I really wonder if it is worth it getting the upgrade until 29th july. Some people said that the upgrade process messed up their whole system (some kind of disk bug that it was busy 100% all the time or no programm working anymore) but some say that it worked well and Windows 10 is running alot better than Windows 7.
What do you guys think? Should I upgrade? And if so, is there a safe way to "revert" the upgrade to Windows 10 to make my system running again?
