Windows 11 on ARM can run inside a virtual machine on compatible ARM-based computers. Virtual machines are useful for testing Windows features, running applications, and maintaining a separate Windows environment without replacing the host operating system.
When a new Windows 11 feature update becomes available, an existing ARM virtual machine may not immediately receive it. Compatibility checks, virtual hardware configuration, Windows Update issues, or insufficient storage can prevent the upgrade from appearing.
If you already have Windows 11 installed in an ARM virtual machine and want to move it to version 24H2, you can normally use Windows Update first. If the update is not offered, other upgrade methods can be used depending on the virtualization platform and the current Windows installation.
Method 1: Check the Current Windows 11 Version
Before upgrading the virtual machine, check which version of Windows 11 is currently installed.
- Start your Windows 11 ARM virtual machine.
- Press Windows + R.
- Type:
winver- Press Enter.
- Check the Windows version shown in the About Windows window.
You can also open:
Settings > System > About
Look under Windows specifications.
Confirm that the virtual machine is already running a supported Windows 11 ARM installation.
Checking the current version first helps you determine whether the VM actually needs the 24H2 upgrade.
Method 2: Check for Windows 11 24H2 Through Windows Update
Windows Update is the simplest way to upgrade an existing Windows 11 ARM virtual machine.
- Open Settings.
- Select Windows Update.
- Select Check for updates.
- Install any available updates.
- Restart the virtual machine if requested.
- Return to Windows Update.
- Check for updates again.
If Windows 11 24H2 is available for your virtual machine, Windows Update should provide the feature update.
Follow the instructions shown on screen and allow Windows to restart the VM several times if necessary.
Do not shut down the virtual machine while Windows is installing the feature update.
Method 3: Make Sure the ARM Virtual Machine Has Enough Storage
A feature update requires free storage for downloading, preparing, installing, and temporarily storing the previous Windows installation.
Before starting the upgrade, check the available space.
- Open Settings.
- Select System.
- Select Storage.
- Check the available storage on the Windows system drive.
If the virtual disk is nearly full, remove unnecessary files before attempting the upgrade.
You can use:
Settings > System > Storage > Temporary files
Review the available categories and remove files you no longer need.
If your virtualization software allows the virtual disk to be expanded, increasing the VM’s storage capacity can also help when the existing virtual disk is too small.
Method 4: Install Pending Windows Updates First
Sometimes a feature update does not appear because the virtual machine has pending updates.
Open:
Settings > Windows Update
Install all available quality and security updates.
Restart the VM when required.
Then check Windows Update again.
You should also make sure that the virtual machine is connected to the internet and that Windows Update can communicate with Microsoft’s update servers.
If Windows Update repeatedly fails to install normal updates, resolve those problems before attempting the larger 24H2 upgrade.
Method 5: Check the Virtual Machine’s Hardware Configuration
Windows 11 ARM depends on the virtual hardware presented by the virtualization platform.
Before upgrading, make sure the VM is configured correctly and that the virtualization software is up to date.
Depending on your platform, check:
- Virtual CPU configuration
- Assigned memory
- Virtual disk capacity
- Virtual TPM
- Secure Boot configuration
- Network adapter
- Virtual firmware settings
- Guest integration tools or drivers
Do not randomly disable security features to bypass an upgrade requirement.
If the VM was created using an older virtualization configuration, updating the virtualization software and its Windows integration components may resolve compatibility problems.
Method 6: Use the Windows 11 Installation Assistant or Installation Media When Supported
If Windows Update does not offer 24H2, an alternative upgrade mechanism may be available.
However, ARM-based Windows installations require ARM-compatible installation media or an upgrade mechanism that supports the architecture.
Do not download an x64 Windows installation image and assume that it can be used to upgrade an ARM installation.
If your virtualization platform provides a supported Windows 11 ARM installation image, use the ARM version intended for your VM.
Before starting an in-place upgrade:
- Back up important files inside the VM.
- Shut down unnecessary applications.
- Connect the VM to reliable power if applicable.
