From "he who cannot be mentioned":
It only took ’em two and a half weeks.

Late Friday night, Microsoft released a hotfix for the dual-monitor rendering problem I described two weeks ago in Computerworld Two of this month’s Windows 7 patches cause second-screen problems.

In short, if you installed either of the August Windows 7 security patches KB 4034664 (the monthly rollup, installed by Windows Automatic Update) or KB 4034679 (the manual security-only patch), and you have two monitors, the second monitor will start acting up. Günter Born had a full writeup, and Christian Schwarz not only nailed the problem, he wrote a “proof of concept” program demonstrating exactly what was happening and when.

...

If you’ve already installed the August patches for Win7, and you have multiple monitors, it would behoove you to download and install the hotfix.

2015-08-15 Upgraded motherboard & RAM
2015-07-15 Upgraded LM17.1 to LM17.2
I downloaded & installed that Update. Then I received 32 Updates that I did not have, most of which were Important ones. I have my Updates set for Automatically installing them & I always install all the Windows Updates that I get notification for, so I don't know why there were so many more suddenly needed.

The KB4039884 Update required 2 restarts after the install & so did the 32 other updates.
