Prior to Windows Vista and Windows Server 2008 we had to keep a large page file on the system drive (typically drive C:) in order to properly capture system memory dumps for troubleshooting. This presented problems as systems with very large amounts of RAM became more common, resulting in requirements for very large amounts of free space on the C: drive, or requiring that system visible memory be artificially limited for troubleshooting purposes. This is no longer a requirement thanks to the Dedicated Dump File feature, which is available for use in Windows Vista and later operating systems.
