How to fix 0x80072f8f 0x20000 error

Error 0x80072f8f 0x20000 appeared when I ran the Media Creation Tool. With the last program I wanted to either upgrade from 7 to 10, or just create a Windows 10 installer. It didn’t work either way because of the error. Rebooted PC, updated drivers (though probably for nothing), ran SFC (hopefully correctly) – nothing works. It seems I can’t even reinstall the OS properly… yeah.

Solution

0x80072f8f 0x20000 is the bane of all users who want to quickly and easily upgrade to a newer Windows operating system. Fortunately, there are several methods that can save the user from this annoying error.

First, if you are trying to upgrade from Windows 7 to Windows 10, you need to activate support for TLS 1.1 and TLS 1.2 protocols.

Secondly, if you are just trying to create an Windows 10 installation media and you fail, and Media Creation Tool shows you error 0x80072f8f 0x20000, then you need to get rid of the invalid update files that were previously downloaded by the tool. These are exactly where the problem lies.

  • Press WIN+R→REGEDIT→ENTER.
  • Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client.
  • Change DisabledByDefault to 0 (create one if necessary).
  • Then go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client.
  • Change the value of DisabledByDefault to 0 (again, create it if necessary).
  • Go to C:Windows\SoftwareDistribution\Download via Explorer.
  • Delete all folders and files that are stored in this directory.
  • Invoke the Command line (admin) and run the command wuauclt.exe /updatenow.

Once you have done all of the above, the error 0x80072f8f 0x20000 will disappear.
