Unable to install 24h2 windows update

Hi Ishwar Rajput,

Thanks for contacting us. I understand you're having trouble upgrading your Lenovo ThinkPad device from Windows 23H2 to 24H2, even after reimaging. Let's walk through a few steps to help resolve this.

What Might Be Causing the Issue

Windows 24H2 is currently being rolled out in phases and may not yet be available for all devices via Windows Update. Additionally, some enterprise environments or OEM configurations may delay availability depending on compatibility checks or update policies.

Recommended Steps to Proceed

1. Check Windows Update Eligibility

• Go to Settings > Windows Update and click Check for updates

Ensure the device is connected to the internet and not restricted by update deferral policies

2. Verify Update Policies

If you're using Group Policy or Intune, check whether update deferrals or version targeting are preventing 24H2 from appearing

Look for any configured TargetReleaseVersion settings that may be locking the device to 23H2

3. Use the Windows Installation Assistant or ISO

If the update isn’t available via Windows Update, you can manually install 24H2:

Download the Windows Installation Assistant or Windows 24H2 ISO from the official Microsoft Download Center

Run the installer and follow the prompts to upgrade the device

Be sure to back up any critical data before proceeding with a manual upgrade

4. Check Lenovo Compatibility

Visit the Lenovo Support site to confirm that your ThinkPad model is certified for Windows 24H2

Ensure BIOS and drivers are up to date, as outdated firmware can block OS upgrades

Additional Notes

If the device is part of a managed environment, you may need to coordinate with your IT admin to approve or deploy the update

If you're using a Teams Room configuration, confirm that the 24H2 update is compatible with your Teams Room software version

I hope my answer is useful for you.

Best regards,

Quinnie Quoc.
