I did a clean install of Windows 8.1 Pro and I installed it using my Microsoft Hotmail account. My profile in the Microsoft Hotmail account was "Alfred H.W. Kaufmann". The Windows install program created a user folder called "AlfredH.W". Normally I could care less about that but when I use Microsoft Office and I want to insert a picture into a document, it looks for user folder "Alfred Kaufmann".

I would like to change the user name in my system to "Alfred Kaufmann" and if there is a way to do this, please let my know. I would like to make sure that 8.1, Office and Hotmail all have the same user name.