- Make sure sufficient storage is available.
- Start the supported Windows 11 ARM setup.
- Follow the upgrade instructions.
- Choose the option to keep personal files and applications when offered.
- Allow the VM to restart during setup.
The exact installation process can differ between virtualization platforms.
Method 7: Update the Virtualization Software Before Upgrading
An older version of the virtualization application may not fully support newer Windows 11 ARM releases.
Check whether your virtualization platform has a newer version available.
Depending on the platform, this could include virtualization software running on:
- ARM-based PCs
- Apple Silicon Macs
- Other compatible ARM systems
Update the virtualization application according to the vendor’s instructions.
After updating the virtualization software, start the Windows 11 ARM VM again and check:
Settings > Windows Update
for the 24H2 feature update.
Also install any updated guest additions, integration tools, or virtual hardware drivers provided by the virtualization platform.
Method 8: Create a Backup Before the 24H2 Upgrade
A feature update normally preserves your Windows installation, but a virtual machine makes it relatively easy to create an additional backup before making major changes.
If your virtualization software supports snapshots or checkpoints, consider creating one before starting the upgrade.
You should also keep a separate copy of important files.
A useful backup approach is:
- Shut down the Windows 11 ARM VM.
- Create a backup or snapshot using the virtualization platform.
- Store important personal files separately.
- Start the VM.
- Begin the Windows 11 24H2 upgrade.
- Verify Windows after the upgrade.
A snapshot should not be considered your only backup for important data. If the VM files become corrupted or are accidentally deleted, a snapshot stored on the same physical drive may not provide adequate protection.
Why Is Windows 11 24H2 Not Showing in the VM?
There can be several reasons why Windows Update does not offer 24H2.
Common possibilities include:
- The VM has pending updates.
- There is not enough free storage.
- The virtualization software is outdated.
- The virtual hardware configuration needs updating.
- Windows Update has encountered an error.
- Microsoft has not yet offered the update to that particular installation.
- A compatibility safeguard is preventing the feature update.
Windows feature updates are not necessarily offered to every device at exactly the same time.
If Windows Update does not show 24H2, avoid forcing the update immediately. First make sure the VM and Windows installation are fully updated and properly configured.
Can You Upgrade ARM Windows Without Reinstalling It?
Yes, an existing supported Windows 11 ARM installation can generally be upgraded through Windows Update without performing a clean installation.
An in-place feature update is preferable when you want to preserve applications, settings, and personal files.
Always back up important data before a major operating system upgrade.
What If the 24H2 Upgrade Fails?
If the upgrade fails, restart the VM and check Windows Update for an error code.
You can also run the Windows Update troubleshooter if it is available in your Windows installation.
Check the following before trying again:
- Free storage space
- Windows Update status
- Virtual machine configuration
- Virtualization software version
- Internet connection
- Pending system restarts
If the VM has a recent backup or snapshot, you can use it as a recovery option according to your virtualization platform’s procedures.
Avoid repeatedly forcing the upgrade if Windows reports a specific compatibility block. Find and resolve the underlying issue first.
Check Windows 11 24H2 After the Upgrade
Once the upgrade finishes, verify the installed version.
Press:
Windows + RThen enter:
winverPress Enter.
The About Windows window should show the installed Windows version.
You can also open:
Settings > System > About
and check Windows specifications.
After confirming the upgrade, open Windows Update again and install any remaining updates.
Conclusion
Upgrading an existing Windows 11 ARM virtual machine to 24H2 is normally best handled through Windows Update. Before starting, check the current Windows version, install pending updates, make sure the VM has enough storage, and verify that the virtualization software is current.
ARM virtual machines require special attention to architecture compatibility. Do not use an x64 installation image for an ARM Windows installation. If Windows Update does not offer 24H2, check the virtual machine’s configuration, virtualization software, storage, and Windows Update status before trying another upgrade method.
Creating a VM backup or snapshot before a major feature update is also a sensible precaution. Once the upgrade finishes, use winver or Windows Settings to confirm that Windows 11 24H2 is installed.
