How To: Use Your Windows 7 Upgrade Disk On a Fresh PC
Posted 10/27/09 at 10:30:00 AM by Justin Kerr
Anyone who tried to install their upgrade version of Windows 7 to a fresh drive was treated to a cruel wake up call. Not when they installed the OS, not even after they installed all their applications, but when the time came to activate. The deal with upgrade media is simple, an existing, and activated copy of Windows must exist on the hard drive prior to installation, or be prepared to start over. To make matters worse, the activation warning doesn't even give you a phone number to call and appeal you're case. The good news is you’re not dead in the water, that is, as long as you're comfortable making a few simple registry edits.
This guide will give you tips on all the upgrading scenarios, and even teach you how to use your upgrade DVD to perform a clean install on a fresh system with no prior OS. We show you how to turn the tables on the dreaded activation error code 0xC004F061: "The Software Licensing Service determined that this specified product key can only be used for upgrade, not for clean installations."
First, lets quickly review what you can do with the upgrade disk, and how you should approach each upgrade scenario.
Vista Specific Upgrades

Scenario 1
You’re doing an in-place upgrade from the same edition of Vista to the same edition of Windows 7. For example, Windows Vista Home Premium to Windows 7 Home Premium, Windows Vista Ultimate to Windows 7 Ultimate, etc.
Next Steps
Just pop in your upgrade DVD while in Vista and follow the prompts, this one is drop dead simple! Activation should go off without a hitch.
Scenario 2
You're upgrading your copy of Windows Vista to a different edition of Windows 7. For example, Vista Ultimate to Windows 7 Home Premium, or Vista Business to Windows 7 Ultimate.
Next Steps
You will need to boot from the CD and perform a clean install. Do not format your drive using any program other than the Windows installer, or you will be forced to perform the registry hack listed below in order to activate.
If you install Windows 7 to the same drive that Vista is currently located on without formatting, the contents will be moved to Windows.old that you can sift through or delete later.
Clean Install / Fresh Install
Scenario 3
You’re doing a clean install of Windows 7, and Windows Vista, Windows XP, or Windows 2000 is currently installed.
Next Steps
Do not format your drive using anything other than the Windows installer. Simply boot from the CD and either format the drive when given the option, or install to the same drive which will create a Windows.old folder with your previous data.
Scenario 4
You have a freshly built system with a totally blank or formatted hard drive.
Next Steps
You could install a previous version of Windows, activate it, then go ahead and install Windows 7 using one of the scenarios listed above which some call “The Double Install Method”, or you could follow the steps on the next page to trick the activation service into thinking it found a previous version.

THANK YOU! This was greatly apprceciated. You lowered my blood pressure 10s (if not 100s) of points. Microsoft deserves their money and protection but I deserve the time back I spent on this issue...unnecessarily.
I FULLY agree that its rather underhanded to allow users to install without a product key, fine tune their systems, then not allow them to activate, with no phone number to call. This also happened to me and I spent my valuable time doing what Microsoft said was a simple short excercise.WHY CAN'T THEY PUT THIS FACT IN BIG BIG LETTERS so you see it before spending 3-4 hours upgrading only to find you "need" to start again.
I will seriously consider Macintosh the next time. I spend far far far far few hours "maintaining" my Mac than I do my PC. I was hoping for better in Windows 7 but it looks like the same old story.
Thanks again.

Doesn't if figure that MS would take something as good as Win7 and FRACK IT UP with stupidity like this. I swear they GOAD people into pirating their stuff with this kind of crap.
Oh, and CrashTECH - Get off your high horse and realize that the people who want to pirate Win7 wouldn't be complaining in this board about ACTIVATING it. DUH. No - people are pissed that MS penalizes the PAYING customer by adding in this bass-ackwards install step making things take twice as long.
I buy my software - I have more licensed copies of several versions of Windows laying around than I know what to do with. I was hoping to use Win7 for many years to come, but I don't want to sign up for double installing OS's simply because MS puts a lame ass attempt at stemming piracy. Yeah, like this will help deter the pirates. PLEASE. The only thing it does is piss off the honest people and make them want to BE pirates. I'd imagine several people will end up buying a legal copy and then using a pirated installer simply because its easier. They might as well name this Windows 7 CS by Adobe..
I don't know why I expect more from MS, I really should know better by now.

