Most manufacturers that have a restore partition on your hard drive instruct you to make a set of disks for emergency restore for the eventuality of a hard drive crash.
Look up restore at support for the make and model of the computer you have, or alternatively you can contact support at the manufacturer to buy a set of restore disks made for your specific model.
Make sure you have the Microsoft 25 digit key number and store it in a safe place where it won't become lost. It should be on a sticker on the outside case of the computer. You will also need the serial number and model number of your computer if you need to contact the manufacturer. Support at the manufacturer's site will show you how to find these.
If you can't find the MS Key number on the computer, download keyfinder v1.41 from magicaljellybean.com which will give you the key number of your Microsoft Windows installation. Keep it in a safe place, as even if you do not need it ow, eventually you will.
