Windows 10: My HP Victus Laptop can't update Windows 11 anymore

Hey, I have a laptop with a broken screen and ever since I've updated to Windows 11, I can no longer download updates from the Windows Update tab in settings. This also forbids me from using Microsoft Store in some way. I've tried things like factory resetting my laptop or downgrading to Windows 10, but repeatedly get denied every time I try. My laptop: HP - Victus 16.1" Gaming Laptop - Intel Core i5 - 8GB Memory - NVIDIA GeForce RTX 3050 - 256GB SSD Model Number: 16-d0013dx

Problem with Driver Realtek and Bang and olufsen (B&O) audio control panel Windows 11 (HP victus B&O)

I bought a laptop HP Victus 16-R0000 with B&O on Windows 11(

https://corporate.bang-olufsen.com/fr/partners/consumer-electronics/hp)

• BUT B&o audio control, HP audio control ⇒ "Impossible to connect to RPC service".
  
• Impossible to find Realtek HD Audio manager.
  
• All of that on Windows 11.
  

All my drivers are up-to-date (On hp website, Windows update, Microsoft store).

Hp told me that's a realtek problem, is the driver is not created? (in Windows 10 it worked perfectly)

Help me, please !

 

Problem with Driver Realtek and Bang and olufsen (B&O) audio control panel Windows 11 (HP victus B&O)

Hp never gave me the 2 B&O audio control, I found myself on Microsoft store earlier than they deleted it.

I had the B&O audio control on another hp laptop pavilion Windows 10.

I bought a new HP Victus without OS, and installed myself Windows 11 and all the drivers HP has for my Victus (but I saw all the people who upgraded win10 to win 11 lost the B&O app).

PS: Omen app is compatible with the hp Victus, but he not has all the functionalities for a real Hp Omen like rvb manager keyboard, audio manager and so on. And again I installed myself the Omen app (good cleaning mode, better than windows hard drive cleaner for example, or the famous changing hybrid or separated GPU/CPU mode).

Why I can't find simply the Realtek audio manager for my laptop?

 

I have HP Victus, came pre installed Win 11 Home, downgraded to win 10 Enterprise, now struggling with drivers, called HP and they suggested I speak with Microsoft,
