Windows Embedded Standard 7 for HP Thin Clients - Administrator Guide

Committing cached write data
For EWF, committing the volume overlay will make all changes made since the last thin client restart
become permanent after the next thin client restart.
For FBWF, individual files can be committed, and the action takes effect immediately.
CAUTION: Be sure to know what changes have been made since the last restart so that unwanted
changes are not committed.
The following table describes the different methods for committing cached write data.
Method 1 (EWF only) Method 2 Method 3
1. Right-click the write filter status
icon in the notification area and
select Commit EWF.
2. Restart the thin client.
1. Open the HP Write Filter
Configuration utility.
2. EWF: On the EWF Main tab, click
Commit Data to Volume, and then
restart the thin client.
FBWF: On the Cached File
Commit/Restore tab, select the
files you want to commit and click
Commit. The action takes effect
immediately.

TIP: For FBWF, individual cached files can be restored to their previous state (from the underlying volume) using either the
HP Write Filter Configuration utility or the command line.
Adding files and folders to the exclusion list (FBWF only)
Writes to files and folders in the exclusion list will not be intercepted by FBWF, meaning that the
changes are always permanent and do not require a thin client restart.
CAUTION: Keep this list to a minimum to decrease wear on the flash drive.
The following table describes the different methods for adding files and folders to the exclusion list.
Method 1 Method 2
1. Open the HP Write Filter Configuration utility.
2. Click the Exclusion List tab.
3. Click Add, and then specify the item to add to the
exclusion list.
4. Restart the thin client.
1. Use the command line to add files and folders to the
exclusion list.
2. Restart the thin client.
TIP: Files and folders can also be removed from the exclusion list using either the HP Write Filter Configuration utility or the
command line. A thin client restart is required for the removal to take effect.
The following table defines the icons that are used when the exclusion list is viewed in the HP Write
Filter Configuration utility.
