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".

Change your Windows display language
To change your Windows display language (that's the language you see most often in Windows and apps), first add a language, download and install the language pack, and then follow these steps.

Prevent language from automatically being changed

• Since Keyla has stopped working.
• Two.
• When I test if the language stays after switching between programs - I switch to a different program, then switch the language, then switch to the previous program.

The steps you suggested didn't work, as I don't want to remove any of the languages.
