Windows 10 Extended Security Updates (ESU) can provide security updates for eligible devices for a limited period. Check current Microsoft eligibility and enrollment terms before relying on it.
Protect your files first
Back up important files when possible. If the drive is encrypted, locate the BitLocker recovery key before recovery changes. Stop if storage appears to be failing or this is a work or school managed PC.
What ESU covers
ESU is a security-update option; it does not turn Windows 10 into a newly supported feature platform or fix existing hardware failures. Microsoft’s consumer guidance states coverage can extend through Oct. 12, 2027 for eligible devices.
What to check
Verify the Windows 10 edition and build, whether the device is consumer or organization managed, the current enrollment path, and your backup before choosing an update or upgrade.
Keep track of your checks
