Windows 11 reached end of service

Anonymous

Down in the system tray, it shows "Your version of Windows 11 has reached end of service. Click to download a newer version of Windows 11 to stay updated."

When I click on it, the Windows Update window opens. Its states You're Up to Date but under it, it shows "Your device is missing important security updates. Make sure to keep device on and plugged in so updates can complete.

I am not sure how to resolve.

Current installed Windows info is below

Hi Ron, I'm John, a fellow Microsoft user like you.

I understand your frustration, and I’m here to help. From what you’ve shared, it seems like you're using Windows 11 version 21H2, which reached its end of service as of October 8, 2024. This means it no longer receives security updates or support. Reference: https://learn.microsoft.com/en-us/windows/relea...

To get your device up to date, the best course of action now is to perform a Repair Upgrade. This process upgrades your system to the latest version of Windows 11 without affecting your personal files or apps.

Here’s how to do it:

> Download the Windows 11 Installation Assistant from the official Microsoft website: https://www.microsoft.com/en-us/software-downlo...

> Open the tool and follow the on-screen instructions to upgrade your PC.

> Make sure to choose the option to Keep personal files and apps.

> Ensure your device stays plugged in and connected to the internet during the process.

For more detailed guidance, you can also refer to: https://answers.microsoft.com/en-us/windows/for...

This should resolve the issue and get your system updated to the latest supported version. If you need further assistance, feel free to reach out.

I think the CPU is unsupported for 24H2. Please verify this by visiting these links.

Install the 23h2 Enablement Package:

https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/caa3ff4a-6420-4341-aeae-33b2d7f463be/public/windows11.0-kb5027397-x64_3a9c368e239bb928c32a790cf1663338d2cad472.msu

Greetings

Installing the 23H2 Enablement Package that @Tekkie Boy recommended worked for me.

I am on a little older Dell Optiplex 7040 that I did a clean install of Windows 11 on a while ago using the Media Creation Tool but just recently I noticed Windows telling me my version of Windows (21H2) was now unsupported. When I ran the Windows 11 PC Check tool it flagged the system for both TPM 2.0 and the processor (6th Generation Core i5-6600).

After checking Dells support site I was able to get a firmware update utility to get my TPM updated to 2.0 software wise but Windows 11 only supports back to 8th Generation Core processors and Windows still wouldn't update.

However, after installing the 23H2 Enablement Packaged linked above and then a quick reboot - I hit Windows Update and it immediately started downloading/installing the 23H2 update without any further complaining. It appears now I am fully up to date... at least for now!

Glad to hear that.

To see if there is a 24H2 safeguard hold for your system, please do the following:

Open an admin Command Prompt and run this command:

CompatTelRunner.exe -m:appraiser.dll -f:DoScheduledTelemetryRun

Wait for 2-3 minutes for the task to complete execution.

Then, run this command:

REG QUERY "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\TargetVersionUpgradeExperienceIndicators" /s

Post the output here.
