, time, & regional settings>under Language-Change input methods>Options>Add an input method> Korean> It is not in Korean however, just a Korean keyboard
layout>preview and Add(at bottom)> you can then delete your other keyboard or select one for primary use.
