I have a suggestion for the SMSSLP parameter and registry key.
I was investigating the registry Key SMSSLP under HKEYLOCALMACHINE\SOFTWARE\Microsoft\CCM.
Most of my computers have a decommissioned Management Point in this Key. As far as I can tell this won’t have any effect. But this is confusing when troubleshooting client problems.
After some experiments these are my conclusions:
• The key is filled in when you use SMSMP=… as parameter for ccmsetup.exe.
• The key is read when you start ccmsetup.exe and then added to the command line as SMSSLP=…
• You can only change the key by adding SMSSLP=… yourself to the command line. (Or edit the registry of course.)
SMSSLP is no longer documented under https://docs.microsoft.com/en-us/sccm/core/clients/deploy/about-client-installation-properties
Maybe this information can be added to the documentation.
A better solution would be to get rid of the key completely, when it no longer has a function. Or change it when SMSMP is added as a parameter.
What is BR-Smhlp

Moving to client deployment, as this is product feedback. We explicitly removed SMSSLP parameter from documentation when SLP dropped. We don't recommend SMSSLP, it should be replaced by SMSMP.
