How to stop Microsoft Edge from opening automatically on your PC

There are several ways to stop Edge from opening on your PC, and you may need to try each of these methods to see what works.

Using the Registry Editor

The Registry on your PC controls many of your computer's most basic functions. Editing it without knowing what you're doing can harm your computer, but if you know where to go, you'll be fine.

1. Open the searching menu on your computer by clicking it in the bottom-left of your screen — it'll have a magnifying glass icon — or by tapping Windows Key + S on your keyboard.

2. In the search bar, search for "Registry Editor." Select it when it appears in your search results.

3. In the Registry Editor, click on the drop-down which reads "HKEY_LOCAL_MACHINE," then click on "SOFTWARE," and then the drop-down menu that reads "Policies," and then another that reads "Microsoft."

4. Right-click that last "Microsoft" folder. In the right-click menu, select the "New," and then "Key."

5. After clicking "Key," a new item will appear in the "Microsoft" folder. Right-click it and click "Rename," and then set its name as "MicrosoftEdge."

6. Right-click on "MicrosoftEdge," hover your mouse over "New" again, and select "Key" again. Rename this one "Main."

7. Right-click "Main" and hover over "New" again. This time, select "DWORD (32-bit) Value."

8. An item called "New Value #1" will appear in the white space next to your folders. Rename "New Value #1" and make it "Allow PreLaunch."

9. Double-click on "Allow PreLaunch" and a new menu will open. Make sure that the number under "Value Data" is set to zero (0). If it isn't, change it to zero.

10. Right-click the "MicrosoftEdge" folder again and create a new key. Rename this "TabPreloader."

11. Right-click "TabPreloader" and create a new "DWORD (32-bit) Value." Rename this "AllowTabPreloading" and make sure that its Value Data is set to zero, just like you did before.

12. Once you've done all this, restart your computer. Microsoft Edge will no longer start up in the background, and won't automatically load.

Removing it from the startup folder

1. Power on your Windows 10 PC, then click on the Windows key + the R key on your keyboard and a search box will open up.

2. In the search box, type in shell:startup, then click "OK" or press the Enter key on your keyboard.

3. After you finish the search, a new page will open — your "Startup" folder. If Microsoft Edge appears in the Startup folder, right-click on the icon and delete it.

3. Click on the "Sign-in options" tab in the left sidebar, then scroll down to the "Privacy" section.

4. Here, you'll need to flip off the switch that's labeled "Use my sign-in info to automatically finish setting up my device after an update or restart." Doing this will prevent Edge from continually updating itself and running in the background.
