Windows 10: I am stuck in Windows 10 21H1 after my laptop got corrupted last time

Help me! I'm stuck on Windows 10 21H1 19043.899. Before my laptop got corrupted, my laptop only had my father's account.

After the laptop got corrupted, I had to reset it's factory settings. But after that i tried to join the Dev version, but it gave me an error code of 0x0800bfa.

but at 15:41, it got fixed but It's not showing me an option, instead I'm kind of stuck in a loop. It only says You're good to go, but I don't see my channel names listed, might be I'm stuck on Windows 10 21H1 Beta channel forever!

Is it time for Windows 10 already?

Here's a good step by step guide on doing a fresh install.

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Windows Update Stuck

Updating my laptop which I haven't used for 6 months.
I go to Settings, Update and Security, and there are a list of 10 updates, 2 of which say pending install, the others say pending download. Left laptop on overnight and still saying the same this morning.
Ran Windows Troubleshooting Updates twice, both times found no problem.
Have good Wi-Fi signal. Have re-booted several times. Now stuck. Can you please suggest how I get round this please.
