Despite Microsoft's promise of support until 2020, Windows 7 users running older hardware are getting the shaft: those with a Pentium III, for instance, will no longer be able to install monthly rollups or security-only patches. This is related to a bug that Redmond is allegedly ignoring, leading some to believe that MS is "already killing off Windows 7."

Up until June 15, Microsoft was promising that it would fix the bug that prevented Win7 Monthly Rollups and Security-only updates from installing on older pre-SSE2 machines. After June 15, Microsoft wrote off the pre-SSE2 population, without notice or fanfare, and retroactively changed the documentation to cover its tracks.
