Description:
Prefetch is a utility that loads commonly used applications to ram when the system starts. Windows retains a copy of a portion of a program in the prefetch folder even if you use it only once. The prefetch folder is used to help speed up the loading of programs. Windows do load programs it thinks you need before you ask for them yourself. This may affect performance of your system by having portions of a program you do not use loaded in your system's memory. Therefore, it is suggested that you periodically empty the prefetch folder. Now, you can change the way that prefetch behaves by making a change in the registry. This is helpful when you want to alter prefetch or disable prefetch completely. <table><tr><td><span style="font-family: verdana; color: black; font-size: 11px; font-weight: 700">prefetch_code</span></td><td><span style="font-family: verdana; color: black; font-size: 11px; font-weight: 700">behavior</span></td></tr><tr><td><span style="font-family: verdana; font-size: 11px; color: black">0</span></td><td>disable</td></tr><tr><td><span style="font-family: verdana; font-size: 11px; color: black">1</span></td><td>application launch prefetch</td></tr><tr><td><span style="font-family: verdana; font-size: 11px; color: black">2</span></td><td>boot prefetch</td></tr><tr><td><span style="font-family: verdana; font-size: 11px; color: black">3</span></td><td>prefetch everything</td></tr></table> for this, go to start > run menu, enter regedit and navigate to the registry path listed below.
