A write filter provides a secure environment and can extend the life of a thin client by protecting it from unauthorized and excessive writes to the flash drive. Write data is intercepted by a write filter and cached in the RAM drive, and as a result, lost after the next thin client restart. There are two different write filters available: ● Enhanced Write Filter (EWF)—Protects an entire volume (C: by default) by caching all write data into an overlay ● File-Based Write Filter (FBWF)—Caches individual files, allowing you to specify files or folders to be excluding from protection (excluded files will always write to the underlying volume)
NOTE: EWF is enabled by default. Only one write filter can be used at a time.
In the Control Panel, click HP Write Filter Configuration. TIP: You can alternatively double-click the write filter status icon in the notification area. The tasks you can perform in this utility include the following: ● View information about the write filter currently in use ● Enable either EWF or FBWF, or disable both ● Commit cached write data from the volume overlay (EWF) or individual files (FBWF) ● Clear the current boot command

I understood the use of the write filters and why it is there.
What I would like to reach is to know the files and registry directories which are used to add a printer to add those paths in the filter. In that way, users would be able to add printer as persistent without the need of an administrator password.
Do you think that goal is possible ?
