I'm sure this has been answered before somewhere but I would like some direct answers to this particular question. I have a bunch of systems that have been shipped from manufacturer with Vista Home whatever 64bit. I assume these are OEM licenses.
I need to get these systems running Vista Business, 32-bit. Firstly, checking this page out it would appear this is a valid (licensing) upgrade path - http://windowshelp.microsoft.com/Windows/en-us/help/3af7e05f-4d2a-4af7-a168-9242f9093bb81033.mspx
. I cannot see anything saying I cannot upgrade from a 64-bit OS license to a 32-bit one, but confirmation would be nice.
Second - the last I remember using an upgrade CD, it just asked me for the previous OS's key to allow me to continue with the install. Is this still the case? Buy an upgrade CD, reformat (can't go from 64 to 32-bit now can I?), type in the previous license key, then the new one and bob's yer' uncle.
