Microsoft has ended the third and final year of Windows 7 Extended Security Updates and is urging customers to migrate to Windows 11 on a new PC or buy Windows 10 if they can't or don't want to. Microsoft has offered SMB and enterprise customers paid-for Windows 7 ESU since ending free security updates for Windows 7 on January 14, 2020. It's offered the Windows 7 ESUs to businesses for up to three years and that period came to an end today, January 10 -- the date of the first Patch Tuesday of 2023. The same goes for the less widely adopted Windows 8.1, for which support also ends today. Microsoft is not offering an ESU program for Windows 8.1.
