savedump.exe and pagefile

Wednesday, February 14th, 2007

Today I was curious about what savedump.exe does. And after some research I found the following:

On Windows 2000 it is a part of the logon process where it copies the crash dump section from the pagefile to a memory dump and also creates a mini dump file.

On Windows 2003 and XP savedump.exe doesn’t touch the pagefile. Session manager smss.exe truncates the pagefile and renames it to dumpxxx.dmp file (copying it to the boot volume if necessary). Then savedump.exe copies that file to the correct location and then creates the mini dump file.

Also I couldn’t find savedump.exe on Vista. It looks like it was finally removed.
