Prepare for Windows Server 2003’s End of Support

By March 23, 2015September 9th, 2020Blog, Microsoft

The retirement of support for Windows Server 2003 will be one of the most important of the predictable security issues of 2015.

Microsoft officially ends support for Windows Server 2003 on July 14, 2015. The deadline has some of the same ramifications that the Windows XP deadline had: Microsoft will no longer patch Windows Server 2003 for new security vulnerabilities. Presumably, Microsoft will offer expensive Custom Support Agreements for enterprises to continue getting patch support after that date, but there’s been no official announcement yet. In the meantime, new security vulnerabilities keep cropping up for the aging OS. During the last full year, 2013, Microsoft released 37 critical updates for Windows Server 2003.

The total installed base of Windows Server 2003 remains massive, making migrations an important security issue for the entire industry. As of July, Microsoft reported that globally there are 24 million instances — half physical, half virtual — of Windows Server 2003 running on 12 million physical servers. There are 9.4 million Windows Server 2003 instances in North America. Worldwide, Windows Server 2003 accounted for 39 percent of the Windows Server installed base, according to Microsoft data.
