    clean reinstallation on OEM machine and possible upgrade


    I may have to get a new laptop (see other thread in General...).

    When I buy a laptop with an OEM (home) version of windows 10 can I do a clean reinstall by using the media creatiom tool/iso route using the OEM key?

    Can the OEM Home version of Windows 10 be upgraded to Pro?

    In which order should these operations be performed?

    Thanks again in advance for any help.

    Yes, you can clean install. The license should already be active and registered automatically with MS and so you have nothing to do when clean installing, its all taken care of.

    The official upgrade route is here:

    I would imagine that once your PC is running Pro and activated that you can then clean install again at any time.

    Windows 10 Home-to-Pro upgrade isn't cheap if I remember rightly - if you were buying a new laptop it might be better to look for one with Pro already installed. Is there a particular reason you wanted Pro?

    win10 pro for bitlocker?

    The only reason would be bitlocker. But not sure that would have made the problem I am having now any less likely or any easier to solve.

    Some Windows 10 Home machines come with 'Device Encryption' which is a cut-down version of Bitlocker. The hardware has to meet certain requirements (such as booting from a non-rotational disk) - basically I think it's intended for tablets and laptops which might get stolen. But you're talking about a reasonably high-spec laptop, or a tablet to get that.

    I saw your other thread - I don't know the answer I'm afraid, although my first step would definitely be to de-crypt the disk if possible (is there a command line in option Truecrypt you could use?). Bitlocker has more chance of working than Truecrypt, although there was an update a couple of months back which broke my graphics driver so I had to type in the Bitlocker password 'blind' until I got it sorted. I gave up on Truecrypt when they didn't support Windows 8.
