From PCMag.com:
Odds are your PC came with a recovery disc, a CD with all the programs and drivers that were installed on its hard drive when it was new. The odds are also that you have absolutely no idea where that disc is.
The good news is that it probably doesn’t matter. First, the recovery discs provided by most PC manufacturers are designed for a single purpose: to restore your computer to the state it was in when you bought it. This process typically involves wiping your hard drive clean and then reinstalling Microsoft Windows and the handful of programs originally included with your PC. Unless you’re preparing the whole kit and caboodle to sell on eBay, this is probably not something you’ll ever need.
Second, the hardware drivers on your recovery CD are probably out of date, either made obsolete by newer and better versions available online, or simply irrelevant because of new hardware you’ve installed.
So, instead of fretting about the old recovery CD, why not take a few minutes and make one of your own?
