Windows 10: Volumne Lever not showing up

The Volumne Lever from the taskbar does not show up. an Explorer restart is necessary to resolve this isue. This bug has been minium since 2018. Why is not this bug fixed? The same applies to the unasked installation of a faulty sound driver (HD Graphics 520) in the course of a forced update?

For ordinary consumers, the system is hopelessly destroyed after the 1903 update. All open GL applications do not work anymore because of the installed display driver Visual Studio 2017 does not work anymore after the update. To resolve the problem i have downloaded the OEM display driver from ACER website site again.

Lumia 521 Shows Headphones for volumne

My Lumia 521 keeps using headphones for volumne. I was able to get it back to phone for a volume up to 10 and the app volume up to 30 yesterday but it then defaulted back to headphones.

Can anyone help me with this problem. My phone shows Windows 8.1/

Thanks.

 

when I create system Image, win10 find a wrong volumn

I have just one OS, is win10. but I have a hard disk and a SSD, and my win10 installed in SSD.

and error message, I click create system Image, and then choose volumn E, and then click next button. and the next step is to choose volumns which I want to backup, and the image in my quetion is the next panel screenshot. and my OS language is Chinese.

the image means :

volumn ( C: ) ( SYSTEM ) size: 58.85GB

volumn ( H: ) size: 277.17GB

volumn ( F: ) ( SYSTEM ) size: 277.17GB

volumn ( G: ) size: 277.17GB

C and F are system volumn, and default selected, and can't unselect.

but volum F is my soft volumn, not system volumn. I want to unselect F: and only backup C:

 

increase speaker volumn

I have read somewhere there is an app to increase the volumn of the 920 speakerphone when conversing on the phone.

Current default max volumn is 10, which is just below what is enough.

Does anyone know of an app or perhaps a Nokia driver/fix that will increase the volumn when listening to someone on the telephone?
