Is it OK to Use OEM Windows on Your Own PC? Don't Ask Microsoft

While researching my most recent article, No OEM For You: Windows 7 OEM Packaging is Not For Individuals, I ran into an issue that I should have foreseen: Microsoft's licensing reads like the Dead Sea Scrolls and you need to be an expert in Aramaic to understand it. I don't speak this EULA language, but I know someone who does, Ed Bott. And coincidentally, but not surprisingly, he was actually working on his own post about the OEM versions of Windows 7 when I pinged him. And as he promised, his own more thorough post is now available. It's a must-read.

If Microsoft expects its customers to take license agreements seriously, it has a responsibility to communicate the terms of those agreements to its customers clearly and unambiguously. As I noted earlier this month, Microsoft does a generally poor job of explaining its complicated rules for how Windows licensing works. But I deliberately left one type of Windows license off that list, because it deserves its own special place in the Corporate Communications Hall of Shame.

I’m talking about OEM System Builder licenses for Windows desktop editions. If you look at any online shopping site that caters to PC enthusiasts, you’ll find these copies displayed alongside the upgrade and full license packages that Microsoft says retail customers are supposed to buy.

According to Microsoft, [those who] bought that software and installed it on their own new (or old) PC ... are violating the terms of the OEM System Builder license agreement, which says, in convoluted language, that you must install the software using the OEM Preinstallation Kit and then resell the PC to a third party. If you install that software on your own PC, you don’t have a “genuine” copy of Windows.

Be sure to check out the full post which, thanks to Microsoft's secretive practices, reads like a Dan Brown mystery, except of course that Ed's post is well-written and has to do with EULAs, and not the Masons. You get the idea.

I really don't care what the stupid license agreement says. When I build my own computer, I will be using an OEM copy. Major props to Ed Bott for recommending that users use OEM copies.

Ha ha ha! That's good! What if you give the computer to someone? Does that count? Or you sell the computer to your roommate for a buck then buy it right back. Or say it's for your dog. No wonder Microsoft software is so danged overpriced! They've got to pay their lawyers to make up stuff like this! So sad. Funny, but sad.

This is ridiculous. It's insane how non-transparent and contradictory Microsoft has been with Windows 7 licensing. It really has cast a dark shadow over what otherwise would have been a spectacular product launch. They have got to figure it out before Windows 8 comes around.

Its the responsibility of Microsoft to clearly state what out rights are. I suspect they don't mind home builders using OEM software as long as you don't expect them to support it. The legalese is intended to lawyer their way out of normal support calls they will get. Its okay, when I install OEM software I expect to support it myself. If I pay for full retail I know I get support and the ability to move the license.

Waethorn has been posting this all along. As well as the OEM, you cannot transfer a license to another [different] motherboard if it was installed with a prior purchased retail computer. For example, your motherboard dies or you just want to upgrade. While you probably can replace the mobo with an identical one, upgrading requires a new license. But this may not apply to retail versions of Windows. However, it does apply to installations on retail computers [Dell, HOP, Sony, etc...] I doubt that MS would enforce it at all in the future.

I think they are purposely being this way. On the one hand, they don't want to encourage people in general to do this, but they aren't going to stop you if you try and know what to do. Kind of a wink and a handshake kind of thing.

Wow, when I laughed at the upgrade table so many months ago, I really had no idea how funny this would get. The Dead Sea Scrolls is an apt metaphor, because you boys sound like Talmudic scholars trying to parse increasing fine distinctions that don't even matter to anyone else. I am pleased to see Ed, Paul, et al call Microsoft out on this. The whole thing is bizarre and centers on Microsoft's obsessive control reflex....something that goes all the way back to Gates' original screed against pirates (what, a few dozen?) who stole his Basic interpreter circa 1979 (I'm sure Mike can correct me on the exact date.) So, what's the story with an OEM license on a virtual machine? I don't speak EULA either....all I know is that it works...

The same ought to apply to Virtual Machines.

