Windows 21H1 Im confused

Im on windows 10 pro 2004 insider Dev Channel build 21313.rs.prerelease.210209-1440.
How do I upgrade to version 21H1 without losing all my files and installed programs etc?
Do I have to upgrade in steps? Going from 2004 to 20H2 then to 21H1 or..?
I have NO updates in my windows update settings being offered now or in the past and I have been in the Insider program for at least 3 months now..it justs keeps updating my 2004 version with new builds..Not upgrading me to 20H2 or 21H1. Please let me know the easiest way to do this or if in your Opinion I should just stick with 2004. I really like to be on the Latest version of Windows possible. Ty.

Did you run the enablement package dated December 8?

KB5000736 Windows 10 Insider Beta Channel Build 19043.844 (21H1)

The KB5000736 Enablement Package allows you to go from build 19042 (v20H2) to 19043 (v21H1).

Hello Windows Insiders, today we are announcing Windows 10 version 21H1 as the next feature update for Windows 10. As part of today’s announcement, we’re also releasing 21H1 Build 19043.844 (KB4601382) to the Beta Channel.

We are releasing this build to the Beta Channel via our “seeker” experience in Windows Update. This means Insiders in the Beta Channel will need to go to Settings > Update & Security > Windows Update and choose to download and install 21H1.

21H1 Build 19043.844 includes all the fixes noted here as well as the following new features as highlighted in John Cable’s blog post:

Windows Hello multi-camera support to allow users to choose an external camera priority when using high end displays with integrated cameras.

Windows Defender Application Guard performance improvements including optimizing document opening scenario times.

We fixed an issue that causes a one minute or more delay when you open a Microsoft Defender Application Guard (WDAG) Office document. This occurs when you try to open a file using a Universal Naming Convention (UNC) path or Server Message Block (SMB) share link.

We improved Robocopy’s performance when copying files that total over 400 MB in size.

We fixed an issue that causes a WDAG container to use almost 1 GB of memory (working set) when the container is idle.

Windows Management Instrumentation (WMI) Group Policy Service (GPSVC) updating performance improvement to support remote work scenarios.

We fixed an issue that causes changes that the Active Directory (AD) administrator makes to user or computer group membership to propagate slowly. Although the access token eventually updates, these changes do not appear when the administrator uses gpresult /r or gpresult /h to create a report.

Once an Insider updates their PC to 21H1, they will continue to automatically receive new 21H1 updates through Windows Update using our servicing technology (like the monthly update process). Insiders who don’t choose to install 21H1 right away will continue to receive 20H2 updates until we move all of the Beta Channel forward to 21H1 in the coming weeks.

To check and see if you’re running 21H1, just type “winver” into the Windows search box on the taskbar. It should show as “version 21H1”.

For all the details on the 21H1 release – check out John Cable’s blog post.

Thanks,
BLB

Windows 10 Version 21H1 (OS Build 19043.899)

That, I'm afraid, is the price you pay for installing an Insider build. 21H1 has not been released to the public yet and the Release Preview may still have bugs. You are not the only Insider to see this....

KB5000842 Windows 10 Insider Beta 19043.906 21H1 and RP 19042.906 20H2 - post #48

See if any of the suggestions later in that thread will work for you.
