Microsoft will end support for Windows 10 on October 14, creating operational and financial challenges for users in the Middle East, particularly businesses. Windows 10 is widely used in the region, with Saudi Arabia at 53%, Oman at 57%, Egypt at 66%, and the UAE at 43%. Organizations that have invested in Windows 10 may face compliance and security risks due to the lack of critical updates post-deadline. Transitioning to Windows 11 can be a lengthy process for companies, requiring updates or replacements for millions of devices. Microsoft offers an extended security updates (ESU) service for a fee, which provides limited updates for up to three years but does not cover all vulnerabilities. The ESU program is intended to encourage organizations to adopt Windows 11, but rising costs may make it an unviable long-term solution for some. Businesses must carefully consider the costs of upgrading versus the risks of remaining on an unsupported operating system.
