6 Appendix A: Product Behavior

The information in this specification is applicable to the following Microsoft products or supplemental software. References to product versions include released service packs:

  • Windows XP operating system

  • Windows Vista operating system

  • Windows Vista operating system with Service Pack 1 (SP1)

  • Windows Server 2008 operating system

  • Windows 7 operating system

  • Windows Server 2008 R2 operating system

  • Windows 8 operating system

  • Windows Server 2012 operating system

  • Windows 8.1 operating system

  • Windows Server 2012 R2 operating system

Exceptions, if any, are noted below. If a service pack or Quick Fix Engineering (QFE) number appears with the product version, behavior changed in that service pack or QFE. The new behavior also applies to subsequent service packs of the product unless otherwise specified. If a product edition appears with the product version, behavior is different in that product edition.

Unless otherwise specified, any statement of optional behavior in this specification that is prescribed using the terms SHOULD or SHOULD NOT implies product behavior in accordance with the SHOULD or SHOULD NOT prescription. Unless otherwise specified, the term MAY implies that the product does not follow the prescription.

<1> Section 1.7: When the implementation is configured with Windows XP, the Network Access Protection (NAP) client must be installed.

<2> Section 2.2.6: The Windows client versions are as follows:

Value

Meaning

0x00050001

Windows XP WSHA

0x00060000

Windows Vista WSHA

0x00060001

Windows Vista SP1WSHA

<3> Section 2.2.7: This class is implemented in Windows Vista, Windows 7, Windows 8, and Windows 8.1. An SoH from a Windows XP client will not include the antispyware TLVs. Similarly, an SoHR back to a Windows XP client will not include the antispyware TLVs. The WSHV uses the Version field in the SoH to determine whether the client is a Windows XP, Windows Vista, Windows 7, Windows 8, or Windows 8.1 client. If it is from a Windows XP client, the WSHV will not expect any antispyware data to be present.

<4> Section 2.2.10: In Windows Vista, Windows 7, Windows 8, and Windows 8.1, the DurationSinceLastSynch TLV is updated only when the statement of health (SoH) has changed.

<5> Section 2.2.12: For Windows Vista clients, the field contains the maximum severity rating of the security updates that it knows about. For Windows XP, Windows Vista SP1, Windows 7, Windows 8, and Windows 8.1 clients, it also contains the security update source that the client is enlisted in.

<6> Section 3.1.1: Implemented in Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, and Windows Server 2012 R2. The WSHV on Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, and Windows Server 2012 R2 does not evaluate the flag value, and therefore, will process any SoH it receives, even if the flag is a duplicate of the flag in an SoH that was received earlier.

<7> Section 3.2.5.2: If the client is running on the Windows XP operating system, proceed to step 1-11 to continue with the initialization process; otherwise, proceed to the next step, step 1-8.

<8> Section 3.2.5.2: If the client is running on the Windows XP operating system, proceed to step 15 to continue with the initialization process; otherwise, proceed to the next step, step 12.

<9> Section 3.3.1: The policy for Windows XP clients is stored in the registry key path "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows System Health Validator\{51fecd48-263c-4ea2-b304-47a3b5136809}". The policy for all clients other than Windows XP is stored in the registry key path "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows System Health Validator\{d40a68da-831c-4ca3-a273-1ac569205353}". These registry keys are consumed by the WSHV.

<10> Section 3.3.1: The AntiSpywareScanEnabled ADM element is used only with Windows Vista, Windows 7, Windows 8, and Windows 8.1 clients.

<11> Section 3.3.1: The AntiSpywareUptoDate ADM element is used only with Windows Vista, Windows 7, Windows 8, and Windows 8.1 clients.

<12> Section 3.3.3: The AntiSpywareScanEnabled ADM element is used only with Windows Vista, Windows 7, Windows 8, and Windows 8.1 clients.

<13> Section 3.3.3: The AntiSpywareUptoDate ADM element is used only with Windows Vista, Windows 7, Windows 8, and Windows 8.1 clients.

<14> Section 3.3.5.2: If the value of SoH TLV 3 is 0x00050001 (indicating that the client is running on the Windows XP operating system), proceed to step 77 to continue with the initialization process; otherwise, proceed to the next step, step 50.

<15> Section 3.3.5.2: If the value of SoH TLV 3 is 0x00060000 (indicating that the client is running on the Windows Vista operating system) and HealthStatus is set to S_MSSHA_NO_MISSING_UPDATES, set MinSeverityRating to zero and proceed to step 111 to continue with the initialization process; otherwise, do not modify the value of MinSeverityRating and proceed to the next step, step 108.
