The new Surface Laptop comes loaded up with Windows 10 S by default, but it turns out early adopters will be able to upgrade to Windows 10 Pro for free. Specifically, anyone who picks up a Surface Laptop between now and December 31 can freely upgrade to Windows 10 Pro, a process that normally carries a fee.

Surface Laptop buyers can upgrade to Windows 10 Pro for free through December

The free upgrade is curiously mentioned on the Surface Laptop tech specs page, which states:

Prefer to run non-Store apps? Easily switch to Windows 10 Pro for free until Dec 31, 2017. Introductory offer: Includes 1 year of Office 365 Personal

Given that Windows 10 S is locked to the Windows Store for its apps, this is good news for anyone who happens to need apps found outside of the Store. The upgrade fee will normally be $49.99, and students can go ahead and upgrade for free if they need to.

In any case, if the Surface Laptop has piqued your interest, you can pre-order one for yourself now.
