Microsoft’s Forced Installation of New Outlook: A Step-by-Step Guide to Prevention and Removal

Introduction

In a move that has left many Windows 10 users disgruntled, Microsoft has recently implemented a mandatory update (KB5051974) that forces the installation of the new Outlook app on their PCs. Previously, Microsoft had stated that this forced installation was unavoidable, but recent discoveries have revealed a workaround that allows users to prevent it.

Preventing the Forced Installation

To prevent the new Outlook from being installed along with the mandatory update, users can edit the Windows registry. However, it is crucial to note that this should only be attempted by users who are familiar with the Windows registry. Incorrect modifications can cause system crashes or permanent damage.

1. Press Windows Key + R to launch the Run dialog box.
2. Type regedit and click OK to open the Registry Editor.
3. Navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update
4. Right-click on an empty space in the right pane and select New > DWORD (32-bit) Value.
5. Name the new value ExcludeW10FeatureUpdates.
6. Double-click on the newly created value and set its Value data to 1.
7. Click OK to save the changes and close the Registry Editor.

Uninstalling the New Outlook

If the new Outlook app has already been installed on your PC, all is not lost. You can uninstall it manually using the following steps:

Step-by-Step Guide to Uninstalling New Outlook
