To repair Windows XP , a complete format is not always required. This process can be quite inconvenient as it may lead to loss of data. Through the CD installation too, you can repair Windows XP. This can be done when the PC is booted up with the CD installation. The operating system must be a licensed one as the Windows registration key i.e. the CD key, is a must to carry out the repair.
Repairing Windows XP using the installation CD
The installation CD for Windows XP allows you to repair Windows whenever there is file missing or some other corruption or malfunction. It is worth following these steps before resorting to reformatting your hard drive and wiping your saved data:
The first step is to boot the computer using the installation CD.
Press Enter to setup Windows and accept the license agreement
Select the XP installation you want to repair and then press R
You will be asked to press any key to boot to the CD
Do not press any key - Windows will boot automatically and start the installation
After installation, enter the CD key (Windows registration key) to finish the process
You can now remove the CD from the drive and reboot the computer to check if it has worked.
