Windows 10 was a real review of how Microsoft handles various elements of the traditional operating system, with better support for modern hardware, but is still based on the legacy of the past. There are basic functions and pieces of code that date back to XP, 2000 and beyond. As a result, they sometimes come across features like Windows SuperFetch that have existed for years and continue to play a role in the modern Windows environment.
What is Service Host SuperFetch? What are you doing? And how do you fix it when things go wrong?
What is Service Host SuperFetch?
Windows SuperFetch was originally introduced with Windows Vista as a successor to PreFetch. It is a process that analyzes your system, in particular the RAM load, to create a profile of the programs and applications you use most frequently. While using the system, SuperFetch gradually learns what you do most and preloads the elements of those applications into memory so that they load faster than usual.
The main purpose of this function is to speed up loading times for hard disk applications, especially for older ones. Those running a Solid State Drive (SSD) will not benefit greatly from this feature, because by default, SuperFetch will not load applications into memory if an SSD is detected on the system. The service is enabled by default. If you are using a mixed drive system, for example, for example, if you use a larger disk for storage while the operating system is running on an SSD, you can improve the performance of all running applications on that disk without affect SSD operations.
If you want to check in on what effect SuperFetch might be having on your system, you might find it a little hard to spot when you first pull up the Task Manager. That's because like a number of Windows 10 services, SuperFetch isn't run as its own process, or at least, isn't listed as such. It's instead collected under a generic "Service Host."
This is all part of Microsoft moving away from the powerful, but problematic, .exe files, to something more manageable: DLL files. Today DLL files are much more commonly used within Windows, but they require a shell to host them, hence the generic Service Host for SuperFetch.
To find that process you'll need to scroll through the exhaustive list of Service Host processes to find the one called "Service Host: Superfetch."
Like many other Windows features, SuperFetch may occasionally malfunction and cause more problems than it solves. Because SuperFetch always runs in the background, it uses some system resources, such as CPU and RAM, which, if you use a highly optimized system or a particularly weak hardware, can cause slowdowns that you want to avoid.
SuperFetch can become a little too zealous with its preloading. Some have reported a slowdown when starting Windows, where their hard drive is forced to load a large number of applications before Windows has had time to load its applications and services needed. This can be useful if you want to run all these applications, but if you do not, SuperFetch slows down your computer to reduce slowdown later, which is counterintuitive.
A number of Windows users also noted that SuperFetch caused peaks in hard disk and CPU usage, especially during gaming sessions. This seems to be mainly limited to systems running on less than 4 GB of RAM. It is possible that because of the way games capture and drop RAM as needed, this SuperFetch interferes with gameplay and causes slowdowns while everything is in memory.
1. Prevent Skype From Running in BackgroundIf you use a third-party antivirus program, Windows Defender should turn off automatically. However, in some cases, this does not happen, and two antivirus programs consume resources on your computer.
Open the Google Chrome browser on your computer, click the 3-point icon, and then tap Settings from the drop-down menu.
3. Disable Windows SearchAs the name implies, Microsoft Search Indexer has created a file index on your computer designed to speed up the search process on your computer.However, it is also known that Windows search uses a large amount of system resources, especially when it enters a search cycle and runs continuously in the background.
To determine if Windows Search is causing a 100% disk usage error, you can temporarily disable Windows Search (until you restart your computer) and see if it is useful. To temporarily disable Windows search, right-click the Start button and click Task Manager. On the Task Manager screen, expand the entry for "Microsoft Windows Search Indexer." Then, right-click on Windows Search and click Stop on the shortcut menu.
If you discover that the disk usage percentage decreases after you turn off Windows Search, you can disable Windows Search permanently. To permanently disable Windows search, right click on the Start button and click Run in the menu that appears.
4. Disable SuperFetch ServiceWhile the SuperFetch service in Windows 10 can improve the performance of some applications, it is associated with high disk usage and is known to cause problems on older and less expensive computers with 4 GB or less of RAM. To disable SuperFetch, right click on the Start button and click on Run.
5. Disable Windows Defender Real Time Protection
Windows tries to help its users by displaying tips, tricks and suggestions. However, this feature has been linked to slowing down of computer by some users. You can disable this feature by going to Settings > System > Notifications & actions and toggling OFF Get tips, tricks, and suggestions as you use Windows option.
Restart your computer and you may be surprised to see it running faster than before.
6. Run ChkDsk Command
The problem of 100% Disk Usage Error in Windows 10 could also be due to problems with the Hard drive. Right-click on the Start button and click on Windows PowerShell Admin Option On the PowerShell window, type chkdsk.exe /f /r and hit the enter key on the keyboard of your computer. If you are prompted to schedule volume to be checked on next restart, type Y.
The /f in above command fixes errors as detected, while /r identifies bad sectors and tries to recover information from them. Close the PowerShell Window, restart your computer and patiently wait for Windows to scan the Hard drive for errors and repair bad sectors (if any).
