Microsoft devs who were responsible for WinNT, Win32, IE3+ almost all retired by now. A huge brain drain. Win10 and all of their products since around 2011 are such a mess and of rather lower quality than their older products, it's not even funny anymore. It would be good for them to learn from their past mistakes, like IE and ActiveDesktop had basically the same security problems - that was fixed with WinXP and IE6, now with Win10 and Edge they are back in WinME and IE 5.5 days.
