How to Change Default Browser on Windows 10

Windows default browser assignment has become progressively more granular, meaning changing the "browser default" doesn't automatically redirect all web-related file types — you may also need to manually reassign .htm, .html, .pdf, and web URL protocols (http, https) to your preferred browser individually in Settings > Apps > Default Apps. Microsoft Edge often reasserts itself as the default for specific file types after major Windows updates, so it's worth double-checking after major OS upgrades. On Windows 11, the default browser can be set globally in Default Apps > search for your preferred browser and click the entry to reassign all associated protocols at once.
