How to Fix Microsoft Teams Keeps Reinstalling Issue

Microsoft Teams has become one of the best collaboration tools for millions worldwide. Microsoft Teams was introduced as a part of the Microsoft 365 product family, which is available for everyone as a free product.

Microsoft introduced Teams as a direct competition tool for Slack. Without a doubt, Microsoft Teams look similar to Slack in terms of all its features and functionality.

In the beginning, Microsoft Teams needed to be installed as a separate product; still, when Microsoft retired Skype for Business and replaced it with Teams, later Microsoft automatically installed a service called Teams Machine-Wide installer on all Microsoft 365 users after Microsoft Teams kept reinstalling on all the Microsoft 365 users even if they chose to uninstall it.

Now Microsoft does not install the Teams Machine-Wide install to all the user’s PC because Microsoft Teams is now included in most of the Microsoft 365 subscriptions and installed through click to run package.

As a Microsoft Teams user from the launch, I have to say Microsoft Teams wasn’t great when it was launched. Step by step, Microsoft improved the functionality and added the required features and some of them through user requests.

So, we had a lot of errors and fixes, but now I have to say Microsoft Teams is in stable condition.
