Can you install Windows 8 upgrade on a totally empty (ie new) drive?


Recommended Posts

Seems reasonable, a person paying something... anything for your software still beats them just pirating it even if they are technically violating the EULA. I'm sure there will still be people that will refuse to pay regardless of how cheap it is, but in my opinion Microsoft have done a lot towards encouraging people not to pirate Windows with their low pricing.

They're probably banking on their new AppStore for the revenue stream these days - on the general consumer side at least!

This. They're selling Windows 8 for a very low price and banking on users purchasing apps or using apps with advertising from the Windows Store, knowing that once users have invested in a platform they're less likely to leave for another. The problem comes when Microsoft makes so much money through the Windows Store that they decide to add restrictions to - or eliminate altogether - x86-64 applications to a future version of Windows, as they don't make any money on those sales.

The only thing that defines what keys windows can and cannot accept is pkeyconfig.xrm-ms. So do a clean install and plop in the file that would accept the upgrade key, slmgr -ipk and boom, you're good. Might be a violation in technical terms but screw it, it gets you around the inconvenience. OR just use MSDN media, because for some weird reason that works with upgrade keys on clean installs.

Multiple people have already tried the MSDN media with the upgrade keys, and unless you do some tweaking it fails activation.

People have also already posted a way to make it work regardless. My point was that straight upgrade keys on a plain ISO without any sort of workaround will not activate without a valid prior OS install...which is the case. :p

Question: can you use the Windows 8 upgrade disc to format/reinstall a previous installation of the same upgrade disc? I like to do an annual formatting and am wondering if the upgrade disc will work.

Yeah that is usually just fine...but why do that when you can just do a refresh? It accomplishes the same thing...and why do a yearly reinstall? It's more of a placebo than anything when you do that.

Also, the License (EULA) which will be shown to you upon install also depends on the [Channel] config set in ei.cfg.

For Windows 8 and Windows 8 Pro, it is as follows:

Retail

[Channel]
_Default

[VL]
[/CODE]

OEM

[CODE][Channel]
OEM

[VL]
[/CODE]

Enterprise

[CODE][Channel]
Volume

[VL]
1[/CODE]

These EULA's are present in:

C:\Windows\System32\Licenses\neutral

[CODE]_Default = EULAID:Win_RM_2_PS_R_en-us (WINDOWS 8 PRO).

OEM = EULAID:Win_RM_3_PS_O_en-us (WINDOWS 8 PRO).

Volume = EULAID:Win_RM_1_PS_V_en-us [/CODE]

Can confirm this works with puchased retail copy (both 32/64)

-Install new drive

-Use upgrade key to install

-Can use express setting during install

-Run regedit (from desktop right click lower left of screen-Run)

-Go to: HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/

-Change MediaBootInstall from 1 to 0

-Run command prompt as administrator (from desktop right click lower left of screen-Command Prompt Admin)

-Type slmgr -rearm (wait for box to confirm rearm)

-Move mouse to lower right of screen,(opens "charm bar") pick Settings,Power,Restart

-From desktop right click lower left of screen-Run slui.exe 3

-Enter your upgrade key,activate (will take a couple seconds)

-Restart your computer (this step needed to change themes ect)

Done.

microsoft have in my view always tolerated piracy, even one of their PR people or an exec (Cant remember which) has said in public its helped them get market share.

Technet eg. was abused a lot, people paying for 1 year, grabbing keys and then using them for life, microsoft tolerated this, what they didnt like tho was people selling technet keys on ebay hence the restrictions that got added to technet. Although I think microsoft have now decided they wont tolerate people paying for just 1 year anymore as they now I believe disable keys after a subscription ends.

These upgrade keys as I understand it the same rearm trick was used in windows 7, since the trick hasnt been closed I assume microsoft are ok tolerating it because at the end of the day a upgrade sale is better than no sale. Looking at how much a OEM windows 8 pro costs, I cant see many people buying it.

Here is what worries me.

Currently I have numerous windows 7 technet keys which are 10 activations each. One is used on this PC and one on my laptop, currently I have no immediate plans to upgrade to win8 but I suspect I will do at some point, where there is apps to use win7 aero themes etc.

I have no idea when doing an upgrade which key windows 8 uses as a upgrade eligibility key, does it use the key on the pc when running the upgrade assistant? does it use the key on the windows install during the install process? because it doesnt ask for one during installation.

The keys I wanted to use is the vista oem key for my laptop and a win7 retail key for a unused boxed copy I have here in my my bedroom.

It would seem assuming the key isnt grabbed when the upgrade assistant is run that if this registry workaround is used then no eligibility is checked and as such no old keys get deactivated?

yes you can, just like vista and 7 you can do a clean install on a fresh drive, either call in the key or install windows 8, let it fail activation, rerun the setup from within the os and the upgrade will work.

Or simply do the one registry tweak after installing Win8 on a blank drive and re-arm then reboot; the method was listed earlier in this thread. Windows will then activate without a hitch. :) The way you listed works too; I've done it both ways since Win8 was released. But the registry/rearm method is a bit quicker since you won't have to install twice.

That's what I was referring to when I said that it used to be the disc that determined the install type. There used to actually be upgrade/full install discs...and as long as you knew what you were doing you could use an install key to do a full install.

