Microsoft is pointing users to the first service pack for Windows 2000, an 87MB download that fixes an array of problems with the five-month-old operating system.

Given the sometimes unreliable nature of Windows releases, many analysts had advised companies to hold off deploying Windows 2000 until Service Pack 1 was released. Nevertheless, Microsoft claimed last month that sales hit 3 million by the end of June.

"Some customers who are more on the conservative side will possibly wait for a service pack, but all indications we had were that customers were not waiting," said Mark Perry, director of product marketing for Windows 2000 Server.

The service pack is available for download at http://www.microsoft.com/windows2000/download/recommended/sp1/default.asp/ or on CDs available through Microsoft.
