A bit of a long shot, this one... any help much appreciated!

My laptop came with Windows 8.1 pre-installed. At the time, like many people, I got rid of it ASAP in favour of a less abominable OS.

Now that you can upgrade it to Win10, I would like to retrieve it, though I guess that might not be possible. It was pre-installed (no CD or USB stick backup), so when I formatted the laptop it was gone. I have read that the key might be in the BIOS, though I think I flashed the BIOS when changing OS.

What I'd then like to do is take the key (if indeed it still exists) and transfer the licence to a separate PC. I don't really care about the laptop's licence - I can use Linux or whatever.

On the second PC I would then install Windows 8.1, before downloading the upgrade to Windows 10.

The final piece of the puzzle would be to get the upgrade on to a USB stick, licence intact, for installation on a third, new PC, which is being built from scratch and has no OS.

A very roundabout way of getting free Windows 10 on a new PC, but if it's possible and you can tell me how, I will buy you 42393 beers. Not really of course - the man who'd go to such lengths to not buy Windows 10 would not do that - but I would be extremely grateful!

Failing all that nonsense, what's the cheapest way to go from having no Windows licences to having a full Windows 10 licence (Home would be fine, I think, but Pro preferred if cheap). I thought of buying Windows 7 basic then upgrading but can't find it anywhere.

Thanks!
 
The pre installed version of windows 8 on the laptop before you wiped in favor of another os.

Is what we call an OEM version the licence for that version of windows, it is tied to a single machine, or the one it was used on.

It is not transferable because it is matched to the physical hardware in that system.

Trying to use it with another system that has different parts and specs to the laptop will.
Not allow the licence key, even if you had it.

To be validated on an install on the other system because of the physical hardware changes..
It does not match.

This is a way of preventing you from using multiple copys of the same os to install on other computers or systems.

Thanks everyone - that was quick! I thought it might not be possible so I'll try to get a cheap Win 7 for upgrade. PC Part Picker options were a bit expensive, but there are things on ebay like this: http://www.ebay.co.uk/itm/Windows-7-Professional-32-64bit-Pristine-CoA-Label-Broken-Dell-PC-Free-Support-/172043549386?hash=item280e983aca:g:DkIAAOSwHPlWgQH9 for about £20.

Would it be advisable to go with one of these? If I go for that, then upgrade it, what would I do after the upgrade window expires in July, if for example I want to format the PC and do a clean install when I'm no longer able to install windows 7 again and upgrade free?

Didn't realise you can't post links, sorry! if you search ebay uk for "pristine broken dell" it's the first hit.

Also: IronSounds and BadActor - thanks very much for advice, after the first two responses it looks like despite those possibilities I wouldn't be able to do what I want. Interesting to know though!

Yes, after a bit more reading (sorry, should have done that first before asking here!) it looks like its a bit of a legal grey area, since OEM versions are intended only for the machine they were issued with - although apparently Microsoft are turning a blind eye. I did also find another one on Amazon UK sold by "softonlinehandel" - a German (?) company selling official refurbished Win 7 DVDs. The product has 83 5-star reviews out of 99 so I think I'll go for that. If I get it I'll report back for anyone who's interested.

Thanks everyone!
