Customers have asked that Service Packs focus entirely on quality updates. Therefore, with SP6a, we have not included new Windows NT 4.0 features. Separately included on the SP6 CD-ROM are Microsoft Internet Explorer 5, device drivers, symbol files and the Security Configuration Manager. These are not part of the SP6 updates and can be independently installed based on customer discretion. Installing SP6a provides the latest updates to Windows NT 4.0 technology.
Customers benefit from getting the most recent quality updates collected in one download.
SP6a contains the latest year 2000 updates for Windows NT 4.0, including post-SP5 year 2000 updates. These year 2000 updates are also available via a Web download that customers may apply to a Service Pack 4 or Service Pack 5 system. Please refer to the Microsoft Year 2000 Product Guide for the latest year 2000 information. For more information and to download this update, see this Knowledge Base article.
