  • Article

The information in this specification is applicable to the following Microsoft products or supplemental software. References to product versions include updates to those products.

 

  • 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

  • Windows Server operating system

  • Windows Server 2019 operating system

  • Windows Server 2022 operating system 

  • Windows 11 operating system

  • Windows Server 2025 operating system

Exceptions, if any, are noted in this section. If an update version, service pack or Knowledge Base (KB) number appears with a product name, the behavior changed in that update. The new behavior also applies to subsequent updates 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 2.1:  An FCIADS stream is limited to 4 KB in length.

<2> Section 2.1:  An ADS stream containing these structures always sets the ADSCache_PropertyFlagsValid flag if it is generated on Windows 8 operating system and later, Windows Server 2012 operating system and later. An ADS stream generated on Windows Server 2008 R2 never sets this flag.

<3> Section 2.3:  Only Windows 8 operating system and later, Windows Server 2012 operating system and later process Property Definition Instance ([MS-FSRM] section 3.2.1.6.5) ADM element instances with Property Definition Instance.Secure ADM attributes set to TRUE. Because these Property Definition Instance ADM element instances are stored in an ADSSecurePropertiesExtensionHeader (section 2.3) structure, which conforms to the layout of the ADSFieldExtensionHeader (section 2.2) structure, Windows Server 2008 R2 retains but does not act on them when manipulating an FCIADS stream.
