5 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 NT 4.0 operating system

  • Windows 2000 operating system

  • Windows XP operating system

  • Windows Server 2003 operating system

  • Windows Vista operating system

  • 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

  • Windows 10 operating system

  • Windows Server 2016 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 2.5: Windows presents properties with PropertySet VT_LPSTR (0x001E) to applications as null-terminated string values such that the application cannot reliably detect the presence of trailing null characters or any characters following the first embedded null character. Properties with PropertyType VT_BSTR (0x0008) are presented to the application as a value of type BSTR (for more information, see [MS-DTYP] section 2.2.5), which is an explicitly-sized string type, and in which an application can detect these characters. Identical behavior also applies to scalar values of type VT_LPSTR or VT_BSTR, respectively, when these values are part of a vector or array property type.

<2> Section 2.18.2: Windows enables applications creating a property set to select whether a property set is Unicode, in which case the CodePage property is CP_WINUNICODE (0x04B0). Alternatively, it can select ANSI, in which case the CodePage property is the current ANSI code page identifier for the system.

<3> Section 2.18.3: Windows always selects the current user's default locale for the Locale property.

<4> Section 2.21: Different versions of Windows limit the size of a PropertySetStream packet as follows.
