<120> Section 3.1.4.14: Windows allows Receive messages to execute concurrently with Send messages.

<121> Section 3.1.4.14: Windows rejects processing new Command requests and replies with an error response until successfully returning a ReceiveResponse with a CommandState element, indicating that the command has terminated or succeeded.

<122> Section 3.1.4.14: On Windows, the streams STDOUT and STDERR always end by using the rsp:Stream/@End attribute.

<123> Section 3.1.4.14: Windows does not provide notification that a command is blocked while waiting for input stream content by returning a rsp:CommandState element with the <Status> element set to rsp:CommandState/Pending. The <Status> element of the rsp:CommandState element is only set to rsp:CommandState/Pending when the command is pending termination; the subsequent value of the <Status> element is always rsp:CommandState/Done.

<124> Section 3.1.4.15: Windows Server 2003 R2, Windows Vista SP1, Windows Server 2008, Windows 7, and Windows Server 2008 R2 do not implement the Disconnect message.

<125> Section 3.1.4.16: Windows Server 2003 R2, Windows Vista SP1, Windows Server 2008, Windows 7, and Windows Server 2008 R2 do not implement the Reconnect message.

<126> Section 3.1.4.17: Windows Server 2003 R2, Windows Vista SP1, Windows Server 2008, Windows 7, and Windows Server 2008 R2 do not implement the Connect message.

<127> Section 3.1.4.19: Windows Server 2003 R2, Windows Vista SP1, Windows Server 2008, Windows 7, and Windows Server 2008 R2 do not implement the End message.

<128> Section 3.1.4.20: Windows Server 2003 R2, Windows Vista SP1, Windows Server 2008, Windows 7, and Windows Server 2008 R2 do not implement the Cancel message.

<129> Section 3.2.1: Client implementations on Windows 8 and later and Windows Server 2012 and later use a KeepAliveTimer interval of 42000 milliseconds if the request didn't specify a wsman:OperationTimeout SOAP header. If a wsman:OperationTimeout header was present in the request, the KeepAliveTimer interval is set to that value.

<130> Section 3.2.2: Client implementations on Windows 8 and later and Windows Server 2012 and later use a Connection KeepAlive Timer interval of (MaxPacketRetrievalTime - NetworkDelay), or 100 milliseconds if MaxPacketRetrievalTimeSeconds is less than NetworkDelay. MaxPacketRetrievalTimeSeconds is a server setting that is sent in the wsman:OperationTimeout SOAP header in messages the server sends to the client.

<131> Section 3.2.4.1.2: Windows implementations set the OperationTimeout value to 60 seconds unless overridden by the client application.

<132> Section 3.2.4.1.2: Windows implementations omit the OperationTimeout element by default, but include it if the client application explicitly specifies a value for it.

<133> Section 3.2.4.1.19: This SOAP header is not necessarily sent with every wst:Create message. Its inclusion is based on local configuration.

<134> Section 3.2.4.1.19: Windows Server 2003 R2 with KB968930, Windows Vista SP1 with KB968930, Windows Server 2008 with KB968930, Windows 7 and later, and Windows 8 and later clients send the CompressionType SOAP header as part of the wst:Create message with the value "xpress" to request the encoding according to the LZ77+Huffman compression algorithm described in [MS-XCA] section 3.2. Specifically, each stream block is encoded using the following algorithm:

The first 4 bytes represent the length of the original message -1 and the length of the compressed message – 1. Anything smaller than 266 bytes is not compressed.
If the size of the original data is 266 bytes or larger, the LZ77+Huffman algorithm is used to compress data.
If the total compressed size is more than input data/chunk, the data is written as-is. In this case, the original message length equals the compressed message length. Likewise, such an encoded block is read as-is (instead of processing through a decompressor).
The stream is compressed in 64 KB chunks; for example, a 100 KB input data is compressed in two separate blocks.

<135> Section 3.2.4.1.22.2: Web Services Management Protocol Extensions for Windows Vista clients are required to use an authentication scheme that is enabled.

<136> Section 3.2.4.1.23: Windows Server 2003 R2, Windows Vista SP1, Windows Server 2008, Windows 7, and Windows Server 2008 R2 do not send the wsmv:SessionId header in request messages.

<137> Section 3.2.4.2: Windows 8 and later and Windows Server 2012 and later include additional data in the ConnectType element for shells that are created using the PowerShell or PowerShell32 plug-ins, as specified in [MS-PSRP] section 3.1.4.10. That section also describes the content of the ConnectResponse element.

<138> Section 3.2.4.2.1: Windows Server 2003 R2, Windows Vista SP1, Windows Server 2008, Windows 7, and Windows Server 2008 R2 do not send the End and KeepAlive messages. Windows 8 and later and Windows Server 2012 and later do send the End and KeepAlive messages.

<139> Section 3.2.6.1: On Windows the network location of the event collector is configured by using Group Policy.

<140> Section 3.2.6.2: Windows 8 and later and Windows Server 2012 and later include additional information in the <ConnectType> element for shells that are created using the PowerShell or PowerShell32 plug-ins. The content included in the <ConnectType> element is specified in [MS-PSRP] (section 3.1.4.10).

<141> Section 3.2.7.8: Windows 8 and later and Windows Server 2012 and later include additional data in the ConnectType element for shells that are created using the PowerShell or PowerShell32 plug-ins, as described in [MS-PSRP] section 3.1.4.10. That section also describes the content of the ConnectResponse element.

<142> Section 5.1: The default security profile used by Windows is wsman:secprofile/https/spnego-kerberos.

<143> Section 5.1: Windows implements the following additional security profile: wsman:secprofile/https/mutual described in [DMTF-DSP0226] Annex C.3.5.
