Windows 7 Tool / task bar change?

[kr236rk]

Hi,
My Windows 7 task bar below the desktop has reverted to the primitive square 'start' button as opposed to the newer round button. Why has this happened please? It looks like the task bar from Safe Mode? How can I get the proper Windows 7 bar back again please?
There were a couple of crashes yesterday, reason unknown. I did a boot scan and there are no viruses on the system. But I'm left with this 'basic version' tool bar. Perplexed.
Thanks.

• Right click on the desktop
• Select Personalize
• Select one of the Default Windows Themes it should revert your taskbar back to aero from your current classic.
