I have researched this topic for about 5 hours now and tried every applicable fix (where indicated) but to no avail. After upgrading my customer's computer from Win 8.1 Pro to Win 10 Pro (via Windows Update) everything seems to be where it should and functioning properly except for the "Send To" Menu (which was working flawlessly in the previous version); when you right-click on a file and then left-click on "Send To" all that comes up is a small gray blank square where the "Send To" items should appear, even though they're all listed inside of the C:\Users\MyName\AppData\Roaming\Microsoft\Windows\SendTo folder exactly where they should be. I have deleted & recopied them in the folder as well as manually recreating them but nothing changes. I have verified that the registry entries relating to this are exactly as they should be with no corruption. I've re-registered all of the suggested dlls but no dice there either. I have scoured all of the available articles and verified that everything is correct and have run the System File Checker several times and it came up 100% okay each time. This must be some quirk brought about by the upgrade process because I've done about 6 clean Win 10 installs so far and I've yet to encounter this particular glitch.
I've noted that a lot of people have this identical problem but so far no one has come up with an answer, at least that I've been able to discover, so I hope someone has stumbled across one by now. It's obvious that I'm not the Lone Ranger here, for sure. Thanks & standing by...
