Till xa 6.5, we had direct option to remove services site shortcuts for citrix apps. From xd 7.X, we have to use command line to do the same. So, use a script like this:

if “%PROCESSOR_ARCHITECTURE%"==“AMD64” goto 64BIT

echo 32-bit OS

start "” /wait “C:\Program Files\Citrix\ICA Client\SelfServicePlugin\SelfService.exe” -logoff

goto END

:64BIT

echo 64-bit OS

start "" /wait “C:\Program Files (x86)\Citrix\ICA Client\SelfServicePlugin\SelfService.exe” -logoff

:END

Create a logoff policy via gpo or copy above script bat file to logoff folder in user’s machine. Complete list of commands are given here: [https://support.citrix.com/article/CTX200337

(https://support.citrix.com/article/CTX200337) You can also give it a try with registry key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Dazzle] or [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle] “ClearAppListOnExit”=“True” “ClearAppListOnLogoff”=“True” “DontWarnOfRemovedResources”=“True” “RemoveAppsOnExit”=“True” “RemoveAppsOnLogoff”=“True”
