Here is one resource: http://www.cyrillic.com/russian.html

and another couple:

From what they say, it requires some of the texas two step approach to install and enable cryllic on a western keyboard based system. But MS Word does have a downloadable multilanguage support package.

That package does include a form of cryllic. There are also other packages for sale which also enable that.

Good luck!
