Use PInvoke and call MoveFileEx, passing null in as the destination....

This link has some sample code:

[DllImport("kernel32.dll", CharSet = CharSet.Unicode)]
public static extern bool MoveFileEx(string lpExistingFileName, string lpNewFileName, int dwFlags);

public const int MOVEFILE_DELAY_UNTIL_REBOOT = 0x4;

MoveFileEx(filename, null, MOVEFILE_DELAY_UNTIL_REBOOT);
