Windows - Software - Uninstall Microsoft Office Professional Plus

What the Office Professional Plus uninstaller does

This Automox Worklet™ uninstalls Microsoft Office Professional Plus from Windows endpoints by checking for both 32-bit and 64-bit installations in the Windows registry. The Worklet targets endpoints where Office Professional Plus (ProPlusRetail) is present and removes it using Microsoft's official Office Deployment Tool (ODT).

The remediation process downloads the ODT executable, extracts it, generates an uninstall configuration XML file, and executes the setup tool with uninstall parameters. After removal completes successfully, the Worklet cleans up all temporary files from the staging directory.

The Worklet operates silently with no user interaction required, making it ideal for automated software lifecycle management across your endpoint fleet.

Why remove Office Professional Plus through Automox

Manual Office Professional Plus removal across large endpoint fleets creates licensing conflicts and software deployment failures. When IT teams manually uninstall Office on hundreds of endpoints, inconsistent removal processes leave behind registry entries, orphaned COM objects, and corrupted installation databases that prevent new Office versions from installing cleanly. These remnants cause Microsoft 365 deployments to fail with cryptic error codes, forcing technicians to spend hours troubleshooting individual endpoints and delaying critical productivity software rollouts.

This Worklet is essential for software lifecycle transitions, such as migrating to Microsoft 365 subscriptions, deprovisioning user endpoints, or refreshing your standardized software baseline. It eliminates the risk of orphaned Office installations that could conflict with new deployments or create licensing complications.

By using an automated approach, you reduce IT operations overhead, maintain compliance with your software inventory standards, and maintain accurate records of which endpoints have Office removed.

How Office Professional Plus removal works

1. Evaluation phase: The Worklet searches the Windows registry for installed instances of Microsoft Office Professional Plus. On 64-bit systems, it checks both the native 64-bit registry location (HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\) and the 32-bit compatibility location (HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\). On 32-bit systems, it checks only the standard registry path. If any matching DisplayName entry contains 'Microsoft Office Professional Plus', the endpoint is flagged for remediation.

2. Remediation phase: The Worklet creates a staging directory at C:\ODT\ and downloads the Microsoft Office Deployment Tool executable from Microsoft's official download server. After verifying the download succeeded, it extracts the ODT, creates an XML configuration file with the uninstall directive for 'ProPlusRetail' (setting Remove All="TRUE"), and executes the ODT setup tool with the configuration. Finally, the Worklet removes the entire staging directory to clean up all temporary files.

Office Professional Plus removal requirements

• Windows 7, Windows 10, Windows 11, or Windows Server 2008 and later

• Local administrator privileges required to access registry, create directories, and modify Office installations

• Internet connectivity to download the Microsoft Office Deployment Tool from Microsoft's servers

• At least 500 MB of free disk space in the system drive for ODT download and extraction

• Microsoft Office Professional Plus (ProPlusRetail) must be installed with its DisplayName registered in the Windows Uninstall registry hive

Expected state after Office Professional Plus removal

After the Worklet completes successfully, Microsoft Office Professional Plus will no longer appear in your endpoint's Control Panel Add/Remove Programs list, and the corresponding registry entries will be removed from both 32-bit and 64-bit registry locations. Users will not be able to launch Word, Excel, PowerPoint, Outlook, or other Office Professional Plus applications.

All temporary files created during the removal process, including the Office Deployment Tool executable and extracted setup files, are automatically cleaned up from the C:\ODT\ directory. The Worklet records its completion status in the Automox console, allowing you to track which endpoints successfully had Office removed across your organization.

How to validate uninstall microsoft office professional plus changes

1. Run this Worklet on a pilot Windows endpoint and review evaluation output for uninstall microsoft office professional plus.

2. Confirm Automox activity logs show successful completion and exit code 0.

3. Verify endpoint state using checks aligned to evaluation script logic, such as Write-Output, Get-ChildItem, Get-ItemProperty.

4. Validate remediation effects from script operations such as Get-ChildItem, Get-ItemProperty, Where-Object, then rerun evaluation for compliance.
