The Japanese MS-IME that came with Windows 10 got sick and I reinstalled it.

[procedure]

Remove Japanese MS-IME
Add Japanese MS-IME
End of procedure

When performing Step 1, I added English (United States) because Windows 10 must have multiple language packs installed.

Right after that,

A "J" icon now appears next to the input indicator in the notification area.

The "J" icon provides an interface for switching the input language, so I think it is a useful icon for those who intentionally have multiple language packs installed.

However,

I just want to hide the "J" icon if possible because I'm annoying to remove English (United States) and just leave it alone.

To remove the "J" icon...

When I checked,

I've found two pieces of information that may remove the "J" icon from the Windows 10 taskbar.

[information]

Delete Language Pack English (United States)
Remove LayerDriver KOR in the registry

"Information A" was effective in my environment.
"Information B" had no effect.

Input indicator: off

When the input indicator is turned off, the "J" icon disappears, but the IME display on the left (the "A" icon in the image at the beginning) also disappears, which makes usability worse.

[procedure]

Launch the settings app
Select "Personalize"
Select "Taskbar" from the menu
Click "Turn system icon on/off"
Turn off the input indicator
The "J" icon disappears from the notification area
End of procedure

Snapshot

Settings app> Personal settings> Taskbar: "Turn system icon on/off"

Click to toggle between On | Off.

English (United States) deleted

Info A: Remove English (United States)

In environments where multiple language packs are installed on Windows 10, a "J" icon is displayed in the notification area.

Therefore,

The problem can be solved by using only the Japanese pack.

Delete LayerDriver KOR

Info B: Remove LayerDriver KOR in Registry

It didn't work in my environment, but I found that I could fix the problem that "106/109 Japanese keyboard" was falsely detected as "101/102 English keyboard", so I'll write it down in a note.

Use Registry Editor.

Afterword

Suitable value for keyboard

I found the parameter information on the Microsoft official website, so I reprint it.

The registry value of "106/109 Japanese USB keyboard" is as follows.

106/109 Japanese USB keyboard
Value name	Value type	Value data
LayerDriver JPN	REG_SZ	kbd106.dll
OverrideKeyboardIdentifier	REG_SZ	PCAT_106KEY
OverrideKeyboardSubtype	DWORD	2
OverrideKeyboardType	DWORD	7

If the keyboard is detected incorrectly, check the set value.

You should delete "Layer Driver KOR".
