I had 2 hard drives one running win 7 home and the other running the win 10 preview the lates both crashed
the lates build ran ok and I was happy so I disconnected that hard drive and upgrade my windows 7 it worked ok for a bit but next day the task bar quit working. This happened a few times before in some of the older builds. I tried all the fixes but
as before none worked for me. so I had to reload my windows 7 from my recovery disks. Meanwhile I needed access to my email so I disconnected the windows 7 hard drive and reconnected my up to date windows 10 preview. It would not load I would sign in
and get a black page with mouse. I tried to run repairs etc but could not. So I reloaded the last windows 10 preview I had It worked ok but of course it is old and I cannot get any updates for it.
I had a few problems similar with different updates on older previews that always led me to reinstall.
I have quite a few windows 10 upgrades to do and not sure I should. I have seen others are having issues also especiaLLY WITH WINDOWS 7 upgrades.
I will try again once I get all my updates.
Just a note when windows 7 upgrade to 10 home it worked ok one thing I did do was change the log in to log in with my microsoft account. that is when things messed up. I seem to lose admin rights and my one drive was not working right
Feed back would be nice. thanks
