Microsoft repairs buggy Win7 safety patch with buggy hotfix KB 4039884


Two weeks in the past, I talked a few bug in Home windows 7’s August Month-to-month patch rollup KB 4034664 that left many individuals who've two screens reeling. After putting in the safety patch, the primary monitor would work correctly, however the second monitor may have all types of rendering issues.

Günter Born had a full writeup about the issue, and Christian Schwarz not solely nailed the problem, however he wrote a “proof of idea” program demonstrating what was taking place and when.

The bug additionally seems in KB 4034679, the manually put in security-only patch for August, and in KB 4034670, the Preview of September’s Month-to-month rollup. Bugs as a Service.

Microsoft got here up with a manual workaround. First, you allow Desktop Composition (see TechSupp247’s video), you then ensure the principle monitor is within the higher left (the “1” place) in monitor format. That labored, generally, however older graphics playing cards don’t help Desktop Composition, and the handbook process is a typical convoluted Home windows process — not appropriate for non-combatants.
