On November 10, 2026, PowerShell released versions 7.7.0 and 7.6.10, coinciding with the end of support for versions 7.4 and 7.5. The new stable version, 7.7.0, is built on .NET 11 and introduces time-sortable UUIDs with the New-Guid command, while 7.6.10 is a minor patch on .NET 10 with support lasting until November 14, 2028. Users are encouraged to migrate from the unsupported versions to one of the new releases, as neither contains critical vulnerabilities but provide significant updates. Additionally, the shift from the MSI installer to MSIX may affect deployment for organizations relying on certain management systems, necessitating users to verify scripts against the breaking changes in 7.7.0 before broad rollout

PowerShell 7.7.0 and 7.6.10 Release as 7.4 and 7.5 Lose Support

PowerShell shipped 7.7.0 and 7.6.10 on November 10, 2026, minutes apart, the very day 7.4 LTS and 7.5 hit end-of-support. 7.7.0 is the new stable line built on .NET 11, while 7.6.10 is a small LTS servicing patch on .NET 10 that stays supported until November 14, 2028. The headline change is New-Guid now emitting time-sortable UUID v7, and the MSI installer is gone in favor of MSIX. Neither release carries a CVE, but admins on 7.4 or 7.5 should migrate now to a supported build.
