No Task Bar

[Misty]

Probably nothing to worry about, but this morning when I logged on to my Windows desktop, everything appeared as normal,
except that on both my monitors there was no task bar showing. I moved the pointer down to the blank area where the
task bar should be and I got the egg-timer. Waited for a while, then closed down and restarted. Same thing happened again.
Only this time, I left the egg-timer going and when I came back minutes later things were operational.

Should I be concerned at all? Is it a foretaste of possible problems?

Dr Google is our friend:

If the Taskbar is not visible, power off the PC by clicking the Power button and then restart it by clicking the same button.
