Unified Write Filter

    What it does:

    Unified Write Filter (UWF) is an optional Windows 10 feature that helps to protect your drives by intercepting and redirecting any writes to the drive (app installations, settings changes, saved data) to a virtual overlay. The virtual overlay is a temporary location that is usually cleared during a reboot or when a guest user logs off.

    Important

    When using ConfigMgr Remote Control and the Unified Write Filter, you may need to add a firewall rule to allow TCP2701 inbound.
