Windows 8.1 is a free upgrade to all Windows 8 users, but you normally can’t install Windows 8.1 with a Windows 8 product key. Luckily, you can get around this limitation if you really want a fresh install of Windows 8.1.

This is really good stuff, I have windows 8 but re-installing is always a pain because I can''t install 8.1 directly. Question:Why am I downloading windows 8? we just download it and do nothing with it.

Maybe can we also do the installation of Windows 8.1 with a default key from Windows ADK and then change it after the 1st boot at the product key prompt or on the desktop before online activation with the genuine Windows 8 key... Maybe. I don't know. I didn't realy try it yet. If somebody knows if it works or not don't hesitate to tell us.

There are several default keys around that can be used to install Windows 8.1 but why bother. It is much easier and quicker to install from usb and add ei.cfg before starting. You don't even need to add the first two lines which tell you what edition to install. If you leave them off you get a menu to select what you want. Just make sure it matches your activation key.

Chris says to create the usb key directly from the download but there is another approach you can take. You can save the download to an ISO and then later you can copy the ISO to a usb key. Just Google for the method or use the Microsoft tool called " Windows 7 USB/DVD Download tool". You can get it here Windows 7 USB/DVD Download tool. There is one trap with the download tool. You cannot create a 64bit usb key on a 32 bit system. If you need to copy a 64 bit windows ISO to a usb key then it must be done on a 64 bit windows system. However, a 64 bit system has no such limitations. It can copy both 32bit and 64 bit ISOs. Even though the name implies it is for Windows 7 it will work on Windows 8 and 8.1 and 8.1.1 ISOs and I believe also on a Vista ISO but not on an XP ISO if such exists. As for the 8.1.1 ISO, I am still a TechNet subscriber (but not for long now) and I downloaded that ISO and used a USB key to install it several times.

Interesting article, If you have 8.1 upgraded from 8 that had Windows Media Center installed, how will a clean install of 8.1 maintain the Windows Media Center, seeing that WMC is an add-on and not in the base OS. I had gotten the add-in Pack for free from Microsoft while they had a special offer the beginning of last year.

This only works with window 7 installed, it will not work with Vista or XP. This has been published on the web for some time you should give credit to the source. Also is you're going to post sometime like this you should try it out with all versions of windows. Partial info like this waste a lot of people's time in trying to get it to work.

There have been several items posted on how to download Windows 8.1 ISO using existing product keys. However OEM product keys DO NOT WORK. I wish someone would work out a way to use the OEM product key. I would sure like to have Windows 8.1 ISO (legally).

I haven't had to reinstall 8 yet, But I need to actually. What happens in this case? Does Microsoft already know that your license has this associated with that key?

For you WMC types. You need to re-enter the WMC key via "add features" after the install of Win 8.1 is completed. It's a bit of a pain but your win8 WMC key is valid on win8.1.

You should have received and email from Microsoft with the Windows 8 Media Center Pack product key.
- Open control Panel.
- Click on: Add Features to Windows 8.1.
- Click on: I already have a Product Key.
- Add the Windows 8 Media Center Pack product key.
It will authenticate the product key. If it accepts the key as valid, media player will start to install. The computer will go through an update process.
It took about 5 minutes for this process to complete. Make sure you have any open files saved because of the reboot.

I installed windows 8.1 using iso from torrent site and activated using my windows 8 key by phone activation method.
As this method when i try to download the setup downloader says "we cant connect at the moment. check your internet connection."
when i searched many answered it was due to the key that is blocked or blacklisted. but i dont know how my retail windows 8 key gets blocked?.
is there any workaround to download official iso using this key by doing any kind of patch or like proxie stuff or to get rid of this key checking procedure?.
