I am getting old. I really like Visual Studio, but I am not a fan of the new all caps mode in the menu bar. If you want to stop yelling at you:
Open your registry editor and create the following registry key and value
HKEY\_CURRENT\_USER\\Software\\Microsoft\\VisualStudio\\11.0\\General\\SuppressUppercaseConversion
REG\_DWORD value: 1
Use at your own risk :).
Enjoy!
