WIndows 10 Prep - Disable First Run "hi" on Base Image

In the right panel, find the Show first sign-in animation value and double-click it. Set it to Disabled to prevent the animation from showing. Note that this will also prevent Windows from asking new Microsoft Account users to opt-in to various Microsoft services at first run.

Windows 10 Home users will have to use the Registry to hide the animation. Type regedit into the Start Menu to open the Registry Editor. Then browse to this value:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

Once you’ve opened the System folder, right-click on the right panel and choose New > DWORD (32-bit Value). Give it the name EnableFirstLogonAnimation, then double-click it to change its value. Make sure it’s set to 0 to hide the animation.

Done.....
