You got it. But none of what you say makes the Windows OS any better than it is and has been. 2013, and as it was in 1983, it is still a single user machine with a single file version file system, no batch processing facility, primitive command line shell, etc, etc. (I know the “workarounds”, no need to educate me.) Compare to what was available in 1983.
If you had said 2000 instead of 1983, I might agree with you to an extent.
I don’t know what you had in 1983, but my Toshiba notebook from 2013 running W8 bears no resemblance to my Toshiba laptop from 1983 running MSDOS, in terms of functionality.
Comparing DOS to NTVDM is absurd, without even mentioning PowerShell. One of the best new things in NTVDM is the innate ability to process lists in a FOR loop, making batch processing a cinch. Add to that the ability to use (and the improvement in) jscript, vbscript, and wscript (again, not even mentioning PowerShell), and there is no comparison whatsoever.
