Overview
- Microsoft released KB5071959 via Windows Update to restore the Extended Security Updates setup flow on consumer Windows 10 PCs that could not enroll.
- Affected users are instructed to install KB5071959, restart, then run the Extended Security Updates wizard to activate ESU and resume receiving monthly patches.
- The update addresses reported errors such as regional unavailability messages in parts of the EU and generic registration failures like “something went wrong.”
- KB5071959 was delivered alongside November Patch Tuesday fixes and is documented as cumulative through October 14, 2025, with availability limited to devices not already registered for ESU.
- Microsoft frames this as a one‑time transition aid for consumers, with future security updates requiring ESU enrollment; outlets also note a free troubleshooting tool for persistent cases.
