Hi @Mostafa Khaled
When the M365 is installed then Microsoft Teams will be installed . The method that the M365 Apps uses to install Microsoft Teams is the bulk install method with an MSI. This method is also known as the Teams Machine-Wide Installer.
Typically the Teams Machine-Wide Installer method works perfectly fine when the system has just one or two primary users. The Microsoft Teams needs an update problem starts to show up if you have a shared computer.
The Teams Machine-Wide Installer checks for something in the folder to consider Microsoft Teams as installed. By deleting or renaming that folder you can force the Teams Machine-Wide Installer to treat the user as if it was the first time they’ve logged in since the Teams Machine-Wide Installer was installed and that will trigger the Microsoft Teams install. %LocalAppData%\Microsoft\Teams
You can also download the Team Machine-Wide Installer directly and you could just remove the old version of the Teams Machine-Wide Installer and install the updated one. Now the Teams needs an update problem is fixed for new users.
