Computerworld has noticed some retroactively fudged documentation which says If your PC doesn’t run Streaming Single Instructions Multiple Data (SIMD) Extensions 2, you won’t be getting any more Win7 patches. This kills off any Pentium III chips which might still be working out there.

It all started in March when the Win7 Monthly Rollup, KB 4088875, included a warning about SSE2 problems.  Microsoft was supposed to be working on a resolution and will provide an update in an upcoming release. However, this never happened. Later the notice was changed to "upgrade your machines with a processor that supports SSE2 or virtualise those machines".

In other words, Microsoft isn't going to fix the problem. It doesn't even mention the problem. And the changes were made without warning or explanation on June 15.  To be fair to Vole we can understand why it is not too keen to waste much time on this. The Pentium IIIs were sold in 2002, but Vole did promise that Win7 is supposed to be good until January 2020 so it really should be fixing it.
