Windows 7 volume license alongside OEM stickers?
Posted on 2014-03-05
An office I'm doing work for has a bunch of computers - about 40 of them, and MOST of them are licensed with a Windows 7 Professional OEM sticker affixed to the side of the computer by the manufacturer.
But, they also have a couple of old computers that originally came with Vista, and a few custom build PCs which have Windows 7 on them, but have no sticker (I'm assuming that during installation the licenses were poached from the other computers and activated over the telephone).
In total, there are about 6-8 computers that I would say are improperly licensed.
They're upgrading some systems now and they're trying to license everything properly so this is a good time for me to get them a handful of Volume Licenses for Windows 7 Professional under the Microsoft Open Volume License Program.
1. Do they have to buy 40 volume licenses, one for EVERY computer at the office, or do they just need enough to cover the computers that are not otherwise licensed via an OEM license sticker?
2. When they buy new computers, if it has a Windows 7 Professional OEM sticker and they then wipe the hard drive and install Windows 7 from their deployment image which uses the volume license key, is this installation still licensed via the oem sticker, or is it now a volume license computer and consumes one of their volume license seats?
3. If the answer to #1 is "you need 40 licenses", then is there any major benefit with regards to system administration for them to have volume license keys as opposed to just buying a few retail copies of Windows 7 on an as needed basis to fill in the cracks?
4. Can you buy an OEM license sticker, and affix it to an existing computer that originally shipped with Windows Vista, install Windows 7 Professional on it, and consider the computer to now be properly licensed? Or is it a problem that the OEM license wasn't originally shipped with the system when it was first built?
