Install Windows 11 25H2 on Unsupported PCs Using One CMD Command — Keep All Files & Apps

There’s a certain moment when you feel your PC deserves more than what Windows 10 can offer—especially when you see the polished design, modern features, and refined performance of Windows 11. Yet, for many users, the journey stops abruptly at a single message inside the PC Health Check tool:

“This PC doesn’t currently meet Windows 11 system requirements.”

It feels unfair, doesn’t it? Your system may still be fast, stable, and capable, and yet it gets blocked because of TPM restrictions, old processors, or missing Secure Boot. What makes this even more frustrating is that Windows 11 runs perfectly well on hardware far older than what Microsoft officially supports.

Today, we are going to walk through a clean, safe, and beautifully simple method to upgrade from Windows 10 to Windows 11 25H2without losing a single file or application, and without modifying system files or using third-party patches.

Everything happens through one CMD command executed directly inside the mounted ISO.

Let’s begin.


Downloading the Official Windows 11 ISO (Latest 25H2 Build)

Before we do anything else, we start with the ISO — downloaded only from Microsoft’s official website. This ensures stability, security, and full compatibility.

Open your browser and search:

Windows 11 ISO download

Click the first official Microsoft link.
On the page, scroll slightly until you find “Download Windows 11 Disk Image (ISO)”.

Now follow these steps:

  1. Click Select Download.
  2. Choose Windows 11 (multi-edition ISO).
  3. Select your product language (keep it consistent with your current Windows).
  4. Click 64-bit Download.

Your PC will begin downloading the latest stable Windows 11 25H2 ISO.

This is the same file used for genuine upgrades — meaning the process stays official and predictable.


Mounting the ISO and Opening CMD in the Correct Directory

When the ISO finishes downloading, right-click the file and choose:

Mount

Windows will create a virtual drive (let’s say E:). Inside it, you will see:

  • setup.exe
  • sources folder
  • boot files

Now move to the top search bar of File Explorer (within the mounted drive).
Delete everything written there and type:

cmd

Press Enter.

This instantly opens Command Prompt in the ISO’s root directory, saving you from manually navigating folders. You’ll notice the CMD path already shows:

E:\>

(or whatever drive letter your system assigned).

To verify file visibility, type:

dir

CMD will list all files inside the ISO — including the important:

setup.exe

Now we’re ready for the magic command.


Running the CMD Command That Bypasses All Requirements

This is the single line that triggers Windows 11 setup while disabling requirement checks, allowing upgrade migration, and keeping drivers intact:

setup.exe /product server /compat ignorewarning /migrate drivers all

What This Command Means — Full Explanation

Let’s break it down so you truly understand what’s happening:

1. setup.exe

Runs the official Windows setup program located inside the ISO.

2. /product server

This is the trick that unlocks the bypass.
It tells the Windows installer to run in Server Upgrade Mode, which does not enforce:

  • TPM requirements
  • Secure Boot
  • CPU model restrictions
  • RAM minimums
  • Storage minimums

It does not install Windows Server — it only uses the upgrade logic of the server setup engine, which is less restrictive.

3. /compat ignorewarning

This option forces the installer to ignore all compatibility checks, including unsupported hardware warnings.

4. /migrate drivers all

This ensures your current Windows 10 drivers are carried over safely into Windows 11 — critical for WiFi, Bluetooth, graphics, and sound to work after the upgrade.

This is why this method works beautifully:
It upgrades using Microsoft’s own tools, but with strict requirements gracefully bypassed.


Starting the Upgrade Process

After typing the command above, press Enter.

Within a few seconds, the Windows Setup window appears.
Interestingly, the top may say:

Install Windows Server

Don’t worry — this is because of the /product server flag. The final result will still be Windows 11 Pro / Home depending on your current edition.

Now continue:

  1. Click Change how Setup downloads updates
  2. Select Not right now
  3. Click Next

Windows will begin checking your PC — but this time, every requirement is silently bypassed.

Click Accept when the license agreement appears.

Suddenly, the setup displays the screen every Windows 10 user wants to see:

Choose what to keep

  • Keep personal files and apps ✔
  • Keep personal files only
  • Keep nothing

Make sure the first option is selected so that no files or applications are removed.

Click Next.

Soon you’ll reach the Ready to Install page:

Install Windows 11 Pro
Keep Windows settings, personal files, and apps

This is your confirmation that the bypass worked correctly.

Click Install.

The system will restart several times as the upgrade completes.


After Reboot — Windows 11 25H2 Successfully Installed

When the installation finishes, you’ll return to your desktop — now powered by Windows 11 25H2 — and everything remains intact:

  • All files on the desktop
  • All folders in Downloads
  • Installed apps and software
  • Browser data
  • Documents, images, and personal settings

Even the ISO you downloaded will still be there.

No data loss.
No formatting.
No unsupported hardware errors.

Just a clean, official Windows 11 upgrade on a PC Microsoft said wasn’t eligible.


Final Thoughts — A Surprisingly Simple Path to Windows 11

What makes this method so elegant is that it relies entirely on Microsoft’s own setup logic. No registry edits, no patching DLLs, and no risky modifications. Just a single CMD command that guides the installer into a more tolerant upgrade mode.

If you were ever told your PC cannot run Windows 11 — this method proves the opposite.

Your hardware still has life in it.
And Windows 11 25H2 runs beautifully even on older systems.


Disclaimer

This method is safe when followed exactly as described. However, upgrading any OS carries inherent risk. Always keep a backup of essential files before performing major system updates. dtptips does not encourage modifying system files or unsupported tools — this method uses only official Microsoft installers.
