Hello AtulSharma9,
I'm John an Independent Advisor and a Microsoft user like you. I'll be happy to assist you today. I understand you have a problem with Windows 2004 update not yet available on your device.
Microsoft is taking its usual gradual process to rolling out the upgrade, offering the upgrade in stages beginning with those whose devices Microsoft believes are the most likely to successfully install the update.
If you don't receive the update yet on your Windows 10 Pro PC, Microsoft possibly detect compatibility issues on your device, These holds are due to conflicts that could cause applications not to run correctly.
You can either wait for another month to let the feature update 2004 to mature and be more stable or Download the Windows 2004 ISO using media creation tool and try to upgrade manually.
Important: Back up your personal data and files to an external hard drive, USB thumb drive, or cloud location (such as OneDrive) before you begin any reinstall of Windows 10.

Download the Windows 2004 ISO using media creation tool and save it to your computer. Instructions inside the link.
Disable completely the internet on your computer, reboot the computer and install the iso.

It might take some time to install Windows 10. Your computer will restart a few times, Make sure you don’t turn off your PC.
You can reactivate the internet after.
