Windows 8 setup asks for the product key at the beginning of the setup without letting you install it.

I got the Windows 8 ISO from MSDN but I didn't get enough keys to install it on all my 7 computers. Also, my MSDN subscription level doesn't allow me to get the VL product key to Windows 8 Enterprise.

Is there any way I can install Windows 8 for a limited time period like we used to do for Windows 7 ?

  1. Create a bootable USB flash drive to install Windows 8.

  2. Navigate to <FlashDrive>:Sources

  3. Save a file called ei.cfg in that folder with the following text:

If you want to install the Pro edition, replace Core with Professional. If you want the setup to ask which edition you want install without entering the product key, leave the [EditionID] blank.

You can also set [VL] (Volume Licensing) to 1 (for true) and [Channel] to OEM/Retail

Now install as normal and the Windows 8 setup won't ask for the product key. This will work for every copy of Windows 8 that you can get from anywhere.

Also, if you ever to want to enter the product key, you can do so from the Windows Activation window or using the slui 3 command.

The answer of User is correct, but you can also leave EditionID in ei.cfg blank:

Now Windows 7 and 8 Setup will let you install without Product Key, and also lets you choose the Edition you want to install. You don't need to edit ei.cfg every time.


Quickest option (no need to modify and burn a DVD or create an install flash drive) is to use a generic key. They are keys that can't be used for activation but only to bypass that installer screen.

Here is a list of generic keys. If the link is dead just Google windows 8.1 generic key.

MSDN keys are multi-activation which is why they don't provide you with a bunch.

I have read that at some point they will cut you off but then all you need to do is just call them up and they very lenient about resetting the count.

A few days ago, I happened to came across an interesting question while browsing Microsoft support forums. A PC user wanted to know the edition and version of Windows a product key belongs to, so that he can download and install the right version and edition of Windows on his PC.

Let us assume that you have a bunch of Windows product keys but you are not sure the version and edition they belong to. Although it’s possible to try them on virtual or physical machines, the approach doesn’t make sense when you have a bunch of keys, and especially, if you are not sure if they belong to Windows 7, Windows 8 or Windows 10.

That said, if you know that a particular key is for Windows 10, then you can determine the edition of Windows 10 the key belongs to by entering it on a PC running Windows 10 as there are only two editions: Home and Pro. Once the job is done, you can uninstall and deactivate the key if you wish to do so.

Determine the version and edition of a product key

Luckily, there are a couple of ways out there to easily determine the version and edition of Windows a product key belongs to. You can use one of the given below utilities to check version and edition of Windows you can activate using the product key.


ShowKeyPlus is a free software designed to retrieve product key from registry, BIOS/UEFI, and Windows.old folder. In addition to that, the tool can be used check the version and edition of Windows a product key belongs to.

Here is how to use the ShowKeyPlus software:

Step 1: Visit this page, download the latest available version, extract the zip file to get ShowKeyPlus.exe file, and then run ShowKeyPlus.exe with admin rights.

Step 2: Once launched, click the option labelled Check product key.

Step 3: Enter or paste the product key that you want to know the version and edition of Windows the product key belongs to. The version and edition of Windows operating will be displayed just below the product key field.

Ultimate PID Checker

Ultimate PID Checker is another free tool out there to determine the version and edition of Windows a product key belongs to.

Ultimate PID is not as superior as ShowKeyPlus, as Ultimate PID Checker requires you select a version of Windows to know the edition, unlike ShowKeyPlus which easily displays both version and edition upon entering a product key. That is, with Ultimate PID Checker, you might need to do trial and error to know the version of Windows operating system a product key belongs to.

Step 1: Download Ultimate PID Checker from here, extract the RAR file either using 7-Zip or WinRAR, and then run the executable.

Step 2: Select the version of Windows operating system that you believe the product key belongs to, enter the product key, and then click Go button to know the edition of the product key.

If the product key entered doesn’t belong to the selected version of Windows, you will not see the edition it belongs to. In that case, select another version of Windows, and then click Go button again.
