Download windows2000 sp4

These updates are a collection of fixes in the following areas: application compatibility, operating system reliability, security, and setup. If you have already installed a previous service pack, download and install SP4 without removing the previous service pack. If you install SP4 over Windows Service Pack 1 SP1 or an earlier release of Windows , your computer will automatically be upgraded to bit encryption to provide better online and local security and to bring your computer up to the current worldwide encryption standard.

Beginning with Windows Service Pack 2 SP2 , bit encryption is supported as the default, so if you previously installed SP2 or Windows Service Pack 3 SP3 , your computer has already been upgraded to this level of encryption. Important: your computer retains bit encryption even if you revert to Windows or SP1 unless you reformat your hard drive and complete a new installation of Windows or Windows with SP1.
