Adjust Transparency on Windows 10 May 2019 1903

After updating to 1903 I thought the transparency had been broken. After doing some research I figured out this was intentional. There still is a transparency effect but its 10X more blurred and makes my dark near black theme just look gray. I dislike it very much in every spot it is used. Searching around I found plenty of people like me thinking it was broken only to figure out or be told it was intentional.

Is there a simple reg hack to use the old style?

Something like this: (No longer works with 1903)
How to Increase the Transparency of Windows 10 Start Menu and Taskbar

I've tried a few apps but not had good luck. Many dont work at all and I get nervous one of them will do some real damage because it was not designed for this build.

Would much prefer a simple reg hack that changes the system blur level of Acrylic. Anyone know how to do this?

Yes, also interested in this now...

Same question here. No answers yet. Since they separate the start menu to a separated process from explorer.exe that tricks don't work anymore.
