That wouldn't be because Vista cache's your most used applications on startup would it........... That would speed up the artificial testing of PC Mark just a tad
Windows XP does that too.. it's called "prefetching"
Check your C:\WINDOWS\Prefetch folder
(unless you're talking about something completely different)
It's different in Vista - it's Superfetching ?
QUOTE
To start with, SuperFetch overcomes one of the big drawbacks in Windows XP's Prefetch technology. Prefetch improves efficiency by loading the majority of the files and data needed by an application or process into memory so that they can be accessed very quickly when needed. However, because these files and data exist in memory, they are subject to the laws governing virtual memory. In other words, when other applications need access to memory, any prefetched data is moved out to the page file on the hard disk. When it is needed again, it then must be moved back from the page file to memory, which of course offsets the performance enhancement.
SuperFetch goes one step further to ensure that you get the most out of the performance enhancement. In addition to constructing the map files described earlier, SuperFetch also constructs profiles of the applications you use that include information about how often and when you use them. SuperFetch then will keep track of the applications in your profile and note when any prefetched data is moved out to the page file. SuperFetch will then monitor the progress of the application that caused the prefetched data to be moved out to the page file and, as soon as that application is done, it will pull the prefetched data back into memory. So when you go to access the application, the prefetched data will again be available in memory and the application will be very responsive.
