Re: New Computer Help
The issue you might encounter if you try to install Win 7 on that machine is finding Win 7 drivers for a laptop that was designed for Win 10. Go to the laptop mfrs website and check to see if they provide Win 7 drivers. If they do, download them to a USB thumbdrive so you'll have them for when you install Win 7. Of course you'll also need a Win 7 install disk and valid product key.
I personally have never used Windows Easy Transfer since I feel it's simpler to just copy the files I want from the old to the new over the network or using an external dock like crazyman143 suggested. I think Easy Transfer also copies settings and such which I don't care about. However, lots of people use and like it.
Another reason why I don't use Easy Transfer is because I keep very little data on the local machine. I have a server where I keep all my pictures, music, videos, documents, etc... so any machine I connect to my network has access to them. Additionally, any files I wish to have available on all machines are saved in DropBox which automatically syncs them to all my computers.
