The next UI windows showed me available filetype associations, including HTTP and HTTPS currently associated with Firefox. Using the Default Programs Settings option showed a different UI window where I selected Google Chrome to change default associations: Note the registry settings ( a) and program settings ( b) options. To change my default browser from Firefox to Chrome using the app I just double-clicked on the Default Programs Editor.exe file. For example, my default browser is Firefox… but I also have Google Chrome installed. Well, duh… that’s its sole purpose so IMO this is a false positive that can be ignored.) (Please note: VirusTotal shows 1/71 security vendor flagged the single program executable to be malicious due to a ‘Mitre signature’… not because of any malware detections but because it changes the registry. If you download, unblock then unzip the archive you will find a single program executable ( Default Programs Editor.exe) and a changelog text file. Instead, consider using a freeware portable app called Default Programs Editor to achieve the same with far less effort (and NO registry editing).
However, IMO it’s like using a sledgehammer to crack a nut. As you have a Pro version of Windows 10 you could follow Google’s own instructions about how to use Windows 10 Pro’s Group Policy Editor to force a change of browser default.