You are only supposed to use the OEM version if you are actually an OEM. That's too hard to understand?

chuckb Bill Gates' "An Open Letter to Hobbyists" was dated February 3, 1976 and was published in the January 1976 issue of Homebrew Computer Club Newsletter. And, amazingly, is still relevent today. It's interesting to note that the actual OEMs here, such as Waethorn, have no trouble with understanding the rules that govern being an OEM of Microsoft. The people who DO seem to have a problem with the OEM agreement are the non-OEMs who want to find a loophole in the agreement that would allow them to not have to pay retail. Seriously, do you guys also try to set up fake car dealerships so you can buy a Chevy at wholesale and then complain that the terms of the dealer agreement aren't set up so that you only have to buy one car?

"You are only supposed to use the OEM version if you are actually an OEM. That's too hard to understand?" Its not a difficult concept, except that many vendors list that version for sale, and end users & salespeople may not know the difference. Go to Amazon and lookup Windows 7, then narrow down to software, OS, Microsoft, and you get about dozen items listed, and the OEM is not even one of them. How would an average user determine the correct one to buy?

Yoshi It sounds like you are saying that Amazon, who sells almost exclusively to retail customers, is right in not selling the OEM version and that the computer parts suppliers who DO sell to both retail and OEM customers should do a better job of explaining and enforcing the OEM wholesale rules. Does that sum it up?

Also as an FYI: In approximately two hours I will, once again, be officially consulting to Microsoft. As such, I'll be vastly cutting back my posting on all computer boards and blog comment areas such as this one. I do this whenever I have an official connection to Microsoft since some people could choose to read my postings as "official" statements and I'd rather avoid that confusion. As always, it's been fun. Mike

Mike, What I am really getting at is that all the different versions of Windows can really overwhelm most computer users. While retailers should know the difference between them all, that certainly does not happen all the time. Especially with webstores. A user looking to buy Windows 7 can easily choose the wrong version. This is one area where Apple really got it right. One version. If your hardware supports it, that's all you need. No upgrade, OEM, starter, 32 vs 64 bit, Premium, Professional, Enterprise, etc. I helped my assistant a few weeks ago order a new computer. She had no idea which version to get with her new computer and the only decision was professional vs. home and 32 vs 64 bit. She was overwhelmed with 4 choices. Think of how confusing it is when you have 12 types staring you in the face.

on Nov 16, 2009
Yoshipod Comparing Apple's OEM agreement to Microsoft's would only be relevent if Apple actually had OEMs. If I shop in a grocery store that only sells their own house brands I don't have to make many choices either but I lose out on the wealth of options I have at a full featured store. I don't go to the full featured store and tell them how awful it is that I have to choose between a dozen different spaghetti sauces.

Anyway... microsoft is not so stiff... Last years I build a PC and I try to install my OEM copy of Windows, wich came with another machine and the setup tell me to call microsoft to activate it, because he did not recognize the harware, so I call Microsoft and I talk to Microsoft staff dans told the trouth ... I want to use a copy of my OEM version on a new PC, which is suppose to be illegal, and the guy at Microsoft told me it is no problem and give me a key to active the Windows ...So... Microsoft is really dealable when we talk about OEM things...

Mike, You would have a point about the options, except that every version of Mac OS X has all the features. Good luck with your consulting. These boards won't be the same without you!
mikegalos@msn.com
on Nov 16, 2009
Yoshi The issue of how many retail versions to have is a very different one than whether to have an OEM channel. As for the "every version of Mac OS X has all the features", that isn't true. There are features on the Server version that are not on the Desktop. While Microsoft could say, "OK, no more multiple versions, everybody can only buy Ultimate", do you really think charging people more money for features they'll never use is really what they want? Personally, I think people like being able to buy a less expensive version that is tuned for home use at a significantly lower price. Of course, when this discussion comes up, it usually ends up that people want Ultimate at the price of Starter which brings us back to people trying to buy an OEM license when they're not actually OEMs.

