Windows NT 4.0 SP6a Patches
Note: Microsoft has announced that it will stop supporting Windows 98 and Windows NT 4.0 Workstation as of June 30, 2003.
What was the latest SP for Windows NT 4.0?
Windows NT 4.0 Service Pack 6a, the most recent service pack for Windows NT, was released in November of 1999. Microsoft originally planned to release Windows NT 4.0 SP7 in late 2000, approximately one year after the release of Windows NT 4.0 SP6a. At the time, Microsoft had produced relatively few post-SP6a hotfixes, and decided to delay Windows NT 4.0 SP7 until the third quarter of 2001. The frequency of hotfixes has continued to decline, and now, well over 2 years beyond the last Service Pack release, they still have made fewer fixes than were included with either Windows NT 4.0 SP5 or SP6.
There were three reasons why customers were anticipating Windows NT 4.0 SP7:
An easy mechanism for deploying all the security fixes Microsoft has publicly released since Windows NT 4.0 SP6a – the post-SP6a Security Rollup Package (SRP) is now available for download here – 299444
Availability of the Windows NT 4.0 Active Directory client, originally planned to be part of SP7 – it is now available for download HERE
International versions of the Internet Explorer High Encryption Pack for Windows NT are available for download HERE
Microsoft has concluded that Windows NT 4.0 SP7 is not needed, but that an easy way to deploy publicly released security fixes would be appreciated by many of their customers.
Microsoft has released a Security Rollup Package (SRP) for Windows NT 4.0 that includes the functionality from all security patches released for Windows NT 4.0 since the release of Windows NT 4.0 Service Pack 6a (SP6a) . This small, comprehensive rollup of post-SP6a fixes provides an easier mechanism for managing the rollout of security fixes. Please refer to Microsoft Knowledge Base article 299444 for more information about this rollup package. Applying the SRP does not change the encryption level of your computer.

A note for Hebrew-enabled Windows NT users
Make sure you download the correct version of the service pack or HotFix. If you cannot find a Hebrew version – DO NOT download it! Consult Microsoft Israel for a suggested patch.
If you apply non-Hebrew versions of the patches on your Hebrew enabled Windows NT 4.0 you will see all sorts of strange fonts, dialog windows and error messages might become unreadable or written in a mixture of English and Hebrew fonts, and finally, you might experience BSODs. Uninstalling the problematic patch might not help, and you’ll have to re-install NT.
See the Language Versions of MS Products – Hebrew article for some more info.
