By now the regedit window should be up. Continue with the next move.

Click on it.
On the Services window, look for SuperFetch under the name column. You might need to scroll to find SuperFetch.
Double click on SuperFetch there to bring up its properties window.
Click on the Stop button once.
And click on OK on the SuperFetch properties window.
We are done with the Services window, so go ahead and close it.
Now on the regedit page – Registry Editor.
Expand the HKEY LOCAL MACHINE folder.
Next is to expand the SYSTEM folder.
Now expand the CurrentControlSet folder.
Widen the width of the folders name section so to be able to see the full names of the folders.
Expand the Control folder.
Scroll down to expand the Session Manager folder.
Expand Memory Management folder.
This is important:
Left click on PrefetchParameters folder. Then look at the right hand side of the page.
We will work on EnablePrefetcher and EnableSuperfetch.
Starting from EnablePrefetcher, double click on it to open its Edit DWORD value.
The value data box is the important thing here, while you leave the Base at Hexadecimal.
If you put 0 as the Value Data, you will completely disable the EnablePrefetcher.
And 1 will enable EnablePrefetcher for only applications.
If you put 2, you are setting EnablePrefetcher for at booting – when you are powering up the computer.
And 3 will EnablePrefetcher for both applications and booting.
You have got choices, now what should you do?
From my experience:
When using hard disk drive, HDD, I observed that setting the Value Data to 2 is the best option. You are free to test all the numbers and come up with the one that suits you best. But on the other hand when using SDD, setting the Value Data to 0 is the best option.
Repeat the same thing for EnableSuperfetch. If you are using HDD set the Value Data to 2 and if you are using SDD set your Value Data to 0. And after the setting the Value Data restart your computer and now you have disabled the service host superfetch that is slowing down your computer.
