Many people are testing free versions of Windows 10 on their computers to help Microsoft improve the Windows 10 operating system.
These previews are regularly updated by Windows Update, but several users who use Windows 10 Insider previews have reported problems downloading new versions. You cannot see the new preview versions in Windows Update. Windows Update indicates that your device is up to date and no new updates are available, even if you are using an older version of Windows 10.
If you also have this problem and the new versions of Windows 10 do not appear on your computer with Windows Update, the following steps will help you to solve the problem and download the RTM version without problems.
