I've seen Windows 10 updates make a computer unusable for hours, particularly for any application where a bit of processing power it needed. Forcing actions that interfere with the owner's use of a computer is another malware trait to add to the adware and spyware that MS bundled with Win 10. It is hard to believe that MS is actually getting away with this sort of behaviour. There are real consequences for Windows users, particularly those in small business that rely on MS products to operate their business but are too small to have the extra control that MS might allow large companies.
Problems with Windows are only going to get worse. Many businesses are unwilling to give up Win 7 and put up with the shit that MS is trying to force on them with Win 10. The same customers mostly avoided Win 8 so are using a OS that MS will abandon, without supplying a functional replacement. MS seems to be completely lost and confused, with an attitude of refusing to give customers what they want but still expecting them to buy their crap.
If Linux companies are smart about this, there could be a huge jump in Linux adoption that convinces more software companies to port their products to Linux. Time will tell. I know from personal experience that it has been very easy to get Win 10 users ready to try Linux.
Windows is losing relevancy as the shift to mobile devices continues and many people no longer need a desktop OS. A sign of just how significant this has become is MS releasing several products onto Android. There are an increasing number of large developers that have little interest in Windows, preferring to focus on other platforms. If MS loses their near monopoly of the desktop OS market, their whole world could come crashing down very quickly.
