A very quick solution. I had noticed that Aero snap (dragging a maxmized window without the need for restoring to a smaller size) stopped working. A quick test showed that Aero shake to minimize all windows also stopped. This had worked before, I wonder why it turned off.
After searching around for quite some time, it turns out that I had switched off those features unintentionally. One very important setting to check is detailed below.
- Navigate to your control panel, then Ease of Use Center (open up start menu, type ease, and click the result when it comes up).
- Click ‘Make the mouse easier to use’
- Make sure that ‘Prevent windows from being automatically arranged when moved to the edge of the screen’ is not checked.
I had just wanted to turn off the feature #3 describes, however it apparently stripped away more than what it had mentioned.
If this is not the case, I would recommend following the preliminary steps here which state:
NOTE: If Aero is not enabled, then Aero Shake will still not work even when enabled or turned on.
- Aero is not included in Windows 7 Starter or Home Basic, so you must have Windows 7 Home Premium, Professional, Ultimate, or Enterprise installed.
- 1 GHz 32-bit or 64-bit processor
- 1 GB of system memory
- A graphics card with support for DirectX 9 graphics with at least 128 MB of memory.
- The graphics card must support Pixel Shader 2.0 and the Windows Display Model (WDDM).
- The Desktop Window Manager Session Manager and Themes Services need to be set as Started and Automatic.
- You must be have True Color (32 bit) set instead of High Color (16 bit).
- Desktop composition needs to be enabled (checked) in Visual Effects.
- Refresh or update your WEI score.
