This article describes a hotfix that enables a Windows 7-based or Windows Server 2008 R2-based computer to create a memory dump file even when there is no page file on the computer.
Currently, the computer must have at least one page file to create a dump file even though the system uses the dedicated dump file feature. Therefore, if there is no page file on the computer, the computer cannot create the memory dump file when the system crashes.
