For example, hardware timers send interrupts to the CPU at regular intervals. Most operating systems execute a HLT instruction when there is no immediate work to be done, putting the processor into an idle state. In Windows NT, for example, this instruction is run in the "System Idle Process". On x86 processors, the opcode of HLT is 0xF4.
Windows 2000 SP3 and Windows XP SP1 have added support for hyper-threading. Intel released the Nehalem microarchitecture (Core i7) in November 2008, in which hyper-threading made a return. The first generation Nehalem processors contained four physical cores and effectively scaled to eight threads.
Touch Keyboard: Windows 11 introduces thirteen new themes to customize the touch keyboard, including 3 hardware-matching themes that match the Surface keyboard colors. It also adds a new theme engine that allows the user to create a custom theme using background images. In addition, Windows 11 adds the ability to resize the touch keyboard.
Intel Unison is a software functionality created by Intel for seamless integration between a personal computer and mobile device. [ 1 ] Unison was announced in September 2022 and launched broadly throughout 2023 12th generation Core processors, although some Intel Evo compliant computers had a preview version of it already.

The Intel Atom, first released in 2008, is the first Intel product to feature 2-way SMT (marketed as Hyper-Threading) without supporting instruction reordering, speculative execution, or register renaming. Intel reintroduced Hyper-Threading with the Nehalem microarchitecture, after its absence on the Core microarchitecture.
Re-introduced the ability to display seconds in the system clock on the taskbar; Adds support for Bluetooth LE Audio and the LC3 codec; The fourth component update to Windows 11, version 22H2, codenamed "Moment 4", [7] was released on September 26, 2023, with build 22621.2361 and several further changes: [16] [17]
While early generations of CPUs carried out all the steps to execute an instruction sequentially, modern CPUs can do many things in parallel. As it is impossible to just keep doubling the speed of the clock, instruction pipelining and superscalar processor design have evolved so CPUs can use a variety of execution units in parallel - looking ahead through the incoming instructions in order to ...
