    Hi there
    doing the upgrade first is always the best way -- in any case these days even on modest hardware these processes shouldn't take too long.

    DO BACKUP OLD SYSTEM FIRST in case things go horribly wrong though.

    If you want the latest build you can get it from UUPDUMP (not for Windows HOME edition or 32 bit versions) and create the iso --download and extract the script and run it - that should create your iso for you. You can use RUFUS or whatever to make bootable USB for installing / upgrading Windows. If coming from W8.1 the ISO itself can be mounted as a virtual CD -- no software needed. With W7 you'll need a physical DVD / bootable USB or software for mounting virtual ISO's.

    This can then also be used on multiple computers - saves downloading MCT on each machine you want to upgrade.

    Cheers

    @Bree now If i were to go that method in creating a thumb drive using the media creation tool and making a custom install.wim and autounattend.xml that will practically eliminate downloading "upgrade this PC now" step? Am i understanding that correctly?

    I think Bree has the same idea that I would have. Use the MCT to create a standard Win10 usb for upgrading all the machines from 8.1. Once the upgrade is done and activation confirmed, mount your custom ISO and do a Repair Install which will overwrite the base Win10 and install your customizations and programs. On a decent connection, the download time is minimal. Good Luck.

    Yes, as mrgeek says, the idea is that you use the MCT to download once to make the usb and use that to upgrade each machine and get it a digital licence. After that you can do your custom install if required.

    The alternative would be to use the MCT's 'upgrade this PC now' option, but that would mean that each machine would have to download the full install files before the upgrade would begin. Making the usb install media first would save you all that extra download time.
