Microsoft is committed to having everyone use the Start screen instead of the Start button and start menu found in previous versions of Windows and therefore has no setting to enable or disable the start button in windows 8.
But in windows 8.1 Microsoft brought the start button back even though it isn't the Start button of old. The classic multi-step application launcher is still missing.But you may be able to use third party software like Start8 to bring back the old Start button experience in windows 8.1 once it is released.
Either your friend is using Windows 8.1 preview or she installed a third party software.Third party software like Start8 can be used for start button in windows 8.The article here gives 6 start menu replacements for windows 8.
3If your friend is running Windows 8.0 then third-party software is being used. There is already a question that outlines about 12 different choices. If you are running Windows 8.1 then third-party software is not required for the button but is required for the
Start Menu
. Most of those same choices will be updated to support Windows 8.1 – Ramhound – 2013-09-24T11:20:46.590http://superuser.com/questions/490192/start-button-for-windows-8 – BlueBerry - Vignesh4303 – 2013-09-24T11:26:29.410
haven't used it but apparently 8.0 has no button and 8.1 does. so maybe she has 8.1 that's how she got it without third party software. – barlop – 2013-09-24T11:29:13.007
@Ramhound post that as an answer so it can be accepted and this question marked as answered. – xdumaine – 2013-09-24T12:07:45.553
@xdumaine - I am not going to duplicate an answer that already exists. if anything the question that already exists should be updated to explain the changes that happen with Windows 8.1 – Ramhound – 2013-09-24T12:11:14.667
@Ramhound Unfortunately that rarely happens. Technologies get updated, and people post new questions. – xdumaine – 2013-09-24T12:23:31.803
@xdumaine - Feel free to post the answer yourself. I would rather post a new answer to a new question then a duplicated ansewr to an already existing question. – Ramhound – 2013-09-24T12:30:24.093
The Start Button does NOT equal the Start Menu/Screen. This is not a dupe IMO, as the OP is specifically asking about the Start Button on the desktop. – Ƭᴇcʜιᴇ007 – 2013-09-26T14:59:33.877
