Recently I suffered a complete failure of my PC and have had to use my old vista 32-bit without a product key. I am looking to install windows 7 64-bit and I know this requires a clean install. However, would me not having a full license mean I have to buy the full version, or will it allow me to use the upgrade edition since I do have a working version of vista. Also, I have 2 Internal hard drives with a partition on my system (C: ) drive. Will a clean install wipe both hard drives and the partition, or just the C: drive? Thanks.
Thanks for the advice, also I have a few games that took ages to download. Could I just back them up and then move their files back when the new 64-bit is installed? Or does that create conflict due to them being installed on a 32-bit previously?
If game relies on registry entry then you must re-install game.
If you OWN the currently running OS, then you can use the upgrade version. However Upgrade and OEM arte about the same price so I'd go with christop and get the OEM.
