Why TestComplete cannot detect objects n windows security popup (to enter credentials ) in windows10

We are trying to automate a application that requires us to firstly enter our credentials in windows security popup (enter credentials) to connect to the application.

Our client PC is on Windows 10

In our previous executions on windows7 OS, this was not a problem as TestComplete Object spy could detect the objects (username, Password, Remember me Checkbox) inside the windows securrity popup and get/set the values/inputs.

Note the popup form of  Windows security popup is changed in Windows 10, and its unlike Windows7

Our TestComplete Object spy cannot go inside the popup, its stops at the perimeter of the popup (see screenshots)
We tried many approaches to get aside this issue, but we are totally blocked on Windows10.

We need to have this feature operational on windows 10 as its on Windows 7,

Need HELP!

Our TC version is 12.42
We have both Web and Desktop licenses for tests.
