Windows 10 and Dell laptop issues

Bit the bullet and upgraded my Dell Vostro 3550 to Windows 10 (even though it shows as not compatible on the Dell website)..
All seemed to be going fine - Windows 10 logo on bootup, but then the screen went black - the backlight was on, so it seemed like Windows was running but no displaying on the laptop screen.

A quick search showed it was a common problem, and that the basically the graphics card is treating the laptop screen as another monitor, and displaying the main display on the external display (that isn't plugged in!)

Connected up a monitor via a VGA cable, and the Windows 10 logon screen was displayed. Logged in and uninstalled the Intel HD 3000 Graphics card, and then let Windows download the latest driver from Windows Update.

Have also fixed a Dell Inspiron which had the same problem, but upgrading the graphics drivers didn't resolve the issue. Upgraded the BIOS as well as it was on a old version, and laptop screen worked as it should after a reboot.

Easy Transfer Wizard not working

Trying to swap out a PC today, so was using the Easy Transfer Wizard built into Windows 7.
Both old and new PC's were on the network, and could talk to each other, but working through the screens, and entering the code it looked like it was starting to work, then both PC's would display the following:

Windows Easy Transfer is unable to continue. Please reboot computer and try again.

Really helpful!

There was an unknown account showing in the user profiles, so deleted it (i'm assuming it was the $client_setup$ account that the Connector software creates to join to the domain), so deleted, rebooted and successfully managed to copy the user's profile across to the new PC.
