Automatic driver search & update on Windows? [closed]

I have a Dell laptop issued by my employer, and I always find it a real pain to search for, download and maintain their drivers. It baffles me that there does not seem to be a nice way (product, website, ...) to just download the stuff you need, without hassle. The same goes for the other Windows based laptops in my direct environment.

Are there any (preferably free) automated solutions available? Or do you have a nice workflow - other than searching the manufacturers website - to help smoothing this process?

Drivermax is free and the best and supports Windows XP, Windows Vista, Windows 7/8, 64 and 32-bit.

Update Notifier is one of my favorite FREEWARE programs. However, Driver Checker is also a good one.
