Issue: How to fix Teams 2.0 BSOD error on Windows?

Hello. As soon as I installed Teams 2.0 on Windows my PC crashed with a Bue Screen error. When I tried to launch the app after the crash, it happened again. How do I fix this?

Solved Answer

Following the introduction of Microsoft Teams 2.0 in September 2023, users have been reporting a worrisome Windows bug known as the Blue Screen of Death (BSOD)^[1] error. Users are upset about this unexpected system meltdown, especially since Teams 2.0 is planned to become mandatory starting in April 2024. After installing the desktop or online program, users may experience a recurrent Blue Screen of Death (BSOD). This is unsettling, and users are concerned about the possible consequences of this technical issue.

Users have also noted that the Teams 2.0 application does not have the Outlook add-in, which raises additional problems. Users who depend on the combination of these two Microsoft tools now face an additional obstacle as a result of this absence. It's a serious issue that needs to be addressed because upgrading to Teams 2.0 presents an added challenge for users due to the combination of the BSOD error and the missing Outlook add-in.

As soon as Teams 2.0 is installed, a sudden system reboot is caused by the Blue Screen error. Following that, the system crashes again when users try to log into the application for the second time. Until a fix for the Teams 2.0 issues is discovered, the only clear option available to impacted customers is to go back to Microsoft Teams 1.0.

Teamsbootstrapper.exe was launched in Teams 2.0 and was designed to be distributed to major corporations for use throughout their branches. However, teamsbootstrapper.exe installation requires an online connection, thus offline installation is not possible. This restriction adds another level of complexity for those who are having trouble connecting or who are in places where access to the internet is limited.

In addition to the BSOD error, some users encounter a termination error (0x80004004) during the installation of Teams 2.0, compounding the frustrations faced by those attempting to transition to the latest version of the Teams client. In this guide, you will find 2 steps that should help you fix the Blue Screen error appearing after Teams 2.0 installation.
