Windows 1.0/COMDEX 1983
The user interface has changed significantly since the previous version shown in the BYTE Magazine December 1983 issue.
The session-control layer has since been removed and various other parts of the user interface have been restructured. Controls for each application are now shown in separate windows rather than a fixed area of the screen, making general usability far more convenient for users.
Other changes since the previous version include the use of window alerts at the top of the screen. These can display information pertaining to a particular program that is currently running; for example, selecting the "Time and Date" option in the Clock program menu will display the date and time at the top of the screen.
Since the removal of the session-control layer, minimized applications can also reside as icons in the bottom of the screen area. This allows for easier switching between currently running tasks.
One major change since the previous version is the introduction of Windows applications for use on a daily basis. These include a graphics viewer, the "Text" editor for opening text files, and early versions of Clock and Calendar.
MS-DOS application support
The MS-DOS command interpreter (COMMAND.COM) and all other MS-DOS-based applications can be accessed from the "MS-DOS 2.0 Window". Note that Windows allows for co-operative multitasking of both MS-DOS and Windows-based applications. Much like with PC-DOS and MS-DOS, file management was done from the same "MS-DOS 2.0 Window" which acted as a replacement for COMMAND.COM in Microsoft Windows.
