Answer 1

Kalle posted a link to a page that has this video on it, but it's done on XP. If you use Windows 7:

1. Press the windows key.
2. Type "system env". Press enter.
3. Press alt + n
4. Press alt + e
5. Press right, and then ; (that's a semicolon)
6. Without adding a space, type this at the end: C:\Python27
7. Hit enter twice. Hit esc.
8. Use windows key + r to bring up the run dialog. Type in python and press enter.
