The easiest way to spot the difference is to look at the titlebar of any window, if it is transparent Aero is enabled, if it is not Aero is disabled.Go start -> run -> services.msc and stop and/or disable the "Desktop Window Manager Session Manager" service (no thats not a typo, they have manager twice in the name). It is possible to enable Windows Aero again by performing the same steps and selecting one of the Windows Aero enabled themes from the list of available ones. The theme is applied instantly and it is possible to use the icons at the bottom of the screen to change its appearance, including changing the desktop background, color scheme or sounds. But regardless of the choice, Aero is disabled after the selection of the new theme. We suggest to pick the Windows 7 Basic theme as it resembles the default theme but with Aero turned off. To disable Windows Aero scroll down to the Basic and High Contrast Themes and select one of them with a double-click. Most themes located in here are usually original Microsoft themes, Windows 7 shipped with both Aero Themes, and Basic and High Contrast Themes. This opens the Personalization Control Panel applet, displaying all themes that are installed on the operating system. Start with a right-click on the computer desktop and the selection of Personalize from the context menu. It is thankfully not complicated to turn off Windows Aero in Windows 7, all it takes is to select one of the available Windows 7 themes without Aero support.

While this does not seem much on a system with 8 Gigabytes it could prove to be useful on systems with 1 Gigabyte or less. Systems without Aero seem to use less RAM, 50-60 Megabytes less in our case.


We have monitored the cpu usage and memory usage with Windows Aero on and off on our test system and were not able to detect any wild swings one way or the other. But not every user wants the features and effects that Aero offers, especially since Aero seems to be using additional system resources which can have an impact on systems with a low amount of computer memory.
