I do this all the time for people. Skip the recover CD entirely. Most of that will reload all of the crap that came with it. Instead, look for the Windows product key label on your computer. For instance, if it says "Windows Vista Home Premium OEM", download a torrent of the .iso and burn it. This is PERFECTLY legal since you have a license key. Then, use a piece of software like double driver and extract the drivers on your current setup to a flash drive. Wipe the drive and install the fresh copy of windows you downloaded. When prompted, enter the product key. When installation is finished, restore your drivers. Then install Microsoft security essentials, run updates and install very light software and disable most startup items. Most computers I do this to boot up in 15 seconds or less. If you would not like to do any of that, PC Decrapifier is a great piece of software to use and will guide you in uninstalling the garbage that comes with it.
