After Windows 7/2008 i found, that new Windows on 4k monitors with 150% fonts scale makes old Windows app blurry, for most i found solution via '~ HIGHDPIAWARE' registry option (mmc.exe and all child works fine). But Resource Monitor (for some reason resmon.exe launch perfmon.exe) left without changes and blurred fonts. I add registry keys for both exes files. Added global var __COMPAT_LAYER=HighDpiAware, no effect.
Is it possible to make DPI normal for this app? Manifest file, startup command line options?
P.S. problem solved via files permissions (i set to all involved also to system32 admin full control, yep, maybe not so secure, but is working)
