How it works
After downloading, extract Update Blocker to your desired location, then run it
The status indicator displays your Windows Update service state. To halt automatic updates, select "Disable Service" and press "Apply Now." Enabling "Protect Service Settings" prevents unwanted changes (Recommended).
Blocking Additional Services and Locking Settings
The latest release lets you add any service to the configuration file for blocking. Open the INI file and insert the desired service name beneath the "dosvc=2,4" entry. For instance, to block the Windows Update Medic Service, locate it in Services.
Right-click and copy the Service Name.
Paste the service name under the dosvc=2,4 line.
Launch Update Blocker and click "Apply Now."
To remove a recently added service later, follow these steps:
- Open Update Blocker, select Enable Service, and press Apply Now.
- Remove the corresponding line from the configuration file.
- You may now select Disable Service and Protect Service Settings.
Important
If the windows update service doesn't start or if there is a problem even though you have enabled windows updates, please restart your system and try again.
When windows updates are turned off, some windows processes or programs may try to open and repair Windows updates, resulting in windows update being damaged.
Please use the Windows Update Troubleshooter from Microsoft if the updates do not open after restarting the system.
Wub software does not block Microsoft defender updates.
