Win 8 Upgrade. What files doesn't it keep?

[hugobosslives]

From win 7 home premium to 8 pro. It says it keeps programs, files, and settings.

Is there anything it doesn't keep?


Also another question. If i got the disk image file from dreamspark. Is there a way of using the upgrade assistant instead of doing the clean iso install like it's wanting?

Thanks for any replies .

okay. cheers for the info.

whats the chance that i might lose stuff?

see the problem is I don't currently have an external hard drive to back stuff up.

and i'm worried i might lose my documents folder and my downloads folder if something goes wrong.

does it matter if these folders are huge? (couple of hundred gigabytes)
