Speed Up Boot and Shutdown Times

Enable Quicker Startups with a Boot Defragment

On most systems, boot defragment should be enabled by default, but it may not be on yours, or it may have been changed inadvertently. To make sure that boot defragment is enabled on your system, run the Registry Editor, and go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction
Edit the Enable string value to Y if it is not already set to Y. Exit the Registry and reboot. The next time you reboot, you'll do a boot defragment.


Speed Up Shutdown Times


It's not only startup times that you'd like to speed up; you can also make sure that your system shuts down faster. If shutting down XP takes what seems to be an inordinate amount of time, here are a couple of steps you can take to speed up the shutdown process:
Don't have XP clear your paging file at shutdown
For security reasons, you can have XP clear your paging file (pagefile.sys) of its contents whenever you shut down. Your paging file is used to store temporary files and data, but when your system shuts down, information stays in the file. Some people prefer to have the paging file cleared at shutdown, because sensitive information such as unencrypted passwords sometimes ends up in the file. However, clearing the paging file can slow shutdown times significantly, so if extreme security isn't a high priority, you might not want to clear it. To shut down XP without clearing your paging file, run the Registry Editor and go to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
Change the value of ClearPageFileAtShutdown to 0. Close the Registry and restart your computer. Whenever you turn off XP from now on, the paging file won't be cleared, and you should be able to shut down more quickly.
