I'm trying to create Win10 installation media for a PC that shipped with Win10, but without a Win10 dvd. This PC must stay offline.
At a Win7 PC that was online, I tried to get an ISO image by running Microsoft's MediaCreationTool.exe Using the tool to create installation media (USB flash drive, DVD, or ISO file) to install Windows 10 on a different PC. But it looked like that tool was trying to upgrade that Win7 PC to Win10 (recall all those sneaky Windows Updates over the past few years). So I panicked and killed the tool.
When I search for how to burn a Win10 install dvd on the Win10 PC, or for where to get a Win10 iso, I end up at that same web page.
How can I build the iso from the offline Win10 PC? (If I run MediaCreationTool.exe there, it complains that the PC is offline.)
Or can I trust MediaCreationTool.exe to not mangle the Win7 PC?
