System Restore and other features of Windows XP also attempt to defer some work until the system is deemed to be idle. The file placement optimization, which is done no more often than once every three days, is an example of a task that is carried out when the system is deemed to be idle. Idle Task Scheduling: The ProcessIdleTask API

I note only to the curious that the process rebuilds your prefetch cache, and if this is something you have wanted to do you might as well accomplish the prefetch optomization along with the physical defragmentation/location feature of your Startup files at the same time. For the serious fanatics, I include below the MSDN description of the process. If you schedule it note that XP essentially does this incrementally every three days with sufficient idle time. To call it directly, copy the line above and then Start, Run, and paste the line into the window. This is the core of the Bootvis.exe optomization tool, and you can call it directly or schedule it. In the background this will take about 10-15 minutes to complete.

Rundll32.exe advapi32.dll,ProcessIdleTasks No matter, you can do your own Bootvis-style optomization even without the software.Īn odd discovery I explored, (and much thanks to David Candy), shows that you can force a bootvis optomization in the background of XP. I like the utility Bootvis.exe, but Microsoft no longer offers it for download.
