Windows XP Prefetch Clean And Control 1.2.0: The other day, I couldn’t delete an application file — it was locked. I rebooted but still couldn’t delete it, even though I hadn’t run the application yet.
I wonder if this is why?
Windows XP monitors the files that are used when the computer starts and when you start applications. By monitoring these files, Windows XP can prefetch them. Prefetching data is the process whereby data that is expected to be requested is read ahead into the cache. Prefetching boot files and applications decreases the time needed to start Windows XP and start applications.
