The command is available in MS-DOS versions 2 (1983) and later. [5] While the ultimate origins of using the three-character string CLS as the command to clear the screen likely predate Microsoft's use, this command was present before its MS-DOS usage, in the embedded ROM BASIC dialects Microsoft wrote for early 8-bit microcomputers (such as TRS-80 Color BASIC), where it served the same purpose.
The operating system never clears the archive bit unless explicitly told to do so by the user. Even when a user explicitly tells the operating system to copy a file for the purpose of archiving it, the archive bit will still not be cleared. A specific command for clearing or setting the bit must be executed.
TCC is based on the earlier 4DOS command shell for DOS, and 4OS2 for OS/2. [4]Beginning with version 12 of 4NT, support for Windows 95, 98, ME, NT and 2000 were removed. Beginning with version 16 of TCC, support for Windows XP was removed, [1] although it might still run in XP. 4NT was renamed to Take Command Console as part of JP Software's Take Command versi
Windows Vista uses Package Manager (Pkgmgr.exe) and Windows Update Standalone Installer (Wusa.exe) to install software updates and hotfixes. However, these do not support the various command-line switches like Windows XP's Package Installer (Update.exe) did. [84] Much of the functionality from Update.exe is missing.
The 64-bit versions of Vista require that all new Kernel-Mode device drivers be digitally signed, so that the creator of the driver can be identified. [77] [78] This is also on par with one of the primary goals of Vista to move code out of kernel-mode into user-mode drivers, with another example bing the new Windows Display Driver Model. [79]
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]

The text mode is unavailable in Windows Vista and later. Starting with Windows 10, however, a native full-screen mode is available.
