Windows stores common device drivers and applications in main memory in order to improve performance. Because SSDs have very fast access times, this feature is no longer necessary.
However, I'm not sure if the "Deactivate" button deactivates the features that are bad or deactivates stopping them. Samsung Magician has some translation imperfections, which makes some settings in Samsung Magician hard to understand incomprehensible , especially in OS Optimization — Advanced tab. An easy way to understand how buttons in Samsung Magician Advanced tab work is to enable hidden system files, go to the root of system C drive, and look at creation and deletion of hiberfil.
Advanced tab uses a little bit awkward style by showing the opposite of the current status, i. Activate means that currently this feature is deactivated and Deactivate means that the feature is currently activated. For instance, pressing Activate button of Hibernation Mode instantly creates hiberfil.
On the other hand, pressing Deactivate button, instantly removes hiberfil. Buttons are showing the opposite status of the current state. Clicking the button will set it to the state that it is showing.

Note that Superfetch is not the same thing as Prefetch, the preloading memory manager introduced back in Windows XP.
Superfetch is actually the successor to Prefetch. What's the difference? Prefetch did not analyze usage patterns over time and adjust its preloading parameters accordingly. For the most part, Superfetch is useful. If you have a modern PC with average specs or better, Superfetch most likely runs so smoothly that you won't even notice it.
There's a good chance Superfetch is already running on your system right now, and you didn't even know. But there are some "problems" that can arise with Superfetch SysMain :. Superfetch has also been known to cause performance issues while gaming , particularly on systems with 4GB of RAM or less. It's unclear why this happens because it doesn't occur for everybody, but we suspect it has to do with RAM-heavy games that constantly request and free up memory, which may cause Superfetch to load and unload data constantly.
Is it safe to disable Superfetch? There is no risk of side effects if you decide to turn it off. We recommend that if your system is running well, leave it on. If it does, keep it off. Otherwise, turn it back on. However, there have been some reports throughout Microsoft user forums that sometimes the Superfetch Sysmain process actually causes performance issues. Some of these reported issues include:. If this is you, then disabling Superfetch or Sysmain may resolve the problem.
However, you may notice that launching your favorite apps may take a little longer than usual. It is a useful process that significantly cuts down on the time it takes you to launch programs that you use frequently.
However, if you are experiencing high hard drive utilization, constant memory issues, or overall poor performance, you can try disabling Superfetch to see if it resolves the problem. If it does, then leave the service disabled. Otherwise, turn it back on and continue troubleshooting. Now the SuperFetch SysMain service is permanently disabled and will not restart the next time you start your computer.
Before you start doing anything inside the registry, make sure you take a full backup of the registry first, just in case anything goes wrong. This registry entry will disable the SuperFetch SysMain service on your system. However, you may need to restart your Windows machine before this registry setting takes effect.
