If you’ve noticed that your computer is running sluggishly and you’re experiencing high CPU and RAM usage, it’s possible that the MoUSO Core Worker Process is the culprit. This process is responsible for updating Microsoft Office and other Microsoft products, but it can sometimes become a resource hog. If you’re experiencing issues with high CPU and RAM usage caused by MoUSO Core Worker Process, here are some potential fixes:

1. Disable automatic updates: This is the most straightforward solution to fix the issue. You can disable automatic updates in Microsoft Office by opening any Office app, clicking on File > Account > Update Options, and selecting “Disable Updates” from the drop-down menu.

2. End the process: You can end the MoUSO Core Worker Process from the Task Manager. Press Ctrl + Shift + Esc to open the Task Manager, select the MoUSO Core Worker Process, and click on “End task.”

3. Clear the update cache: MoUSO Core Worker Process uses an update cache to store downloaded updates. Over time, this cache can become bloated, leading to high CPU and RAM usage. To clear the cache, open any Office app, click on File > Account > Update Options, and select “Update Now.” This will force Office to clear its update cache.

4. Repair Office installation: Sometimes, a corrupted Office installation can cause MoUSO Core Worker Process to misbehave. You can repair the installation by opening the Control Panel, clicking on “Programs and Features,” selecting Microsoft Office, and clicking on “Change.” From the Office installer window, select “Online Repair” and follow the prompts to repair your Office installation.

5. Create a new user profile: If all else fails, you can create a new Windows user profile. Sometimes, a corrupted user profile can cause issues with MoUSO Core Worker Process. To create a new user profile, open the Settings app, click on “Accounts,” select “Family & other users,” and click on “Add someone else to this PC.” Follow the prompts to create a new user profile.
