How to Stop Win10 from Resetting Default Apps?

Preface

Win10 is more modern than previous versions of Windows, yet it isn't necessarily easier to use. Its habit of arbitrarily resetting default apps is a major problem.

Just like this—it's really annoying.

Solution

Edit the registry. Create a registry file named 去除重置默认应用.reg and paste the following code.

Windows Registry Editor Version 5.00

;Description: Prevents Windows 10 from resetting the file associations

;... by setting NoOpenWith registry value for all the modern apps.
