auto revert. i didnt do anything.
That is strange. The revert to previous version is buried in the settings and need user confirmation. I will be pissed if win 10 suddenly auto reverted back to win 8. Need to spend time to upgrade again.

I thought the licence key given for Windows 10 is different from the one you have for Windows 7/8.
So the old one will be invalid ah ?
I did a clean install of my Windows 10. No recover to windows 8 option![]()

isnt it obvious![]()
Well, let me rephrase, if you don't want the recover to windows 7/8 options. u do a clean install.The Win 10 license key (or product key) is probably generic. MS is relying on the hardware specs to determine activation status. The product key is not really that important.
As to whether the old license keys will become invalid after the 30 days period to revert has expired, there is no clear answer yet.
Think I'll hold on for a clearer answer.
you should reap on it before its iron sealed lol...

It's not generic. I used produkey program to extract the key out of my PC and as well as my brother's, both in Win 10 PRO. Both are different.
Are your Win 7/8 retail or OEM?
All 3 of my Win 10 Pros upgraded from OEM Win 8.1 Pro have the same product key VK7JG-NPHTM-C97JM-9MPGT-3V66T.
My 8.1 pro retail also give the same win10 generic key.

My 8.1 pro retail also give the same win10 generic key.
Contemplating to rollback...
Since your key is retail, you might want to consider rolling back to 8.1 Pro until there is some clarity on whether your upgraded Win 10 Pro can be transferred and/or whether you will lose the Win 8.1 Pro retail key.

Too late. You better don't rollback. There are problems with rolling back.
