2.文件对比

Cs6:CC2017

可以看出CC2017多了dpiaware：True/TM.，cs6没有定义DPIAware，但他默认是 System DPI Awareness。所以这篇文章高DPI显示屏（FIX）上的Adobe App缩放的photoshop.exe.manifest是DPIAware设置false，也就是DPI Unaware。

CC2017:2021

2018~2021多了PerMonitorV2, PerMonitor，这是新特性

3、总结

1.cs6是System DPI Awareness（系统DPI意识），会虚拟化模糊

2.CC2017首选项UI缩放在win7,win10可以设置100%和200%固定，不受系统缩放影响

3.CC2018以后首选项UI缩放只有win7不受系统缩放影响。win10跟随系统缩放而缩放。即系统有多少个缩放比例，PS就有多少。100%，125%，175%，225%等等。
