Which Windows version?

For pre-w10 Windows you open regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
And you have two keys: EnablePrefetch and EnableSuperfetch; with the following values:

0 - Disabled
1 - Enabled (boot only)
2- Enabled (applications only)
3- Enabled (boot and applications) [default]

For w10 onwards open either services.msc or an administrative cmd.exe window and disable either Superfetch/SysMain service.
For command-line: sc config Superfetch start=disabled
sc config SysMain start=disabled

and reboot.
