How can I prevent Windows 7 from changing its color scheme from Aero to Simplified?

Question

Windows

The problem periodically appears during games, for example, Battlefield 3. And on my old PC running on Core 2 Duo, there was no such trouble. Now, on a Core i5 with 16GB of RAM, the scheme is constantly changing.

Yes, and in the system tray, even with normal surfing, a message pops up about the lack of resources and a suggestion to change the theme to a simplified one.

How do I prevent Windows from changing the color scheme and let it know that its messages on this topic do not interest me?

Answer 1

This happens if the swap file is disabled or indecently small. What about you?

Answer 2

Maybe this jamb with the update was received, somewhere the developers screwed up. It is interesting to try a clean Windows with the same iron, whether the same effects will appear. Although I understand that this is not a method.
Or maybe this is a new strategy for forcing the transition to win8. Who knows them
