Microsoft's support for Windows 10 is set to end on October 14, leaving approximately 400 million users without critical security updates unless they enroll in the Extended Security Update (ESU) program or upgrade to Windows 11. Currently, 41% of all PCs are running Windows 10, which translates to nearly 600 million devices, but many older PCs cannot upgrade due to hardware requirements. In contrast, when support for Windows 8 ended, only 3.7% of users remained on that platform. The cybersecurity community warns that the lack of updates will make many systems vulnerable to exploitation. Additionally, there has been an increase in Windows 7 usage, with nearly 140 million PCs still operating on that retired OS. Reports indicate a growing demand for an extension of Windows 10 support, particularly in regions outside Europe where the ESU program is not accessible.
