Microsoft Retires Windows NT 4.0
The first Microsoft network operating system to gain wide acceptance in the IT industry, Windows NT 4.0, has been officially sent riding off into the sunset.
Starting Oct. 1, NT Server 4.0 and NT 4.0 Enterprise Edition were no
longer available through volume licensing programs, according to Microsoft;Client
Access Licenses (CALs) were no longer sold. NT 4.0 is still available
through retail channels “for the foreseeable future,” but very, very few
copies of NT 4.0 are sold this way, essentially taking NT 4.0 off the
The reason, according to Redmond, is the growing demand for Windows 2000
products, including Server, Advanced Server and Datacenter Server. One
interesting option offered by Microsoft is a downgrade program, whereby
a customer would purchase NT and Win2K licenses at the same time, install
NT and upgrade to 2000 without having to buy new licenses.
Dan Kusnetzky, vice president of system software for IDC, sees both sides
of the story. On one hand, says Kusnetzky, a former software product manager,
“typically software is retired 60, 90 or 120 days after the replacement’s
launched, and it’s no longer possible to get new copies” of the old product.
On the other hand, the decision “won’t sit well with people still using
NT because it’s important to them,” Kusnetzky explained, adding that some
people “won’t be happy no matter what you do.”
Still, he says, “Microsoft has given people a rather long period of time,
which they could have been using to move to the new software if they chose.
They’ve been much more generous than most OS vendors would be.”
Support for NT 4.0 will be ongoing, according to a Microsoft statement,
and plans for how much longer it will be supported will be announced late
