Windows 10: Icon for newly-installed app appears as blank in the task bar

I just downloaded and installed an app. It appears in my Win 10 taskbar as a blank icon, despite the fact that in File Explorer the icon appears correctly against the .exe I can run the app OK if I select this blank icon, but it's annoying not having the correct icon showing. What can I do?

task bar icons blank

After applying the november windows 10 home update three of my task bar icons have become blank sheets. The ones changed are edge, store and wunderlist. The remainder are fine. The icons of the three appear correct in the all apps list. I have tried
unpin and re-pin with no change. The three applications work correctly and start fine from the task bar. It is just hard to remember which application is which blank. Note this has happened on my hp laptop which was upgraded from windows 8.1, My desktop
which has windows 10 professional does not have the problem. It was upgraded from windows 7 professional.

Any suggestions would be appreciated.

 

Newly Pinned Icon On Taskbar Appears As A Blank Page Icon

Hi,

It is possible that you have not pinned the correct executable file. To properly isolate your issue with pinned icon on the task bar, kindly verify the following queries below:

• Did you receive an error message when clicking the blank page icon?
• Have you tried deleting the pinned icon from the taskbar and try to pin the icon again?
• Have you tried opening the file location of the app and pin it again on the task bar?
  

We're looking forward to your response.

 

task bar icons blank

Thank you for the suggestion. I checked a different user account which I had setup when windows 10 was first updated but had never accessed since. It does not have blank task bar icons.
