What Windows 10 EOS Means For Security
Bitdefender, Wednesday, October 29th, 2025
Microsoft officially abandoned support for most versions of Windows 10 on October 14, 2025. It will continue to offer Extended Security Updates (ESU) temporarily for Windows 10 version 22H2, but that support will eventually expire as well, and can be expensive to maintain.
This decision by Microsoft is significant because 40%-45% of Windows users globally still regularly use Windows 10. From a cybersecurity perspective, this poses a significant risk. By ending support for the OS, Microsoft will no longer provide key updates to close vulnerabilities and fix bugs in Windows 10. This creates an enticing target for threat actors who are always on the lookout for the lowest-hanging fruit.
