Installation

1. Install Google IME for your chosen language: http://www.google.com/ime/transliteration/
2. Download any of the available transliteration schemes.
3. Copy your chosen scheme file to Google IME Scheme's directory: Google IME Canonical Scheme. The directory mentioned on the previous link is wrong (as of 5/2013). The correct directory for {language} is: C:\ProgramData\Google\Google Input Tools\com.google.input_tools.t13n.ime.{language}\schemes\. ProgramData is usually a hidden directory under C:\.
4. From Window's language bar select your language, in Google IME select your chosen scheme (Ctrl-M).
5. You can now start typing according to your chosen scheme into any Unicode aware application.

Caveats

Almost all North Indian languages are not Pheonetic for example, करके is read कर्के i.e. the अ of र is dropped while in भारत the अ is retained for र. Additionally the final अ of words are dropped if they exist. These are contextual rules that Google IME does not provide a way of specifying. Hence these features are absent while using Google IME with these schemes for North Indian languages. However, Samskrita and Sound Indian languages work as expected.
