Mastering Office Updates: Command Line Uninstall in Windows 11

Table of Contents

Periodically, Microsoft releases updates for its Office suite to introduce new features, fix bugs, and enhance security. While these updates are generally beneficial, occasionally a specific update might cause unexpected issues, break existing functionality, or conflict with other software on your system. When such problems arise, uninstalling the problematic update becomes necessary to restore stable operation.

For many Windows users, the standard method to remove installed updates, including those for Microsoft Office, involves navigating to the “Programs and Features” applet within the Control Panel. This graphical interface provides a straightforward list of installed programs and updates, allowing for easy selection and removal. However, this method is not always available or effective for every Office update. Understanding when and why the graphical uninstall option might fail is crucial before exploring alternative methods.

Limitations of GUI Uninstall for Office Updates¶

While the Control Panel is the go-to place for managing software installations, certain conditions or types of Office updates might prevent their removal through the standard “Programs and Features” interface. This limitation isn’t arbitrary but is often related to the nature of the update or the installation method of your Office suite. Recognizing these limitations helps in determining when you need to turn to more advanced methods like the command line.

Several factors can contribute to an Office update being uninstallable via the Control Panel GUI. Some updates are foundational or cumulative in nature, integrating deeply into the Office installation in a way that doesn’t allow for simple modular removal. Others might be prerequisites for subsequent updates or components, making their individual removal risky for the overall stability of the Office suite.

Examples of Office updates that you typically cannot remove using the standard Programs and Features applet include service packs, updates specifically designed for Office Server products (which interact differently with client installations), and certain updates applied to shared components utilized by multiple Office applications. Attempting to uninstall these via the GUI will often find the “Uninstall” option grayed out or entirely absent.

Note: While not officially recommended or supported by Microsoft, it is sometimes technically possible to force the uninstall of updates marked as ‘Uninstallable’ by modifying specific registry entries. This involves creating a DWORD value named Uninstallable with data 00000001 at a particular registry path (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\Office GUID\Patches\Compressed GUID). However, proceeding with registry modifications requires extreme caution and should only be attempted by experienced users, as incorrect changes can lead to system instability or necessitate a full Office reinstallation.

Furthermore, using the Control Panel for uninstalling Office updates is contingent on certain system prerequisites being met. The Microsoft Windows Installer version 3.1 or later must have been present on the system before the potentially removable Office update was installed. Additionally, this method is most reliably available on newer versions of the Windows operating system, including Windows 11 and Windows 10, provided the specific Office update supports graphical uninstallation.

To verify if a particular Office update can be removed via the Programs and Features applet, you can follow these steps:
1. Press the Windows key + R simultaneously to open the Run dialog box.
2. Type appwiz.cpl and press Enter. This command launches the “Programs and Features” window.
3. In the left-hand pane of the “Programs and Features” window, click on the View installed updates link. This will populate the central list with all updates installed on your system, categorized by product.
4. Locate and select the specific Microsoft Office update you wish to examine.
5. Once selected, look at the toolbar at the top of the list. If the update is uninstallable via the GUI, an Uninstall button will be visible there. Alternatively, right-click on the selected update; if uninstallable, an Uninstall option will appear in the context menu. If neither option is available, the update cannot be removed using this standard method.

If you confirm that an Office update cannot be removed through the standard graphical interface, or if you encounter issues using the Control Panel, leveraging the command line provides a powerful alternative approach. This method utilizes the Windows Installer (msiexec.exe) to manage the installation and removal of software packages, including Office updates delivered in the traditional MSI format.

Uninstalling MSI-Based Office Updates via Command Line¶

For versions of Microsoft Office installed using the traditional Windows Installer (MSI) technology, which includes many older perpetual license versions and some volume license deployments, updates are often delivered as .msp patch files. When these updates cannot be removed via the Control Panel, the msiexec command-line utility offers a direct way to manage them.

The msiexec command is a versatile tool used for installing, uninstalling, and repairing Windows Installer packages (.msi) and patches (.msp). By specifying the correct parameters, you can instruct the installer to remove a previously applied patch.

