Answer = No.
If you're upgrading from an older operating system (XP, Vista etc.) then you will be given the option in the Windows 7 installation to transfer your files.
If you are upgrading from an older version of Windows as in 7 or 8 you should lose nothing. If you are clearing off your current OS and installing Windows 10 by yourself then you will lose everything as your files are saved in the Windows "Files Explore". It is recommended to make a backup before doing a clear wipe.
Simple. You install 7-Zip.
This is possible. You could backup all your important files, install windows 7 then restore all your files. You won't be able to migrate applications when you are downgrading

You can't really, if you're desperate you will have to re-install windows
Sorry about this but, you cannot =(
If you have access to a XP computer, you can copy C:\ESRI and paste it in a folder on Windows 7 with the same name. Copy the files in C:\Program Files\Common Files\ESRI from you XP computer to the folder C:Program Files (x64)\Common Files\ESRI on your Windows 7 machine. After you have to copy the ESRI font and install it on Windows 7. If this doesn't work, there is a second option which can be read at gislounge.

If you are upgrading to Windows 8 from an older Windows version like Vista or 7 you should not lose any files as Windows has developed the transition to be nice and smooth. If you are clearing off the OS completely and manually installing Windows 8 then it is recommended to have a backup of your files.
I do not think so. When you start the program it will ask for location with Windows 7 distrubutive.
If you have the install disc, yes. However it will delete all of your files and settings. It would be like turning on your computer for the first time.
There are no special files you need to install with Windows 7. Use a browser, like Internet Explorer, to display HTML formatted documents and web pages.
