How to:

1.Create a system restore point

2.Patch your system using ultraUXThemePatcher[https://www.syssel.net/hoefs/software_uxtheme.php?lang=en].
(Sometimes the patcher may fail to patch your system. Uninstall it and take ownership of the following files in C:\Windows\System32
uxtheme.dll, UXInit.dll and themeui.dll.
You may use this: [https://www.howtogeek.com/howto/windows-vista/add-take-ownership-to-explorer-right-click-menu-in-vista/]
Install the patcher again)

Copy the folder's contents to C:\Windows\Resources\Themes.

7.You may disable wide context menus and apply other tweaks using Winaero Tweaker

8.Use Alt + Shift + P and Alt + P to toggle the details pane and preview pane respectively

Note:
For dark themes Windows 10 loads defaults from
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\DefaultColors]
after every lock/sleep/hibernate/crash.
Make a backup of that key, take ownership of it, and then delete that whole key (defualtcolors)


Enjoy.
