Icons/files don't delete properly

[Phototaker]

I usually save new files onto the desktop before moving them or deleting them when they are no longer required.

But what I'm finding it that I can right click on say a jpeg image & select delete but the thumbnail still appears on the desktop.  If I click on it again Windows 10 tells me that I can't find the file to delete.  I have all of Microsoft updates  installed on Pro 64 bit version.

If I reboot the machine I will find that the thumbnail are finally gone.  I also have Classic Shell installed.  Could this be an incorrect setting?

Is this something that I can fix?

Go into task manager and select explorer right click and choose restart. Sometimes explorer.exe hangs this may be a temp fix for you let me know ill try to investigate this further.

I found, need to rebuild the icon database; search FIXWIN, it does it automatically
