Windows Security warning

If you do an internet search for that message, there will be many results returned.

Either the certificate has expired, Windows needs updating, or disable the start-up page that TC is accessing.

Thanks for your nice notice. The license of our TC is permanent. And the windows keeps updating. Before some updating for windows, the dialog didn't pop out. Now I uninstall the updating and reset the browsers installed in my pc, but  the dialog still pops out.

It is not relating to your TestComplete licence.

Your Windows update may have caused this - I suggest you get your IT to look at this issue.
