Not to be confused with Windows.
WinDOS is an operating system built on MS-DOS 9.0, originally released in 2000. It is the successor to MS-DOS. (as support for MS-DOS ended in 2001) It has a hybrid kernel containing mostly DOS and some Windows NT code. It builds on MS-DOS with things such as a graphical Windows Preinstallation Environment-like interface, support for Windows NT applications, long filenames, 2 terabytes of storage, and multiple user accounts. It also contains basic applications from Windows including:
- Notepad (notepad.exe)
- WordPad (write.exe or wordpad.exe)
- Paint (mspaint.exe)
- Control Panel (control.exe and .cpl files, relies on File Explorer)
- File Explorer (explorer.exe, can also be used as a basic GUI)
- About (winver.exe)
- Setup (setup.iso)
- Minesweeper (mines.exe)
- WD Basic (a version of Visual Basic) (wdb.exe)
- Internet Explorer for WinDOS (iexplore.exe, removed in 11.0)
- Microsoft Edge for WinDOS (msedge.exe, added in 11.0 to replace IE)
- Simple FTP (a basic FTP client) (sftp.exe)
- Microsoft Antivirus (antivirus.exe)
At startup, it starts at Command Prompt. WinDOS still has a DOS (disk operating system) functionality, as it is small enough to fit on a floppy disk or CD. It is mainly popular among businesses and people who still have older computers from the 1980s and 1990s.
WinDOS is sold as the default operating system on some business-geared computers. It is also compatible with netbooks, low-end to mid-range laptops and even tablets, however not installed by default.
Problems[]
One of Microsoft's goals was to make WinDOS's Setup files small enough to fit on a modern floppy disk. However the Windows code and features adds a lot of file size. WinDOS 10.0's media is about a gigabyte in size. It's recommended you put it on an optical disk.
The higher quality graphics could not run on some older PCs, so they sometimes had to be limited to 16 colors. For this, extra bitmap and PNG files with an imperior palette were included in C:\Windows\System32\interface.dll (not in Windows).
