* ''Threaded DPC'' [https://web.archive.org/web/20090424065603/http://msdn.microsoft.com/en-us/library/ms795178.aspx], conversely to an ordinary DPC (Deferred Procedure Call), decreases the system latency improving the performance of time-sensitive applications, such as audio or video playback.

* Data Redirection: Also known as ''data virtualization'', this virtualizes the [[Windows Registry|registry]] and certain parts of the file system for applications running in the [[Principle of least privilege|protected user context]] if [[User Account Control]] is turned on, enabling legacy applications to run in non-administrator accounts. It automatically creates private copies of files that an application can use when it does not have permission to access the original files. This facilitates stronger file security and helps applications not written with the [[least user access]] principle in mind to run under stronger restrictions. ''Registry virtualization'' isolates write operations that have a global impact to a per-user ___location. Reads and writes in the <tt>HKLM\Software</tt> section of the [[Windows Registry|Registry]] by user-mode applications while running as a standard user, as well as to folders such as "Program Files", are "redirected" to the user's profile. The process of reading and writing on the profile data and not on the application-intended ___location is completely transparent to the application.

* Windows Vista supports the [[PCI Express]] 1.1 specification, including extendedPCI configurationExpress Native spaceControl and segmentation[[Active State Power Management|ASPM]]. PCI Express registers, including capability registers, are supported, along with save and restore of configuration data.<ref>{{Cite web|title=Active State Power Management in Windows Vista|url=https://studylib.net/doc/7453014/active-state-power-management-in-windows-vista|access-date=2021-03-19|website=studylib.net|language=en}}</ref>

* Native support and generic driver for [[Advanced Host Controller Interface]] (AHCI) specification for [[Serial ATA]] drives, SATA [[Native Command Queuing]], [[Hot swapping|Hot plugging]], and AHCI Link Power Management.

* Full support for the [[Advanced Configuration and Power Interface|ACPI]] 2.0 specification, and parts of ACPI 3.0.<ref name="kernelfeatures">[http://download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/kernel-en.doc Windows NT 6.x Kernel Changes].
