''Startups''!

Mar 16, 2004 11:56PM PST

The WinXP Cache Manager monitors page faults (both those that require that data be read from disk (hard faults) and those that simply require that data already in memory be added to a process's working set (soft faults)) occurring during boot and application startup. By default, it traces through the first two minutes of the boot process (60 seconds following the time when all Win32 services have finished initializing or 30 seconds following the start of the user's shell (typically IE), whichever of these three events occurs first and also monitors the first 10 seconds of application startup). After collecting a trace that's organized into faults taken on the NTFS Master File Table (MFT) metadata file (if the application accesses files or directories on NTFS volumes), the files and the directories referenced, it notifies the prefetch component of the Task Scheduler by signaling a named event object which then performs a post-processing on the trace data and writes it out to a file in the \Windows\ "Prefetch" folder.

a. Opinions concerning system operation/speed if a user right-clicks the tasks in the Scheduled Tasks window, Properties, and on the General tab, clears the Enabled check box.

==or==

b. Any hints concerning the disabling of the process every three-day whereby it organizes a list of files and directories in the order they are referenced during boot or application starts, and then stores the list in a file named \Windows\Prefech\Layout.ini.
