Windows 10: What is this LOCK icon in my system tray

I noticed this icon in my system tray a few weeks back but if I place my mouse cursor on it or double click it it automatically disappears (please refer to the screenshot the lock icon outlined by black marker)





Can anyone please help me identify what it is.

I am using Windows 10 Pro Version 1809 (OS Build 17763.577)

Thanks.

I suggest you to try the below steps to add the icons to Taskbar and check if it helps.

System Tray Icons Don't Stay in Tray and Instead Keep Moving Up Into "Off Icons"

I tried this suggestion to keep the tray icons I want in my tray THERE

instead of moving up into the icons box at the system tray arrow.

I tried these instructions listed on this site in answer to the same question:

1. click Start.

2. Type Customize icons.

3. click Customize icons on the task bar.

4. Click Turn system icons on or off.

5. Set the icons that you want to On.

6. Click ok.

That works, but not for long.

Then the problem repeats.

I'd like a solution that keeps the icons I select IN THE TRAY till I change them,

even if I power on or off.

The solution seems like it should be simple, but it's not.

To save you time helping me:

I've researched the other threads, and I will not change the Registry,

or create a new account, or do another
System File Checker (SFC),

or try the solutions listed in those other threads that did not result in a solution,

so please do not propose those.

Do you have an idea that might work? Would love to hear.

Windows 10, updated.
