On digging around I found https://softwaregeeks.co.uk/product/windows-10-pro/ offering W10Pro for £29.99, and on looking further found quite a few for less than a tenner! E.g. £3.99, £6.99 , £7.25, and many more.
From what I gather these give just the product key and for the software I'll have to go to http://www.microsoft.com/en-us/software ... /windows10 and download and create an installation DVD/flash drive, which I'd then use to install W10Pro on the virgin disk of my new desktop, when I get it.
Sounds straightforward enough, but I can't help feeling that at those prices there's got to be a gotcha, so am wondering if anyone has any experience with this approach.
Also, at those prices I'd quite like to upgrade my Windows 10 Home laptop* to W10 Pro, but there's a confusion of information about that, with some saying these product keys are only for "clean" installs and can't be used to upgrade, whereas some say using them for W10 Home -> W10 Pro works fine. I'd have thought it could well do, as there's no software difference as W10 contains everything, the product key just determining what features get turned on, but, again, I'm wondering if anyone has any experience updating a W10 Home system to W10 Pro with these cheapo keys, and what gotchas there may be ....
* It was bought with Windows 8 and auto-updated to 8.1 then 10, if that makes any difference.
