When comparing MS-DOS vs Windows, the Slant community recommends Windows for most people. In the question“What is the most versatile operating system to learn how to program?” Windows is ranked 4th while MS-DOS is ranked 7th. The most important reason people chose Windows is:
No other OS comes close to supporting as much hardware as Windows 10 does. Because it's the most popular OS, the bulk of hardware manufacturers support Windows first, and all other operating systems second.

Ranked in these QuestionsQuestion Ranking
Pros
Pro Use old editor Edit
The grandfather of Notepad, very easy to use, hassle-free text editor.
Pro Brings back memories to older developers
Pro Best OS to run QBASIC on
While QBASIC works on newer operating systems, such as Windows 95 and Windows 98, it was designed for and runs best on MS-DOS.
Pro Best driver support of any OS
No other OS comes close to supporting as much hardware as Windows 10 does. Because it's the most popular OS, the bulk of hardware manufacturers support Windows first, and all other operating systems second.
Pro Widely used
Windows is the most-used desktop OS in the world.
Pro Windows comes first
Windows is the most used platform in the world. If you build something and need a third-party software it will most likely run on Windows. Not because it's good, but because everyone uses it.
Pro Free access to great development IDE in Visual Studio Community
Pro Ubuntu bash shell
Windows has a binary compatible Ubuntu shell to run non-Windows apps natively.

Pro Stable
Pro The most solid choice for .NET development
Pro Free with most new computers
At least the non-Apple variety at any rate.
Pro Touch screen support
You still can't get touch support on a Mac. Windows has had touch for 5+ years now.
Pro Best support for Visual Basic
Cons
Con Not a modern OS
If you need to know how to run legacy software that will run on DOS (crazier things have happened, there's probably still some ancient, leviathan, software out there that requires it), go for it. Otherwise you're practicing skills that are out of date and are using an operating system that is woefully insecure.
Con Literally horrible
MS-DOS is terrible -- just read about real mode. It was an almost decent solution for its time, but not anymore.
Con Way too simple
A stripped down version of Unix, some commands just got renamed and advanced options removed.
Con Dead
Ended in the 21st century.
Con No internet support
Using Internet with MS-DOS is not trivial.
Con Uses more resources than most alternatives
Con Most software is closed source, including the operating system itself
Con Weak default terminal
The standard terminal lacks basic features that Linux and OSX has. Alternatives to the default terminal for Window can be found here.
Con Lacks package management
It is not easy to install/keep current development packages that developers need and use.
Con Limited in its flexibility
Window managers, startup systems, and system components cannot be changed.
Con There are some privacy issues
By definition, it's spyware. Pre-compromised OS.
Con Scanning for viruses makes builds slow
Compiling a project means reading and writing a lot of files. Even fast anti-virus software slows down the build time (which is almost always too long).
Con Update policy / scheduling is a nightmare
Pop-up to update your system that will restart it if you don't interact quick enough and will have to be in reboot mode, which can freeze your activity until the update is done.
Con Unstable and slow
Windows crashes often and is much slower than alternatives, especially at file IO, which is important for developers.
Con Maintenance is time-consuming
Previous versions needed to be formatted ever 6 months to maintain performance.
Con Embarrassing to give talks
On conferences or in user groups the audience laugh at speakers presenting their talk on a Windows machine.