Windows 7 Upgrade
Submitted by Riskjudge911 on Thu, 11/05/2009 - 11:13am
I have the retail version but my friend got the Upgrade Home Premium. He wiped his hard drive, then installed Windows 7 Upgrade Home Premium..then after installation was done he rebooted and re-installed Windows 7 over the previous installation that he just installed. This fooled the system into thinking it had a previous OS. Then he activated it and boom no problems at all. So if you don't want to rename anything or mess with the registry this method works too. (Although takes a bit more time).
Windows.old

Totally works
Formated my raptor drive then dropped in the Upgrade CD i recieved today and done the install procedure. Got into windows first thing i did was make a windows.old folder and then went onto activation and it worked.
Ive got legit keys for XP anywhos so doesnt really matter to me but one less step is nice.

Submitted by arkweld on Tue, 10/27/2009 - 2:54pm
there's a pretty simple way to upgrade software that many other software retailers use but MS didn't. Just don't supply new registration numbers with upgrade packs and get the user to enter the existing serial number for their previous OS.
MS could even have used the disk check method during install and that would have saved time.
Clean Install Using Upgrade
Submitted by sammyd253 on Tue, 10/27/2009 - 2:25pm
Someone probably already posted this, but...
I purchased a retail copy of Windows 7 Home Premium Upgrade from Best Buy. I threw the 64-bit copy in my dvd-rom, booted my PC from that drive, formatted my drive and chose to install there. Once setup prompted me for my product key, I didn't enter it. Setup finishes and you'll eventually boot into your freshly installed OS. Install your drivers, and install ALL Windows Updates. Run Windows Updates and reboot until you can't get new updates. Then activate your copy of Windows using your product key. It should go through no problem. If it doesn't, then you have to move onto the registry hack method.
Either way, you can avoid having to install a previous version of the OS first.
Hope this helps! And if someone already posted this, my bad.
Fresh Install with Legit Upgrade
Submitted by HokieTechie on Tue, 10/27/2009 - 1:20pm
This "you have a copy of XP, so you are fine" argument only works for your first Windows 7 install.
In the course of my legitimate ownership of a Windows XP Upgrade (from a legal copy of Windows 98), I have done a fresh reinstall because of a hard drive failure, a fresh reinstall because of a motherboard upgrade, and a fresh reinstall just because I built up to much runtime crap over the course of several years of normal use. Each of these actions is perfectly legit under the non-OEM license.
Microsoft's new "you must install and activate and install XP first" would have added a large amount of pointless effort to each of these steps. And, one day, if I upgrade from Windows 7 to Windows whatever, does Microsoft expect me to install 3 operating systems?
Someone in Redmond just isn't thinking ahead about all the ways that their product is (legally) used.

Submitted by DoctorX on Tue, 10/27/2009 - 1:14pm
Why are you harping on the upgrade having to have a valid OS? Almost everyone here does. But most like me do not want any garbage from the old install on the new install. Clean install is still the best way.
Have a little consideration dude!

on my main machine I had the RTM build installed, and was able to use the upgrade version to install without issue. and that wasn't not a validated/activated prior install.
if needed, I could have reinstalled XP and activated it, but I am glad I didn't have to sit through two OS installs.
New SSD & Win7 fresh install
Submitted by sotoa on Tue, 10/27/2009 - 10:40am
Win7 Pro is sitting in the unopened box until my SSD 160GB Intel arrives. This baby is getting a FRESH install. Was waiting for prices to drop, TRIM to be available and Intel to add the TRIM firmware.
So why should I install Vista, activate, then install Win7? I want as little garbage on my SSD as possible. The MOST hoops they should do is ask for the old DVD as verification or something. Why be treated like a criminal?
I'm going to try these tricks first.

