Disable Windows 10 PreFetch when using an SSD

The Windows function “PreFetch” has been around since Windows Vista and is also used in Windows 10 . This prefetching function ensures that the operating system tries  to load certain areas into the working memory (RAM) before starting applications and thus accelerates the Windows system . Incidentally, this also applies to the Windows boot process and can bring a performance gain with conventional HDDs or hybrid hard drives . Certain files that are important for the boot process are summarized in certain areas so that the boot process can be carried out more quickly.

With SSDs, on the other hand, this function is useless and may even have negative influences. That is why we would like to show you today how you can deactivate this prefetch function .

Deactivate prefetch via registry

First you have to start the Windows registry editor. To do this, call using the key combination

the ” Execute ” dialog. There you enter the command ” regedit ” and press the Enter key. Then the registry editor is started and you have to call the following registry key:

Computer HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Session Manager Memory Management PrefetchParameters

Below you can see the registry editor with the key called.


There is already the value ” EnablePrefetcher “, which is set to ” 3 ” by default . This means that the start-up of programs and the Windows boot process is monitored and ” accelerated ” using prefetch . To deactivate this, you must assign the value ” 0 ” to this value .

Afterwards a Windows system restart is necessary and afterwards this prefetch option is deactivated .
