If you’re on a very old version of Windows, you may be able to update to Windows 10 instead and enjoy the final 12 months of official support. Microsoft goes on to recommend using its cloud storage subscription-based service OneDrive to migrate your data to a new computer.

Microsoft elaborates: “Windows 11 is the most current version of Windows. If you have an older PC, we recommend you move to Windows 11 by buying a new PC. Hardware and software have improved a lot, and today’s computers are faster, more powerful, and more secure.”

At least those 900 million Windows 10 users have another year before support ends—absent a surprise Microsoft support extension, an affordable support package or a workable workaround. But for 50-million Windows users that end of support nightmare has come true, and Microsoft is warning them of the consequences.
