Hi,
This may not fully solve the problem, but it may be worth trying the following method.
Press Windows logo key / Ctrl+Esc to see if the Start menu appears. When the Start menu appears, the taskbar might appear as well. If the Start menu appears, but the taskbar doesn't, try pointing your mouse to the area where the taskbar would be, and see
if it then appears after that. If this doesn't work, try using Alt+Tab to switch windows. When a new window is selected, the taskbar might appear. If this doesn't work, try using Windows Flip 3-D (press Windows logo key+Tab) to switch windows (you must have
a computer that supports Windows Aero, though), and see if it then appears after that.
If the Start menu didn't appear at all after pressing Windows logo key / Ctrl+Esc, it might be worth browsing through Help and Support (press Windows logo key+F1 to open) to see if there is anything useful there.
I hope this helps, and good luck.
If this doesn't work and / or if this isn't useful, just reply to this, and I'll see if I can get back on the issue to offer more useful advice.
