The BIOS in some computers, when matched with operating systems such as some versions of Linux, BSD, and Windows (Windows 2000 and later [13]), allows counting of detected and corrected memory errors, in part to help identify failing memory modules before the problem becomes catastrophic.
Power-on self-test. A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [1] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
Serial presence detect. In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module. Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
EDAC is a Linux kernel subsystem that handles detection of ECC errors from memory controllers for most chipsets on i386 and x86_64 architectures. EDAC drivers for other architectures like arm also exists. It is recommended to use rasdaemon to gather MCE information on Linux systems because mcelog has been deprecated as of 2017.

Taskbar. The following taskbar features are no longer available as of Windows 11: Support for moving the taskbar to the top, left, or right of the screen [7] Support for changing the size of the taskbar or its icons. "Time" is not displayed in the calendar when clicking on the "Date/Time" on taskbar. Scheduled events are not displayed in the ...
Available for Windows 7 to 11, or Windows Server from 2008 R2 to 2022; 32/64-bit x86 or 64-bit ARM. SoftPerfect RAM Disk can access memory available to Windows, i.e. on 32-bit systems it is limited to the same 4 GB as the 32-bit Windows itself, otherwise for physical memory beyond 4 GB it must be installed on 64-bit Windows.
Thus, Windows 11 is the first consumer version of Windows not to support 32-bit processors (although Windows Server 2008 R2 is the first version of Windows Server to not support them). [153] [154] The minimum RAM and storage requirements were also increased; Windows 11 now requires at least 4 GB of RAM and 64 GB of storage. [155]
Software testers. Memory diagnostic software programs (e.g., memtest86) are low-cost or free tools used to check for memory failures on a PC. They are usually in the form of a bootable software distribution on a floppy disk or CD-ROM. The diagnostic tools provide memory test patterns which are able to test all system memory in a computer.
