Windows 10: Identification of default browser in registry?

Is there some place in the registry that identifies the default browser?

I've already found HKEY_CURRENT_USER\Software\Clients\StartMenuInternet, but that continues to contain FIREFOX.EXE even after I change the default to Chrome.

Nice talking with you too!

But I still cannot set the home page!

Any advice?

Many thanks Taffy,

the website gives lots of useful info, and is very helpful. Thanks for answering.

I use Firefox as my browser, but sometimes use Edge 41 on Windows 10, and am unable to set Google there as my home page.

Any advice?

Best wishes,

Yes. The default browser is a 'per user' choice, you can look at the ProgId value in...
HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice

...but don't try changing it. When you change your default browser in Settings Hash (the other value you'll find there) changes too. This is presumably for protection against malware trying to change this key.

 

That will work. Thanks.

I don't want to change it. I just want to be able to programmatically determine what it is.

 

It's by checking HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice
But that was already told, so that's fine. But actually, determining and manipulating the default browser in Windows 10 is possible without using the registry, with Edge, it can be done through the Start menu. At least it has some use.
