Is it possible to File.Copy a file into a system folder? like System32?

I need to create files inside of a specific folder ("开发者_StackOverflowC:\Windows\System32\oobe\info\backgrounds") and possibly create said folder. When I try this with the File.Copy command windows won't grant the program permission, just throws an error. I am writing this in C# with VS2008.

EDIT: Windows 7, forgot about that part.

UAC. Have you added a manifest that requests elevated access? One of (don't ask me which...):

<requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />

or

<requestedExecutionLevel  level="highestAvailable" uiAccess="false" />

in the manifest file (app.manifest). The settings are discussed on MSDN.
