My example why I can't upgrade and regularly have to fight the updates that try to force me again and again: two notebooks, one older, one relatively recent. Windows 10 breaks things on both. On the older, even if the "Update to 10" says "everything's OK," after the update the machine is so unstable that it gets often stuck and crashes regularly. It has enough RAM, the cause is "officially unsupported" Intel WiFi card that I can't replace with the newer. On the newer notebook, the touchpad remains effectively broken: its sensitivity is different, the scroll areas can't be activated. The screen is somehow also more prone to temporary "burn-in" effects. The notebook is specifically not listed by the manufacturer as "upgradable to Windows 10." Microsoft however forces upgrade again and again. From my point of view, Windows 10 upgrade definitely has problems with notebooks.
