Click on Start, Run, type "regedit" (without the quotes), then click on OK.
IF YOU HAVE NEVER DONE THIS BEFORE, BE CAREFUL. You can delete other start up programs by following this path to the Registry. First, make a backup of the Registry. Click on Start-Run. When the box opens type in "Regedit" (without the quotes). Click Ok. When the Registry Editor window opens, Click on Registry in the upper left corner of the window, choose "Export Registry File". When the next window opens, be sure of the location where you are saving it to and give the file a name like Backup. Click "Save". You now have a backup registry that can be double clicked and will replace the new one you?re going to make, IF you make any deletions you don't like.
Separately, navigate to the locations below:
HKEY_CURRENT_USER\Software\Microsoft\InternetExplorer\Toolbar\Explorer
HKEY_CURRENT_USER\Software\Microsoft\InternetExplorer\Toolbar\Shellbrowser
In the right window pane of each path above, highlight the key: ITBarLayout, RIGHT click on each of the keys, choose "Delete". Click on the X in the upper right corner of the Registry Editor to exit and save the changes. Restart the computer and new "default" entries will be created when needed.
Open My Computer and see if the Menu Bar is back correctly. If it is not, double click on the registry file saved to the desktop to re enter the value in the registry since removing it didn't resolve the issue.
Hope this helps.
