Windows 10: Start Menu tiles no longer transparent border after Win10 build 1151

After updating Windows 10 Pro to Fall Update 1151 (10586.71), I noticed my start menu tiles - that used to be transparent - now have the colored tile borders around them. While they change when you change the accent colors in Windows, I liked the transparency, as they once were. I've only seen a few people that actually had tiles that were ever set as transparent backgrounds, so I'm hoping creating a thread will get responses from those who've had this / know if the update caused it / maybe a way to set it back. I'm really hoping there's either a registry key to revert this back or a 3rd party program people know of that can achieve this effect. See screenshots below & thanks in advance!

how can I use windows 10 start menu with most used applications along the windows tiles

Well I am used to the build 1151 and it had much better menu layout than 1703 and 1607. i wonder if they cant be grouped in Start menu tabs

Tab Most Recent/Most Used+Tiles

Tab:App List

 

how can I use windows 10 start menu with most used applications along the windows tiles

I just found out that, but can it only shows the most used app only, and the tiles and ina separated tab the app list?
is there are way to show most used apps and tiles in the same menu and then in a menu folder/tab show the app list only? like Windows 10 build 1151
