With the release of Windows 10 Creators Update, Microsoft will remove access to previous versions of the operating system from regular channels such as the Media Creation Tool and the Software Download page. In case something goes wrong or it turns out your system is not working well with the Windows 10 Creators Update, you need a sure way to go back to your previous version. Yes, Windows 10 does include the Rollback option, which you must perform within 10 days of upgrading, but not a lot users will know this. The best thing you can do right now, is prepare reinstall media for your current version. Users running older releases such as Windows 10 1507 and 1511 will need to use the Recovery Drive option in current versions. Microsoft no longer host install files for those versions. If you are currently running the Windows 10 Anniversary Update, version 1607, you have time.
Volume License Customers and active MSDN subscribers need not worry about this; you can still download older versions if needed from those respective services at anytime.
