Some issues after upgrading to Windows version 1809

[ChunGoh]

Hey everyone,

I have updated my Windows 10 to version 1809 from 1803, and immediately notice some issues. 

1. The audio outputs always have a short electric burst before the output is smooth again. Realtek HD audio driver is not updated delibrately, however, as I have noticed the latest version used up a lot of CPU. Is there a way to solve this? I believe the voltage input was suddenly turned up to the speakers, causing the burst before the amplifier stabilises it. Correct me if I am wrong, but if this is the case, this will shorthen the lifespan of my speakers. 
2. Windows update features a failure to install HP's HIDClass 2.1.8.1 driver, which I understood is a wireless button. The update is pushed from Microsoft server and upon checking, this is a driver from HP meant for Windows 1809 or above. Is there anyway to solve this? I know you can hide the update by installing a third-party software - not ideal at all. HP should be more specific to Mircosoft regarding whether this update is applicable to me or not. If applicable, why did it fail to install?
3. The rotation feature is no longer working. I managed to get it working after forced reset. Guess we can ignore this, but just putting it down for anyone interested.

Will appreciate any advice. Thanks!
