Driver Magician:

Driver Magician offers a professional solution for device drivers backup, restoration, update and removal in Windows operating system. It identifies all the hardware in the system, extracts their associated drivers from the hard disk and backs them up to a location of your choice.

emsir your software is good and it is easily backup but its only trial version..any serial or crack..thanks in advance

okay here is a link for driver magician with crack. I have tested the megaupload link and it works...

thanks emsir iam going to upload..

emsir i want to ask one thing..how about windows live cd.?

With Windows Live CD you can boot into Operating System without installation into the computer. In short, Windows Live CD is a fully working operation system, it doesnt require installation.

from this also we can bacup everything right..and do u have any lin for this..? and many thans in advance..

You dont need a Live CD to backup everything. Use the built in backup or/and restore function in Windows or a third party program like Acronis True Image...And No, I do not have a link for Live CD

bcoz i have heard that from live cd we can easily backup our drivers thats why i have asked you and many thanks dude..

If you know what to do - why are you asking for help..??
