But judging by the abysmal state of Microsoft modern UI toolkits, and Microsoft's complete inability to adhere to any consistency between the different frameworks that render toolkits, I just don't see any way Microsoft could offer cross-OS theme support that would work in any meaningful way. This was possible up to and including Windows 7, but then Microsoft just derped in their UI development, and it has been more and more embarrassing with every Windows release.
Click the "System DSN" tab, then "Add", Double-click the top entry ("Driver Da Microsoft..."), uncheck "Use Current Directory", then click the "Select Directory" button.
Also try the "help" button.

The open source Windows all I maintain still uses this paradigm, and there's not really a good migration path to anything else, and Microsoft refuses to fix the chrome.
Aero looks like this:

As a "family admin" I'd want to update for security reasons, or if the new version is better optimised or lacks some bugs, but for many elders (IME) any significant changes to UI are devastating to their comfort in using the OS.
MS just don't seem good at making windows (a DE), IMO.
