How to make taskbar horizontal

My taskbar is on the right side of the screen in a vertical line..how do I get the entire taskbar to go back to the bottom of the screen in a horizontal line? My task bar is unlocked..but I cannot get it to go horizontal....I've had this happen before and was directed to a list of shortcuts that you could click on and it would fix the problem...I cannot seem to find that info.....any help on this matter would be greatly appreciated.

That does not work at all for me...all that does is make it a bit wider, it does not make it go back to its original horizontal location across the bottom of the screen. I hope someone can tell me how to get my taskbar back to default.....?????? .......THANKS AFORD10, ALTHOUGH IT STILL DIDN'T WORK FOR ME, I WAS ABLE TO FIND THE SHORTCUT PROGRAM TO GET IT DONE...THANKS VERY MUCH FOR RESPONDING TO MY THREAD-I DO APPRECIATE THAT.

OK I DID SOME MORE DIGGING AND IN THE FORUM "TASKBAR LOCATION" I FOUND MY ANSWER...I HOPE THIS WILL HELP ANYONE ELSE THAT HAS THIS PROBLEM
