The missing option to convert files can be caused by changes made in your PC. Due to some restrictions, we weren't able to view your video. We'd like to know more information so we can provide a solution suitable to your concern. Can you provide the answers
to the questions below?

• What app are you using to convert the files?
• When did the issue start to happen?

In the meantime, if you're using an app to convert files, we suggest updating it as an initial troubleshooting step to resolve the issue.

 

The option converting m4a files to wma files in windows 10 is disappeared

• What app are you using to convert the files?

I don't use any app to convert the files. I just copy the m4a files from my music folder. Then I paste the m4a files in my android phone drive that connected to my laptop. Then a windows pop-up that shows the option converting m4a files to wma files appears.
You can see the windows pop-up in below picture. Now the windows pop-up is disappeared.

• When did the issue start to happen?

I found this problem last week. However, I didn't convert m4a files to wma files since May, 2017.

• Were there any changes made to your device prior to the issue?

I updated windows several times prior to the issue.

• Have you done any troubleshooting steps so far?

I haven't done any troubleshooting steps.

 

HEVC

I have tried playing some samples of 4k HEVC video files and my 2500K @ 4.5Ghz can not play it smoothly. Does anyone have any experience on getting HEVC to run more efficiently?


If not is there any way to use 2 PCs together and use each of their CPUs in tandem to play the files?
