PageDefrag is a program, developed by Sysinternals (now distributed by Microsoft), for Microsoft Windows that runs at start-up to defragment the virtual memory page file, the registry files and the Event Viewer's logs (files such as AppEvent.Evt, SysEvent.Evt, SecEvent.Evt and so on).
Since PageDefrag only affects a few files, it takes a relatively short time to run when compared to entire-disk defragmenters such as Windows Defrag, so long as the page file is not fragmented.
If the page file is fragmented, PageDefrag can take as long or longer than Windows Defrag.
Workarounds for higher versions of Windows, including 64-bit versions, include using a BartPE disk or booting from a Windows install CD and using the provided command line interface.
