I need a tethering app without client

hi guys, I have been looking for a USB tethering app so to, use internet through my android phone`s data package. I have a droid razor by Motorola and whenever i tried to start USB tethering they ask for subscription ( however it works without any limitation in other phones)

I know there are various third party apps, but I can install their client programs in my windows based computer at work. Therefore, am looking for such an app that works without a necessity of client`s installation in host machine. Please suggest me if you know about such an application.

In short, I need an application that can eliminate the restriction of USB tethering in Motorola droid phones

you can post on fiverr to get that
