Windows 10: I can't find my Windows 8.1 Pro product key

I bought Windows 8.1 Pro from Microsoft Store web page on 2014 Aug 31. When I just bought it, I could see the product key from the purchase history page, but now it doesn't show anything but just 404 error-like stuff only.How can I find the product key? When I clicked the product name, it redirects to https://www.microsoftstore.com/store/mskr/ko_KR/pdp/productID.288586000, which is unavailable now.

I don't think that tool asks for a key if you are running the version of Windows you are trying to download the ISO for.

 

Windows 8.1 Product Activation with Windows 8 Upgrade Key

Is this where you got the Key?

Key Management Services (KMS) client aws Server andpe

And which is to do with Volume Licensing.

To use the keys listed here (which are GVLKs), you must first have a KMS host running in your deployment.

Windows 8.1 pro + WMC key activation

So it will be fine installing 8.1 pro with a KMS key, then switch to my 8 pro key and it will activate ok?

Maybe a daft question but why can't you just install 8.1 pro with the 8 pro key, or is it different keys for 8 and 8.1? seems silly when 8.1 is a free update anyway.
