"Windows Vista was the worst".....actually the worst was Windows ME..an OS that only lasted a few months before PC makers refused to pre-install it. One of only two times PC makers did this. (Windows 8 was the 2nd time when makers offered Win 7 as an option)
Windows now no longer offers an operating system for business use. Windows 10 simply doesn't work well at all for multiple networks and multiple hardware use. We have two PC's in the bldg with Win10 and both are a constant headache as they continuously drop printers/scanners and networked drives. This is the first time I can ever remember where people in the office pray their computer doesn't break because they don't want a new one.
The only saving grace that M$ has is that the general population (in America) have absolutely no idea they have a choice. Even now, if you mention the word Linux to someone they have no idea what you are talking about. No doubt about it, non gamers would be so much happier with a good distro like Mint etc. than with Win10...I would bet my house on it.
