As we have reminded our readers multiple times in the past few months, Windows 7 is set to expire this week. Microsoft will stop supporting this user favourite desktop operating system after tomorrow.

Microsoft says that starting January 15, 2020, a full-screen notification will appear to alert Windows 7 users of "the risk of continuing to use Windows 7 Service Pack 1 after it reaches end of support on January 14, 2020."
