Media Creation Tool Error Code: 0x80070143 - 0x20000

Hi,

Are you using the Media Creation Tool on Windows 7 or Windows 8/8.1?

This error is due to the TLS 1.0 protocol. If you are on Windows 7, you need to update to SP1 and perform this procedure: first, access the Start menu > Control Panel > System > System Protection > Create a restore point and give it the name you want.

After you open Notepad, paste the code below and save it as a .reg file:

`

Windows Registry Editor Version 5.00`

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp] "DefaultSecureProtocols"=dword:00000a00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Internet Settings\WinHttp] "DefaultSecureProtocols"=dword:00000a00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client] "DisabledByDefault"=dword:00000000 "Enabled"=dword:00000001

`

Execute the registry file and restart your PC and test again.

If you want to create a Windows 10 or 11 installation drive, you can use an alternative like Rufus and download the ISO from the official Microsoft website.
