How to Disable Delivery Optimization in Windows 11/10

In this post, we will show you how to permanently disable Delivery Optimization using REGEDIT, GPEDIT, Settings, etc. to stop Windows 11/10 from sharing or uploading Updates over the internet to other computers.

Delivery Optimization is a client update service that uses both local and non-local devices with the help of the internet to deliver Windows updates. This service combines data from Microsoft data centres and local devices. The combined data helps to deliver a complete update at a low bandwidth cost – and also helps in fast updates. It allows your computer may get updates from or send updates to neighboring computers or computers on your network. Although this would mean that you get updates much faster, it would also leave you behind with bigger bandwidth bills. You can stop Microsoft Windows from using your bandwidth.

Delivery Optimization is essentially a very useful feature in Windows. However, some users might experience general PC slow performance, high disk usage, and/or high CPU usage. In which case, it might serve well to disable this service.

For Windows 11/10 Home users, you can add the Local Group Policy Editor feature and then carry out the instructions as provided above or you can do the registry method below.

3] Disable Delivery Optimization via Registry Editor

Since this is a registry operation, it is recommended that you back up the registry or create a system restore point as necessary precautionary measures. Once done, you can proceed as follows:

Press Windows key + R to invoke the Run dialog.
In the Run dialog box, type regedit and hit Enter to open Registry Editor.
Navigate or jump to the registry key path below:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DoSvc

At the location, on the right pane, double-click the Start entry to modify it.
Type 4 in the Value data box.
Click OK to save the change.
Close the Registry Editor window.
Reboot your computer to save the changes.

On boot, you can check the status of Delivery Optimization service.

Do the following:

Press Windows key + R to invoke the Run dialog.
In the Run dialog box, type services.msc and hit Enter to open Services.
In the Services window, scroll and locate the Delivery Optimization service.
Double-click on the entry to check its properties.

Now you should see the service is disabled on your computer. If not, do the following:

In the properties window, click the drop-down on the Startup type and select Disabled.
Click Apply > OK to save changes.

4] Using Windows Services Manager

Sign in as an administrator and open Services Manager and locate the Delivery Optimization service. Double-click on it to open its Properties box and set its Startup type to Disable. Click Apply and restart your PC.

5] Enable Metered connection

Windows 11 or Windows 10 will not use Delivery Optimization to upload or download updates when a Metered connection is on. So enable Metered connection on your PC, to stop it from sharing Windows Updates to other computers.

This is how you can disable or turn off Delivery Optimization in Windows 11/10.

NOTE: From time to time you should check this setting as I have found that this setting reverts to On, every now and then – probably after some Windows Update.
