Windows – How to change the color of this area of the Windows 7 windows

Well, it is certainly possible, as the desktop modders on DeviantART have been doing it.

I would think that will need to use Resource Hacker (last beta version for x64) or similar resource editor, like XN Resource Editor and open shellstyle.dll. The bitmap that you will need to replace will be in there somewhere.

Assuming you realize this message is informing you your system is low on resources and is asking you to disable Aero so it can keep performing at optimum speed,

1. Go to the Start Menu and type Action Center on the Search box
2. Start it (it should be the top entry, under the "Control Panel" group)
3. On the left sidebar, click Change Action Center settings
4. Untick the Windows Troubleshooting checkbox, under "Maintenance Messages".
5. Click the Ok button and you are done.

Here is a screenshot of the setting screen:

Alternatively:

• You can try and keep this setting just as it is and switch to Basic desktop mode before launching the applications that usually fire up this Action Center notification. Or,
• You can right click the icons you use to fire up these full screen applications, clicking properties and under the Compatibility tab tick Disable desktop composition. This will disable the Desktop Window Manager Session Manager service during execution of this application which will increase system and video memory and avoid some application incompatibilities. A likely cause for your Action Center message if you have enough system and video memory but are stuill getting this message with certain games or full screen applications.
