Uxstyle and Theme Signature Bypass for Windows 10 TH2 AKA 1511 AKA 10586

[Mr GRiM]

I've installed UXStyles and oldnewexplorer. I can't uninstall UXstyles.
But when I apply these and the poison theme, file explorer, control panel,... stays white. The box in Personalize around the themes goes dark but has a white box around it.

What am I doing wrong?

Have you followed all the instructions on the first post?
