OSBuilder requires Admin Rights in PowerShell as you will be mounting Windows Images for Offline Servicing. This is a requirement of DISM
The OSBuilder PowerShell Module requires an OS Version of 10, which includes the following Operating Systems
- Windows 10
- Windows Server 2016
- Windows Server 2019
Using the OSBuilder PowerShell Module on Windows 7 or Windows Server 2012 will only cause pain, grief, and sorrow
OSBuilder will allow you to fully Update and Customize Windows 10, Server 2016, or Server 2019. Windows 7 and Server 2012 can be Updated but not Customized
Offline Servicing of an Operating System can take a considerable amount of time, especially on older releases. The process of Mounting a WIM, Applying a Cumulative Update, and performing DISM Image Cleanup will take as little as 30 minutes (1809 x86) on an Intel Core i7 computer with a SSD, to almost 2 hours (1607 x64) on the same system.
Since OSBuilder will mount Windows Images, I strongly recommend that you do not have any running Anti-Virus scanning files ON ACCESS. McAfee will prevent the dismounting of images properly.
OSBuilder works best on a stand alone Workstation Class computer. An AntiVirus performing On Access Scanning will interfere with mounted Windows Images. Alternatively, you can use a Virtual Machine as an alternate solution
