When you open the context mennu from the DO icon on the taskbar it shows a number behind DO and I don't think it's ever been anything but a (3). What does the 3 mean?
Maybe the number of currently open windows? Not sure. It's put there by Windows, not us.
FYI I don't see any orther open or non-open programs that even have a number at all.
I don't see a number in Win 10 Opus 13.11.1.
It's just link's filename. If you somehow pinned it multiple times to taskbar, that number goes up. You can try to rename it, if you right click on "Directory Opus (3)".
It shows on my desktop but not on my laptop.
You got it. %APPDATA%\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar had the link listed 3 times but unpinning it didn't work. I had to delete all the pins from the directory and then it takes some time to rebuffer I'm guessing. I was now able to pin it to the taskbar without getting that (3).
Thanks
