I actually do have experienced this before, quite a few times. When it did, in order to avoid a reboot I always have to poke around in the system trying to find a place where I can turn it back on. If you had experienced the same, here is a quick way to bring the Aero back without a reboot.

1. Type "Aero" in the search box in the Start Menu, and click on "Find and fix problems with transparency and other visual effects" program from the list. You may have to wait a few seconds for having it shown up.

2. An Aero Troubleshoot and help prevent computer problem wizard pops up. Click on Next button to start.

3. The wizard will then start the process trying to detect and fix any the problems related to Aero service. In most of cases, Aero will be turned back on during the process.

In addition, there are the hacks, mostly registry changes, that you can try to force the Aero enabled. However, I don’t see a need to use any of them. This simple built-in problem fix wizard is all you need.

Thanks to Glenn, who shared an even better way of re-turning Aero back on in the comment. You will have to open Dos Prompt window with administrator privilege first and run the following two command, basically to re-start uxsms, the Desktop Window Manager Session Manager service.
