OK, I have a never used Win 7 Professional upgrade. I'd like to sell it
on a local radio swap shop. Looking at NewEgg, they have an OEM price
of about $140. What is the downside of an OEM package. I suspect you
get no support from MS. With MS, maybe it's 30 days?
OEM - no support from MS, and it is tied to the first computer it is
installed on (which for practical purposes usually means the
motherboard).
Also if yours is an _upgrade_, it is only valid to be installed on a PC
that already had a qualifying Windows on it (for 7 I think that means XP
or Vista, with XP qualifying but still resulting in a clean install of
7, and Vista giving the _option_ of an upgrade-in-place). The OEM may -
with the above reservation about it not being transferable - be an
install-from-cold rather than an upgrade-only; since OEMs are mainly for
"system builders" (small computer shops or home constructors), it
probably is.
I don't know if you get any support from MS for an OEM edition: you
might be right about the 30 days, though I suspect that's the limit for
full retail. There's another thing that's about 30 days (IIRR), and
that's the time before activation is required to retain full
functionality.
