That’s why Microsoft told Windows users to keep their devices updated with patched, secure versions of Windows 10, Windows 7, Windows 8.1, Vista, Windows Server 2008 or later versions. Most PCs that got hit by this cyber attack were on older Windows XP which is no longer officially supported by Microsoft.
