Now open Device Manager and let’s see what we have, you will notice that Windows 7 installed driver for your Sound Device, Modem and Wireless Network Adapter. But you still have 2 yellow icons named “Ethernet Controller” and “Unknown Device”.
As you expect “Ethernet Controller” is your Network Adapter but don’t worry because Windows 7 can recognize it! All you need is right click on it and choose “Update Driver” option and tell Windows that you will install the driver manually then choose Vendor “Intel” and device that named “Intel PRO/100 Network Controller” (or what ever your network card is) and let Windows install the driver for you.
Now what about “Unknown Device”? after some search I found it, it is HP Quick Launch Buttons. You can now check that your launch buttons is working fine except that you see nothing when you use them (you are not seeing any thing when you darken or brighten your screen for example). So you need to install a driver only if you want to see something when you use your launch buttons, I found a lot of drivers for HP Quick Launch Buttons on the internet but no one works with Windows 7 (64 bit). Finally I found this one which worked perfectly.
You still have one drive that could be better, yes it is Display Driver. All you need is going to “Windows Update” from “Control Panel” and let Windows check for updates, you will see about 4 updates related to your drivers and one of them will install a Nvidia Driver for you (about 16 MB). DO NOT INSTALL the update related to the modem driver, because after I installed it I got a blue screen every time I connect to the Internet with a dial up connection until I uninstalled that update.
So you are now using Windows 7 and you manually downloaded only one driver (Even though you don’t really need it!).
