Windows 10 version 2004 "Your Device is not ready"

Download the  windows update assistant and update your OS. Here's the link: https://support.microsoft.com/en-ca/help/3159635/windows-10-update-assistant

This worked for me.

Guess what?   When Setup said my PC was not ready, it apparently wasn't ready.

I tried the Windows 10 Update Assistant work around.   Yes, it allowed me to start the update to 2004.    However, in the end, it finally failed.   I'll give kudos to Microsoft, in that the Update Assistant was able to return me back to 1909 with no ill effects.

I am still left wondering why, even after all these many months since 2004 was officially released, 2004 isn't yet ready for my PC.   I have done many feature updates over the years, without delays or problems.   So, I would say, my PC is rather standard.  No odd or unusual hardware and with that, no odd or unusual drivers (ie, I have all Win 10 drivers).

As others have said, it would be great if Setup also gave a REASON for not being ready.  The Update Assistant also left not a clue as to why if failed.  And Microsoft should at least tell me WHEN 2004 will be ready.

Just fyi, if someone has a similar issue than I had:

I identified the issue on my machine that seemed to cause the upgrade stop.

When I analyzed the software stack on my machine manually after not getting any meaningful info from MS, I noticed that the installed version of "8GadgetPack" was outdated (v29).

Since this tool was always inactivated during the last few win10 upgrades (I needed to update or at least reactivate the software afterwards manually), I thought that maybe the current version of the win upgrade tool might deal slightly different with this software.

So I applied the latest version (v33) of 8GadgetPack and retried the "Windwows 10 Update-Assistent" afterwards. 

This time the upgrade process worked. 

I again had to reactivate 8GadgetPack afterwards - the upgrade inactivated the software same way it also happened during the last few successful win upgrades. But that was all.

I still don't know why I had to find this out by myself, without any info of the assistent, since such a software incompatibility should be easy to report by a tool. Anyhow...

No.  When you clean reinstall 3 PCs amd each has different network problems, and all respond differently to attempts to make them see or be seen, you despair of Windows.  In the end, I shared the four main folders with everyone and did a network reset on all 3 at the same time. Most of the suggestions on Google, particularly starting services and changing them to automatic were useless.

Instead of treating each PC individually(one could not  be seen or see One could see and be seen by 2 (one itself), a third was perfect most of the time, then became erratic which caused my final, successful attempt.   

So synchronising sharing and a network reset solved my problem.

Thank you for your replies.  (all 3 pcs were on same up to date version of win 10)

I have four old (vintage 2008/2009) desktop computers and an old (vintage 2009) laptop.  Three of the desktops and the laptop are running Windows 10 Home Edition, and all took the Windows 10 Version 2004 feature update without any issues.  The remaining desktop is running Windows 10 Pro and it keeps getting the "not ready" message - I check it every day.

Based on this small sample, my guess is that the Version 2004 feature update isn't yet available for computers that are running Windows 10 Pro.

No, my Windows 10 Pro machines are running great.

It appears to me that you have isolated a thread of my problem, because I also have Windows 10 Pro - which was included in a Western Digital Solid State Drive upgrade. I do not know if it has anything to do with the problem, BUT that upgrade replaced my previous Windows 7 Home version. Conclusion: Microsoft has us users playing guessing games.   Thanks, Grant Collar

Your last reply makes good sense to me. Thanks for your research effort and replies.  Grant Collar

If anyone else in the world (with limited computer knowledge, like me) is reading this stuff, I looked up "NVIDIA":

It designs graphics processing units for the gaming and professional markets, as well as system on a chip units for the mobile computing and automotive market

I finally discovered what seems to be the reason why my old Windows 10 Pro desktop isn't yet ready for the Version 2004 feature update.  According to the information from the relevant "Learn more" page that accompanies the notice, in addition to a list of a bunch of yet unresolved problems, it seems that there are compatibility issues with some NVIDIA Legacy GPUs (link to the list: https://www.nvidia.com/en-us/drivers/unix/legacy-gpu/) .  My old desktop has one of them - NVIDIA GeForce 6150SE nForce 430.  The problem is being investigated, and Microsoft & NVIDIA are supposedly working on developing an update to fix it.

I hope this will be helpful to some of you.
