Google introduced Chrome Canary build two years back which is more of a nightly build gets updates daily. This release can be used along with any other installed Chrome channel such as dev./beta/stable. Chrome Canary will be installed in a separate directory and uses separate profile from other chrome version you’re running. Google doesn’t allows us to set Chrome Canary as default browser, it is highly unstable than dev. and can break often. But all new features will be first tested on Canary and then released to Dev. channel once successful. If you’re an early adopter and use Chrome Canary on daily basis, if you want to set Chrome canary as default browser here is how.
Making Chrome Canary as your default browser
1. All you need to do is download a simple registry file “CanaryAsDefault” from here in zip format and extract its contents to a folder. Right click on “Registry” file and select “Edit” to open in notepad, replace all occurrences of “YourUsernameHere ” with username given by you to Windows, (for example mine is venkat).
2. Save the changes to the registry file and close it. Now close all browsers if any opened. Run the registry file you just made the changes. You’ll get a warning from the registry editor, click “Yes” button.
3. Restart Windows Explorer or log off Windows and now try to open any other external link in applications like Word it will open in Chrome Canary.
After this change Chrome Canary settings page still shows the message that “this is a secondary installation of Google Chrome and can not be made your default browser” but it has been set as default one with registry hack we implemented successfully.
The registry file we used registers Chrome Canary as default handler for file types such as .html, .htm, .xhtml, .xhtm, and Internet shortcut files. Its working for us.
You can undo changes made to the registry by running uninstall registry file found in the CanaryAsDefault folder extracted earlier.
