Completely remove Microsoft Teams

If you’re having problems with your Microsoft Teams installation and you cant seem to fix it then sometimes it’s worth fully removing and reinstalling.

To thoroughly uninstall Microsoft Teams from your Windows profile, follow these steps:

  1. Close all active Teams windows and processes.
  2. Open the Windows Settings app.
  3. Click on “Apps & features.”
  4. In the search bar at the top, type “Teams.”
  5. Select the Microsoft Teams application icon with the purple background.
  6. Click on “Uninstall.”
  7. Confirm the uninstallation by clicking “Uninstall” again.
  8. A dialog box will appear, asking for permission to make changes to your device. Click “Yes” to proceed.
  9. Microsoft Teams will be uninstalled from your computer.

Once Teams is uninstalled, you can remove any remaining Teams files by deleting the following folders:

  • %appdata%\Microsoft\Teams
  • %localappdata%\Microsoft\Teams

Additionally, you can delete the following registry keys:

  • HKEY_CURRENT_USER\Software\Microsoft\Teams
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Teams

To delete a registry key:

  1. Open the Registry Editor.
  2. Navigate to the registry key you want to delete.
  3. Right-click on the registry key and select “Delete.”
  4. Confirm by clicking “Yes.”

After deleting the Teams folders and registry keys, restart your computer to ensure that Teams is completely uninstalled from your Windows profile.

Webcam not working in Microsoft Teams

Recently my webcam had been playing up when joining Microsoft Teams meetings. Sometimes i’d connect to a call, audio works but video doesn’t. I could toggle the show/hide video icon and it would start working but it got worse and wouildn’t work at all.

After a bit of digging I found this article on the web and it was the following Powershell command that fixed it…

Get-AppxPackage -allusers Microsoft.WindowsCamera | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Add a guest to a team in Microsoft Teams

How do you add a guest to Microsoft teams? How does a guest join a team?

If you are trying to figure out how to add an external member to a full blown team, not just a chat or meeting then below are some articles on how to do this.

A team owner in Microsoft Teams can add and manage guests in their teams via the web or desktop. Anyone with a business or consumer email account, such as Outlook, Gmail, or others, can participate as a guest in Teams, with full access to team chats, meetings, and files. Only people who are outside of your organisation, such as partners or consultants, can be added as guests. People from within your organisation can join as regular team members.

By default, guest access is turned off. So, before guests can join a team, an admin must turn on guest access in Teams. To do that, use the link below…
