HSLAB Prefetch Manager Business is a tool that keeps you from waiting to start your Windows program. It runs as a background service while other applications are running or loading.
This tool works to pre-fetch files in parallel with other boot operations. It synchronizes disk I/Os efficiently and finishes most of the disk I/Os that need to be done before starting the system in parallel to device initialization delays.
This provides faster boot times and better logon performance. HSLAB Prefetch Manager Business works by tracing those frequently accessed pages and efficiently bringing them back into memory when the scenario is launched again.
When the computer is launched again, it records which pages of a file are accessed. The trace is picked up by the maintenance service and is used to update or create a prefetch-instructions file for the next launch.
