Windows 10: Cant sign in because of keyboard language

My password in Arabic and keyboard doesn't switch to Arabic language.

:)

 

The extra keyboard layout keep adding to my language bar (with Pics)

Hi Panupong,

The updated Windows 10 may have detected your language, the reason why it automatically gave you the other Thai US keyboard. To correct this issue, we suggest that you follow these steps:

• Click on the Start Menu, type in region and language settings and select it.
• Under Languages, select Thai Kedmanee keyboard and click Remove.
• Lastly, add it back by clicking Add a language.

After these steps, your keyboard layout will permanently stay with Thai Kedmanee keyboard.

Let us know if the steps above resolved your issue.

 

Keyboard Layout

"Letters and numbers are all correct, but most of the other signs are misplaced"

This suggests to me that you are using the wrong "keyboard language" for your keyboard, and that therefore you first step would be to determine exactly what language keyboard you have. Possibly have a look at Windows Keyboard Layouts - Globalization | Microsoft Docs.

(The age of any laptop capable of running Windows 10 at all should not be a problem as regards keyboard layout)

 

Windows 8.1 update changed the language, can't change back

Maybe, these will help... it seems it is a common enough problem.

Language packs are no longer available after you upgrade to Windows 8.1

And, sort of the same here --> Add a language or keyboard

Quote from above MS web page:

Spoiler Download and install language packs
You'll need to download the language pack if you want to make a language your Windows display language (that's the language you see most often in Windows and apps).

• Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
  (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
• Tap or click Time and language, and then tap or click Region and language.
• Tap or click a language that says Language pack available underneath, and then tap or click Options.
• Tap or click Download. The download process might take a while, depending on your PC and the size of the language pack.
  If you want to make this your display language, see the next section "Change your Windows display language".
