Fix Microsoft Teams high CPU usage on Windows 11/10

Fixing Microsoft Teams high CPU usage on Windows 11/10 is important, as it can slow down system performance and cause overheating. Microsoft Teams functions perfectly as a collaboration platform while using many computer resources until users fail to keep resource usage under control.

This article presents a step-by-step approach to fixed high CPU usage problems that affect Microsoft Teams. So, don’t worry, as this article is just for you!

Fix Microsoft Teams high CPU usage on Windows 11/10

Here are the most effective methods to fix Microsoft Teams high CPU usage on Windows 11 and 10. Follow each solution step by step until the problem is resolved.

Fix 1: Update Microsoft Teams

Outdated Microsoft Teams versions produce various bugs alongside performance problems that may result in high CPU utilization. The ongoing update of Teams will deliver fresh bug solutions along with enhanced performance features to your system.

1. Open Microsoft Teams.

2. Select the profile picture located at the top right corner of the screen. Select “Check for updates”.

Teams automatically procure and perform installations for available updates. Restart Teams from the dialogue after update completion to activate the recent changes.

Known bugs, together with compatibility issues, are fixed as part of Microsoft Teams updates, which leads to less CPU consumption.

Fix 2: Update Windows 11/10

The use of an old Windows operating system version leads to performance problems within Microsoft Teams. Upgrading Windows helps maintain system compatibility between all drivers and components and the newest Teams version.

1. Open Settings (Windows + I). Select Windows Update from the left-side menu.

2. Click “Check for updates”. Download and install available updates from the system.

Users should restart their computer after finishing Windows update procedures. The latest Windows version operation ensures both Microsoft Teams efficiency and minimizes CPU usage occurrences.

Fix 3: Clear Microsoft Teams Cache Data

Teams build up cached data that leads to elevated CPU usage over time. Clearing the cache helps fix performance problems.

Note: Close Microsoft Teams completely from the taskbar.

1. Users can access the Run dialog box by pressing Windows + R.

2. Enter this command in the prompt, then press Enter.

%appdata%\Microsoft\TeamsCOPY

3. Delete the following folders.

a. Cache
b. Blob_storage
c. IndexedDB
d. Local Storage
e. tmpCOPY

4. Restart Microsoft Teams. Removing cache data reduces the CPU workload because it eliminates unneeded files.

Fix 4: Adjust Visual Effects

Windows visual effects tend to boost CPU utilization during executions of CPU-demanding programs such as Teams. Setting adjustments can decrease the CPU usage load.

1. Open Settings (Windows + I). Go to “System” > “About”.

2. Click on “Advanced system settings”.

3. In the Performance section, choose “Settings” from the available options.

4. Select “Adjust for best performance”. Click “Apply” and “OK”.

The disabling of visual effects creates available system resources, which improves Microsoft Teams performance.

Fix 5: Disable GPU Hardware Acceleration on Microsoft Teams

The GPU receives graphic processing tasks through hardware acceleration, although excessive GPU workload leads to increased CPU usage. Disabling it can improve performance.

1. Open Microsoft Teams app again.

2. You can find the three-dot icon beside the profile picture at the top right corner, click on it. Select “Settings”.

2. Go to “General”. Uncheck “Disable GPU hardware acceleration”.

Restart Microsoft Teams. The system performance improves when you disable hardware acceleration because it reduces the processing requirements of your GPU and CPU.

Fix 6: Turn Off Read Receipts

When Teams generates read receipts, it needs continuous background operations that ultimately cause increased CPU resource usage. Enabling these notifications uses unnecessary resources, so administrators should disable them to save system resources.

1. In the Microsoft Teams, open the Settings menu just as we did in the previous steps.

2. Select “Privacy” > Turn off “Read receipts”.

Disabling read receipt functionality helps decrease both CPU usage levels and background system operations.

Fix 7: Disable Register Teams As The Chat App For Office

Running Teams as the active Office chat application creates constant synchronization activities that drive CPU utilization higher.

1. Open Microsoft Teams > go to “Settings”.

2. Under “General”, uncheck “Register Teams as the chat app for Office”.

Restart Teams. The modification decreases automatic synchronization operations, which in turn decreases the CPU load.

Fix 8: Repair Microsoft Teams

High CPU usage can be resolved by teaming Microsoft Teams with its repair routine to address corrupted files.

1. Open Windows 11/10 Settings app (Windows + I).

2. Open Apps from the main menu and select “Installed Apps” from the displayed options.

3. Find Microsoft Teams from the list to modify. Choose “Advanced options” from the three-dot icon.

4. Choose “Repair”.

Microsoft Teams core functions become operational again after repair, making it consume less CPU power.

Fix 9: Reinstall Microsoft Teams

The persistent CPU problems may be resolved by reinstalling Microsoft Teams.

1. Open Windows 11/10 Settings again. Open the Apps section, then select “Installed apps” from the list.

2. Launch the Microsoft Teams app from the list of installed applications, then proceed to “Uninstall”.

3. Visit the official Microsoft Store to download the most recent version of Teams. Start by installing the Teams application, followed by a restart of your computer system.

The fresh installation process removes Teams files that might be damaged to provide a clean, uncorrupted program version.
