It is very annoying to wait longer times for an application to start or load. You can speed up the loading of any of your applications with this simple registry hack. The Windows prefetcher aims to load applications faster by “pre-fetching” the application and storing it in the pre-fetch cache. You can speed up application loading by changing the default value of one the settings under the relevant key.
The default value for the EnablePrefetcher setting is 3. Change this value to 5 to make applications load faster. You can experiment with higher values – up to 9 – and see if you get a further improvement. Since this relates to the system, a reboot is required for the change to take effect.
