How to bypass the Unattend screen in Windows 8.1 Update

In Windows 8.1 with KB3065988 installed, the system prompts users to reserve a copy of Windows 10 as part of the OOBE process that occurs at the first startup cycle. For organizations that are deploying Windows 8.1 Pro by using an Unattend.xml file that automates the OOBE process, this reservation notice still occurs. To suppress this notice, you can use either of the following methods:

Use Group Policy
Set the following Group Policy setting to Disabled:

Computer Configuration > Administrative Templates > System > Logon > Show first sign-in animation

Change the Unattend.xml file
Add the following entry to the Unattend.xml file for Windows 8.1 Pro x64

<settings pass="specialize">
        <component name="Microsoft-Windows-Deployment" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="" xmlns:xsi="">
                <RunSynchronousCommand wcm:action="add">
                    <Path>reg.exe add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v EnableFirstLogonAnimation /d 0 /t REG_DWORD /f </Path>
