About UWF (Unified Write Filter)
Before getting started on client configuration through the Atrust Client Setup console or through the Windows
Embedded Standard operating system, please note that in a session any changes to the system will not be kept by
default after the system restart. This is due to a special feature called UWF (Unified Write Filter) in your Windows
Embedded-based system.
By default, your mt180W is UWF-enabled. Unified Write Filter (UWF) is a sector-based write filter intercepting all
write attempts to a protected volume and redirecting those write attempts to a virtual overlay. With UWF, all system
changes will only affect the session where the changes are made. After restart, all changes will be discarded.
You can change the default via the Atrust Client Setup console. It’s strongly recommended that you read the related
section in this user’s manual first before making any changes to your system.
WARNING
•
Please read the following section
FIRST
before making any changes to your system:
“4.2.9 Configuring UWF (Unified Write Filter)” on page 49.
NOTE
•
As a thin client device, your mt180W is mainly for access to remote or virtual
desktops on servers. With the limited and protected (UWF-enabled) hard disk space,
it’s
not
recommended to save data on your mt180W. Instead, you can use storage
spaces over remote / virtual desktops, removable storage devices, or networks.
•
In case that you need to copy a file to the protected volume, ensure that its size is
smaller than the free memory (overlay) space. Otherwise, your system may have
unexpected results or become unresponsive.
About Default User Accounts
There are two default user accounts for your Windows Embedded-based system: one is the standard, the other
administrative. The default credentials are shown as follows:
Type
Account Name
Password
Administrator
Administrator
Atrustadmin
Standard user
User
Atrustuser
NOTE
•
The passwords are case sensitive.
About the Behavior of System Startup
Every time when the system is started up, it will automatically log in to the Windows Embedded operating system
using the default standard user account as indicated in the preceding table about default user accounts.
