I'll be honest...
I've gone from Win98SE to XP to Win7. I won't use ME, Vista, or 8.0. ME and Vista are horrible in their own right and I quickly grew tired of the issues. Windows8.X flavours don't suit me very well... I consider myself a bit of an industrial computer user who tries to focus on the utility and use more than cosmetics and 'ease of use' ... because unfortunately making something easy and foolproof for my grandparent's complicates the crap out of trying to do anything out of the ordinary with the machine.
I don't need to go into more detail about that one... as you had to go digging for an MSI file to install your 'trusted' software.
I've been called paranoid for a long while now when it comes to Windows, iOS, and Android, but at this point in time it's too late to do anything about it. Everything is cloud based, or provided in a form of subscription. Hence the abbreviations in the IT world such as SaaS. Software as a Service. Things are no longer being installed locally, but served online with evolving Terms of Use and Servive. Anyway... enough of that rant, and back to Win10 . I've recommended against using it for a number of security concerns. I realize it's still a work in progress, but the access that MS retains over user data is scary. Do a quick search for privacy concerns and you will find a number of articles outlining ways to try to stop many of these built in spyware like services.
Lucky for us, programs are moving away from windows and into online services and subscriptions... It's a double-edged sword, but will soon make it much easier to remove the requirement to have windows based machines in the home or work environment. Any machine with a supported browser will work, and this includes *Nix variations, windows and Mac. Freedom is coming for those who want it, but for those of us who think that 'free' truly is free, and are never bothered to read terms of use... well, I won't ruin the surprise.
This is a facebook demotivational poster... but it applies everywhere.
