I would set those DVD's aside to use only if you need to ship the machine back for warranty service, or restore to factory condition to sell it.
A better restore is to wait until you have your Windows 7 setup the way you want it: factory bloatware uninstalled using Revo Uninstaller, all startup freeloaders turned off in msconfig>Startup except AV and gadgets, a lightweight effective free AV like MS Security essentials installed, then the HD cleaned and ordered perfectly with CCleaner and Auslogics Defraggers.
When it is exactly as you like, save externally a Windows 7 backup image which can reimage the HD or a replacement in 15 minutes to exactly like you want it - not like the factory shipped it.
Most tech enthusiasts even find a clean-copy DVD of their Windows 7 version to clean reinstall after wiping the HD, activating with the Product Key on COA sticker on the computer. Let us know when if you want to do this later and we can advise you more fully.
