Hey guys, I've encountered a computer that can't open any media as TWINUI is set as the default app for music, images, and videos. The files can be opened when pressing right click - Open With - VLC Player or Picasa 3 or AIMP3, but when I want to set those programs as the default apps, it's a futile attempt as it closes and TWINUI is still set as the default app.

I've tried to clean the computer with Malwarebytes, Adw Cleaner, and Spy Bot, but I don't think the computer recognizes it as a virus. So it might be useless. Do you guys have any way to eliminate TWINUI? I really don't want to reset this PC as I don't know for certain that it will fix it and it will take for ever.

Thanks for your help guys.
xCinis.

Try this... Go to Settings / System / Default Apps select from the bottom Set defaults by app than select VLC from the list and click on Set this program as default. This will set VLC to be the default for all files it will open. Do the same for Picassa and AIMP3. Do the same with other programs that you want to set as the default app for the file types it will open. Eg. Adobe PDF Reader for PDF files...

TWINUI is not a virus, it is rather known as the Tablet Windows User Interface. If this program is set as your default program, it is often caused by registry corruption. If TWINUI then recognizes it, it will become the default program.
