So the new Windows 10 updates are causing nightmares for my clients, one thing that the other poster mentioned is to turn off your pc each night. However also make sure you have auto update off! Microsoft updates are normally ok but some of them you just do not need. I would advise that before you install a new update simply type it into Google first as there will be threads on it, then if you happy install it.
Another issue with the new Windows 10 update is that it takes off your sound drivers and changes your keyboard to USA Default. Both of these can easily be fixed, just go into your start bar and type "preferences" then either roll back the sound driver to a time where you new it worked, or download new software. The keyboard issue can be fixed very easy by just installing the UK pack.
Hope that helped a little!
