Completely Uninstall Office

Mainly for Office 2016, Office 2007, Office 2010, Office 2013,

Important: Before you begin, be aware that manually removing Office is a complex, lengthy process. If some steps are not performed correctly, you may need to reinstall your operating system.

Step 1 – Identify the installation type

Before starting the manual steps, identify your Office installation type so you can choose the correct uninstall method:

*

Click-to-Run is a newer way to install and update Office over the Internet, working much like streaming video. By default, Office 365 includes the latest version of Office, and most one-time purchases of Office 2016 products (such as Office Home & Student 2016 or Office Small Business) use Click-to-Run.

*

MSI (also known as Microsoft Windows Installer) is the traditional way to install Office from local installation resources.

Identify the installation type

1. Open an Office application, such as Outlook or Word.
2. Go to “File”>“Account” or “Office Account”.
3. If you see “Update Options”, you have a Click-to-Run installation. If not, you have an MSI-based installation.

Step 2 – Choose the installation type to uninstall

Manually remove a Click-to-Run installation of Office

Before you begin, make sure you are signed in to Windows with an administrator account. If you are unsure whether you have an administrator account, see how to determine your user account type in Windows.

Step 1: Remove the Windows Installer package

1. Find the Office 16 installation folder, usually located in C:\Program Files\.
2. Right-click the “Microsoft Office 16” folder and select “Delete”.

Step 2: Remove Office scheduled tasks (If you keep getting a message saying a 32-bit version is already installed and must be uninstalled before installing this version, completing this step is usually enough to let you reinstall.)

Open a Command Prompt window as administrator.

At the command prompt, enter the following commands, pressing Enter after each one:

schtasks.exe /delete /tn “\Microsoft\Office\Office Automatic Updates”

schtasks.exe /delete /tn “\Microsoft\Office\Office Subscription Maintenance”

schtasks.exe /delete /tn “\Microsoft\Office\Office ClickToRun Service Monitor”

schtasks.exe /delete /tn “\Microsoft\Office\OfficeTelemetryAgentLogOn2016”

schtasks.exe /delete /tn “\Microsoft\Office\OfficeTelemetryAgentFallBack2016”

Step 3: End Click-to-Run tasks using Task Manager

1. Open Task Manager.

• Windows 10: Right-click “Start”, then click “Task Manager”. (You can also use the Windows logo key + X keyboard shortcut to open the quick access menu.)
• Windows 8 or 8.1: Point to the upper-right corner of the screen, move the mouse pointer down, then click “Search”. Type “Task Manager” in the search box, then click “Task Manager” in the results.
• Windows 7: Right-click an empty area of the taskbar, then click “Start Task Manager”.

1. Click the “Processes” tab.
2. If any of the following processes are running, right-click each one, then click “End task” (in Windows 10), “End task” (in Windows 8 or Windows 8.1), or “End Process” (in Windows 7).

Officeclicktorun.exe

OfficeC2RClient.exe

appvshnotify.exe

setup*.exe

Step 4: Remove the Office service

1. Open a Command Prompt window as administrator, enter the following command, then press Enter:

• sc delete Clicktorunsvc

Step 5: Remove Office files

1. Press the Windows logo key + R to open the “Run” dialog.
2. In the “Open” box, enter %ProgramFiles%, then click “OK”.
3. Delete the “Microsoft Office 16” folder.
4. Delete the “Microsoft Office” folder.
5. Open the “Run” dialog, enter %ProgramFiles(x86)%, then click “OK”.
6. Delete the “Microsoft Office” folder.
7. Open the “Run” dialog, enter %CommonProgramFiles%\Microsoft Shared, then click “OK”.
8. Delete the “ClickToRun” folder.
9. Open the “Run” dialog, enter %ProgramData%\Microsoft, then click “OK”.
10. Delete the “ClickToRun” folder. If it does not exist, go to the next step.
11. Open the “Run” dialog, enter %ProgramData%\Microsoft\office, then click “OK”.
12. Delete the ClickToRunPackagerLocker file.

Note: If you cannot delete a folder or file because it is open or being used by another program, restart your computer and try again. If you still cannot delete the folder, go to the next step.

Step 6: Remove Office registry subkeys

Important: Follow the steps in this section carefully. Modifying the registry incorrectly can cause serious problems. Before you begin, back up the registry so you can restore it if something goes wrong.

1. Open Registry Editor.

Windows 10: Right-click “Start”, click “Run”, enter regedit, then click “OK”.

Windows 8 or 8.1: Right-click “Start”, click “Run”, enter regedit, then click “OK”.

Windows 7: Click “Start”, type “Run” in the “Start Search” box, then click “Run” in the results.

1. Delete the following registry subkeys:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppVISV

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft Office <版本> – en-us

HKEY_CURRENT_USER\Software\Microsoft\Office

Then delete the Office registry key.

Note: In the subkey in the third bullet point, “Microsoft Office <版本>- en-us” represents the actual program name. This name depends on the edition and language of Office 2016 installed.

Step 7: Remove Start menu shortcuts

1. Open a Command Prompt window as administrator.
2. Enter %ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs, then press Enter.
3. Delete the “Microsoft Office 2016 Tools” folder.
4. Delete every “<Application> 2016” shortcut for each Office 2016 application. For example, “Word 2016”, “Excel 2016”, and “PowerPoint 2016”.

Step 8: Uninstall the Office 16 Click-to-Run licensing, extensibility, and localization components

1. Open a Command Prompt window as administrator.
2. At the command prompt, enter the command appropriate for your operating system, then press Enter:

If you are running the x86 version of Office 2016 on an x64 operating system, run the following commands:

MsiExec.exe /X{90160000-008F-0000-1000-0000000FF1CE}

MsiExec.exe /X{90160000-008C-0000-0000-0000000FF1CE}

MsiExec.exe /X{90160000-008C-0409-0000-0000000FF1CE}

*

If you are running the x86 version of Office 2016 on an x86 operating system, run the following commands:

MsiExec.exe /X{90160000-007E-0000-0000-0000000FF1CE}

MsiExec.exe /X{90160000-008C-0000-0000-0000000FF1CE}

MsiExec.exe /X{90160000-008C-0409-0000-0000000FF1CE}

MsiExec.exe /X{90160000-008C-0000-1000-0000000FF1CE}
