Windows 10 update

In February 2025, Microsoft began a mandatory update for Windows 10 users that included the forced installation of the new Outlook app as part of a strategy to integrate it into their ecosystem. This installation is linked to the KB5051974 update, which is a critical security patch. Users can prevent the new Outlook from being installed by modifying the Windows registry, specifically by creating a new string value named BlockedOobeUpdaters and setting its value data to ["MS_Outlook"]. This process must be repeated with each subsequent Windows 10 update. For users who have already had the new Outlook installed, it cannot be uninstalled through standard methods but can be removed using Windows PowerShell with the command: Remove-AppxProvisionedPackage -AllUsers -Online -PackageName (Get-AppxPackage Microsoft.OutlookForWindows).PackageFullName. Additionally, to uninstall unsupported Mail or Calendar apps, the command is: Get-AppxProvisionedPackage -Online | Where {$.DisplayName -match "microsoft.windowscommunicationsapps"} | Remove-AppxProvisionedPackage -Online -PackageName {$.PackageName}.
