How to disable password complexity via command

Question

hello
i have spent hours searching to find a command or script (powershell, cmd, VB, registry...) to disable group policy password complexity. few solutions has been delivered on the net but none of them works.
i wonder how what a pity if we can't do such simple thing in Microsoft windows
i really need that because i have created a script which contains many lines which automates windows customization which i always need in my classrooms for testing & teaching purposes
thanks in advanced

The answer is in your question: group policy password complexity. http://technet.microsoft.com/en-us/library/cc875814.aspx#ECAA 
On a non-domain joined pc, this is governed by local policy.
Note that if your domain is on functional level 2008 or up, you can use fine grained password policies to have a different password policy on the systems your are deploying. http://technet.microsoft.com/en-us/library/cc770394(v=ws.10).aspx
There
is no (supported) way to change the password policy applied to a computer. That is intended in the design because password complexity is one of the keys to protect against bruteforce attacks.
Why wouldn't your script be able to handle password complexity rules? I would recommend tackling this in
your script, not in password policy.

hi SenneVL
i don't understand your sentence:  "Why wouldn't your script be able to handle
password complexity rules? I would recommend tackling this in your script, not in password policy."
i exactly need a way to disable password complexity via an script. what script can do that
?  as far as i searched, no script
