![]() ![]() I doubt it makes any significant difference either way. My conclusion is the whole question is a nit and I don't think I'll waste any more time on it. I don't completely buy this because I have removed a couple of programs in the last few days and there are no items representing them. ![]() According to the Piriform post, that means none represent old (whatever that means) or nonexistent (removed) programs. Running CCleaner with the "Old Prefetch Data" box checked comes up with zero items as candidates for cleaning. This allows these programs to load faster. I didn't see any that did not represent currently used programs. SuperFetch and prefetch are storage management technologies in Windows that provide a fast-track access to data on traditional, slower hard drive Example of a working of prefetch and Superfetch: When you are using the computer, the prefetch files are created for the programs you normally use most often. Having said that, I took a look into the prefetch folder and found it contains some 78 items. I can understand now (at least theoretically) how going through and periodic cleanout of the shortcuts stored in the prefetch folder could initially slow down the overall system, but speed it up in the longer term.
