This arrived in my email today....Windows 2000 SP4 rollup....finally! :)
The Update Rollup contains all security updates produced for Windows 2000 between the time SP4 was released and April 30, 2005, the time when the contents of the Update Rollup were locked down for final testing by Microsoft and by external beta & customer sites. The Update Rollup also contains a number of updates that increase system security, reliability, reduce support costs, and support the current generation of PC hardware.
We encourage Windows 2000 SP4 customers to install this update. For more information about this release, see Microsoft Knowledge Base Article 891861.
