Windows 10 April 2018 Update: Here's what you can expect
Every time Microsoft releases a new feature update for Windows 10, you should build a new recovery drive containing the setup files for that update. You can use that drive to repair a damaged installation or to reinstall Windows on a new PC.
You can use the Media Creation Tool to create a bootable USB flash drive, as I describe in my installation FAQ. But I recommend a slightly different approach: Use the option to download the Windows 10 installer as an ISO file, and then use that file to make bootable installation media.
After the download is complete, you can double-click the ISO file to mount it as a virtual DVD drive and run Setup directly from the mounted drive. From that same File Explorer window, you can also create bootable Windows 10 installation media on a USB flash drive.
In addition to the ISO file, you also need a USB flash drive at least 8 GB in size. This process will delete all data on the USB drive, so back up any important files before proceeding. Then follow these steps:
Label the drive (including the version number) and keep it in a safe place.
