In Windows 10, the Microsoft Edge Browser has a habit of trying to open everything as the default app. You can stop this from happening.
To stop this, and to be able to re-assign your own defaults for many different services and applications:
- Open Settings and go to System.
- Find “Default Apps” (near the bottom of the options list).
- Choose / re-assign your defaults from the list, and even assign them by the type of file they open.
