I have a Dell xps 8700..says it is fully compatible for win10.  However, I upgraded and could not connect to the internet.  Both ethernet and wireless adapters said limited connectivity.   When i ran diagnostics in win10 said, drivers where outdated   When I tried to update, said they were fine.   Went back to win 7 and everything works.  Checked Dell site for upgraded driver and found none.  Any suggestions>
