Bit off-topic, but I was sorting out a laptop for a friend, it's a couple of years old with Windows 11 Home. They could not add another language, switch from Thai to English.
Did a bit of searching, this edition of Windows 11 Home could not have an additional language....????
So be careful what you buy.
Anyhoooo, I installed Windows 11 Pro, then activated it...????
Now has any language they want, plus other stuff...????
