Google Chrome is fast and highly customizable – the ideal general-purpose web browser for your new PC

General web browser: Chrome

New Windows PCs come with Microsoft Edge installed as the default browser. It’s fast, integrates fully with Windows 10 (including Cortana), and is pleasant to use. It also supports extensions, but if flexibility is your main priority then you’ll want to consider an alternative.

Google Chrome supports hundreds of plug-ins, and is the natural choice if you’re already invested in the Google ecosystem through its web apps or an Android smartphone. If you’ve been using Chrome on your old PC, all your bookmarks, cached logins, extensions and browser history will be synced automatically when you log in.

It’s incredibly convenient, and a great browser for your new PC if you don’t mind the search giant having so much control over your online life.

Secure web browser: Tor Browser

If security is the name of the game, consider installing Tor Browser on your new PC. This is a modified version of Firefox that protects your identity and personal information by redirecting web traffic through a series of encrypted notes scattered throughout the world. This prevents your activity being monitored, prevents information like bank details being intercepted, and conceals your location.
