Windows 7: KB4039884 fixes dual monitor rendering bug

win7[German]Microsoft has released update KB4039884 as a hotfix for Windows 7 on August 25, 2017 to solve the dual monitor rendering bug. Here are a few details.


The issue caused by Update KB4034664 and KB4034679

Microsoft's Update KB4034664 (and KB4034679) for Windows 7 and Windows Server is causing display issues with several applications on a second screen. I've seen issues with PDF viewer, Excel, Office 2013, JAVA and Irfanview. I was also able, to reproduce the issue in Visual Basic Editor in Word 2000 (see screenshot below).
