From the "Inventory and Asset Management" presentation at the 2011 Konference, I pulled this new information (that I can't find in the K1000 manual):

"Support was added for appending a 32 or 64 to the HKEY name as a clear way to know which hives is being used by the registry call. For example we can look for the status of automatic updates on each machine:
Native: RegistryValueReturn(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
\CurrentVersion\WindowsUpdate\Auto Update,AUOptions, TEXT)
32 bit: RegistryValueReturn(HKEY_LOCAL_MACHINE32\SOFTWARE\Microsoft
\Windows\CurrentVersion\WindowsUpdate\Auto Update,AUOptions, TEXT)
64 bit: RegistryValueReturn(HKEY_LOCAL_MACHINE64\SOFTWARE\Microsoft
\Windows\CurrentVersion\WindowsUpdate\Auto Update,AUOptions, TEXT)"

So I have some questions:

  1. Do these new terms, HKEY_LOCAL_MACHINE64 and HKEY_LOCAL_MACHINE32, work with the 5.1.38724 agent as well as the new 5.3 agents?
  2. The example shows HKEY_LOCAL_MACHINE64 and HKEY_LOCAL_MACHINE32 being used with the custom inventory field RegistryValueReturn function. Can they also be used in scripting? If so, logically they should work in the Verify section with all "Verify a registry..." steps, and in the other sections with all 5 of the "...registry..." steps. Is this true?
  3. In scripting, HKLM can be typed in place of HKEY_LOCAL_MACHINE, and the script editor expands it to the longer form. So can HKLM64 be used in place of HKEY_LOCAL_MACHINE64, and HKLM32 be used in place of HKEY_LOCAL_MACHINE32?
  4. Are other analogous registry keys supported, like HKEY_CURRENT_USER64 and HKEY_CURRENT_USER32? Any others?

Yes, I could learn all this by trial and error, but that would take quite a bit of time. I'm hoping one of the KACE gurus already knows the answers, and will share them! Sande


Hey, Dell KACE: Sure would like to see an answer to this! Other postings have also asked about HKLM64. How about we get all the answers in one place?

  • It's a year and a half later, and this _still_ is not documented, and I still don't know exactly where the 64 suffix can be used! Can anyone from KACE answer my 4 questions?

    And now I have another:
    5. Are the registry keys HKEY_USERS64 and HKEY_USERS32 also supported? (I hope they are, because we use these to modify Default User).

  • I have a question to add to this (has anyone answered your first 5?):

    6. If I want my custom inventory rule to collect information from 32 bit machines AND 64 bit machines (so I get a complete and accurate listing of, for example, last successful windows updates) is there a way to collect from both trees depending upon architecture?
    • You should be able to use the OR operator in a custom inventory rule to do both 32 and 64 bit. Otherwise you would need 2 rules. https://support.software.dell.com/k1000-systems-management-appliance/kb/118892
