Symptoms

Assume that you connect to a computer that is running Windows 7 or Windows Server 2008 R2 by using the Remote Desktop Protocol (RDP). The aspect ratio of the computer that you are connected to is displayed wider than a standard display aspect ratio (4:3) in full-screen mode on your local computer. In this situation, some visual elements are displayed incorrectly in the Remote Desktop session. For example, a file in the enhanced metafile format (EMF) cannot be displayed correctly.

Cause

This issue occurs because the GetDeviceCaps API returns the incorrect HORSIZE value and VERTSIZE value.

Windows 7 and Windows Server 2008 R2 file information notes


Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page.
