Just for the record, it's not so much that Win 10 in itself is a bad OS, but rather that MS is forcing on users and not giving them a choice to 'upgrade' or not. There are also components of Win 10 that just should not be there: telemetry; tracking; phone home apps under the guise of providing better services. Okay, so Siri can let you know of the closest restaurants and when the next bus is, but at what cost to privacy. Then there's the enforced updates that can fech up your PC and take hours to fix...
If MS were to fix these things and hand 'past controls back to users, then perhaps Win 10 could be the best OS they've produced. Until then, it is by far the worst, and given that plans are underway to introduce the same abhorrent things to Win 7 and Win 8/8.1, something really needs to be done to curb the patently wrong methods and ideas MS has adopted since Satya Nadella took over. Frankly, Windows is not the most attractive OS anymore, with long-term Windows users switching to Linux or Apple's OS-X to avoid to bully-boy tactics of Microsoft.
In a nutshell, Microsoft has fucked up severely under the 'leadership' of Nadella, and Bill Gates needs to retake the head position as CEO if Microsoft is to survive this discontent from users worldwide.
