    Default Win10 ISO on USB - any way to check version?

    I downloaded Win10 from a Microsoft site to a USB stick. I now want to check it's the right version before using it. Currently using Win7pro64 OEM

    I tried various 'dism' commands but it said the file wasn't found or was the wrong format. Windows Explorer shows the existence of a file called install.esd in a folder called sources

    (The Microsoft download site was rather lacking in information. It just said Windows 10. No date, no version number, no mention of 'November update', no link to more information.)

    You have to extract an esd file with the esd decryptor program, so it'll create an ISO

    I don't want an ISO as such. I intend to boot from the USB drive

    I feel sure there must be a dism command looking directly into the USB file system

    Well you can't boot from an esd file since its encrypted. You have to use the decryptor tool so it creates the ISO.

    You would still have to use something like rufus to create a bootable disk (from the ISO that ESD file creates). Unless you're going to mount the ISO after (and upgrade from within windows)

    Once the decryptor tool creates tha ISO it'll have a name. Type that name into Google it'll tell you what it is

    Perhaps decryption is done during use. I don't know

    Is it possible to tell from the dates that it's the November update?

    Heres how: from a admin command prompt ( or Powershell - Admin) type of copy paste the command

    dism /Get-WimInfo /WimFile:E:\sources\Boot.wim /index:1

    The Drive Letter E is what your USB drive will be that has windows on it, change to suit your drive letter:

    Arrow in screen shot point to the version

    Eg:

    Going by the picture you posted the Drive is K so your command would be:

    dism /Get-WimInfo /WimFile:K:\sources\Boot.wim /index:1

    Try this from here. Even tho that's for Win7, it maybe the same for Win10


    Click "Start", type "cmd", press "ENTER".

    Type or paste: dism /get-wiminfo /wimfile:"f:\sources\install.wim"

    (Replace f: with drive path to installer root).

    Thanks Wainui - it worked a treat

    I presume 10.0.10586 is the latest-and-greatest
