This is the status of my laptop after the windows update which fkd up volume drivers on most other similar families of laptops

Equipment not Working:

Also, my MS office licence got blocked, so may have to buy it again.

Tried the following solutions:

- BIOS update

- Driver Update

Everything else got changed except the aforementioned problems.

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help,  I have a few troubleshooting steps we could try to fix the issue:  

Firstly, perform Windows Update and HP Support Assistant: ( do not skip any troubleshooting steps if you feel steps are repeating ) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

1. To open HP Support Assistant, double-click the HP Support Assistant icon .
2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
3. Click Check for updates and messages to scan for new updates.
4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
5. Click the update name for a description, version number, and file size.
6. Select the box next to any updates you want to install, and then click Download and install.

And, also run BIOS Update: Follow steps from the link: https://support.hp.com/in-en/document/c00042629

Thank you for posting back. 

I have a few troubleshooting steps we could try to fix the issue:  

Let's try Bios Recovery using a keypress combination:

1. Turn off the computer, and then connect the power cord.
2. Press and hold the Windows key and the B key at the same time, and then press and hold the Power button for 2 to 3 seconds.
3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

If this recovery method fails, use another working computer to create a BIOS recovery flash drive to install the latest BIOS file.

Manual key based recovery did not work.

Does this apply to my pc? "Reset the CMOS"

I mean the recovery was successful and without errors, but it did not change anything on the original problem.

Thank you for posting back.

The last thing I can suggest trying is a restore back to the factory. Performing an HP system recovery (Windows ) While doing the recovery there is an option to backup your personal files. If you have not previously done one now is a good time. 

Restoring Files that were Backed Up Using HP Recovery Manager (Windows )You can also contact HP support for assistance.  

The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system.

• Click here: https://support.hp.com/in-en/document/c06162205 to Use the HP Cloud Recovery Tool (Windows 10)

I doubt if this can make a difference, except spoiling few software licences. I believe the problem is with the control chip for all these functions, as I neither see drivers nor any signs of hardware (wifi, bluetooth, speakers and mic) detection on the Device Manager or windows.

Screen controls are also missing from every corner they could be present, changing power plan does not change the screen brightness. So far you have been suggesting the common repair steps.

I'd request you to suggest troubleshooting steps to identify the issue, rather than throwing solution KBAs on me.

Thank you for posting back. 

Apologize for the inconvenience caused,

As you've mentioned that the multiple issues started after a windows update, therefore we started performing software related troubleshooting steps in order to isolate the issue. Hence I would suggest reinstalling the clean windows OS will determine the failure. However, if its a hardware related issue with the computer then you need to service the computer. 

Keep me posted for further assistance.
