PageDefrag is a program, developed by Sysinternals (now distributed by Microsoft), for Microsoft Windows that runs at start-up to defrag the virtual memory page file and the Registry files.
If these files are defragmented, this may improve performance. Since PageDefrag only affects a small number of files, it takes a relatively short time to run when compared to entire-disk defragmenters like Windows Defrag, so long as the page file is not fragmented. If the page file is fragmented, PageDefrag can take as long as Windows Defrag, or even longer.
PageDefrag does not defragment the contents of the Registry files, only the placement of these files on the hard drive. Numerous other utilities like NTREGOPT examine the contents of the Registry to optimize it.
PageDefrag runs on Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003. Though the website erroneously[1] says "runs on Windows XP (32-bit) and higher (32-bit), Windows Server 2003 (32-bit) and higher (32-bit)", the tool does not run successfully on Windows Vista, Windows 7, or Server 2008 and cannot defragment the pagefile on these platforms. Nevertheless, it is still able to defragment Registry hives on these as on earlier versions of Windows.
