I'm trying to help a client with a Sony Vaio laptop model VPCEB47GM. Windows 7. I believe it was purchased within the last year but I don't know the date. The user was DEFINITELY using MS Office - Word and Excel up until we removed his username and cleared out his profile and created a brand new user. (New user was created first, then we deleted the old username). I do NOT know if Office came with the laptop preinstalled or he purchased and installed separately but knowing his low tech capability I think it's almost certain Office was preinstalled by Sony.
Now, logged in as the new user, when word or excel files are opened, the Office "Activate, Try or Buy" window comes up. What happened? Of course the owner doesn't have any documentation including COA that came with it. Is this really possible that creating a new user would force activation again?
