How to stop AERO on Windows 7

To stop Aero snapping and effects in Windows 7 and return to a simpler desktop, disable the Desktop Window Manager Session Manager service. This turns off Aero features such as Snap, Peek, and Shake.

Follow these steps:

1. Click Start, type services.msc in the search box, and press Enter.
2. In the Services window, find and double-click Desktop Window Manager Session Manager.
3. In Startup type, select Disabled.
4. Click Stop to stop the service.
5. Click Apply, then OK.

Alternatively, from an elevated Command Prompt (Run as administrator), run:

net stop UxSms
sc config UxSms start= disabled

This will stop Aero and prevent it from starting again. If later wanting to restore Aero, run:

sc config UxSms start= auto
net start UxSms
