Windows Unified Write Filter (UWF)

Unified Write Filter (UWF) write protects files, folders or partitions to prevent corruption of data from sudden power loss and stops unauthorised modification of the system – once the user reboots the system, he or she is presented with a clean install.

Some benefits:

• Reduce wear on solid-state drives. You cannot use UWF to protect external removable drives, USB devices or flash drives.
• make read-only media appear to the OS as a writable volume

Limitations:

• fast startup needs to be disabled
