Taskbar - Left/Right corners not working


Markus Rinkenburger

Question

Hello,

 

since 2 weeks we have some taskbar problems on Server 2016 with XenApp 7.15 CU4. Somethimes a few users can't left mouse click on objects in left and right taskbar corner. Right click is working fine. Also left click is working in the middle of the taskbar for currently opened applications. After logoff or just waiting a hour it's often working again.

Any suggestion why this is happening? We also use citrix profile management.

Looks like the problem is, that the ShellExperienceHost.exe is not started. Can't find any reason why this is happening.

Must be a problem with Citrix UPM, because i don't have any problems with admin account and logging in with local accounts.

 

Here are my exclusions for citrix UPM:

After days of research i found some registry keys with hundred thousand of registry values that are possibly responsible for my start menu problem. Browsing the registry here takes 15 minutes or longer to open the keys.

 

The keys are:
"HKLM:\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\RestrictedServices\Configurable\System"

"HKLM:\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\FirewallRules"

"HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Notifications"

 

Is it possible to delete/clean this keys or do i get any other problems after deleting them?

Maybe there is another possible fix?
