This usually occurs if you've used Russian language based Windows 11 ISO file or installation media. Adding and removing the undesired language is only way I know about this problem. To fix it permanently, try installing Windows 11 with media of language you want.
Language adding in Windows 11 automatically
Hi everyone.
I have Windows 11 and using 2 languages - English and Ukrainian. From some point I found that Russian language appeared in list.
But when I opens keyboard settings, there are only 2 languages that I am using
I can delete Russian by adding it here and deleting. But after some time it appears again.
I never had installed Russian on this PC and never installed any software that using Russian. I want to find, what is adding it in Windows automatically and delete it totally. Anyone knows how to find the root of this issue?
