How to disable all caps menu titles in Visual Studio

Richard Banks posted about a registry key for just such a tweak.

Visual Studio 2012 (Full)

HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0\General
DWORD: SuppressUppercaseConversion
Value: 1

In PowerShell, you can run this to set that registry key and the uppercase goes away.

Set-ItemProperty -Path HKCU:\Software\Microsoft\VisualStudio\11.0\General -Name SuppressUppercaseConversion -Type DWord -Value 1

Visual Studio Express 2012

The above registry key is not the one that will affect Visual Studio Express 2012 RC. A comment by FormatC showed up on Banks post about the key for Express. You can find that key mentioned in Mike Gleason's answer or run the following PowerShell command to set it.

Set-ItemProperty -Path HKCU:\Software\Microsoft\VSWinExpress\11.0\General -Name SuppressUppercaseConversion -Type DWord -Value 1

Visual Studio Express 2012 for Web

Set-ItemProperty -Path HKCU:\Software\Microsoft\VWDExpress\11.0\General -Name SuppressUppercaseConversion -Type DWord -Value 1

Visual Studio 2013

Replace 11.0 with 12.0 in the registry keys above.

Visual Studio 2015 Developer Preview

Replace 11.0 with 14.0 in the registry keys above.

After years Microsoft has changed their mind on this feature. As of Visual Studio 2013 Update 3 RC, an option has been added to change between mixed case and upper case: Tools -> Options -> Environment -> General -> Turn off upper case in the menu bar
Obviously this is not for VS 2012 but going forward this option will be there.

Here is the notification from Brian Harry of Microsoft:

Mixed Case Menus – I know I’m going to get some feedback on this one :) This is a long standing request by a vocal portion of the VS user base since VS 2012 to change the “ALL CAPS” menus. In VS 2013 Update 3, we have added a Tools –> Options setting to control whether you see ALL CAPS or Mixed Case. The default is still ALL CAPS but, if you change it, it will persist across upgrades and will roam across your IDE instances using the VS Online roaming settings feature (if you log into VS so it knows who you are).

I have written an extension which will do this for you.

You can download it from the Visual Studio Gallery:

• VSCommands for Visual Studio 2012
• VSCommands for Visual Studio 2013

It can also hide main menu altogether and have it appear only on mouse over or alt key press (like in IE)
