How do i disable superfetch

To reiterate, we don't recommend disabling Superfetch except as a troubleshooting measure for the potential issues mentioned above. Most users should keep Superfetch enabled because it does help with overall performance. If you aren't sure, try turning it off. If you don't notice any improvements, turn it back on. Again, Superfetch is referred to as SysMain in Windows So that's what users should be looking for when disabling it.

The Services app is the preferred method for this, but if it doesn't work for some reason, you can always edit the registry key directly. Before you do this, make sure you back up the registry in case something goes wrong. Please note that it's important to create a System Restore point before making any Registry changes.

You can revert to this restore point in case of any mishap. The fastest way to disable Superfetch and feel like a Windows power user while doing so is to use the Command Prompt. Superfetch isn't the only example of a feature that might be better off disabled. Tons of other features are better left disabled due to the performance trade-off. That said, there are a few reasons you might want to choose to disable Superfetch on your PC.

A list of values and their corresponding settings should now be displayed on the right side of the Registry Editor interface.

Double-click EnableSuperfetch. Enter 0 in the Value data field. Select OK. Superfetch should now be disabled.

But what is Superfetch? In the latest versions of Windows 10, the Superfetch service now shows up under the name SysMain. The service focuses on pre-loading apps into unused RAM. All of this is unnoticeable to the general user.
