Recently we noticed some performance issues in laptops with shared graphics when the Windows 7 Basic Theme was being used (particularly with external monitors using display port cables) These issues were resolved when selecting the Windows 7 Aero Theme. We were even able to reproduce the problems on the manufacturers image.

I have asked on a few international Configuration Manager forums and apparently the Windows 7 Basic theme being used as a default is a well known issue / problem for people when you capture an image using a virtual platform such as Hyper V or VMWare. Some are deploying custom branded themes (which utilizes the aero technology) and others are setting the default Windows 7 Aero theme with Group Policy as we have done with this solution. Others are aware of the setting but have elected to do nothing and leave it as is with Windows 7 using the Basic Theme as the default.

We have applied two distinct actions.

1. Apply an additional step at the end of our build Task Sequences to run winsat.exe dwm which assesses the ability of a system to display the Aero desktop effects.

2. Created a new Group Policy which targets the Windows 7 OS version via a WMI query to set the Windows 7 Aero theme (Settings located at User Configuration \ Administrative Templates\ Control Panel \Personalization: Force a specific visual style or force Windows Classic & Load a specific theme file)

Our builds are now using Windows 7 Aero theme as the default upon login.
