Возник такой же вопрос, нашел такой ответ:
1. Add the Sublime directory to the windows PATH
2. I think 'subl' is a Mac-only command. For Windows it's 'sublime_text'
To add Sublime to the PATH:
1. Right click Computer -> Properties -> Advanced System Settings -> Environment Variable
2. Under 'System Variables' select variable: Path and hit 'Edit'.
3. At the end of the 'Variable value' text field, add a semicolon and enter the Sublime Text directory (for me it was 'C:\Sublime Text 2\' but the default is C:\Program Files\Sublime Text 2\)
4. OK, OK, OK
and then just rename the sublime_text.exe to subl.exe and you will be ready to go
