0x800f0955-0x20003:The resolution of the error code of Windows update

Error Code:0x800f0955-0x20003
Explain how to deal with this error code.When I tried to upgrade from old Windows to Windows 10, I got the following error.

WINDOWS 10 could not be installed.
Your PC has returned to the state just before installing WINDOWS 10.

0x800f0955 --0x20003
Installation failed in the SAFE_OS phase due to an error during the INSTALL_UPDATES operation.

I used Update Assistant for the upgrade.

The upgrade failed and I returned to the original old Windows. In such a case, it seems that it may be successful to create a Windows image on an external USB disk (8G or more) and install from there.

Select "Create installation media for another PC" to proceed with the installation.
