User(s) can reproduce this bug

SerializerProvider serializerProvider = new SerializerProvider();
throws a System.UnauthorizedAccessException, trying to access registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WinFX Serializers

I consider this a bug, since a user mode app should be able to use Xps serializers without any rights elevation.
After googling some about this problem I found a few other reports. It seems to be related to windows 7 x64.
When using regedit as administrator, I cannot find that key in windows 7 registry neither in normal location nor in the 64bit mapping path.

Details (expand)

Visual Studio 2012

1. Create a normal WPF desktop application.
2. Add a wpf button to the start parge.
3. Add a Click- handler.
4. In C# code behind file add using statement for:
System.Windows.Documents.Serialization
5. In c# handler type:
SerializerProvider serializerProvider = new SerializerProvider();

6. Run and press button.
-> You see the exception on a win7 x64 machine under a standard user account.

Note: I use Microsoft Visual Studio Express 2012 for Windows Desktop.
Version 11.0.51106.01 Update 1
Microsoft .NET Framework
Version 4.5.50709

If the application is started with administrator-rights (Run as Administrator), the exception does not occur.
