A plastic-cleaning agent applied to the surface of the keys with a cloth is used to remove the accumulation of oil and dirt from repeated contact with a user's fingertips. If this is not sufficient for a more severely dirty keyboard, keys are physically removed for more focused individual cleaning, or for better access to the area beneath.
Disk Cleanup (cleanmgr.exe) is a computer maintenance utility included in Microsoft Windows designed to free up disk space. It was introduced in Windows 98 and has been a part of Microsoft Windows ever since.
A registry cleaner is a class of utility software designed for the Microsoft Windows operating system, whose purpose is to remove redundant items from the Windows Registry. Registry cleaners seem to no longer be supported by Microsoft, despite originally having made and distributed their own registry cleaner under the name of RegClean.
CPU-Z is more comprehensive in virtually all areas compared to the tools provided in the Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate. It also provides information on the system's GPU.
The Windows Installer CleanUp Utility is a legacy software utility for the Microsoft Windows operating system designed to solve installation problems of apps that use the Windows Installer technology. An app whose Windows Installer entries are damaged cannot be uninstalled or reinstalled via the normal means.
However, most general-purpose systems use only two rings, even if the hardware they run on provides more CPU modes than that. For example, Windows 7 and Windows Server 2008 (and their predecessors) use only two rings, with ring 0 corresponding to kernel mode and ring 3 to user mode, [7] because earlier versions of Windows NT ran on processors ...
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.
In computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions ...
