Hey pikeman!!
Welcome to PCWorld Community!
OK , If you are to rid your system of Internet Explorer 8 beta 2 , and if you are in XP , then , you will have to
go to Add / Remove in Control Panel like cosatie said, and delete directly from there. If you are in XP then,
Internet Explorer 6 will come back up. IF you want Internet Explorer 7 back then you will have to download
from
Microsoft's internet 7 site .Click on the blue link.
If you are in Vista then, Internet Explorer 7 will reappear since this version is part of Vista and cannot be Uninstalled.
Now , for the Command Bar in Internet Explorer, just Right click on the same space as the Menu Bar ( Tools , Edit .Favorites....) and
simply Re-Enable the Command Bar.
BUT, if you are to rid yourself of this version of Internet Explorer , then, the next one that you download
and install will have the Command Bar enabled.
FLASHORN.

Patience is Life.
