I had this issue with one of our application that is using Internet Explorer, suddenly after opening the said application, it switched to Microsoft Edge. Our application is better to use with Internet Explorer.
So, to solve this i tried the following steps and fortunately it works.
- On Windows 10, Click Windows Icon
- Click Settings
- Search “Internet Options”
- Click Internet Options
- On Internet Option Window click Advance Tab
- Go to Browsing Section
- Look for “Enable third-party browser extensions*”
- Uncheck it.
- Click Apply button.
- Open Internet Explorer again and try opening your application or website.
Let me know if you have questions.
