WARNING: THIS BREAKS A LOT OF STUFF INCLUDING THE UI. Just kill all modern apps, suspend sihost.exe, kill explorer.exe, suspend winlogon.exe, and then kill dwm.exe using your preferred task manager.

If one of you finds out how to get the Windows Basic and Windows Classic themes in Windows 10 (preferrably version 1909 or 2004), be sure to tell me about it in this thread. Being able to customize the appearance like that would be awesome. were to be ported over from Windows Vista/7. I think it would be really cool if the theme customization control panel, which let you change various aspects of themes like the desktop background color, title bar size, etc. I know of a tweak that allows you to get the Windows Classic theme on Windows 10, but that appears to be adding new functionalities rather than modifying existing ones. Using a similar technique you might be able to unlock a Windows Classic theme as well, since the video I mentioned above also shows Windows Vista/7's fallback theme on Windows 10, which is a derivative of the Windows Classic theme as far as I can tell. This would only change things like window borders, since the taskbar's appearance (apart from color) isn't changed with themes like in Windows 7.

I don't mean using a custom theme installed by patching uxtheme.dll and stuff, I mean actually unlocking the hidden Basic theme. I'm wondering if it would be possible to force Windows 10 to use the Basic theme without breaking the OS like that.
