Question details
The Microsoft 365 Click-to-Run service keeps stopping or disabling itself on Windows 10, generating error code 0x426-0x0 and preventing Office applications from functioning properly.
- Product
- Microsoft 365
- Device & OS
- Windows 10
- Scenario

- Observed behavior
- The Click-to-Run service repeatedly becomes disabled, triggering error 0x426-0x0. Manually starting the service allows applications to open temporarily, but the service eventually stops again.

Manually Restart the Click-to-Run Service
A temporary workaround to allow your Microsoft Office applications to open by manually restarting the service and setting it to automatic.
If you need immediate access to your documents, you can manually force the service to start. Note that if your installation is severely corrupted, the service may still stop again after a short period.
Press the Windows Key + R on your keyboard, type 'services.msc' into the Run dialog box, and press Enter.
Scroll through the list of services until you find 'Microsoft Office Click-to-Run Service'.
Right-click the service and select 'Properties'. Under the General tab, change the 'Startup type' to 'Automatic'.
Click the 'Start' button under Service status, then click 'Apply' and 'OK' to save your changes. Try opening your Office application again.

Frequently Asked Questions
What is the Microsoft Office Click-to-Run service?
The Click-to-Run service is a background component used by Microsoft to deliver, update, and manage Microsoft 365 and Office 2019/2021 applications. It must be running for Office programs to launch and function properly.
Why am I getting error code 0x426-0x0 in Microsoft 365?
Error code 0x426-0x0 typically occurs when the Microsoft Office Click-to-Run service fails to start, is disabled by a third-party antivirus, or when the Office installation files are severely corrupted.
Can I permanently disable the Click-to-Run service to avoid this error?
No. Disabling the Click-to-Run service will completely break your Microsoft 365 applications, preventing them from opening or receiving necessary security updates. The service must remain active.
What is the Office Scrub tool?
The Office Scrub tool, officially known as the Microsoft Support and Recovery Assistant (SaRA), is an advanced diagnostic program provided by Microsoft that completely wipes all corrupted Office files and registry keys before a clean reinstallation.
