Operating systems are Windows XP/2003/Vista/2008 component preloading (prefetcher), which reduces the time it takes to load Windows and run programs.
Sometimes there may be problems with loading or running Windows programs. In this case it is useful to disable prefetcher, using HSLAB Prefetch Manager.
During the Windows boot system stores data about the reading of all logical drives. On subsequent downloads of this information is used for parallel prefetching in memory of the files needed to start the system. During the boot process and run the Windows application requests a memory page for storing data in small blocks (4 KB to 64 KB), for files, directories, and metadata.
The system pre-boot, which first appeared in Windows XP, download most of these data in the system cache with efficient asynchronous mechanism of the disk, which minimizes disk access and faster system performance.
During the boot prefetcher finishes most of the disk I / O required to start the system in parallel mode, preventing delays in the device initialization, reduces download time and login.
The system pre-loading learns by tracking the most frequently recurring transactions (scenarios) and efficiently loads into memory the necessary components at the next startup script. In
