1411504 2015-11-17 20:53:00 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.)

1411505 2015-11-17 21:14:00 You have to extract an esd file with the esd decryptor program, so it'll create an ISO Speedy Gonzales (78)
1411506 2015-11-17 21:29:00 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

1411507 2015-11-17 21:33:00 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

1411508 2015-11-17 21:46:00 Perhaps decryption is done during use. I don't know

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

1411509 2015-11-17 21:55:00 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:
6818

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

1411510 2015-11-17 22:00:00 Try this from here (superuser.com). 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).

1411511 2015-11-17 22:06:00 using install.win failed with errors ( tried that ) :) change to boot.wim and it works.

Heres teh latest, just had to make a USB as a laptop refuses to move on during an upgrade ( surprise) ;)

1411512 2015-11-17 22:18:00 Thanks Wainui - it worked a treat

I presume 10.0.10586 is the latest-and-greatest
