Fix 1: Disable GPU Hardware Acceleration

GPU Hardware Acceleration in Microsoft Teams boosts its speed and performance but increases the CPU and RAM usage on Windows 11. To reduce it, disable the feature under Teams app settings.

Step 1: Open Microsoft Teams, click the three-dot menu at the top right, and select Settings.

Step 2: Select General from the left sidebar and uncheck Disable GPU hardware acceleration.

Fix 2: Disable Read Receipts

Microsoft Team’s Read Receipt feature provides a visual indication when a recipient reads a sent message. If you’re using a low-end computer, it can consume significant system resources, increasing CPU usage. Disable it from the in-app settings.

Step 1: Open Microsoft Teams app settings from the three-dot menu at the top right.

Step 2: Select Privacy from the left sidebar and toggle off Read Receipts.

Fix 3: Disable Teams Auto-Start

If Microsoft Teams is configured to start automatically when you boot up your Windows 11 system, it will join other startup apps to consume system resources, leading to high CPU and RAM usage.

Head to the Teams app settings > select General from the sidebar > uncheck Auto-start application to prevent it from launching automatically.

Fix 4: Turn off Animations in the Teams App

Animations in the Teams app improve its visual appeal but can quickly increase CPU usage on Windows 11. Disable it from the app settings to reduce its RAM consumption.

Step 1: Click the three-dot menu at the top right of Microsoft Teams and select Settings.

Step 2: Select Appearance and accessibility from the sidebar and toggle on Turn off animations.

Fix 5: Disable Register Teams as the Chat App for Office

Besides disabling animations, you can turn off the Register Teams as the Chat App for Office under Teams app settings to significantly reduce its CPU and RAM usage.

Open Microsoft Teams app settings, select General from the sidebar, and uncheck Register Teams as the chat app for Office. Restart your PC to apply changes.

Fix 6: Remove the Microsoft Teams App Cache

Excessive cache accumulation can cause Microsoft Teams to use more CPU resources than normal. Clearing it manually should restore its normal functioning.

Step 1: Press the Windows + R shortcut to open the Run dialog, type %appdata%\Microsoft\teams, and press Enter.

Step 2: Select the blob_storage, Cache, databases, GPUCache, and Local Storage folders. Press Delete on your keyboard to remove them.

Fix 7: Repair or Reset Microsoft Teams

Lastly, repair or reset the Microsoft Teams app to fix its high CPU and RAM usage on Windows 11.

Step 1: Open Windows Settings using the Windows + I shortcut > select Apps from the sidebar > click Installed apps.

Step 2: Search Microsoft Teams, click its three-dot menu, and select Advanced options.

Step 3: Scroll down and click Repair. If the issue persists, select Reset to restore the app to factory defaults.
