Application Launch Performance is Slower when Applications are Launched into an Isolation Environment

Symptoms

Application launch performance is slower when applications are launched into an isolation environment.

Cause

Launching isolated published applications requires more processing steps as compared to launching a native published application. These additional processing steps result in increased application launch time.

Published applications may take 60 seconds or longer to launch from an application isolation environment (AIE). The AIE component waits for the Windows Logon process, Userinit.exe, to complete processing before launching a published application. With this update, the AIE waits for the Userinit.exe process only when it needs to perform its registry shadow copy synchronization.

Applications may be slow to launch in an application isolation environment when the AIE incorrectly determines that the application is installed in the AIE install root.
