I forgot to state I have a 2TB external HDD available
“I forgot to state I have a 2TB external HDD available”
From your WIN 7 Machines...load all your important files onto this external hard drive.
Important files are typically found in:
Downloads
Documents
Desktop
Photos
Videos
Music
Also save yr favorites from internet explorer
CHROME — Find how to export and save your bookmarks
FIREFOX — Same as Chrome...export/save yr bookmarks
Save the above onto external hard drive.
On yr new Windows 10 machine you install all or part of what you saved on your external hard drive. Me -— I would only install the really important files onto the new Windows 10 machine. You can always plug in yr external hard drive to access yr ol Windows 7 machine’s files.
