In version 17 of Parallels RAS, we've added a Session Pre-Launch option.

Usually, when a user opens a remote application, a Windows session must first be launched. Launching a Windows session can take some time, which will result in the user waiting for the application to start. Session Pre-Launch improves the user experience by launching a session ahead of time, before the user actually opens an application.

You can enable the option either from Parallels Client, or from RAS Policies in the Parallels RAS Console.

It can be enabled either in Basic or Machine Learning modes:

• Basic: A session is pre-launched as soon as the user gets the application listing. The assumption is that the user will open an application within the next few minutes. The session will stay active for 10 minutes. If the user doesn't open an application during that time, the client will disconnect from the session.
• Machine Learning: When the application listing is acquired, a session is pre-launched based on user habits. With this option enabled, Parallels Client will record and analyze the user habits of launching applications on a given day of the week. A session is started a few minutes before the user usually opens an application.

​​

When a session is pre-launched, it will all happen in the background, so the user will not see any windows or message boxes on the screen. When the user starts an application, it will open as usual in its own window.

Exclude sessions pre-launch allows you to specify dates on which the pre-launch must not be used. Click on the plus-sign icon and select a date. The list can contain multiple entries.
