>If your profile is corrupt you could try a repair. Googling [windows 8.1 repair profile] brings up some ideas such as http://southpawprints.wordpress.com/2013/12/14/windows-8-1-corrupt-profile-the-good-bad-and-ugly/ , http://mywindows8.org/fix-corrupt-profile-in-windows-8/ .

BTW, when going at the page to create a new profile, it says to not copy the following files:

NtUser.dat
NtUser.ini
NtUser.log

In Windows 8.1, those files do not exist. It seems that relates to Windows 8 only. I would like to make sure I do the proper procedures before doing that.
