How to script a global bandwidth limiter in Windows7

Hello,
I just came across a post here: "Socket-based HTTP Client with Bandwidth Limit" so hope that there is sufficient knowledge to help.

I have been crawling the internet searching for a windows7 command line application which will allow me to set the global bandwidth limit of a network adapter in Windows7.

For example:
> bwlimiter -u 50kb -d 200kb
(to simply change the global upload bw to 50kb and the download bw to 200kb,.. or whatever I specify).

Any suggestions on how I can do this?
Really appreciate the help if one can advise.