Comparing Apple who makes 5 different models of computers with a small amount of variety in each to the PC market Microsoft partners with is absurd. There are 10s of thousands of configurations out there, they have differnt hardware and are intended for different things. Should there be fewer versions of Windows Maybe, but different people have different needs. Not everyone needs a Core i7 running a 64 bit OS that can run in XP mode. They're perfectly happy with $399 bargain laptop from Newegg that can read email and browse. Why charge them for features they'll never use?

Erico, he did not tell me how to do it, but encourage me to search the web and I would definitely find an answer. I was only replacing a motherboard on an eMachine. It was $160 cheaper to buy a better one than pay eMachine for an identical replacement.

"As for the "every version of Mac OS X has all the features", that isn't true. There are features on the Server version that are not on the Desktop." That's really stretching it. Of course the server version is different. I did not think I needed to be so specific as we are talking about the client version. "They're perfectly happy with $399 bargain laptop from Newegg that can read email and browse. Why charge them for features they'll never use?" Apple makes it simple for their users. No need to decide now if you need that feature or not. You just get it. All for one low price. No need to spend more money later to upgrade when you realize a feature is missing from the version you bought. Just because you don't need that feature today, does not mean you won't in a few months. Microsoft could certainly sell one version of Windows, but they choose not to, in order to charge people more money. Even Paul had to spend another $80 to upgrade his new netbook to a better version of Windows 7.
Waethorn
on Nov 16, 2009
Paul, this is NOT the "End User License Agreement", as you incorrectly state (as does Ed). This is called the "System Builder License Agreement", which is not the same. The System Builder License Agreement was changed PRIOR to Windows Vista's launch in January of 2007 BTW (ie. 3 years ago), and was even included in Windows XP System Builder packages from prior to that. You think this is new with Windows 7? It's not. It wasn't even new with Windows Vista. Seems Ed just didn't even think to read the license updates that were posted to the front page of the OEM System Builder wesbite OVER 3 YEARS AGO! Sorry, but this is just EPIC FAIL!
whiplash55

The reality for most people is that Windows has 2 versions Pro and Home Premium. Apple sells one version for cheap because they make up for it on hardware, which is pretty expensive for what you get. They could sell one version Ultimate but ou don't need Ultimate for most users, so when you make your money on software you charge more for the software with more features. Apple charges $999 for a laptop with components you can match for 699 or less, they can afford to charge less for software upgrades, they already got you on the hardware, which they tend to stop supporting 2-3 years after they sold it. Just ask anyone who bought the last G5/G4 machines before they went Intel.

"So, if I build a computer for a buddy, can I use the OEM software with kit, or is this a violation? I guess my question is: what qualifies as an OEM?" You probably mean "system builder". An "OEM" is a major manufacturer that buys components directly from the vendors, often custom-built, and has a direct contract to obtain preinstallation licensing from Microsoft. A "system builder" is a smaller organization that builds computers using off-the-shelf parts purchased mainly through the distribution channel (that's what they refer to as just "the channel") and obtain Microsoft System Builder software and preinstallation licensing packs through the channel. "Do I have to have a business set up with the government, or can I just call myself an OEM since I build people computers?" As with their marketing to system builders, Microsoft recommends that system builders by software through an "Authorized Microsoft Distributor" to ensure that it is legitimate software and that it has been obtained by the distributor under Microsoft's rightful distribution policies. Microsoft Authorized Distributors DO NOT sell to the general public. They sell to registered businesses that can provide their supporting tax exemption certificates and government-issued business registrations, as do most major distribution channels for other industries. These are the currently Authorized Distributors for Canada: Ingram Micro Synnex Tech Data Supercom and for the US: Synnex Tech Data ASI D&H Ingram Micro MA Labs SED International Online resellers that sell to the general public are not listed. Funny that.

@whiplash55 way to defend MS and there crazy number of versions. I would love to see a list of how many possible versions you could buy listed on in a number list. On that list I want to see Retail versions, both 32bit, and 64bit. OEM Versions 32bit and 64bit. Upgrade version 32, 64bit, student version 32bit 64bit.....different version for different parts of the world, 32bit/64bit and on and on and on.

