Since January 10, 2023, Microsoft has patched hundreds of "Zero-Day" vulnerabilities in Windows 10 and 11 (the current operating systems). Windows 8.1 gets none of these patches. For example, in January 2026 alone, Microsoft patched CVE-2026-20805, an information disclosure zero-day in the Desktop Window Manager that was actively being exploited in the wild. If you are on Windows 8.1, you are vulnerable to such exploits—and they are being found and weaponized every month.
