Task Bar Takes forever to load

[Super6VCA]

Been fighting login times with horizon (in my environment) for years with not much luck.  However, I am getting a little closer in the past few weeks.  The issue now is that I get my desktop in about 60 seconds but m taskbar will not show up for another 60 seconds.  Tried looking at different windows settings with no luck and it's getting pretty frustrating.  My guess is that it's something in the Optimization tool but not sure.  Anyone else have taskbar issues?  Any help or comments are welcome.  Thanks

One thing we have always done from the beginning of the Windows 10 days is to go in on the base images and delete the Stubpath keys from the registry locations below. Originally, I want to say this helped with things like what you are seeing as well (honestly been 8+ years or so since we originally found this so can't 100% remember the exact reason) as cut login time down some.

Windows 10:

Delete all StubPath keys from HKLM\Software\Microsoft\Active Setup\Installed Components and HKLM\Software\wow6432node\Microsoft\Active Setup\Installed Components

We are still testing Windows 11 for doing the same and if it helps or not.

Gave that one a shot and didn't do much for me.  Appreciate the idea though.

Run this script from ControlUp that will show timings for various sections of the logon. It needs one parameter which is the domain\username of the user to analyse - run it in elevated PowerShell where the user is logged on.

Hello, if you disable 'Profile' under 'system' optimizations in the OSOT tool, you might feel that taskbar loads faster but it will keep one of the windows 'loading' screen while it works in loading the taskbar in the background. 

Additionally, check this KB article.  https://kb.omnissa.com/s/article/94532

there's a lot of additional context needed here, otherwise anything's going to be a stab in the dark...

• what os/version are you using for your image?
• what are you using for your profile solution?
• are you using AppVolumes (what version)?
• are you using FSLogix (what version/which container)?
• are you applying any significant gpos (aka how long does it take a physical desktop to login in this same environment)?

Did you run the ControlUp script I suggested? It is used a lot for troubleshooting slow logons.

We have seen the same issue. In OSOT we deselected the option under SYSTEM\Profile\ Shorten Timeout of Desktop session switch.

Taskbar is now very fast, however the delay we had on the taskbar is now moved to Preparing Windows. So problem is not solved but is moved earlier in the logon process.

This is a very similar problem to the "Blank Screen" issue caused by Cortex XDR and Sophos Intercept-X MDR.

The shorten desktop switch and removing profile optimization eliminates the blank screen, but leads to an extended "Preparing Windows" screen.

Did you run the ControlUp Script @Super6VCA? You don't need to be a ControlUp customer or user to run it - it's free! It's frequently used in EUC for logon troubleshooting
