If you find that your Windows 10 is stuck on a particular version, which is now unsupported and will not upgrade, here are suggestions that will help you upgrade to the next version. When you hover your mouse pointer over the Windows Update icon in the Taskbar, you may see a message:
Your version of Windows 10 would reach the end of service soon, Click to download a newer version of Windows 10 to stay supported.
An unsupported version of Windows will no longer receive software updates from Windows Update. These updates include security updates that can help protect your PC from harmful viruses, spyware, and other malicious software which can steal your personal information. Windows Update also installs the latest software updates to improve the reliability of Windows—such as new drivers for your hardware.
If you are unable to get the next or latest Feature Update downloaded and installed on your computer via Windows Update, you have the following options.

Having done this, follow these suggestions:
1] Run Setupdiag Tool from Microsoft
Download and run Setupdiag. SetupDiag is a standalone diagnostic tool that can be used to obtain details about why a Windows 10 upgrade was unsuccessful. It works by examining Windows Setup log files to determine the root cause of a failure to update or upgrade the computer.
Once the scan is completed, check the generated log files. The SetupDiagResults.log will be geretaed and saved in the same folder where you downloaded Setupdiag.
Open SetupDiagResults.log using Notepad. You may need to take a look at these folders:
If there are any issues or conditions that are blocking the upgrade, they will be listed here.
2] Edit TargetReleaseVersionInfo Registry key
Open Registry Editor by typing Regedit in the Run prompt (Win + R), and then press the Enter key
Locate two DWORD files and set the value as below. If they do not exist, create them as follows:
The value should be the exact number as in the semi-annual channel list in the link above.
- Set the value of TargetReleaseVersion to 1
- If you are stuck on, say, Windows 10 1909 and want to upgrade to Windows 10 20H2 now, you need to set the value for TargetReleaseVersionInfo to 20H2
Followed by this, you will have to restart the computer. Once the reboot is complete, log in and go to the Windows Update, and check for the version of the update available to download. Once installed, it will remain on this version.
Using this registry key, you can also stop Windows 10 from upgrading to next version and Set the target Feature Update version.
3] Windows 10 Update Assistant
Another option you have is to upgrade your Windows 10 version to the next one using Windows 10 Update Assistant.
