Windows 10 lets you link an Android or iPhone to your PC and use the Continue on PC feature. If you’d rather now allow phones to be linked, you can disable the feature with a Group Policy setting (if you have Windows Pro) or a quick Registry hack (no matter what version of Windows you have).

Note: The phone linking feature we’re talking about here is the one that debuted in the Fall Creators Update in 2017, and that’s built into Windows 10. You can access it through Settings > Phone. This is different than the “Your Phone” app Microsoft debuted in the October 2018 Update that gives Android users advanced features like texting from your PC and access your photos more easily.

All Windows 10 Users: Disable the Phone Linking by Editing the Registry

If you have Windows Home edition, you will have to use the Registry to make these changes. You can also do it this way if you have Windows Pro or Enterprise, but just feel more comfortable working in the Registry. (If you have Pro or Enterprise, though, we recommend using the easier Local Group Policy Editor, as described later in the article.)

Standard warning: Registry Editor is a powerful tool and misusing it can render your system unstable or even inoperable. This is a pretty simple hack, and as long as you stick to the instructions, you shouldn’t have any problems. That said, if you’ve never worked with it before, consider reading about how to use the Registry Editor before you get started. And definitely back up the Registry (and your computer!) before making changes.

To get started open the Registry Editor by hitting Start and typing “regedit.” Press Enter to open Registry Editor and then permit it to make changes to your PC.

In the Registry Editor, use the left sidebar to navigate to the following key (or copy and paste it into the Registry Editor address bar):

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

Right-click the Windows folder and choose New > Key. Name the new key System.

Now, right-click on the new System key and choose New > DWORD (32-bit) Value. Name the new value EnableMmx.

Now, you’re going to modify that value. Double-click the new EnableMmx value and set the value to 0 in the “Value data” box.

Click “OK” and then exit Registry Editor. For the changes to take effect, you’ll need to restart your computer. You and any other users should no longer be able to link their phones to the computer.

Download Our One-Click Registry Hack

If you don’t feel like diving into the Registry yourself, we’ve created a registry hack you can use. Just download and extract the following ZIP file:

DisableYourPhoneFeature

Inside you’ll find a REG file for disabling phone linking that adds the System key and the value EnableMmx to it in the Registry, as well as setting that value to “0.” Once it’s extracted, double-click the file, and accept the prompts asking whether you’re sure you want to make changes to your Registry. You’ll also find a REG file for re-enabling phone linking.

This hack is really just adding the EnableMmx value to the System key we talked about in the previous section, and then exported to a .REG file. Running the hack just modifies the value in your Registry. And if you enjoy fiddling with the Registry, it’s worth taking the time to learn how to make your own Registry hacks.

Pro and Enterprise Users: Disable the Phone Linking Using Group Policy

If you’re using Windows Pro or Enterprise, the easiest way to disable phone linking is by using the Local Group Policy Editor. It’s a pretty powerful tool, so if you’ve never used it before, it’s worth taking some time to learn what it can do. Also, if you’re on a company network, do everyone a favor and check with your admin first. If your work computer is part of a domain, it’s also likely that it’s part of a domain group policy that will supersede the local group policy, anyway. Also, since you’ll be creating policy tweaks for specific users, you’ll need to take the extra step of creating a policy console geared toward those users.

In Windows Pro or Enterprise, fire up the Local Group Policy Editor by hitting Start, typing “gpedit.msc” into the search box, and then clicking the resulting or hitting Enter.

In the left-hand pane of the Local Group Policy Editor window, drill down to Computer Configuration > Administrative Templates > System > Group Policy. On the right, find the “Phone-PC linking on this device” item and double-click it.

Set the policy to “Disabled” and then click “OK.”

You can now exit the Group Policy Editor and restart your machine if you want to test out the new changes you just made. If you want to re-enable the Phone-PC linking feature, just use the editor to set the item back to “Not Configured.”