The general syntax for removing an Office update (.msp file) using msiexec is as follows:

msiexec /package {product_code} /uninstall "full_path_to_.msp_file" /qb

Let’s break down this command:

• msiexec: This is the command-line tool for the Windows Installer.
• /package {product_code}: This parameter specifies the product to which the patch was applied. The {product_code} is a unique identifier (a GUID or Globally Unique Identifier) associated with your specific installation of the Office product (e.g., Microsoft Office Professional Plus 2016). You need to determine the correct product code for your Office version.
• /uninstall "full_path_to_.msp_file": This parameter instructs msiexec to uninstall a patch. You must provide the full file path to the original .msp patch file that was used to install the update. Finding the original .msp file can sometimes be challenging, as they are often temporary files used during the update process. In many cases, you might need to locate the patch within the installer’s cache or source distribution.
• /qb: This is a display option switch. /qb provides a basic user interface during the uninstall process, showing a progress bar but requiring no user interaction other than potentially a final confirmation or error message. If the update is not uninstallable, using /qb will display a message box stating “Uninstallation of the patch package is not supported.”
• /passive: As an alternative display option to /qb, you can use /passive. The /passive switch runs the uninstall automatically without displaying any user interface. If the update is not uninstallable when using /passive, the process will simply fail without displaying the specific “Uninstallation of the patch package is not supported” message box, though the command might return an error code.

Finding the correct {product_code} for your Office installation and the full_path_to_.msp_file can be the most difficult part of this process. The product code GUIDs are stored in the Windows Registry and can be found under keys related to installed software. The location of the .msp files varies depending on how the update was applied. Microsoft’s official documentation often provides details on how to identify these GUIDs and locate patch files for specific Office versions and updates.

Alternatively, a simpler command syntax can sometimes be used if you know both the Office product’s GUID and the update’s specific patch GUID:

%windir%\System32\msiexec.exe /package {Office GUID} /uninstall {Update GUID} /QN

Here:
* %windir%\System32\msiexec.exe: Specifies the full path to the msiexec executable.
* /package {Office GUID}: Still identifies the Office product installation.
* /uninstall {Update GUID}: This time, instead of the path to the .msp file, you provide the unique GUID of the specific patch or update you wish to remove. This GUID is also stored in the system’s installation data.
* /QN: This display option runs the uninstall completely silently, with no user interface shown at all. This is useful for scripting but provides no visual feedback or error messages during the process.

Determining the correct {Office GUID} and {Update GUID} requires querying the Windows Installer database on your system. Tools and methods for doing this are documented by Microsoft, but typically involve inspecting the registry or using specific command-line utilities designed to interact with the Windows Installer information.

It is important to reiterate that the methods using msiexec described above are primarily applicable to Microsoft Office installations based on the traditional MSI technology. The updates you see listed in the “Programs and Features” > “View installed updates” section of the Control Panel on Windows 11/10 PCs are predominantly those from MSI-based installations.

Handling Click-To-Run (C2R) Office Installations¶

Modern versions of Microsoft Office, including Microsoft 365 subscriptions, Office 2021, Office 2019, and non-volume license perpetual Office 2016, utilize a different installation and update technology called Click-To-Run (C2R). Unlike MSI installations, C2R streams Office components from Microsoft’s servers and updates them more frequently, essentially keeping the software “always up to date.”

Due to the nature of the C2R update mechanism, individual updates are not installed as separate, discrete patches (.msp files) that can be uninstalled. Instead, updates integrate into the existing installation, and the entire Office suite is managed as a single package version. Therefore, you cannot “uninstall” a specific C2R update in the same way you would an MSI patch.

If a recent update to your Click-To-Run version of Office causes issues, the solution is not to uninstall the update but to revert the entire Office suite installation to a previous version or “build number” that was stable before the problematic update was applied. This process is commonly referred to as rolling back.

To revert a Click-To-Run Office installation to a previous build, you must use a specific command-line tool included with the Office installation, officec2rclient.exe. Before performing the rollback, it’s crucial to prevent Office from automatically updating itself back to the problematic version immediately after the rollback is complete.

