Lenovo Service Bridge

[karotlopj]

I was installing Windows 7 on a ThinkPad T420 yesterday and as the installation finished I realised that many device drivers were missing, so I got hold of a network driver from Lenovo's website and downloaded it onto another computer aand installed it from a USB stick. Now I can directly retrieve drivers on the T420. I then downloaded the Lenovo Service Bridge program, which I thought could be used to download all the missing drivers... But I can't figure out how it works. If I click on it, it says that it is already running. But what is it doing, and how do I tell it to install all the missing drivers?

You need System Update.
