PageDefrag is a program, developed by Sysinternals (now distributed by Microsoft), for Microsoft Windows that runs at start-up to defragment the virtual memory page file, the registry files and the Event Viewer's logs (files such as AppEvent.Evt, SysEvent.Evt, SecEvent.Evt and so on).
The Windows Task Manager utility for Windows XP and Server 2003, in its Performance tab, shows three counters related to commit charge: . Total is the amount of pagefile-backed virtual address space in use, i.e., the current commit charge.
Windows 11 is the latest major release of the Windows NT operating system and the successor of Windows 10. Some features of the operating system were removed in comparison to Windows 10, and further changes in older features have occurred within subsequent feature updates to Windows 11. Following is a list of these.
A null pointer is usually represented as a pointer to address 0 in the address space; many operating systems set up the MMU to indicate that the page that contains that address is not in memory, and do not include that page in the virtual address space, so that attempts to read or write the memory referenced by a null pointer get an invalid ...
It is the smallest unit of data for memory management in an operating system that uses virtual memory. Similarly, a page frame is the smallest fixed-length contiguous block of physical memory into which memory pages are mapped by the operating system. [1] [2] [3]
However, the page file only expands when it has been filled, which, in its default configuration, is 150% of the total amount of physical memory. [16] Thus the total demand for page file-backed virtual memory must exceed 250% of the computer's physical memory before the page file will expand.

These include string manipulation, memory allocation, C-style input/output calls, and others. MSVCP*.DLL is the corresponding C++ library. It has shipped with Windows versions since Windows 95 OSR2.5 for use by other Windows components; earlier versions shipped with the CRTDLL.DLL library instead.
