Windows 7 SP1

OSDBuilder (19.3.12) supports updating Windows 7 SP1 (version 6.1.7601.17514 or newer). Creating an OSBuild (Customized) is not supported

OSDBuilder has only been tested with importing and updating Windows 7 Enterprise with SP1 (February 15, 2011). If you do not use this version, expect inconsistent results. The ISO can be downloaded from MVLS (Microsoft Volume Licensing Service Center)

Import the ISO using Import-OSMedia. Do not use the UpdateOSMedia parameter, it is blocked for Legacy Operating Systems
