apply custom themes.
in order for this mod to work properly, you must include winlogon.exe and logonui.exe in windhawk's process inclusion list, in its advanced settings.
you need to first patch the theme with an invalid signature, use themetool from secureuxtheme, select your theme and click patch, then you can apply.
this is caused by logonui resetting the default colors, by reading the values located in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\DefaultColors\Standard.
this mod should fix that. if it still doesn't work, try renaming DefaultColors to something else.
the colors in control panel might be weird sometimes. works fine if you leave control panel open, then switch themes.
