Browser extension
An extension is quick to install and controls supported traffic from its browser. Other applications continue to use their normal network path.
Desktop application
A desktop VPN can create a system-wide tunnel for supported traffic from the operating system and installed applications.
Which should you choose?
Use the extension for lightweight browser privacy. Choose the Windows app when you need broader device coverage.
Practical reminder
A VPN is one privacy tool, not a substitute for account security, software updates, or careful online decisions.
