Creating an image
To create a Windows Embedded 8.1 Industry image for an HP t520, t620, or t620 PLUS:
Note
The procedure below assumes you will log on to Windows as an administrator each time a Windows logon is required. For
more information about logon, software installation, and enabling or disabling UWF as required in this procedure, see the
Administrator Guide for Windows Embedded 8.1 Industry Pro on HP Thin Clients.
1. Install the base operating system on the thin client.
2. Install the HP driver pack (see Hardware-enabling drivers
).
3. Disable UWF, which requires a restart of the thin client.
4. After the restart, install the desired software programs, and then restart the thin client again.
5. Run each of the following commands in Command Prompt (Admin):
• C:\Windows\Microsoft.NET\Framework\v4.0.30319\ngen.exe executequeueditems
• C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen.exe executeQueuedItems
Important
The Ngen.exe process must complete before you proceed to the next step. If the process does not complete, newly-
installed .NET programs, such as HP Easy Shell, will always have a delayed startup time due to .NET elements being
recompiled every time the program starts.
6. Enable UWF, which requires a restart of the thin client.
To install additional software in the future, repeat steps 3–6 above.
