Too many problems with windows 10(64 bits)

[nilamo]

It takes 15 minutes to become responsive after logging in?  Is this a new computer, or one from 1998?
It shouldn't take that long, for any reason, for a brand new, barely used, computer.  I'd suggest returning it for a replacement, as your hard drive might be faulty.

There simply is zero reason for any new computer to be that slow.  None.
