How do I know if my registry key I have on hand is in 32-bit or 64-bit registry format? For example, I need this information to manually monitor the Windows registry with PRTG.
How do I discern 32-bit registry values vs. 64-bit registry values?

On 64-bit Windows systems, there are different registry editors available. Depending on the one you use to copy a registry key, it will be provided either in 32-bit or 64-format. The values are the same, but the key can be different between those two.
In the 64-bit version of the editor, all 32-bit values will be shown underneath the subkey
HKEY_LOCAL_MACHINE\Software\WOW6432NodeIn order to view the registry in the 32-bit editor, start it from here:
%systemroot%\syswow64\regeditMore
For detailed information, please see the following Microsoft article: How to View the System Registry By Using 64-Bit Versions of Windows
