Support for Windows Embedded 8.1 Industry on the HP t520, HP t620, and HP t620 PLUS Thin Clients

2
Overview
The purpose of this whitepaper is to outline HP support for Windows® Embedded 8.1 Industry on the HP t520, HP t620, and
HP t620 PLUS thin clients.
Windows Embedded 8.1 Industry Pro is not offered on the HP t520, HP t620, or HP t620 PLUS out of the factory. HP does
support Windows Embedded 8.1 Industry on these platforms if you upgrade to this operating system on these thin clients.
This configuration receives the standard 90 days of HP software support.
Therefore, you can purchase an operating system upgrade from Microsoft® or an authorized Microsoft reseller and enroll
the device in Volume Licensing and Software Assurance programs. Customers running a qualified Windows operating
system can purchase either the Windows Embedded 8.1 Industry Pro upgrade or the Windows Embedded 8.1 Industry
Enterprise upgrade. These upgrades give you access to the base operating system image so you can create your own
custom image. There are a number of changes required when transitioning from OEM to Volume Licensing, so it is important
to discuss these with the appropriate Microsoft representative or reseller before upgrading your operating system.
HP support for Windows Embedded 8.1 Industry
HP will support customers running either Windows Embedded 8.1 Industry Pro or Windows Embedded 8.1 Industry
Enterprise on their HP t520, t620, or t620 PLUS under the following conditions:
• The operating system must be the latest 64-bit version.
• The desired language is English, Norwegian, Spanish, French, German, Dutch, Arabic, Russian, Simplified Chinese,
Traditional Chinese, Korean, or Japanese.
• The upgrade was purchased from Microsoft or an authorized Microsoft reseller.
• The hardware-enabling drivers that were tested by HP are installed and used on the device.
• The flash and SDRAM memory minimum requirements are met. See Flash storage and memory.
Note
If the flash or SDRAM memory are not genuine HP parts, HP will not support or warranty issues with the third-party
parts.
• Unified Write Filter (UWF) is enabled at all times, except when the Administrator is configuring the system or the system
has been configured with an appropriate-size flash memory device to support large amounts of write/erase actions.
• No Windows Page File exists on the system.
Note
If the above conditions are not met, HP cannot provide support and your system could experience symptoms such as slow
performance, premature wear on the flash module, or other system integrity issues.
To help expedite your support process if your Windows Embedded 8.1 Industry installation has been customized in any way,
HP recommends that you duplicate the symptoms using the standard Windows Embedded 8.1 Industry image with only the
HP driver pack installed (no customizations) and then contact support.
Hardware-enabling drivers
The HP hardware-enabling drivers for Windows Embedded 8.1 Industry can be found on the HP t520, HP t620, and HP t620
PLUS product support pages bundled as a single driver pack. The driver pack contains all the necessary hardware-enabling
drivers along with two other software components: HP RAMDisk Manager and the HP Unified Write Filter Configuration
utility. This software is fundamental to delivering the HP thin client experience.
HP RAMDisk Manager enables the easy configuration of the RAM drive (by default, drive Z:). The RAM drive is volatile
memory, or a virtual drive created from the system's physical RAM. This drive looks and behaves like a standard fixed disk
drive, but is created at system startup and eliminated at system shutdown. HP recommends that you do not store
information or data on this virtual disk drive.
