Sealing the VM is used within the Windows Guest OS via this command:
'C:\Windows\System32\Sysprep\sysprep.exe /oobe /generalize /shutdown'
or
'C:\Windows\System32\sysprep\sysprep.exe' (then: Select 'Enter System
Out-of-Box-Experience (OOBE)' and check the 'Generalize' checkbox)
Once Windows restarts, you should see your configuration applied to the OS.
When should I use the
/etc/ovirt-engine/osinfo.conf.d/xx.files.properties?

To change any of the properties you may need to.

One needs to set the OS properly within the VM New / Edit functionality for
this to work. Then one can choose Cloud-Init/Sysprep and a configuration
such as to set the Time Zone.
If the Guest OS is Windows, then Sysprep is used, if Linux then Cloud Init
is used.
