Windows XP creates a prefetch file for all executables but it also requires prefetching to be enabled and working properly:<BR/><BR/>The following registry key needs to be set to 3: (it is by default)<BR/><BR/>[HKLM\SYSTEM\CurrentControlSet\Control\SessionManager\MemoryManagement\PrefetchParameters] "EnablePrefetcher"<BR/><BR/>And you system needs to go idle, it will not on battery power. So

Does anyone know for which applications the prefetch file is created and for which not?<BR/>I've noticed that for example it's created for ftp.exe but it's not created for calc.exe.<BR/><BR/>Thanks

The problem with the word caching is it implies the files are stored somewhere to be accessed later. This is not true at all with prefetching and why the word cache should not be used. Prefetching is about how the files are loaded to memory. When you launch an application it will load various files from disk to RAM. The normal process can be very innefficient and jump around the disk reading in

I knew I'd get into trouble for writing a response so hurriedly!<BR/>Please allow me to explain myself :)<BR/><BR/>Firstly: thank you for updating the info on your webpage. Also, I don't normally deal with laptops/notebooks (I still think they're toys, but that's just me ;) - I know they're not, but you get my drift), but your suggestion on how to force Task Scheduler was a good reminder to me.<

For the Prefetch files to become corrupted in the NTFS file system is very rare and a sign that something else is wrong. No file should just become corrupted. This article deals with Disk Imaging AND Slow Boot Times. This relates to corporate environments that deply systems through Images and a specific problem that can develop. This is one of many problems that can develop if Disk Imaging goes

Is it not true that there is one time and one time only that prefetch data should be cleaned, and that is when that data becomes corrupted? Typically, when it does then it starts causing problems in the applications that are being prefetched. That is my understanding at least. see <A REF="http://support.microsoft.com/kb/915163/en-us">KB915163</A> for an example.
