To resolve the issue where your default browser (Chrome) keeps reverting to Edge, or similar issues with Outlook and MAILTO, follow these steps:
-
Check Default Browser Settings
- Click on the Start menu and type "Default apps".
- Click on "Default apps" from the search results.
- Under the "Web browser" section, ensure Chrome is set as your default browser.
-
Reset Browser Settings
- Open Chrome.
- Click on the three dots (settings menu) in the top right corner.
- Go to "Settings".
- Scroll down and click on "Advanced".
- Under the "Reset and clean up" section, click on "Restore settings to their original defaults".
- Click on "Reset settings" in the pop-up window.
-
Update Browser
- Click on the three dots (settings menu) in the top right corner of Chrome.
- Go to "Help" > "About Google Chrome".
- Chrome will check for updates and install them if available.
-
Outlook and MAILTO Settings
- Open Outlook and click on "File" > "Options".
- Go to "Advanced" > "External server settings".
- Under "Email message", ensure "Internet Explorer" is not selected.
- Click "OK" to save changes.
-
Group Policy Settings
- Press Win + R, type "gpedit.msc" and press Enter to open Group Policy Editor.
- Navigate to "User Configuration" > "Administrative Templates" > "Windows Components" > "Internet Explorer" > "Security".
- Double-click on "Launching applications using URLs" and set it to "Disabled".
- Click "OK" to save changes.
-
Registry Editor
- Press Win + R, type "regedit" and press Enter to open Registry Editor.
- Navigate to "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\App Paths\chrome.exe".
- If the "Path" value does not exist, right-click on an empty space, select "New" > "String Value", and name it "Path".
- Double-click on the "Path" value, set its value to the path of your Chrome executable (usually "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe").
- Click "OK" to save changes.
After following these steps, your default browser should no longer revert to Edge, and Outlook and MAILTO should open correctly in Chrome.
