Superfetch feature was introduced for the first time in Windows Vista. It runs in the background and analyzes the usage pattern of RAM. Also, it keeps an eye on applications that you use more often. In other words, Superfetch make a note of apps that you use more often and mark them as “frequently used”. And then load these apps into RAM before time.
Hence, when you run the app you have visited before, it will launch faster because it is already preloaded in memory.
Superfetch use all your RAM space which is available but it uses only unused memory. So whenever some application needs RAM it free out some memory.
Two goals of Superfetch are:
1. It decreases the time to boot.
2. Load the applications efficiently that you use the most.
What is Superfetch?
Superfetch runs very smoothly that you even can’t notice in case you have a system with average or high specifications. But there are many problems associated with Superfetch. Some of them are described below:
1. As Superfetch is always running in the background, it is always using some part of CPU and RAM.
2. Also, Superfetch relocate the loading to an earlier time and it doesn’t abolish the need to load apps into RAM. Hence, when the loading takes place, your system will experience a slowdown.
3. When Windows 10 is installed on an SSD (Solid State Drive), then the performance of Superfetch is not visible because SSDs are very fast and also improves performance.
4. If you are a gamer and love playing games on the computer, then you should know that Superfetch also causes performance issues while playing games. This happens mostly in case if your system has 4 GB RAM or less. This happens because heavy games require Superfetch to load and unload data constantly.
How to Disable Superfetch on Windows?
Also, you can disable your Superfetch; there are no side effects. But in case if your system is running smoothly, then there is no need to disable it. Only disable it if you have a problem with high RAM usage, or your system’s performance is low.
So, to disable Superfetch follow the below solutions:
Solution 1: Disabling Using the Services App
Step 1: Opening services app:
Press the Windows + R key together from keyboard to invoke the Run dialog box. Now, type services.msc in the dialog box and then click on the Ok button. Services window will appear.
Step 2: Disabling Superfetch:
Next step is to search for Superfetch service from a list of services. So, scroll down until you find Superfetch. Then right click on Superfetch and select STOP.
Step 3: Preventing Superfetch from running automatically:
Again, right-click the Superfetch service and then select Properties. Superfetch properties popup will appear. Go to General tab and under the section Startup type select Disabled from the drop-down menu.
Solution 2: Disabling Using the Registry Editor
If services method doesn’t work for you, then try disabling it using Registry Editor. Follow the below resolutions to achieve this:
Step 1: Opening Registry Editor Window:
Press the Windows + R key together from keyboard to invoke the Run dialog box. Now, type regedit in the dialog box and then click on the Ok button. The Registry Editor window will appear.
Step 2: Finding the Superfetch:
On the left side of pane, browse the folders as described below: HKEY_LOCAL_MACHINE-> SYSTEM-> CurrentControlSet-> Control-> Session Manager-> Memory Management-> PrefetchParameters.
Step 3: Disabling Superfetch:
On the right side of the pane, you will see “EnableSuperfetch” key. Then, right click on it and select Modify and then Change Value data to 0 and click on the Ok button.
Optimization of System’s Performance
If you are a Windows 10 user and your system’s performance is low, the system is using too much RAM or memory then follow the below-described solution to fix this:
Solution 1: Optimization of System’s Performance By Clearing Up Junk Files
This can be achieved by using a tool “EaseUS Partition Master.” So follow the below steps to clear out junk files:
Step 1: Download the tool from location “https://www.easeus.com/partition-manager/epm-free.html”
Step 2: Launch “EaseUS Partition Master.” Then select Tools and then click on System Optimization.
Step 3: Now, click on “Junk File Cleanup.” Now, click on Analyze and EaseUS Partition master will start looking for junk files.
Step 4: Now, you can choose the junk files to clean and click on Cleanup. Selected junk file will be deleted from your system, and your system will be cleaned.
Step 5: Reboot your system and then open task manager and check if “Service Host: Local System” is normal.
Hence, Superfetch notices which applications you use more often and then load these applications from Hard Drive to RAM for easy access to the applications. On the other hand, it degrades the system’s performance by using high RAM. So, follow the above solutions one by one to fix the problem associated with Superfetch and to optimize your system’s performance.
