Didn't work for me. Crashed at about 50% in the creating media step. Disk usage in task manager spiked to 100% just before it failed.
Doesn't make sense why it would work because you're trying to write to the disk that has the creation tool running on it. It has to wipe the USB drive before it can install the setup bits to the flash drive.
I've done this a lot of times over the last year. Just wanted to get a newer copy of 1709 on the drive than the one I had a couple months ago. Now it won't create the flash drive.
Tried two different PCs and three different browsers. No Joy.
Frustrating...... :(
