The Windows 8 Snap feature works pretty much like the Aero Snap in Windows 7 and can be used to drag windows towards the right hand side of the desktop. Unfortunately, Windows 8 has a limitation for using this feature, i.e. the Windows 8 Snap feature does not work on low resolution displays. In this post I will provide you with two simple methods for easily enabling the Windows 8 Snap on low resolution computers. To achieve this feat, you can either perform a registry hack or use a third-part application, known as the Windows 8 Snap Enabler.
To enable the Windows 8 Snap feature by using a registry hack, hit Windows+R (Win+R) hotkey from your keyboard, to open the Run dialog box and enter regedit.
Now, head over to the following path in your Windows 8 registry and make the following changes: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell\AppPositioner]
If the value does not exist, right-click on ImmersiveShell and create a new key with the name, AppPositioner. Now, create a new dword value and change it to 1.
This is obviously the easier method and is well suited for all kind sof users, especially the novice users. Just download the Windows 8 Snap Enabler application, to apply the above mentioned values automatically. To do so, launch the portable Windows 8 Snap Enabler application and click on the Enable Windows 8 Snap Feature button.
This will to enable Windows 8 Snapping on low resolution desktops. When you snap a window from the Metro Start Screen in windows 8, you are provided with two options, i.e. Snap desktop or Snap “application name”. Select Snap application name option.
The below image is an example of the Windows 8 Metro Start Screen application snap.
