KB5071959: Microsoft fixes Windows 10 Extended Security Update enroll bug

Microsoft ended Windows 10 support with the final Patch Tuesday under KB5066791 last month on October 14, 2025. Following that today, the company has released the first Patch Tuesday as part of the Extended Security Updates (ESU), and as such, is labelled as out-of-band update.

Here is the summary of the update.

"This out-of-band (OOB) update is offered to consumer devices that are not enrolled in the Extended Security Updates (ESU) program for Windows 10. This update is cumulative and includes security fixes and improvements from the October 14, 2025, security update (KB5066791), in addition to the following:

• This update addresses an issue in the Windows 10 Consumer Extended Security Update (ESU) enrollment process, where the enrollment wizard may fail during enrollment. After applying this update, consumer devices should be able to successfully enroll in ESU using the ESU wizard.

Microsoft also notes that:

• Once enrollment is completed, your device will begin receiving Extended Security Updates via Windows Update.
• This update is marked as a security update for devices that are not enrolled in the Windows 10 consumer ESU as it resolves an issue that was preventing affected customers from receiving essential security updates.
