Use EWF with Registry Filter (Standard 7 SP1)
7/8/2014
Using EWF or FBWF with Registry Filter lets you persist specific registry keys while protecting the rest of the operating system.
Warning
You must not use Registry Filter when HORM is active because once HORM is activated it requires the underlying disk to remain unmodified. Registry Filter commits its RamDisk contents to disk whenever a key it protects changes. This causes changes to the underlying disk and can cause file system corruption. To disable HORM, type ewfmgr -all -deactivatehorm then restart the system.
