If you happen to be giving Visual Studio 2012 RC a run around the block and noticed all of the menus are in CAPS, you can drop this in a Setting.reg file and import it…

[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\General]
"SuppressUppercaseConversion"=dword:00000001

If you decided that you want to go back, change the contents of the file to the following and import it again…

[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\General]
"SuppressUppercaseConversion"=-

Update (10/13/2014):

These same instructions can be applied to Visual Studio 2013 as well by substituting the ‘11.0’ value for ‘12.0’. For those of you using Visual Studio Express 2013 for Web, the same instructions while substituting the ‘VisualStudio’ value for ‘WDExpress’ will work.

With whatever version you are using, if you don’t want to open the Registry Editor, you can also enable it using PowerShell and the appropriate registry string like so…

Set-ItemProperty -Path HKCU:\Software\Microsoft\VisualStudio\12.0\General -Name SuppressUppercaseConversion -Type DWord -Value 1
