The minimal hardware requirements and recommendations that Windows Thin Client must have are provided in the following subsections.
- RAM:The Windows Thin Client system software and the Microsoft RDP client together require at least 6 MB of RAM. This requirement does not reflect the amount of RAM that is required for the video frame buffer or the OEM-supplied software. This memory requirement supports a Windows Thin Client that is running one or two RDP sessions.
- Nonvolatile memory: The Windows Thin Client requires sufficient nonvolatile memory, such as flash memory or nonvolatile RAM, to store the universally unique identifier (UUID) and Windows Thin Client configuration settings. The UUID requires 128 bytes of memory. The amount of memory that is required to store the configuration settings, which is the registry, depends on the device, the software that is installed, and the number of Windows Thin Client connections that are defined. A typical Windows Thin Client device that has the RDP client installed and that has five connections defined requires approximately 20 KB of storage.
Microsoft recommends that you provide sufficient nonvolatile memory for the registry to grow to at least 50 KB in size.
