I'm working on English (UK) version of Windows 7, my second input language is Russian. Since installation of Windows I have removed US keyboard layout and set LEFT ALT+SHIFT as input switcher.

Everything was fine until now. Recently I noticed that my switch combination does not always work. I opened language select bar and found there English (US) keyboard layout. I went to settings and found that in General Tab there is only two languages available, US was not listed. I decided to add US layout manually and remove it after. This operation went as expected, US layout disappeared from language bar. But after few hours it appeared again.

I started "googling" and found that I'm not alone. On Microsoft forum I found suggestion to remove US layout as I did before and than copy all settings to all profiles.

It's look like some service are adding US layout on it's own, but I have no idea which one.

Does any one know how to fix this issue?
