Simple Classic Theme (fully supports Windows 8.1, 10 and 11)

I tried to press the "Install" button in the program. The program creates its own task. But it fails because the elevation check box is not checked (see figure). But even when this checkbox is checked, the program simply starts, in which you still need to press the Enable button, and not apply the classic theme right away. Therefore, I created my task.




Now I tried the /boot option, but it didn't work: the classic theme didn't apply (although the program started). Accordingly, metro-aps are working normally.


So what can you do to make the classic theme apply and the metro app work correctly?
