Users will no longer be able to upgrade to Windows 10 for free soon, with Microsoft’s initial offer set to expire 29 July.
Any users wanting to download the operating system will have to pay $179 for the home edition of Windows 10 in two months’ time.
Microsoft reminded customers on its blog about the offer expiration, along with news it has surpassed 300 million Windows 10 users since launching last year.
The software giant is preparing to release a Windows 10 anniversary update in the coming months for all Windows 10 users.
New features will include biometric security for Windows apps, more stylus functionality, and Cortana integration for more apps.
