The issue of not able to set Win32 program defaults

According to Windows Support website, after installing this update, some users cannot set Win32 program defaults for certain app and file type combinations. The action cannot be performed either by using the Open with… command or by clicking Settings > Apps > Default apps. For some users, instead of Win32 program defaults, Microsoft Notepad or other Win32 programs cannot be set as the default.

Though this issue may occur for some users, Windows has suggested a workaround for it. Users may attempt to set the Win32 program defaults again, and they may succeed. Users need not worry about this issue for long as Microsoft is working on a resolution. It is possible that a solution will be available in late November 2018.
