I don't need to watch the video to know that two of these options were entries in CONFIG.SYS, one of them "SWITCHAR" as I recall. It would cause DOS to use forward slash instead of backslash for separating components of a pathname, and it would use hyphens instead of forward slashes for command line options, both just like Unix.

Microsoft did have a reason to remove these features: compatibility with batch files. "\dev\" actually remained special in all later versions, in that it can always be used to open a device, even if that directory doesn't exist. This could break a common idiom in batch files to test if a path is valid: C:\> if exist \dev\nul echo Yup, still there (I don't have a recent version of Windows to test this on, interested to see if it still works!)