Here are the steps to revert a C2R Office installation:
1. Disable Automatic Updates: Open any Office application (like Word or Excel). Go to File > More > Account. Under “Product Information,” find “Update Options” and click it, then select Disable Updates. This action stops Office from automatically downloading and applying updates in the background. Remember to re-enable updates later.
2. Open Command Prompt as Administrator: The officec2rclient.exe tool requires elevated permissions to run. Search for “Command Prompt” in the Windows search bar, right-click on “Command Prompt,” and select Run as administrator.
3. Navigate to the Click-To-Run Directory: Use the cd command to change the current directory to the location where officec2rclient.exe is stored. The path depends on your Office version and Windows architecture:
* For Office 2016, Office 2019, Office 2021, Microsoft 365 (and later):

cd %programfiles%\Common Files\Microsoft Shared\ClickToRun\

* For Office 2013 on Windows 32-bit:

cd %programfiles%\Microsoft Office 15\ClientX86\

* For Office 2013 on Windows 64-bit:

cd %programfiles%\Microsoft Office 15\ClientX64\

4. Run the Rollback Command: Execute the officec2rclient.exe command with the appropriate parameters to specify the target build number you want to revert to. You will need to know a stable build number that predates the problematic update. Microsoft provides update history pages for different Office versions where you can find previous build numbers.

officec2rclient.exe /update user updatetoversion=BuildNumber

Replace BuildNumber with the actual version number you wish to revert to (e.g., 16.0.15928.20216).
* /update user: This parameter initiates an update process for the current user’s installation.
* updatetoversion=BuildNumber: This specific argument tells the client to update to a particular version number, effectively initiating a downgrade or rollback if the specified version is older than the currently installed one.

5. Monitor the Rollback: After executing the command, the Click-To-Run client will start checking for updates. Shortly after, a dialog box labeled “Downloading Office updates” will appear, indicating the rollback process is underway. The client will download and install the components of the specified older build. This process might take some time depending on your internet speed and the size difference between the versions. Once the process completes, the “Downloading Office updates” dialog will close, and a final dialog confirming that “Updates were installed” will be displayed, even though it was a rollback.
6. Finalize and Re-enable Updates: Click Close on the confirmation dialog. Your Office installation should now be running the previous, stable build. Test Office applications to confirm the issue is resolved.
7. Re-enable Automatic Updates: Once you are confident that the rollback has fixed the issue and you have identified the cause (or waiting for a newer, fixed update from Microsoft), it is crucial to re-enable automatic updates to ensure you receive future security patches and feature updates. Return to the “Update Options” menu in any Office app (File > Account > Update Options) and select Enable Updates.

It is vital to re-enable updates after a successful rollback. Running outdated software, especially productivity suites like Office, leaves you vulnerable to security threats and means you will miss out on important bug fixes and performance improvements released in subsequent updates. Only keep updates disabled for the minimum time necessary to resolve the issue or until a known fix is available.

Here is a summary table comparing the methods for MSI vs. C2R installations:

Feature	MSI Installation	Click-To-Run (C2R) Installation
Update Type	Individual patch files (.msp)	Cumulative build versions
Standard Removal	Programs and Features (if supported)	Not possible for individual updates
Command Line	msiexec /uninstall with patch/product GUIDs	officec2rclient.exe /update user updatetoversion=
Outcome	Uninstalls specific update	Reverts to a previous full build
Automation	Possible via scripts	Possible via scripts
Tool Used	msiexec.exe	officec2rclient.exe

Here’s a simple flow chart illustrating the decision process:

Understanding WUSA.exe¶

While discussing command-line tools for managing updates, it’s worth briefly mentioning WUSA.exe. WUSA.exe (Windows Update Standalone Installer) is a utility specifically designed to install standalone update packages (.msu files) for the Windows operating system itself. It is not used for managing Microsoft Office updates, whether MSI or C2R. If you encounter issues with Windows updates, WUSA.exe is the relevant command-line tool for installing or uninstalling those. For Office updates, you must rely on msiexec (for MSI) or officec2rclient.exe (for C2R).

Issues can sometimes arise during the uninstall or rollback process. Messages like “An error has occurred, Not all of the updates were successfully uninstalled” can indicate corruption in the installer database, conflicts with other running applications, or permissions problems. Ensuring you run command-line tools with administrator privileges and closing all Office applications before attempting an uninstall or rollback can help prevent some of these issues.

In summary, uninstalling or rolling back Office updates on Windows 11/10 depends critically on the installation technology used for your Office suite. For MSI-based installations, command-line tools like msiexec provide the means to remove specific patches when the GUI option is unavailable, although this requires technical knowledge to identify the necessary product and patch information. For modern Click-To-Run installations, a full rollback to a previous build using officec2rclient.exe is the appropriate method, which is more straightforward once you’ve identified a stable build number.
