The "It's now safe to power off the system" screen in Windows 10 and 11. Microsoft's Windows 98 was the first operating system to implement ACPI, [17] [18] but its implementation was somewhat buggy or incomplete, [19] [20] although some of the problems associated with it were caused by the first-generation ACPI hardware.

The first-generation Intel APIC chip, the 82489DX, which was meant to be used with Intel 80486 and early Pentium processors, is actually an external local and I/O APIC in one circuit. The Intel MP 1.4 specification refers to it as "discrete APIC" in contrast with the "integrated APIC" found in most of the Pentium processors. [2]
Advanced power management (APM) is a technical standard for power management developed by Intel and Microsoft and released in 1992 [1] which enables an operating system running an IBM-compatible personal computer to work with the BIOS (part of the computer's firmware) to achieve power management.
WMI extensions for WDM offer a set of Windows device driver interfaces for instrumenting data within the driver models native to Windows, so OEMs and IHVs can easily extend the instrumented data set and add value to a hardware/software solution. The WMI Driver Extensions, however, are not supported by Windows Vista and later operating systems. [11]
Windows XP, when fitted with the latest hardware abstraction layer (HAL), can also use the processor's Time Stamp Counter (TSC), or ACPI Power Management Timer (ACPI PMTIMER), together with the RTC to provide operating system features that would, in later Windows versions, be provided by the HPET hardware. Confusingly, such Windows XP systems ...
Device drivers that have passed the WHQL tests are also made available for download using Windows Update or the Microsoft Update Catalog. Not all of the drivers in Windows Update are up to date. On Windows XP, when Windows detects a new device for which it does not have built-in drivers, it shows a Found New Hardware Wizard dialog box ...

The Microsoft Windows Driver Model unified driver models for the Windows 9x and Windows NT product lines by standardizing requirements and reducing the amount of code that needed to be written. WDM drivers will not run on operating systems earlier than Windows 98 or Windows 2000, such as Windows 95 (before the OSR2 update that sideloads the WDM ...