Submitted by CrashTECH on Tue, 10/27/2009 - 8:56am
If you don't have a valid license for a prior OS, it serves you right for trying to get it cheap by cheating and getting an upgrade license. It is called an upgrade because you are UPGRADING from prior version. You don't have a prior version you say? Oh, tough luck, go buy the retail version and stop whining because MS punished you for not abiding by the terms of the EULA.

Personally, I canceled my pre-order of Office 7 Progessional Upgrade
when I read about this "cannot do a clean install" nonsense, and I will
continue to run XP into the indefinite future. Microsoft really screwed
the paying customer on this one.I am glad to see that the hack
is easy to explain and to execute. I hope Microsoft has the good sense
to see their mistake and not to try to nerf this in a WGA update or in
Windows 7 SP 1.

You have a prior version, you are fine. MS didn't screw anybody. You have a prior version installed you XP would have become Windows.Old and you would have been just fine.
I don't think they are retarded
Submitted by Wonko33 on Tue, 10/27/2009 - 6:43am
I think they just don't mind that people do it. I mean you paid for the product, and really who doesn't have win vista or XP right now? (You could say Mac people but I am talking about people with computers).
And even if someone doesn't have a previous version of windows, well that's a new "convert" so who cares. It's not like we didn't pay for Win 7 when we do this.
It really is win-win to let us do that, they just have a different official policy.
I would've posted that myself....
Submitted by keithfreitag on Tue, 10/27/2009 - 5:36am
I would've posted that myself but I figured I might get in trouble from Microsoft. Those are the steps they walked me through when I custom upgraded (clean install) over XP to 7 Home Prem Family Pack. I just explained that MS says for XP users to do a custom install to a clean drive and then restore all programs and files. So when it didn't work, MS is responsible for the fix. Had I know it was OK to post those steps, I would've done it last week and saved some headaches.

Submitted by allantang on Tue, 10/27/2009 - 2:14am
I was running Win7 RC1 and did a full clean install with the upgrade dvd, doing the double install.
I first booted from the dvd and formated the drive through the installer, then installed, all using the custom installer. I did not enter they key during the install, it will of course say that it is an upgrade key...
Once the install was finished and windows is loaded, I opened the dvd from windows, ran the installer again, and did the upgrade install option.
Once everything was finished I entered my key and windows was activated, no problem. I have done this with pro and home premium.
Now that I think of it though I did not use the actual upgrade dvd. I used the technet dvds downloaded from microsoft... but still worked with my upgrade key doing this process.
Not me...

Submitted by jimmynemo2 on Mon, 10/26/2009 - 8:24pm
so I'd read these same tips on other sites, but when i tried them on a particular PC, they didnt work. So on a long shot I tried something that I've now repeated and verified on 4 PC's since:
Just install a clean install, Dont enter any Key when asked. Then, once you are read y to activate, create a folder called Windows.old on the root of your C: drive, then activate with your key just like normal. I know, it sounds too simple, and that it's too big a loophole for them to have missed, but it's worked for me 4 times now and my machines are on a retail upgrade disc and key.
Hope this helps someone.
I like simplicity...
Submitted by Larry Lee on Sat, 10/31/2009 - 8:26am
So, the way I see it, you simply format your hard drive for a clean install, (after backing up your important data, of course) then you skip the initial registration during the install and create an empty folder in the root of the C: drive named windows.old and THEN you register Windows 7 and apply the updates.
That's simple enough!
Wow. I bet Micro$oft will fix that workaround with SP1 and your fresh install will deactivate when the windows.old folder is found to be empty.
Can they get away with that?
I bet they can.

Very interesting. Sounds like what they used to do to validate you had a previous version. So they didn't change that like they thought they did? Very useful to know Jimmy.
nope
Submitted by jimmynemo2 on Tue, 10/27/2009 - 8:30am
No I guess they didnt, becuase the folder was completely empty, so there was no previous key to be verified. I dont think Im just missing anything becuase the first machine I did this on didnt have any windows OS on it at all, it went from ubuntu to ubuntu / win7, so yeah, absolutely no verification of keys, just verification of the windows.old folder.

I thought it actually made note of the old product key and verified it.
But your method seems to exploit a similar vunerability by making it look like there was a previous windows. But it looks like it doesn't check to see if the old version was activated, though.
