Disable UnUsed Background Services & Remove Built-in Useless Components and Features to Speed up Windows System

• Function : This service collects and sends your computer's usage and diagnostic data to Microsoft to improve the Windows user experience.

• Why disable it : Disabling this service reduces background CPU and network resource consumption and enhances personal privacy protection, preventing your usage data from being collected.

• Potential impact : Disabling this feature may affect some functions that rely on telemetry data, such as automatic updates and feedback functions, but it will have little impact on the daily use of most users.

• Features : Provides content indexing, attribute caching, and search results for files, emails, and other content.

• Why disable it : While it makes file searching more convenient, the Windows Search service continuously builds a file index in the background, consuming significant CPU and disk resources, especially when dealing with a large number of files. Users who don't frequently use the system search function or use third-party search tools (such as Everything) can disable it.

• Potential impact : Disabling this feature will slow down the speed at which you can find files, apps, and settings using the Windows built-in search box.

Of course, we can use a third-party search tool like Everything to replace Windows' built-in search function. The results are absolutely phenomenal; both its search speed and efficiency far surpass the system's built-in search service. And it's completely free!

• Function : By analyzing the user's memory usage patterns, frequently used applications are preloaded into memory, thereby speeding up program startup.

• Why disable it : For users of solid-state drives (SSDs), since SSDs themselves have extremely fast read and write speeds, the performance improvement brought by SysMain is limited, and may even increase the disk load due to continuous background read and write operations.

• Potential impact : Disabling this feature may slightly slow down the initial launch speed of some infrequently used applications.

• Functionality : Manages all local and network print queues and controls all print jobs.

• Why disable it : If you don't use the printer, or only use it occasionally, this service running continuously in the background will consume a small amount of system resources. Disabling it when printing is not needed will free up these resources.

• Potential impact : Printing will be impossible after disabling the service. You will need to re-enable the service if you require to use the printer.

• Functionality : Provides applications with the ability to capture, compare, process, and store biometric data, supporting functions such as fingerprint recognition and facial recognition.

• Why disable it : If your computer does not have a biometric device such as a fingerprint reader or infrared camera, or if you do not use features such as Windows Hello, then it is safe to disable this service to save resources.

• Potential impact : After disabling, all biometric-related functions (such as fingerprint login) will be unavailable.

• Function : Allows remote users to modify registry settings on this computer.

• Why disable it : For the vast majority of home users, remote modification of the registry is almost unnecessary. Disabling this service can improve system security and prevent potential malicious attacks.

• Potential impact : Disabling this feature will prevent remote management of the local registry over a network. This may affect users who require remote technical support or network management.

Program Compatibility Assistant Service

• Function : Provides support for the application compatibility assistant, monitors the programs installed and run by users, and detects known compatibility issues.

• Why disable it : This feature sometimes misjudges programs that have no compatibility issues as problematic, causing frequent pop-up prompts and affecting user experience. Experienced users can identify and handle program compatibility issues themselves, so this service can be disabled.

• Potential impact : After disabling, the system will no longer automatically prompt for program compatibility issues, requiring users to manually set compatibility mode to run some older applications.

It will take a few seconds to load, and once you are in, go to the "Tweaks" tab. You will now find two sections on the left, one for essential tweaks and another for advanced ones. I tend to focus on the former, except for disabling Microsoft Copilot, which falls under the latter. Go with entries like deleting temporary files, disabling telemetry and hibernation, and running disk cleanup. On the right, under Customize Preferences, I disable the Search button and Task View for the taskbar, since I prefer a clean look, and enable file name extensions and hidden files.
