UTCSVC: The Hidden Service That Slows Down Your PC



UTCSVC high CPU and Disk usage - How to disable utcsvc.exe?




If you notice that your Windows 10 PC is running slow or lagging, you might want to check the Task Manager and see if there is a process called utcsvc.exe that is consuming a lot of CPU and disk resources. This process is part of the Universal Telemetry Client (UTC) service, which collects and sends diagnostic and usage data to Microsoft to improve the Windows experience and quality. While this service is usually harmless and runs in the background, sometimes it can cause high CPU and disk usage issues that affect your PC performance.




UTCSVC high CPU and Disk usage – How to disable utcsvc.exe



In this article, we will explain what utcsvc.exe is, why it causes high CPU and disk usage, and how to disable it safely.


What is utcsvc.exe?




UTCSVC.exe is an executable file that stands for Service Host: UtcSvc. It runs as a Windows service called Connected User Experiences and Telemetry, or DiagTrack for short. This service enables features that support in-application and connected user experiences, such as feedback, troubleshooting, and updates. Additionally, this service manages the event-driven collection and transmission of diagnostic and usage information when the diagnostics and usage privacy option settings are enabled under Feedback and Diagnostics.


UTCSVC.exe is located in the C:\\Windows\\System32 folder and is a legitimate Windows component. However, some malware programs may disguise themselves as utcsvc.exe and run malicious code on your PC. To check if the utcsvc.exe process on your PC is genuine or not, you can right-click on it in the Task Manager and select Open File Location. If the file is not in the System32 folder, it might be a virus or malware that you need to remove with a reputable antivirus software.


Why does utcsvc.exe cause high CPU and disk usage?




There are several possible reasons why utcsvc.exe may cause high CPU and disk usage on your PC. Some of them are:


  • The service is collecting and sending too much data to Microsoft, especially after a Windows update or when you use certain applications.



  • The service is corrupted or malfunctioning due to a bug or conflict with other programs.



  • The service is infected by a virus or malware that hijacks its resources.



High CPU and disk usage by utcsvc.exe can slow down your PC, make it unresponsive, drain your battery life, and cause overheating issues. Therefore, it is advisable to disable the service if you don't need it or if it causes problems.


How to disable utcsvc.exe?




There are multiple methods to disable utcsvc.exe on your PC. You can use any of the following methods depending on your preference and system configuration:


Method 1: Disable Connected User Experiences and Telemetry Service using Service Manager

  • Right-click on DataCollection folder and select New > DWORD (32-bit) Value. Name it AllowTelemetry.



  • Double-click on AllowTelemetry value and set its data to 0 (zero). This will disable telemetry data collection on your PC.



  • Click OK and close the Registry Editor.



  • Restart your PC and check if the high CPU and disk usage issue is resolved.



Method 3: Disable Connected User Experiences and Telemetry Service using Group Policy Editor




If you have Windows 10 Pro or Enterprise edition, you can use the Group Policy Editor to disable the service. The steps are:


  • Press Windows + S to launch the search bar of your start menu. Type gpedit.msc in the dialog box.

  • Click Apply and OK to save the changes and exit.



  • Restart your PC and check if the high CPU and disk usage issue is resolved.



Tip 2: Update your drivers




Drivers are software components that enable your PC to communicate with hardware devices. Outdated or corrupted drivers can cause various issues, including high CPU and disk usage. Therefore, it is important to keep your drivers updated to the latest versions available from the device manufacturers.


To update your drivers, you can use one of the following methods:


Method 1: Update drivers manually using Device Manager




You can use Device Manager to check for driver updates and install them if available. To do this, follow these steps:


  • Press Windows + R to open the Run dialog box and type devmgmt.msc. Press Enter to open Device Manager.



  • Find the device category that you want to update and expand it. Right-click on the device that you want to update and select Update driver.



  • Select Search automatically for updated driver software. Windows will search for the latest driver online and install it if available.



  • Repeat this process for any other devices that you want to update.



  • Restart your PC and check if the high CPU and disk usage issue is resolved.



Method 2: Update drivers manually by downloading them from manufacturer's website




If Device Manager does not find any driver updates, or if you want to install specific drivers that are only available on the manufacturer's website, you can download them manually and install them on your PC. To do this, follow these steps:


  • Go to the device manufacturer's website and find the support or download section. Search for your device model and download the latest driver for your Windows version.



  • Save the driver file on your PC and run it as an administrator. Follow the on-screen instructions to install the driver.



  • Repeat this process for any other devices that you want to update.



  • Restart your PC and check if the high CPU and disk usage issue is resolved.



Tip 3: Optimize Windows 10 performance




Windows 10 has many features and settings that can help you optimize its performance and make it run faster. Some of these features and settings are:


Feature 1: Windows Update




Windows Update is a service that keeps your PC up to date with the latest security patches, bug fixes, and feature enhancements. Updating Windows regularly can help you fix performance issues and improve stability and compatibility. To check for updates on Windows 10, use these steps:


  • Open Settings.



  • Click on Update & Security.



  • Click on Windows Update.



  • Click the Check for updates button. If there are any available updates, they will be downloaded and installed automatically.



  • Restart your PC if prompted.



Feature 2: ReadyBoost




ReadyBoost is a feature that allows you to use a USB flash drive or an SD card as a cache to speed up your PC. ReadyBoost can improve the performance of your PC by reducing the time it takes to access data from the hard drive. To use ReadyBoost on Windows 10, use these steps:


  • Plug in a USB flash drive or an SD card into your PC.



  • Open File Explorer and right-click on the removable drive.



  • Select Properties.



  • Click on the ReadyBoost tab.



  • Select the Use this device option and adjust the amount of space you want to use for ReadyBoost.



  • Click OK to apply the changes.



Feature 3: Page file size




The page file is a file on your hard drive that Windows uses as virtual memory when your PC runs out of physical memory (RAM). The page file size can affect the performance of your PC depending on how much RAM you have and how much memory your applications use. By default, Windows manages the page file size automatically, but you can also change it manually if needed. To change the page file size on Windows 10, use these steps:


  • Open Settings.



  • Click on System.



  • Click on About.



  • Click on Advanced system settings from the right pane.



  • Click on the Advanced tab.



  • Under the Performance section, click the Settings button.



  • Click on the Advanced tab again.



  • Under the Virtual memory section, click the Change button.



  • Clear the Automatically manage paging file size for all drives option.



  • Select the drive where Windows is installed (usually C:).



  • Select the Custom size option and enter the initial size and maximum size for the page file in megabytes (MB).



  • Click Set to apply the changes.



  • Restart your PC to complete the process.



Note: The recommended page file size is equal to 1.5 times the amount of RAM on your PC. For example, if you have 8 GB of RAM, then the recommended page file size is 12 GB (8 x 1.5 = 12). However, you can adjust this value according to your needs and preferences.
