        An elevation of privilege vulnerability exists in Windows Setup in the way it handles directories.

        A locally authenticated attacker could run arbitrary code with elevated system privileges. After successfully exploiting the vulnerability, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

        The security update addresses the vulnerability by ensuring Windows Setup properly handles directories.

        PS. The bug only happens on Windows 10 upgrades, not clean installs.

        How do I know if I’m protected from this vulnerability?

        As of this date, all in-support Feature Update bundles have been refreshed with the patched Setup binaries, so this vulnerability no longer exists.

        If you are using WSUS or MEM ConfigMgr or another third-party management tool, please sync the latest feature update bundles and approve those for deployment. If you are using Windows media, as applicable to your system, please download the latest refreshed media from VLSC or Visual Studio Subscriptions (formerly MSDN), or download the latest applicable Setup Dynamic Update (DU) package and patch your existing media.
