For example, pathnames that contain the system32 registry entry are written as SysWOW64 in the 32-bit section of the registry. Because of this, the 32-bit and 64-bit contents may differ. The WOW64 Registry reflector may modify the contents of keys and values during the reflection process to adjust path names, and so on. The reflector is intelligent, in that is only reflects COM activation data. To enable 64-bit/32-bit program interoperability through COM and other mechanisms, WOW64 uses a Registry Reflector that mirrors certain registry keys and values between the 64-bit and 32-bit registry views. This isolates HKEY_CLASSES_ROOT, because the per-computer portion of this tree resides within the HKEY_LOCAL_MACHINE\Software registry key. 32-bit programs see a 32-bit HKEY_LOCAL_MACHINE\Software tree ( HKEY_LOCAL_MACHINE\Software\WOW6432Node) that is completely separate from the true 64-bit HKEY_LOCAL_MACHINE\Software tree. To support the co-existence of 32-bit and 64-bit COM registration and program states, WOW64 presents 32-bit programs with an alternate view of the registry. For example, if the 64-bit version of Registry Editor is already running, type %systemroot%\syswow64\regedit -m in step 2 to start the 32-bit version of Registry Editor. You must close the 64-bit version of Registry Editor before you can open the 32-bit version (and vice versa) unless you start the second instance of Registry Editor with the -m switch. In the Open box, type %systemroot%\syswow64\regedit, and then click OK. To open the 32-bit version of Registry Editor, follow these steps:

There are no differences in the way you perform tasks between the 32-bit version of Registry Editor and the 64-bit version of Registry Editor. How do I know if my laptop can run 64-bit Click Start, type system in the search box, and then click System Information in the Programs list. You can also view or edit 32-bit keys and values by using the 32-bit version of Registry Editor in the %systemroot%\Syswow64 folder. To view or edit 64-bit keys, you must use the 64-bit version of Registry Editor (Regedit.exe). You can view or edit both 64-bit and 32-bit registry keys and values by using the default 64-bit version of Registry Editor. In the 64-bit version of Registry Editor, 32-bit keys are displayed under the HKEY_LOCAL_MACHINE\Software\WOW6432Node registry key.

There is no upgrade path from a 32bit to a 64bit OS.

But as others stated, you will need to back up your files and then install the 64bit OS. The WOW64 registry redirector presents 32-bit programs with different keys for 32-bit program registry entries. There is also a chance some of your RAM is being used by the onboard video adaptor, and thus moving to a 64bit OS wont give you that RAM back. The default 64-bit version of Registry Editor (Regedit.exe) that is included with 64-bit versions of Windows displays both 64-bit keys and 32-bit keys.

Many of the 32-bit keys have the same names as their 64-bit counterparts, and vice versa. The registry in 64-bit versions of Windows is divided into 32-bit and 64-bit keys.
