Microsoft discontinues Windows 7 support for Pentium III processors




Users of systems with SSO2 processors, such as the Pentium III, are no longer eligible for Windows 7 patches, even though official support is still running until January 14, 2020.

Stopping the support is shown by security article KB4088875 . There is a solution for not being able to update Windows 7 on computers that do not support streaming single instructions multiple data extensions 2 , or SSE2, that users have to upgrade those machines with a processor that does support them. Microsoft does not seem to fix the bug for older PCs, PCWorld notes .

According to the life cycle overview of Windows 7 with Service Pack 1, this OS should get support up to January 14, 2020, and thus patches for this kind of problem. In the original release of security update KB4088875 of March 13 for Windows 7, Microsoft first reported the update problems of PCs without SSE2. Then the text was that a solution was being worked on. This claim was repeated in later updates, such as KB4284826 of June .

That is only apparent from the pages as they are in the Wayback Machine, because in the current text of the KB4284826 update Microsoft makes no mention of the SSE2 bug at all and in March there is now the advice to upgrade hardware.

Many Pentium IIIs will no longer be used: Intel introduced the processor in 1999 and the latter was produced in 2003.
