It could be as simple as Windows caching the relevant parts of the Default User skeleton files in RAM. If you’re so inclined, try using up all the available guest RAM as the user before logoff, then see if the speed difference is still there. ---- Jack Kramer, Senior Consultant Small Type Computing - www.smalltype.net<http://www.smalltype.net> W: 855-765-8973 x101 - C: 248-635-4955

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!

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. ---- Jack Kramer, Senior Consultant Small Type Computing - www.smalltype.net<http://www.smalltype.net/> W: 855-765-8973 x101 - C: 248-635-4955 On Feb 6, 2018, at 9:50 AM, James Rankin <[email protected]<mailto:[email protected]>> wrote: 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? 😊 Cheers, <image001.png> <image006.jpg> <image007.jpg> James Rankin CTP ACA vExpert Technical Evangelist / Media Hound Howell Technology Group Office: 0191 4813446 Mobile: 07809668579 Email: [email protected]<mailto:[email protected]> www.htguk.com<http://www.htguk.com/> | Twitter<https://twitter.com/htguk> | Linkedin<https://www.linkedin.com/in/megan-holland-368bb0150/> | Facebook<https://www.facebook.com/HTGUK> COMPANY INFORMATION Howell Technology Group Ltd is a limited company registered in England with registered number 5520670 and VAT registered number GB862 6660 04.
