how do i completely eliminate TEAMS from my pc

Dear Sheron，

Welcome to the Microsoft Community.

To remove Microsoft Teams completely from your computer, you can refer to the following method:

If you are using Windows:

You need to uninstall two items for all users on a machine to fully uninstall Teams, so make sure you follow all the steps.

1. Quit Teams by right-clicking the Teams icon in the taskbar and choosing Close window(Ignore this if you have already closed the application).

2. In Windows, click on the Start button  , > Settings > Apps.

3. Under Apps & features, search "teams".

4. Highlight Microsoft Teams, then select Uninstall.

5. A box will appear, then again select Uninstall to confirm. A new box will appear, asking Do you want to allow this app to make changes to your device? Select Yes.

6. Now select Teams Machine-Wide Installer, click Uninstall. Then follow the same process described in step 5.

If you are using Mac:

Quit Teams by right-clicking the Teams app in the dock, then holding down Option and clicking Force Quit. Open the Application Folder, select Microsoft Teams, and move it to the Trash.

I hope this is useful to you, and please feel free to contact me with any questions you may have during this process.
