Hello dhanushmuniswamy,
I'm John an Independent Advisor and a Microsoft user like you. I want to apologize if you encountered this issue. I understand you have a problem with Windows 2004 update not yet available on your device.
Windows 10 Feature update 2004 won't immediately available for everyone because 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, Microsoft possibly detect compatibility issues on your device, These holds are due to conflicts that could cause applications not to run correctly. In the past few days/weeks, Users still experiencing problems after upgrading to version 2004. Give the update a month or two to mature. This will let the Feature update fix it's own problems through patches along the way and be more stable. I would not recommend you to upgrade manually because of this ongoing issues.
You can refer to this link for reference. You can monitor the known and resolved issues for version 2004.

Well, it's March 7th, 2021 and I've seen this message telling me "the May 2020 update is coming soon, keep looking for it here" in my Windows Update. Just out of curiosity, what it Microsoft's idea of "soon"? It's been almost a year and a new update was apparently released in November. I don't see an option to make it install now. Any tips?
