By default, some of the cheapest Windows 10 notebooks, such as the Surface Go, start in Windows 10 S mode. This limited version of the OS doesn't let you run classic Windows applications and has various other restrictions. As a result, most users will watch to switch out of Windows 10 in S mode as soon as possible.

Thankfully, Windows 10 S isn't an entirely new OS. It's essentially Microsoft's latest operating system with some features unchecked to aid performance and security on low-end hardware. As a result, you can disable Windows 10 S mode very and move from Windows 10s to 10 Pro for free.

The process to disable S mode only takes a couple of minutes. However, it's worth noting that this is a one-way toggle – once you switch out of S mode there's no going back without a complete factory reinstall.

Windows 10 in S mode vs Windows 10 Pro

To help you decide, here are some of the differences between Windows 10 S and Windows 10 Pro:

Windows Store Apps	x	x
OneDrive setup and sync	x	x

Switching out of S mode gives you more control over your OS, but that comes with security and performance implications. You should only enable it if you need to perform a task or install an application that isn't otherwise supported. Let's get started with the tutorial:
