The Microsoft System Information (Msinfo32.exe) tool reports the incorrect amount of physical memory in a Windows Server 2008-based or Windows Vista Service Pack 1-based computer that has more than 4 GB of physical memory installed

Support for Windows Vista Service Pack 1 (SP1) ends on July 12, 2011. To continue receiving security updates for Windows, make sure you're running Windows Vista with Service Pack 2 (SP2). For more information, refer to this Microsoft web page: Support is ending for some versions of Windows.

Symptoms

The Microsoft System Information (Msinfo32.exe) tool reports the incorrect amount of physical memory in a Windows Server 2008-based or Windows Vista SP1-based computer that has more than 4 gigabytes (GB) of physical memory installed. Specifically, the tool never reports more than 4 GB of total physical memory. For example, assume that a Windows Server 2008-based or Windows Vista SP1-based computer has 8 GB of physical memory. However, the Total Physical Memory item under the System Summary node in the Msinfo32.exe tool reports less than 4 GB of memory.

Cause

This issue occurs because an incorrect data type is used to calculate the total physical memory in the Msinfo32.exe tool.
