Following the end of Windows 10’s official support in October, many users have encountered challenges during the transition period. Although Microsoft introduced a one-year extension of free security updates, some customers have reported issues enrolling in the Extended Security Updates (ESU) program.
To address the issue, Microsoft has released a critical update, KB5071959, intended to resolve the enrollment failures. The out-of-band patch corrects a bug that caused the ESU enrollment wizard to crash, blocking users from signing up. Once applied, the update should restore normal functionality and allow affected users to complete enrollment and secure their systems.
According to reports, the error appeared differently based on location. EU users were told enrollment was “temporarily unavailable,” whereas users in other regions received a general error message. With KB5071959 now released, Microsoft has acknowledged the problem and provided a targeted fix.
One thing to keep in mind: this fix includes a Servicing Stack Update, which helps keep Windows Update running smoothly. Microsoft is sending it out with this month’s Patch Tuesday updates to anyone running into the enrollment problem. After you’re successfully enrolled, you’ll keep getting the important security updates you need.
If you’re planning ahead, Windows 10 will still get extended security updates until 2026. Businesses and schools that need more time can pay for ESU coverage through October 2028, and a few special cases may get support into 2032. And if that’s still not enough, some third-party companies are stepping in with their own security options.
