I can't download japanese keyboard

Hi JC,

I’m following up to see whether the previous steps helped or if you’re still seeing error 0x800F0806.

When you have a moment, could you please check a few details?

• Are regular Windows updates downloading and installing normally?
• Press Windows + R, type winver and share the Windows version and OS build shown.
• Is this your personal computer or is it managed by a workplace or school?
• Under Settings > System > About, does the Windows edition say Windows 11 Home Single Language?

If the error is still there, you could also try repairing the Windows system files. Open Command Prompt as administrator, then run these commands one at a time:

DISM.exe /Online /Cleanup-Image /RestoreHealth
sfc /scannow

Please let each command finish fully, then restart the computer and try adding Japanese again from Settings > Time & language > Language & region.

Feel free to skip anything you’ve already tried. When you reply, please include the results of both commands and the Windows details above, I’ll be happy to help with the next step.
