How to Install Windows XP Without Formatting

      There are different reasons why a reinstall is required. Some of the most common ones are missing .dll files or too many virus or spyware attacks detected. Or it could be the desire for a seemingly new operating system (OS). After years of removing and adding programs and files, your system is scarred by the residual files. The easiest way to reinstall Windows XP without formatting your hard drive is by choosing the "repair install option." This installs XP to pre-SP2 (Service Pack 2). Service Pack is Microsoft's security upgrades and bug-fixing feature.


Instructions


Things you'll need
 Windows XP CD (either store-bought or original from computer manufacturer) Printed instructions


The basic Re-Installing


1.Insert the Windows XP CD into your computer, disconnect your computer from the Internet, and reboot (or restart) your computer.

2. Your computer should automatically direct you to a screen with options for reinstallation. Do not click on the option that mentions "recovery console." Click the option for "installing Windows."


3.Accept the agreement, and on the next page you will choose an install option. Press "R" for repair, and continue.


4.Follow the on-screen instructions till you're done. At the end of the process, all your previous settings, files and programs will remain untouched, and your system will run without qualms.


5.Don't forget to immediately update your computer by downloading SP2 from Microsoft's website download link

6.  You can wait until Automatic Updates detects SP2 is missing, but it is not recommended.


Tips and Warning!


     If this doesn't work, search for methods using partitions. A system with too many vulnerabilities should go straight to a format and clean installation of XP.

      Don't forget to disconnect from the Internet; your computer is most vulnerable during the install process if connected.
