my boyfriends home built computer he put the free upgrade for windows 10 on it and after he did that it fryed his prosscer n and other things on his computer he had to spend almost $400.00 in getting new parts for his computer . so he put windows 10 back on there and after that he ran a test to see what the temp was reading n it did a emeracy shut down and almost fryed the new parts he just put on there . then he was working on a Toshiba laptap and it read on the temp thing my laptop was almost at 200 degress cs so he had to take it all a part n fix the cpu and more so now my Toshiba has windows 8 on it and it works fine .he put 7 back on his homebuilt computer and it works fine to. but we have called u guys 2 times and told u what happened to our stuff and u guys kept hanging up on us . so we r writeing u here now .he has a lot of people coming to him to fix other computers because they don't want windows ten on there computers to . me and him do not recamend any of ur windows ten to anyone because it is nothing but crap n tries up all ur stuff to n then u have to replace everything to .so if I was u guys I would get ur shit fixed un stead of putting it out on the market like it is . thank u so much I hope that after what we have told u what happened to our stuff u will get it that people don't like it and hope that it does not sell at all and u leave windows 7&8 out because it seems like no one has issures with them .thanks.
