Microsoft is rolling out a Windows 10 upgrade challenge wherein the company will give customers a Dell Inspiron 15 for free it it isn't able to upgrade your existing PC to its latest operating system on the same day. The caveat is that you'll have to take your PC to a Microsoft retail store.

If the PC meets all the hardware requirements for Windows 10, Microsoft's in-store Answer Desk experts will commence with the upgrade process. If they're unable to complete the upgrade to Windows 10 before the end of the business day, you'll receive a Dell Inspiron 15 gratis.


From Microsoft:

Free PC offer only valid for customers that have (1) one eligible PC that meets Window 10 upgrade requirements, (2) the eligible PC must be checked into the Answer Desk at participating retail store before 12 noon local time, and (3) the participating retail store cannot complete a customer's Windows 10 upgrade on an eligible PC within the same business day during regular store hours.

Got a notebook or PC running Windows 8.1 or Windows 7? Head to your nearest Microsoft retail store to participate in the Windows 10 upgrade challenge.
