In Windows before Windows for Workgroups 3.11, running winver from DOS reported an embedded string in winver.exe. Windows also includes the setver command that is used to set the version number that the MS-DOS subsystem reports to a DOS program. [16] This command is not available on Windows XP 64-Bit Edition.

Furthermore, on a modern x86 system, BIOS calls can only be performed in Real mode, or Virtual 8086 mode. v8086 is not an option in Long mode. This means that a modern operating system, which operates in Protected mode (32 bit), or Long mode (64 bit
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).

Version 3.0.0, introduced in February 2015, added a 64-bit entry point, which can coexist with the previously defined 32-bit entry point. Version 3.4.0 was released in August 2020. [8] Version 3.5.0 was released in September 2021. [9] Version 3.6.0 was released in June 2022. [10] Version 3.7.0 was released in July 2023. [11]
This was done by widening the general-purpose registers to 32 bits and introducing the concepts of OperandSize and AddressSize – most instruction forms that would previously take 16-bit data arguments were given the ability to take 32-bit arguments by setting their OperandSize to 32 bits, and instructions that could take 16-bit address ...
The initial version of cmd.exe for Windows NT was developed by Therese Stowell. [6] Windows CE 2.11 was the first embedded Windows release to support a console and a Windows CE version of cmd.exe. [7] The ReactOS implementation of cmd.exe is derived from FreeCOM, the FreeDOS command line interpreter. [2]
cmd.exe in Windows NT 2000, 4DOS, 4OS2, 4NT, and a number of third-party solutions allow direct entry of environment variables from the command prompt. From at least Windows 2000, the set command allows for the evaluation of strings into variables, thus providing inter alia a means of performing integer arithmetic. [26]
