Every time when we try to install any hardware drivers which are not signed by microsoft, Windows shows a warning of Unsigned driver dialog box. The reason of showing warning message is to protect the stability of your Windows operating system as such drivers are not passed in Microsoft windows driver compatibility test.
In Window XP you can still install unsigned drivers but in Windows Vista SP 1 and Windows 7 Microsoft has introduced very restricted module of driver signature enforcement which doesn’t allow us to install any incompatible unsigned drivers.
If you want to bypass or disable Unsigned Driver warning message then Here is small freeware utility Driver Signature Enforcement Overrider which allows you to install and load unsigned drivers dynamically on your Windows 7 and Vista.

Very good. Old article now, but still good and up to date. I am going to use it. But I’d like to add that many unsigned drivers do not make Windows unstable and are not signed because the manufacturer of the hardware frequently publishes new drivers and does not want to pay Micro$oft for their approval. It would be a permanent income rent for Micro$oft. Such is the case of Realtech, ATI, AMD or Asus among many other reputable manufacturers, for example.
