Windows 7: 2 system locale?

Is there any Multi-Language system locale?
Can i have 2 system locale the same time?
For example english and russian.
I want this because when i use something in russian its look gibberish and is fixed only when i change the system locale in russian and restart the pc.
But then some other things in other language look gibberish.
So..can i have 2 or more system locale at the same time?
---------------------------------------------------------------------
Btw.Is there any other solution that can show letters/symbols russian as russian,english as english,japanese as japanese etc without changing system locale?

Hello?
Anyone?

Hi panais,

not sure what exactly do you mean.

If you are trying to install software in different languages at the same time, then most likely you will always have a problem. If, for example the installer only speaks one language and your OS speaks another you will always have unreadable messages popping up.

If, on the other hand, you simply want to read a document or a website in another language then it works fine and you do not need to do anything. You might see Firefox showing question marks in its title bar, but that's as much trouble as you will see.
