Pre-Launch issue

[hakki007]

I have created a application pool with Customer application, Word, Edge and Teams with Pre-Launch enabled. All part of different windows 10 image

Each applications takes roughly about 50+ seconds to open on the screen.

Is there anything that I can do to optimize and reduce the time it takes to open

Login performance issues take some drill down to identify the source(s). 

Typical Sources

• Stale GPO - Legacy GPO pointing to old UNC paths, consume significant login time until they give up trying. 
• Printer GPO - Both deprecated and active Printer GPOs can add significant login time as well depending on various factors. 
• Profile Management - New profiles being created on login instead of leveraging profile management suites or mandatory profiles. 

As you can see, quite a lot can affect those login times. Its best to review the system, application, printer, and GPO event logs to determine where the bottleneck(s) are.
