Registry filtering
Caution
The UWF component by Microsoft provides registry-filtering functionality, which includes the ability to add registry keys to a
registry exclusion list and to commit individual registry keys. However, documentation about the registry filter is limited, and
due to the complexity of Windows, dependencies are not always clear. Although the HP Unified Write Filter Configuration
app provides easy access to the registry exclusion list, HP does NOT support or recommend using the registry filtering
capabilities of UWF. Usage of this functionality is at your own risk.
