The Windows 7 operating system has a practical tool included which allows you to create a system repair disk. With this emergency CD/DVD, you will be able to recover your system in the event of failure through the use of a range of provided tools. This will allow the use to repair their system or recover important data if a full reinstall if required.
To use this, open the start menu with the Windows key and enter the words “system repair disc” in the real time search field.
Now you just need to select burn from the drop down menu, insert a blank CD or DVD and start the creation process.
