It seems that every Win 10 drama has variations on a similar deal. Like cancer, no two Win 10 illnesses have identical genetics. Home based business. Five Win 10 desktops, two laptops. Some 64 bit, some 32 bit. Only the laptops upgraded from Win 7 pro to Win 10 with minimum fuss and have run almost flawlessly as every customer of MS has a right to expect. The desktop Win 10 machines crash repeatedly, every few days. Once repaired and running again, often for no rational reason other than a MS update or some other secret background intervention, they will crash again within a few days and be out of action for a few days and sometimes for weeks. Invariably (in the least worst case scenario), it takes days to get them going again. The initial roll out of Win 10, resulted in multiple failures. Subsequent roll-backs failed and corrupted the OS to be unusable. Reinstalls followed. Toward the end of the free install period, we decided to upgrade again, thinking that the early problems would have been sorted by MS. BIG MISTAKE. The Win 10 installs generally succeeded, but ever since, Win 10 crashes beyond repair have occurred weekly. If one of the desktops is working on any given day, then that would be a good day for my business. Usually the computer crashes to death. Most crashes over the past few months result in a subsequent failure to post. Sometimes the system SSD will become "locked" for some inexplicably idiotic non-reason. If post-crash, a posting occurs miraculously, then the BIOS can be accessed at least to try to restart use USB repair which fails for a variety of reasons, none rational. Despite following all of the supposed "expert" advice online, nothing works. Accessing SAFE MODE is a pain in the butt difficult if not impossible. Why does MS make everything as difficult as possible? That's like asking the Man in the Moon why he doesn't frown. Surely there must be enough severely disgruntled Win Tenners to start a class action against MS to recover the costs of business down-time directly attributable to Win 10 disasters? Win 10 in most cases is extraordinarily unreliable and dismally crash prone. Win 10 is a global business disaster. It could hardly be worse if it had been devised by ISIS. If Win 10 were an automobile, it would have been declared publicly to be a rotten lemon. The solution is to give Ten the flick. MS is an acronym for Multiple Sclerosis, for which there is no cure.
