You can download a 7/8.1/10 ISO from Microsoft using this tool: http://www.msfn.org/...load-tool-4-00/
Later you can add all required files/folders to make that ISO or USB good for all OEM brands using the tool Project Only - No Query Tool [29.70 MB] from the links in this page: http://pasted.co/de1acca8 read text files inside the download, it is pretty clear.

NOTE: This is only good for OEM machines, this DO NOT activate the OS unless there is the required Slic or Serial in your Bios (from OEM manufacturer), so make sure you download the proper OS, for your machine, you can download Query Tool Only [109.82 KB] in advance to check wich OS is good for your equipment. Some AV claim this one is malware but IT IS NOT, false positive.
