  1. If you had an upgrade key, it would work. If you have a full retail copy, then you will have to back up your data and do a clean install. There's really no way around it.
  2. Normally a Toshibia Install disk is an OEM version and probably only has the preium version on it.. A key for the professional Version will probably not work, even if you did a clean install using the Toshibia DVD.
  3. Yes you can do it. I did an in "Windows Any Time Upgrade" on my Acer laptop to Win 7 Pro. As long as the key is valid it does not matter if it is an Upgrade key or a Full version key and it is x64/x86 respectively (meaning, you can't use a 32 bit key with x64).

    To do this, just search for "Windows Any time upgrade" in the start menu.

    ^+1
    backing up and saving is always a safe way but i feel you can just upgrade and not have to full install..
  5. ^+1 on backing up anything important before doing any major OS upgrades (ie SPs, IE9,etc).
