Win10 a more memory-blooded SuperFetch service to be so correct

When running Windows 10 on a general-purpose computer, the system often optimizes content through web searches or pre-compiled skills. However, one issue that many users face is the SuperFetch service. Even if you disable it, after a major Windows 10 update—whether it's a version, quarterly, or quality update—it tends to re-enable itself. This is why some users notice their systems slowing down over time, as SuperFetch can consume significant memory and CPU resources.

If you're not familiar with what SuperFetch does, it’s a background service designed to improve performance by preloading commonly used applications into memory. The idea is to reduce startup times for frequently used programs. While this concept sounds great, it may not be ideal for all systems—especially those with lower specs. On such machines, SuperFetch can actually cause performance issues due to excessive resource usage.

As a built-in Windows 10 service, Microsoft enables SuperFetch by default to ensure system stability. However, if you want to disable it completely, you'll need to use the registry editor. Here’s how you can do it:

Press Win + R, type "regedit", and hit Enter to open the Registry Editor. Navigate to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SysMain

On the left side, create a new key named "Superfetch". Then, on the right side, create a new DWORD (32-bit) value called "Start" and set its value to "3".

Next, go to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TimeBrokerSvc

Change the "Start" value here to "3" as well.

After making these changes, log off your account or restart your PC. This should effectively disable SuperFetch, preventing it from consuming unnecessary memory and CPU resources. As a result, your system will run more smoothly, and you’ll avoid the common issues of lagging or freezing that some users experience.
