In Windows 10 (Pro, 1511 build 10586.104), default web browser keeps being reset to Internet Explorer at each reboot (settings > system > default). No matter which other browser is set there, as admin, after reboot default browser is Explorer again.

Is there a way to prevent that?

  • Pushing IE11 instead of pushing Edge? That's weird if one assumed its all evil Microsoft's fault – infixed Mar 15 '16 at 11:01

    I have the same problem. For me, even logging off and logging back on again resets it back to IE. – Sam Jul 28 '16 at 4:09
  • I have the same issue with 1511 and 1607. I have a suspicion it may be related to synchronizing settings between machines but can't be sure until I turn that off for a while. – Speedbird186 Dec 14 '16 at 18:18

It worked for me:

1.Right click on start > Task manager

2.Click on more details

3.Go to Details tab

4.Find explorer.exe > Right click > Click "End Process" (Do not close Task manager) 5.Go to file > Run new task > type explorer.exe and check create this task with administrative privileges. > OK

6.Go to start > Setting > Apps > Default Apps > Web Browser > Click on Microsoft edge > select your favorite browser.

    Unfortunately this didn't work for me :( – Jalal Jan 10 at 11:22

Turn off Internet Explorer.

Be an Administrator user or Accept administrator prompt for this to work.


  1. Search "Turn Windows features on or off" {Control Panel > Programs > Programs and Features > Turn Windows features on or off (Visible on Left)}
  2. Disable "Internet Explorer.." from Tree

Follow these steps to change a default browser back to Firefox or Chrome

  • Click the menu button and choose Options.
  • In the General panel, click Make Default….
  • The Windows Settings app will open with the Choose default apps screen.
  • Scroll down and click the entry under Web browser. In this case, the icon will say either Microsoft Edge or Choose your default browser.
  • In the Choose an app screen, click chrome or Firefox to set it as the default browser.
  • Firefox or Chrome is now listed as your default browser. Close the window to save your changes.

Hope this answer helps
