Can't change language in Windows 8

Question

I have some trouble with languages in my Windows 8.1. I can't tell when it happened (what could i do in this time), but right after installing os and maybe a few week after it was okay. But not now.

So, my problem is:
I use two language Russian and English (US) (US by default). And after rebooting computer I saw that it's no lang button on the taskbar (next to tray), and It's Russian now and I can't change language (I tried a few different cases). I remove Russian one in list via control panel, and nothing happen (absolutely!). I tried to add some different languages and remove them - nothing!

After all, I remove all languages except English and reboot computer again. After that I saw a normal behavior and English by default (it's no lang button next to tray, but it's normal because it's only one language in system). I tried to add Russian one. It worked, russian was added successfully, I saw lang button and I can change keyboard language with keys combination. BUT it's not happy end. I remove Russian one again, and saw it:
I have only one language in list, but it's two of them in system! And I can change language and use them by normal (before rebooting).
And one more thing: when I have 2 languages before rebooting, then after it I have Russian one by default and it blocked (I can't change anything, I have to reboot). So the same thing as in beginning of story.

By the truth, I have another windows 8.1 on my laptop and I haven't seen the same behavior. It's the same combination of soft I installed. I install a lot of systems (start with windows 98) and I never have seen this problem.

After googling, I see that maybe it's a problem with my register. Maybe something can block it, so I have this behavior. But I don't what is it...

Any ideas?

P.S. Please, don't tell me use one language, or remove russian one before reboot, and add it after (I do this now:). It isn't the solution of my problem.

Solution

I still don't know what the problem was, but now after updating system (I didn't note which one helps) this problem disappeared. Everything is back to usual work. Magic.
