How to disable the automatic launch Citrix Workspace App for Windows when logging into the OS

Instructions

Option 1. (Through Task Manager. this is easiest option)

Open Task Manager > startup tab 

Right click "Citrix Connection Center"  or short name "concentr" and click Disable

Right click "Citrix Workspace" or short name "SelfServicePlugin" and click Disable

* If Store URL hasn't been added on CWA, there is no Citrix Workspace on the startup tab in Task Manager.

Option 2. (Through Registry. if you need to disable startup settings by script, you can use this option.)

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Run         

 In the right pane, look for entries related to Citrix Workspace App: ConnectionCenter and Redirector and Delete the Entries

 [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\StartupFolder]

Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
