Yes Integ1978 , this is a huge problem for us also. We currently have a couple of dozen units spread across our workshop which we've been trying to update all week. Although they are slowly getting there, with some coaxing, this is day 4 for this batch and they need to ship to site tomorrow, so will be going whether they are ready or not. Then we have another 4 pallet loads for the same project. We've updated all of these once already, when they arrived some months back.
I also have one of my engineers sitting around on a remote mine site, 2000km from home, who can't start commissioning the systems he's up there to do, as he's busy trying to get the MTRs up to date. He fly's home tonight, which will mean a return visit (i.e. $thousands).
Microsoft people, if we can get the current ISO from our manufacturer, is it ok to setup a system to image the units via PXE and/or USB? This would save a lot of time and grief.
