Hello all and sorry if posting this in the wrong place but recently I've needed to reinstall my windows 10 x64. I downloaded the media creation tool for windows 10 and whipped out my trusty ole 4gb usb stick.

Apparently it now requires 8gb to download and its 3am, i dont have a usb higher than that and I need my computer working by tomorrow morning.

After a few hours of fumbling around, I opted to download the windows iso instead using the media tool. The latest version as of december 2017 is 3.4gb.

Using the rufus usb tool, you can actually use the iso file and it will create a bootable usb even if it's less than 8gb like the official microsoft tool requires, so long as it's atleast 4gb, or rather 3.73gb in total. Even the webpage for rufus does not advertise this.

This is actually probably known by everyone who is more experienced than me with computers but during those few hours it took me to find this out, a lot of that was on google and I didn't see anything like this.

Anyways, if anyone ever stumbles scross this searching on google like I hoped to find, I hope this helps you all and thanks :)

Yea, this is true.  You don't even need rufus.  Just mount the iso, and copy all files to thumbdrive.
