What's the limit for characters in Windows passwords?

I came across this interesting comic which explains in a roundabout way that choosing a passphrase is more secure than choosing a password.



Does anyone know the limitation for characters in Windows password settings? I know there's a policy in Server 2008 that forces 8 characters, and you must choose 3 of the following: upper case letters, lower case letters, numbers, and symbols. Is it possible to use passphrases with Windows 7 or Windows XP?



Since Windows 2000 and Windows XP, passwords can be up to 127 characters in length, plenty for you to type a small passphrase, an easily-remembered sentence.


However, wifi passwords with the best encryption (WP2 enterprise) are still limited to 30 characters. And a lot of websites are limited to even fewer.
