The end of support for Windows 10, originally set for October 14, 2025, has been postponed for certain users, particularly accounting firms, allowing them more time to upgrade. Microsoft has introduced an Extended Security Updates program for select Windows 10 users, which requires a fee per device for continued security updates, but does not include new features or general tech support. A December 2023 report indicates that 47% of accountants still rely on Windows 10, with approximately 25% of Windows 10 PCs actively used in accounting firms. Over half of all devices have migrated to Windows 11, which holds about 52% of the market. Experts recommend delaying upgrades to Windows 11 in favor of Windows 12, expected to be more optimized for AI, with potential hardware investments needed for the transition.
