Odd Desktop Icon Changes

My screen occasionally has some very odd modifications to the desktop icons. They never last and don't really bother me, I took a screenshot of the latest, any idea what is going on? Just curious.

 

Do you have any tweaking program installed that would modify the shell icon overlay?
To fix the overlay, right click the start button and select Windows Powershell (Admin)
Copy/paste the following command and press Enter:

REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Icons" /f /v 29

Restart the computer for the change to take effect.

 

Like I said, not aggravating just puzzling. When I copied the folder in preparatio for my weekly backups I got this. As far as I know stock Win10. though I do have a search program called Agent Rensack installed.

 

I have a similar issue on a WinXP laptop at my mother's house. Two icons on its desktop point to two drives that are sometimes connected via a USB port. When not connected, the icon indicates with a question-mark that it doesn't know what drive it is. It has only one working USB port, so I can only connect one drive at a time. It's okay, because it honestly doesn't know what type of drive it is until I connect it. Just commenting....

 

Ever thought of a powered USB Hub? It both protects the computer (I have zapped my motherboard USB overloading it with a apple device) and allows several more USB devices to be connected to her computer. It shows up when I am doing something with the folder such as copying it to a backup drive, something I do weekly.

 

That did work, thanks.

 

Still wondering why Win 10 did it.
