your device from an older version of Windows, such as Windows
7 or Windows 8.1, to Windows 10.
Before
searching for a specific error code, try the tips listed in General
fixes. If those don't fix your upgrade or installation problem,

Windows
Setup terminated unexpectedly due to another process running
in the background.
When
you start Windows by using a normal startup, several applications
and services start automatically, and then run in the background.
These programs include basic system processes, antivirus
software, system utility applications, and other software
that has been previously installed. These applications and
services can cause interference when you attempt to upgrade
to the latest version of Windows 10.
To
help you determine whether a background program is interfering
with the upgrade, a "clean boot" may be needed.
