In reply to Sharp:
Windows was never "locked down" - not until Windows 8 and the Windows Store which was a reactionary move against Apple's walled-garden strategy. Even today, you can still run native executables freely and even turn off Windows Defender and User Account Control on Windows 10. It's true that the experience is a little more annoying and that Microsoft try to protect people from themselves a little too much, now, but they're victims of market forces.
They aren't trying to protect you or me or the original poster - they're trying to protect the muppets who make up the majority. If they did offer an "OWNER" mode or even an "I know what I'm doing, you don't have to hold my hand" mode, those same muppets would opt for it out of arrogance or pride or misplaced confidence and they'd still whine to Microsoft when things went wrong.
Microsoft aren't alone in this plight. I recently read a discussion in the Mozilla forums about the browser developer tools and its JavaScript console. Do you realise that people get conned into pasting and executing malicious script into that thing and "self-CSS"'ing themselves? I know, it sounds like idiocy but it still happens. As a result, many proponents want Mozilla to remove developer tools entirely.
Linux isn't an option for a large number of people for two reasons: the hardware support lottery and the "chance of a bad day."
I have spent several years as a Linux professional and even I can't run Linux on the laptop on which I type this post. Something about the hardware just doesn't work out with Linux - not Ubuntu, Debian, Slackware, Mint or Arch. I've tried, and, after about three days of fiddling, I had it working but still couldn't access my CUDA hardware (I was working on a CUDA project at the time so that was rather important) and ended up back in Windows despite my personal wishes.
There's also always the chance that you'll hit the power button one morning and, instead of getting your work done, you'll find yourself trying to resurrect a corrupt GrUB or X.org installation, scratching your head and wondering what on earth could have changed since yesterday. These are "bad days" and, when you use Linux, you have to be prepared to take them in your stride - they happen! (They happen with Windows, too, but less frequently.)
