Permanent fix for “Do you want to change the color scheme to improve performance?” warning? [duplicate]

Solution 1:

I've finally found a solution!

Since Windows doesn't understand how resources work, you need to keep it from checking them:

In regedit go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM (create if not already existent)

Set a new DWORD UseMachineCheck with a value of 0.

This will keep Windows from checking if your computer "performs slowly" and thus attempting to disable Aero.

Solved all my problems!
