Naturally all emergency planning should be done beforehand. Performing maintenance procedures on a regular basis allows you to prevent possible problems or at least minimize their negative effect. The general procedures are listed below Most of the time system malfunctions or even boot failures are caused by overwritten system files or by incompatible drivers. This usually happens when you install incompatible third-party software. This problem exists not only in Windows 2000 Windows XP and Windows Server 2003 but in all earlier versions of the Windows NT operating system as well. Windows 2000 Windows XP and Windows Server 2003 implement additional tools though which protect system files and drivers with a digital signature.
