Horizon 7.2
Profiles are discarded by setting the HKLM\Software\Microsoft\Windows
NT\CurrentVersion\ProfileList\{SID}\State value to 128 at logoff, which means
the OS thinks that it is a temporary profile and purges it. So nothing from
C:\Users or HKCU is retained at all. Yet still – next logon is half the time.
We’re not using Persona Management of any sort, and I’ve removed all logon
scripts
The testing I am doing isn’t doing a refresh or recompose on reboot, which is
why I’m getting really confused. I thought about Superfetch, which has been
disabled by the VMware OSOT, but re-enabling that didn’t do anything.
Well confused!

Subject: Re: [NTSysADM] Hmmm....
What version of Horizon are you running? You say profiles are discarded—are you
redirecting profiles to disposable disks or retaining them on the C: drive? Do
you have the registry keys set to discard profiles as well as the Horizon
settings for it? (The ones I can think of offhand: removing local/roaming
profiles at logoff under the normal Windows administrative templates; the
Horizon Persona Management ADM/ADMX template settings; the Horizon disposable
disk settings)
If you’re just using redirection to disposable disks and not also discarding
the profiles the other ways I would expect there’s some data being kept in HKLM
that wouldn’t need to be recreated at every subsequent login. HKCU would be
thrown away with the disposable disk (since it’s the user hive) but anything in
HKLM would be retained until the refresh operation occurs on reboot. Also, if
you’re perhaps triggering a login script that licenses some software on a
per-user basis, etc.

Ok, so can anyone shed any light on this….
I have a VMware VDI implementation running Windows 7. The user profiles are
discarded at logoff, so no user profile information is retained at all on the
machines. When a user logs off, the machine is restarted. This keeps all
machines in the pool in a pristine state (as the client wants).
However, when a user logs on for the first time, the logon takes 20 seconds. If
I remove the machine from the pool (so it doesn’t get restarted at logoff), and
log the same user in again (bear in mind the profile is discarded at logoff),
the logon takes 10 seconds. Each subsequent logon for the user will be solidly
10 seconds, unless I restart the machine, and then we are back to 20 seconds
for the first logon.
It doesn’t matter if I log a *different* user in before logging in the test
user – each user experiences their first logon to the machine as 20 seconds,
and all subsequent tries as 10. Each user has their profile discarded at
logoff. It’s almost as if some process is running at first logon that then
stores some user-specific information or data outside of the user profile but
in a user-specific location – yet I can’t for the life of me speculate as to
what it might be.
Any ideas anyone? 😊
