Microsoft's Windows Update is failing in restricted network environments after the January 2026 optional non-security preview updates, leaving affected systems unable to download later updates and showing 0x80010002. The issue affects air-gapped and strictly firewalled environments, but Microsoft says it does not affect device integrity or installation. Administrators can work around the problem with Known Issue Rollback (KIR) group policies while Microsoft works on a fix.

    Microsoft discloses Windows Update failure in restricted networks

    Initial Disclosure

    Microsoft says Windows Update can fail in restricted network environments, including air-gapped systems and strictly firewalled networks, after installing the January 2026 optional non-security preview updates. Affected devices may show error code 0x80010002 when downloading updates through the Windows Update page under Settings, and Microsoft says the problem affects download operations rather than device integrity or the ability to install updates. Administrators can use Known Issue Rollback (KIR) group policies for supported Windows versions while Microsoft works on a fix.
