Windows 7 and Windows 8.1 reach the end of the line

by
Ars reports: It’s the end of the line for Windows 7 and Windows 8.1. These older versions of Windows (plus Windows RT) stop receiving all security updates today, over a decade after their original releases. Microsoft will also stop providing Microsoft Edge browser updates for these operating systems in a few days, and the remaining third-party apps that still work will eventually follow suit (Google Chrome support, most notably, ends early next month). Windows 7 support for most people actually ended three years ago, but businesses that still used it could pay for up to three years of additional support while they transitioned to Windows 10 or 11. That window has now closed, and Microsoft isn’t offering a paid support option for Windows 8.1. Run an unspported operating system, or invite more ads and spyware. Tough call.
