Before reinstalling the Microsoft® Windows XP operating system to correct a problem, try correcting the problem by performing a Windows XP System Restore (see page 50). The reinstallation process can take 1 to 2 hours, and you will need to reinstall your drivers, virus protection program, and other software when the process is complete.
