Microsoft revokes Windows 8's patch privileges today

Windows 8, Microsoft's 2012 flop, will be retired from all support today, putting the 48 million users who still run the three-year-old operating system in a spot: Upgrade or risk getting hacked.
After today, Microsoft will no longer provide security updates for Windows 8 -- or for IE10 and IE11, the company browsers that run on the OS -- and the company will not offer technical support for the operating system.
To continue to receive security updates, Windows 8 users must upgrade to Windows 8.
