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.
