    Is there a way to prevent iPad users to update the iOS?

    We plan to use the iPad Air 2 with a validated system and want to be able to prevent users from updating the iOS after system validation.

    If the iPad never leaves your network, you can block Apple's update servers. Otherwise, I don't believe so. But I'm far from being an expert on the enterprise/education tools Apple provides.

    You can stop the automatic update at Settings > iTunes & App Stores > Automatic Downloads --> Updates = "off"

    But this won't stop the user from updating the iPad as the OP wanted.

    Now I'm not really that familiar w/ the iOS Restrictions (Parental Controls) - information HERE, but would suspect that update prevention might be an option - not sure - any comments? Of course, each iPad would need to be set, so not sure 'how many' are under consideration? Dave :)

    As iPads are now used in commercial aircraft cockpits I would imagine that Apple has a solution to this. The suggestions above can all, as far as I can see, be over-ridden by a user.


    Edit:an after thought. I wonder if the multi user functions I understand Ios9 has will help?

    First I've heard of multi-user features in iOS 9. It certainly wasn't mentioned at WWDC, and I'd have expected a lot controversy and media attention over that.

    If there is a way to prevent updates by users it will be under Configurator or one of the other MDM (Mobile Device Management) system. I've heard it talked about before on an tech-in-educational podcast, but the consensus was that it was nearly impossible to block an update (if you let students take the iPad's home); or that it was incompatible with their other goals. It's been a while, so I'm not absolutely sure.

    A true multi-user system will require large upgrades in hardware:
    * more system memory needed to keep user files, media, data, settings separated. Can you imagine 10 users in a 128 GB device (12 GB per user)?
    * a much larger battery due to the device being in use for longer periods of time
    * iOS would need an overhaul, including a new log in screen (including user name AND password) since the device wouldn't know which user is holding it

    The above points would increase the thickness of the device and I'm not sure Apple will like that. This simply isn't feasible for current devices due to the limited hardware.

    Well, as with all Apple updates, obviously rumour, but a quick search brings up many references between wish list and rumour. e.g.
    'The iOS 9-related rumors have been aplenty during the past couple of days, and a report earlier today keeps the ball rolling in suggesting that Apple is prepping support for multiple users in a future software update. Additionally, there could also be a very interesting dual-app viewing mode, and given that many iOS users have been hoping to see such features for a long time, this is arguably the most exciting iOS 9 tidbit to date.....'

    That is inevitable, whatever the reason but in these circumstances why?
    >* more system memory needed to keep user files...
    Only if you are turning it into a proper multi-user computer, which I don't think it is at present. If the apps and system are common, then surely it comes down to settings, which could be fairly minimal (i.e. some of them being general and others user specific) and cloud based? As for more memory, I have an, at the time, start of the art 20MB drive in a cupboard from some 25 years ago; soon 128GB iPads will probably be the minimum.

    >* a much larger battery due...
    I disagree if it is based on simple switching between users -e.g. myself, my wife, kids....

    >* iOS would need an overhaul, including a new log in screen...
    Fingerprint...?
