Fix: Aero not working in Windows 10/8/7

Windows 7 does not enable Aero Glass effect on its own. Moreover, you need to verify whether your version of Windows 7 supports Aero feature or not. If you find that your Aero feature is not enabled or working in Windows 10/8/7, try these troubleshooting steps.

Aero not working in Windows 10

1] Ensure that your version of Windows 10/8/7 supports Aero. Aero is supported on Ultimate, Home Premium, Business editions.

2] Ensure that your Graphic card supports WDDM (Windows Display Driver Model)

3] Right-click on the desktop, select Personalize. Click on Themes and select the default Windows themes. Next, in Windows Color & Appearance, ensure that Enable Transparency is checked.

Enable transparency

4] Open Run box, type Services.msc and hit Enter to open Services Manager. Ensure that ‘Desktop Windows Manager’ Service is set on Automatic.

5] In spite of doing all this, you still find that Aero does not work, or your Aero has stopped working, simply copy-paste the following command in the CMD window, and hit Enter.

rundll32.exe Dwmapi.dll,DwmEnableComposition

This will re-enable Aero by flushing it.

Even if you find that your Flid3D is not working or disabled, you may try these steps.

    I checked inside my intel graphics properties, it was set to 16 bit color, When I changed it to 32 bit color, I got aero back 🙂

    For those who tried everything and nothing worked like me:|

    Press right mouse click on desktop –> Screen resolution –> Advanced options –> Screen –> de option thats most below “Amount of colours” : if it says 16bits that was your problem! set it to 32bits~!!!!
