1 fonte(s) · 1 atualização(ões) · publicado 13/11/2026 01:19 · coletado há 1 hora

The Windows 11 cumulative security update KB5132061, targeting versions 24H2, 25H2, and 26H2, caused widespread installation failures shortly after release. Users experienced installation stalls at 99% with various error codes (e.g., 0x800f0993, 0x80070306) linked to conflicts with Windows Sandbox components. Microsoft quickly diagnosed the issue and deployed a server-side fix to resolve the problem, allowing automatic recovery within 24 to 48 hours without user intervention. Administrators can also manually install the update to expedite remediation. Temporarily disabling Windows Sandbox offers a manual workaround for affected users.
