Windows 10: I boot up my pc and my desktop and task bar are blank

I tried to make myself the administrator of my pc a few days ago by changing permissions on the registry keys, I restarted the system and when it boots some desktop icons are missing and my taskbar is completely white and blank, I click on anything in the desktop and it tells me access deniedThis happens no matter how many times I restart

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.

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.
