Dear Experts,

How to setup Windows 11 25H2 without connecting pc to internet as the option bypassnro is no longer supported in OOBE.

We need to setup the pc without connecting it to internet as this will be used as base for creating the new wim file.

Thanks for your help

A clean install of 25H2 works exactly the same way as it did in 24H2. There's mass confusion on the Internet, which MS probably intended.

At some point the BypassNRO.cmd script will disappear, but the BypassNRO registry hack still exists. If you have a Local Account defined in the unattended file, or add the BypassNRO reg key during the specialize pass, you don't need to create a MS Account.

If you're building a new WIM, there are two options:

1. Create an autounattend.xml to create a Local Account, or apply the BypassNRO key.

Code: 
<?xml version="1.0" encoding="utf-8"?>
<unattend xmlns="urn:schemas-microsoft-com:unattend">
    <settings pass="windowsPE">
        <component name="Microsoft-Windows-Setup" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <UserData>
                <ProductKey>
                    <Key></Key>
                </ProductKey>
            </UserData>
        </component>
    </settings>
    <settings pass="specialize">
        <component name="Microsoft-Windows-Deployment" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <RunSynchronous>
                </RunSynchronousCommand>
                    <Order>1</Order>
                    <Description>Bypass Microsoft Account sign-up</Description>
                    <Path>reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE /v BypassNRO /t REG_DWORD /d 1 /f</Path>
                </RunSynchronousCommand>
            </RunSynchronous>
        </component>
    </settings>
</unattend>

2. Mount the image, load the offline SOFTWARE reg hive and apply the BypassNRO key (without an unattended file).

Code: 
DISM /Mount-Wim /wimfile:D:\path\to\image.wim /index:1 /mountdir:C:\Mount
reg load HKLM\TEMP C:\Mount\Windows\System32\config\SOFTWARE
reg add HKLM\TEMP\Microsoft\Windows\CurrentVersion\OOBE /v BypassNRO /t REG_DWORD /d 1 /f
reg unload HKLM\TEMP
DISM /Unmount-Wim /mountdir:C:\Mount /commit

OOBE\bypassnro still worked with build 28020.1362.
I tried a clean install with the ISO created from uupdump on Dec. 22, 2025.
I had no problem installing without internet connection and with local account.
Perhaps Microsoft reversed the decision about removing that option. 🤞😵‍💫🤷‍♂️

I would be careful about trying to draw conclusions based on a pre-release build.

Sometimes BypassNRO stops working in them, and sometimes it returns after a while. MS has more or less stated that the BypassNRO.cmd script will disappear, without admitting that it will close the underlying loophole (which can be served by applying the reg key outside of the script).

Not making any conclusion.
Just stating the facts.
That option still worked with 26200.7171 public Build. I have not tried with latest 26200.7462 yet.
I'll post back after I try it out. 😎
Edit:
I just tried with latest MCT made, public Build 26200.7462 and oobe\byapssnro still works with that too. 😉

Anyway, there are other documented ways for installing without internet and/or using a local account.

A new way to create a local user account - better than oobe\bypassnro

Since the ability to use oobe\bypassnro is going away in 2025, here is a new way to create a local user account. This is even easier than oobe\bypassnro. At the point in setup where you would run oobe\bypassnro, from a command prompt run: start ms-cxh:localonly Love this method. Best method...
