This is not a life or death question. Just pure curiosity that killed a cat. I am told by Microsoft experts that there is no DOS within Windows Me to use, that all DOS programs are caput. That's it and tough nuggies. To counter the above, I shall bring three examples of my own experience.
1/ I have purchased a very useful program called Winfix. While installing it and/or using it, it dives down into what it calls a monitor level and operates from there. Not to be fooled, one can see that it operates in DOS. Then it returns you to the Windows.
2/ I have received a printer roller cleaning kit from HP with a software program on floppy disk that conforms with Windows up to 95 version, where one is supposed to boot up in DOS and perform the task. You can not do this in Me version and at the beginning I was stuck. It will not operate from inside Win, nor it will work from the command window. After everything had failed, I read instructions, i.e. help file and found that I should click on DOS .exe file, go to Properties and check a small box, which says something like "tell Windows to disregard that this is a DOS program". After I have done that, I clicked on this file and, indeed, it performed my printer cleaning duties without any problems or bitching right from the Windows Me desktop.
3/ Being encouraged by the above, I tried my old, strictly DOS spreadsheet Supercalc 5 right from the desktop and without any adjustments. Works like a charm as it used to do from the DOS prompt.
Now I am confused. I definitely see that even Windows Me still has (maybe hidden) DOS elements within it and why would Microsoft experts mislead me here telling me that DOS is out? Anybody can give me a dissertation on this?
