Windowblinds 10.8 is supposed to be compatible with the May update. Obviously title bar buttons are an issue that need to be addressed. I can live with the title bar buttons for now. Stardock needs to update WB. I'm not rolling back anything because it's a hassle man.
WindowBlinds (and Skinstudio) needs a complete overhaul to be working no matter what M$ comes up with (for most part) or there will need to be an update every 3 weeks,
Worth saying again
Unfortunately our time machine is currently broken so we cannot fix things Microsoft have yet to break
For example in Windows 1903 Microsoft added new theme parts for Light taskbar mode.
We have an internal build addressing the taskbar buttons and I am sure once this goes through QA it will be released.
It is worth noting that the current build does work, it is simply that one small part of the skin isn't being applied and instead is using the default OS theme instead.
