Windows operating systems are known for their extensive array of background services, many of which operate automatically, often without the user’s awareness. These services, while designed to enhance functionality, can sometimes consume valuable system resources, leading to sluggish performance. By selectively disabling non-essential services, users can significantly improve their computer’s responsiveness. Below are several services that can be disabled, along with insights on their impact and instructions for disabling them.
5 Windows Search
Windows Search is responsible for indexing files, emails, and system data to provide quick search results from the Start Menu and File Explorer. While it may seem innocuous, this service can heavily tax your CPU and RAM, particularly during updates or file modifications. For users who seldom utilize this feature, disabling it can lead to noticeable performance improvements. To do so, press Ctrl + R, type services.msc, and hit Enter. Locate Windows Search, stop the service, and adjust the Startup type to Disabled or Manual for occasional use. Remember to set the Recovery tab to Take no action to prevent automatic restarts of the service.
4 SysMain (previously Superfetch)
Formerly known as Superfetch, SysMain aims to preload frequently used applications into memory, attempting to predict user behavior to enhance application launch times. However, for users equipped with SSDs and ample RAM, this service often proves counterproductive, leading to unnecessary disk activity and performance dips. To disable SysMain, access the Services app (services.msc), find SysMain, stop the service, and set its Startup Type to Disabled.
3 Windows Update Delivery Optimization
This service optimizes Windows update downloads by sharing files with other PCs, both locally and over the internet. While the intention is to enhance update efficiency, it can also consume a significant portion of your bandwidth, particularly for single PC users with limited data plans. To disable this service, navigate to Settings -> Windows Update -> Advanced Options and turn it off. Alternatively, users can limit the bandwidth used for updates, allowing for some sharing without compromising personal bandwidth.
2 Remote Desktop Services
Remote Desktop Services enable remote connections to your computer, which can be a resource drain and a potential security risk for those who do not frequently use this feature. Disabling this service can free up system resources without negatively impacting daily operations. To do so, locate Remote Desktop Services in the Services app, stop it, and set its Startup type to Disabled.
1 Connected User Experiences and Telemetry
This service is linked to Microsoft’s data collection tools, which gather information about Windows usage. Beyond consuming resources, it transmits sensitive data regarding user habits. To disable this service, it’s essential to not only turn off Connected User Experiences and Telemetry but also to navigate to Settings -> Privacy & Security -> Diagnostics & Feedback and disable Diagnostic data. Additionally, consider turning off the Diagnostic Data Viewer, which can occupy significant storage space.
There are more services you should disable
This overview represents just a selection of services that can be disabled to optimize system performance. Users with specific needs, such as those without printers, may also consider disabling the Print Spooler service, along with others like Fax, Bluetooth Support, or Windows Error Reporting Service. While each service may have a minimal individual impact, collectively, they can contribute to a more responsive computing experience, particularly on older devices.
