Hi,
- Could you name these programs?
- Have you checked the status of these programs in the task manager?
Some programs are designed in a way that they do not appear in the taskbar if you minimize them instead they move to the system tray.
If you have seen those programs in the task bar before you may perform a clean boot and check if any third party application is causing a conflict.

Hope this helps.
