Returns a 64-bit registry object. This inspector is for 64-bit computers only; there is no 64-bit registry on a 32-bit computer. Note that "x64 registry" and "native registry" on 64-bit machines do NOT provide the same view as the 64-bit version of regedit (the "physical" view). If you try to access the physical location of the 32-bit view keys using a 64-bit view, it will be mapped back to the equivalent location in the 64-bit view.
On 2000/2003/XP/Vista, this inspector returns RegOpenCurrentUser. Under NT4, it uses HKEY_USERS\<sid>. On these systems, the inspector may fail if run in a non-privileged context. Under Windows 9x, it returns HKEY_USERS\<username> if it exists. Otherwise it uses HKEY_USERS\Default.
