Re: "Naturally, all user data is wiped with this option"
"Why can Microsoft not understand that user data needs to be on its own partition ?"
(I put my user data on /home and depending on the system, it very well COULD be on a different partition)
For Micro-shat, you have to remember, it's not YOUR computer, it's THEIR computer, for which they now have complete control over updating and installing things.[even if you do not want it].
So by THEIR standards, you use that computer by THEIR grace, at THEIR whim, and from THEIR blessings upon you. You should bow down and worship, sing praises to their names, grovel at their feet, accept their ads without question, and buy their advertised merchandise. Or at least, that's how it appears (to me) for what they want and expect...
