Both I and the administrator of my building use win 7. Recently both of us have seen an "INVITE" dialog in the tray to upgrade to win 10 by setting a date in the future for the change. In my case I ignored it and it went away. In my admins case the change from 7 to 10 was done WITHOUT her permission. She has the CDs for win 7. She was told that if the change is less than 30 days old she can go back to 7 retaining programs, files, docs ect. Is this true? If yes how does she do it? If not will she need to do a fresh install of 7? How to retrieve docs, files, programs before the install? external hdd? Flash drive? Then install and copying flash to hdd? Any help for her welcome.
