Windows 11

Prepare a supported Windows 11 workstation for OSDeploy.

Use a fully updated Windows 11 25H2 amd64 computer as the OSDeploy PC.

Prepare the OSDeploy PC

1

Confirm the Requirements

Use a workstation that meets these requirements:

• Windows 11 25H2, build 26200 or later
• amd64 architecture
• Local administrative rights
• At least 50 GB of free space on the system volume
• Internet access to Microsoft, GitHub, PowerShell Gallery, Recast Software, and required hardware-vendor download services

Proxy servers and TLS inspection must permit PowerShell, curl.exe, and OSDeploy to download content from these services.

Windows 11 on arm64 can potentially be used, but it is not fully tested. Other Windows client versions and all Windows Server versions are unsupported.

2

Check the OSDeploy PC

Open PowerShell as an administrator and run:

$OperatingSystem = Get-CimInstance -ClassName Win32_OperatingSystem
$SystemDrive = Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DeviceID='$env:SystemDrive'"
$IsAdministrator = ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole(
	[Security.Principal.WindowsBuiltInRole]::Administrator
)

[pscustomobject]@{
	ProductName    = $OperatingSystem.Caption
	DisplayVersion = (Get-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion').DisplayVersion
	BuildNumber    = [int]$OperatingSystem.BuildNumber
	Architecture   = $env:PROCESSOR_ARCHITECTURE
	IsAdministrator = $IsAdministrator
	FreeSpaceGB    = [math]::Round($SystemDrive.FreeSpace / 1GB, 1)
}

Confirm that the output reports Windows 11 25H2, build 26200 or later, AMD64, administrative rights, and at least 50 GB of free space. ARM64 is possible but not fully tested.

Update Windows

Open Windows Update:

Start-Process 'ms-settings:windowsupdate'

Select Check for updates, install all available cumulative updates, and restart Windows when prompted. Repeat the process until Windows Update reports that the OSDeploy PC is current.

4

Enable Hyper-V

Enable Hyper-V now so its required restart is complete before building and testing OSDeploy boot media. Run this command on a physical Windows 11 Pro, Enterprise, or Education PC with hardware virtualization enabled:

Enable-WindowsOptionalFeature -Online -FeatureName 'Microsoft-Hyper-V-All' -All -NoRestart

Restart Windows after the command completes. See Microsoft Hyper-V for requirements and additional installation options.

Continue to Install PowerShell 7.