This is no longer the case since the key itself determines what happens. :)

This is my last time stating this, and it is fact not supposition. So please do not keep posting your doubts over and over again.

The KEY determines the install type, not the media.

The difference is who still has a base OS install that is eligible for upgrade vs those who do not. NOTHING prevents a clean install using those keys as long as there is still a base OS installed. You can reboot and do a completely clean install with the upgrade discs...as long as there is a base OS still present on the HD...you can even wipe the HD once it verifies an eligible license is present.

You know I've often wondered about the last part of what you said. I have always wondered how the disc knew if you had an eligible OS upgrade after you wiped it / rebooted then re-installed windows. Isn't the hard drive empty at that point? Or does it store a tiny bit of info after it formats the drive? Just the programmers curiosity coming out on that one :)

It stores that data in RAM if I remember correctly.

so technically if you wiped the drive and turned off the computer it wouldn't remember the information. Lets hope we don't get a power outage while upgrading with a clean install :) But thanks for the heads up. That question has been quietly nagging at me for years I've just been too lazy to look it up.

Exactly. That's how it is supposed to work. I've never tested that scenario. However I do believe if you've wiped the drive, but started the install process that's one of the first piece of info that gets committed to the drive. So it should still allow you to complete the install as long as it had started.

from personal experience the upgrade product keys will work on anything, they don't check if you already have anything installed or not, and they let you clean install. It might not be morally right for some to not pay full price, but charging 40 bucks is the only way you'll get some people to pay for windows at all, so it's an effective strategy in it's own right. Just buy the upgrade and be happy. If you want to be really evil, you can tell them you bought a netbook after June 2012 and get it for 15 bucks. I did that with one of the three product keys I purchased. I had a netbook with product key ready though when I found out I didn't need a product key.. I was just going to lie on the date I purchased said netbook.

Ive not read this whole topic(Don't have time its huge) but I have now for the third time activated windows 8 pro with a upgrade key by installing it in a hard drive with a NONE activated copy of windows on it. I formatted the drive in the setup and windows was activated immediately after installation.

Easy.

I am eligible for the upgrade anyway so don't see a problem.

Too bad you didn't read the thread. You would have found multiple posts where I pointed out that what you did is normal and has pretty much always worked.

;)

Sorry just thought Id help anyone out if it hadn't been noted. I did however on one install get a message saying this key is not for clean installations. Had to format and install again. Think it was because I didn't enter the correct key in the setup but rather I used one I got off the internet so I could verify windows 8 ran ok on the said computer first. Loving windows 8 now Ive got used to it.

    • I like Tidal, but it still does not control devices from the mobile/app and still no surround support. And yeah re: above comment I still get a lot of network errors and I am on a 4/4 Gbit Fiber connection.
    • Aren`t "security features" and "AI model that can see your screen" a tad diametric!
    • Samsung, Amazon extend 990 PRO 2TB NVMe SSD deal beyond Prime Day 2026 by Sayan Sen Recently, we had Amazon's Prime Day 2026 sales wherein there were several great deals including on SSDs. One of those discounted components was the Samsung 990 PRO SSD as the 2TB variant of it was selling for $370, a very good price after a long time. Although that deal was supposed to expire today, Amazon has now extended that sale further (purchase link under the specs table down below). The 990 PRO is a PCIe Gen4 NVMe SSD and still one of the fastest drives available today for under $400. Speaking of fast, sequential reads and writes are rated at 7450 MB/s and 6900 MB/s, respectively. The random throughputs for reads and writes are 1400K IOPS and 1550K IOPS, respectively. The 990 PRO is based on Samsung's 7th Gen V-NAND flash, and it too is TLC. It packs 2 gigs of LPDDR4 DRAM cache, which helps the random performance. The endurance rating for this is 1200 TBW (terabytes written), which should be sufficient for most users. The Samsung 990 PRO is compatible with the PlayStation 5, but if you are going to use the 990 PRO on a PC, check out the Samsung Magician app that lets you track your drive's health, update its firmware, customize various settings, and more. The technical specs of the Samsung 990 PRO 2TB are given in the table below: Specification Value Form Factor M.2 2280 Interface PCIe Gen 4.0 x4, NVMe 2.0 NAND Flash Samsung V-NAND TLC Controller Samsung In-house Controller Cache Memory Samsung 2GB Low Power DDR4 SDRAM Sequential Read Speed Up to 7,450 MB/s Sequential Write Speed Up to 6,900 MB/s Random Read (4KB, QD32) Up to 1,400,000 IOPS Random Write (4KB, QD32) Up to 1,550,000 IOPS Random Read (4KB, QD1) Up to 22,000 IOPS Random Write (4KB, QD1) Up to 80,000 IOPS Operating Temperature 0°C to 70°C Reliability (MTBF) 1.5 Million Hours Endurance 1,200 TBW (Total Bytes Written) Get it at the link below: Samsung 990 PRO SSD 2TB NVMe SSD (MZ-V9P2T0B/AM): $369.99 (Sold and Shipped by Amazon US) Good to know This Amazon deal is U.S. specific, and not available in other regions unless specified.