"you cannot transfer a license to another [different] motherboard if it was installed with a prior purchased retail computer. For example, your motherboard dies or you just want to upgrade. While you probably can replace the mobo with an identical one, upgrading requires a new license." If it dies, and the OEM or System Builder replaces it with an identical one, no problem. The point is to keep the platform the same, otherwise the chain of support is broken. No support = not allowable, in these situations. If you upgrade your own OEM PC, the manufacturer can't support a different platform or chipset or required driver set, so that's why Microsoft doesn't allow it. " this may not apply to retail versions of Windows." You're right - it doesn't. Retail versions include transfer rights, and support directly from Microsoft. Those kind of users are installing on many different platforms too. It actually costs Microsoft a lot more to support those versions than some OEM that has locked-down configurations (think about what it would cost for Apple if they released OS X to other OEM's). You can bet that the price of OS X would climb a lot, since they wouldn't be able to subsidize it with the price of hardware. "On the one hand, they don't want to encourage people in general to do this, but they aren't going to stop you if you try and know what to do. Kind of a wink and a handshake kind of thing." That's true. It doesn't make it any less illegal, but yes that is the general consensus from Microsoft support. Microsoft support reps say that Legal doesn't want resellers knowingly selling to customers that are end-users, and their stance has always been for real system builders to buy from authorized distributors, but they currently have their hands full with piracy and counterfeiting. If everything in the piracy realm were cleaned up, license breaches would be the next sight in their crosshairs.

Well my understanding is that, Retail full and upgrade edtions contain x32 and x64 editions in the box, so it is Ultimate Full Professional Full Home Premium Full Ultimate Upgrade Professional upgrade Home Premium upgrade The full retail is for system builders, "home users who build there own computer" Upgrade is for the current systems that people don't want to replace. Then when you hit the "OEM" part with Newegg and such, there are 12 choices 6 for Full installs, because they split the bit editions, and same goes for the upgrade. The online stuff is pretty much for "advanced users" so 99% of consumers won't need to care Then not to mention well over 90% of users won't even go out to buy the retail editions, so the number of people who will have to care about the editons are extremely small, to the point it wouldn't matter. For some reason some of the Apple users like to hype up that MacOSX has one edition choice," yeah who cares" If you want to talk about confusing look at Linux, there are 3 editions for Ubuntu, one for netbooks, one for desktops, one for servers, then when you get into architecture editons don't get me started and that is one, one distro in the Linux system. This is a reacurring theme that I keep seeing between Linux, Windows, and Mac OS 10.?.? Linux most direct control, and customability, most choice for what one wants, Windows, not as much control or customability but still a lot, and a smaller limted amount of choice for what one wants. Mac OSX very litte to no control over the system, little to no customability, one or two choices if you include server edition. So as we see Linux for the highly-advanced users Windows for the advanced-proficient users Mac OSX for the basic-lacking users.

so what you are saying Waethorn is that people who do breach the license by buying the newegg stuff, will never have to worry, because I have yet to see a system that PIraters and leechers can't beat. Piraters being the ones to crack the software then share/sale it to others Leechers being the ones who obtain the software from the Pirate.
DRWAM
on Nov 16, 2009
Most retailers have staff to help choose a version of Windows, so those that are confused get a 'genius' to help. That sorta makes the number of versions irrelevant. Microsoft has a support area to help too. If they are confused, they ask somebody. Besides, most look at a price range for hardware and pay no attention to the OS version. Therefore, upgraders or home builders are those to which the number of choices really make a difference, and the minority are probably not very tech savvy.

@rr0de74 Most people who would be confused by the different versions of Windows just buy new PCs. They get what it comes with and they're happy with it. I was at Best Buy over the weekend all I saw were Netbooks with Starter and everything else with Home Premium, all the full sized notebooks or desktops were running 64 bit. The people who would tend to go to newegg or Amazon to buy it themselves are plenty savvy enough to know what to buy (Home Premium or Pro) and it's not an issue for them either. So its really just an issue for people to talk about on blogs like this who don't have anything else to criticize Microsoft about, at the moment.
