The easiest way is to download the Rufus utility from rufus.ie, or WinSetupFromUSB from www.winsetupfromusb.com.
Or the official Windows USB / DVD Download Tool:
https://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool
The WinSetupFromUSB utility works without installing, so to say, “Portable”, run the downloaded file and click “Extract”, after which we will wait until the files from the archive are unpacked.
Go to the unpacked directory and run the file WinSetupFromUSB_x-x.exe or WinSetupFromUSB_x-x_x64.exe if you are using a 64-bit operating system.
In the utility window where “USB disk selection …” select the USB flash drive.
Below we indicate with a tick which Windows you want to burn and indicate its ISO image by clicking the “…” button.
Press “GO” and wait until the process is complete.
At the end, you get a ready-made bootable USB flash drive with Windows, from which you can boot on any computer.
