Manifest file changes some GUI appearance on Windows
The inclusion of a manifest file (such as abt.exe.manifest) defers decisions about some GUI appearance elements to Windows. Specifically, shortcut keys are underlined without a manifest, but with a manifest, the underlining is controlled in the operating system, and the default is not to underline shortcut keys.
To change the default underlining of shortcut keys on Windows XP:P
•open the control panel;
•choose “Display”
•select the Appearance tab;
•click the Effects button;
•the resulting dialog has a check box for "hide underlined letters for keyboard navigation until I press the Alt key"; it should not be checked;
•dismiss the dialogs with OK.
To change the default underlining of shortcut keys on Windows Vista or Windows 7:
•open the control panel;
•choose "Ease of Access Center";
•choose "Make the keyboard easier to use";
•scroll down to "Underline keyboard shortcuts and access keys" and check it;
•click Save.
