Disable Lync 2010 First Launch splash screen

(…And one more tweak)

I’ve been looking for a way to lighten up the end user’s first dip into Lync 2010 client.

I found two things annoying:

  • Address book takes a while to update.
  • The first Launch splash screen can make the users brake their screen.

The solution is a very simple registry fix. I edited the following registry jey with two options:

1. The first hive Shortens the address book pulling delay to zero – meaning the client will immediatley download the address book.

2. The second hive tells the computer that the splash screen has already ran, so there is no need to run it again (this registry key is being added during the installation of Lync client, and sets itself to the ‘0’ value after the first run. pre-populating the registry with this key means the first launch tour screen will not run).

You don’t have to use both keys, but I run them together to achieve a smooth, quieter client-side installation:
Windows Registry Editor Version 5.00



Make sure you deploy this registry key to your clients prior to installing Lync client.

  1. The GalDownloadInitialDelay registry key has nothing to do with the first play of the tour and is for the delay for download of the Address Book and should only ever be set on a client for troubleshooting.

    1. Hi Nobody,
      You’re right, the GalDownloadInitialDelay registry key has nothing to do with the first play of the tour. It’s stated in the post that it’s purpose is to speed up the download of the user’s address book.
      As for your comment regarding the setting of this key – it’s a known tweak widely used.
      Thanks for your comment 🙂

    1. Hi Paul.
      You can run this whenever you want, Even after installing Lync.

      If you have not signed in yet – you will not see the splash screen the first time you sign in and the contacts will download immediately.

      If you have already signed in for the first time – You already launched the splash screen, and it will not run again. If you wish to download the contacts immediately, you will have to delete the GalContacts.db and the GalContacts.db.idx files from this path:
      %userprofile%\AppData\Local\Microsoft\Communicator\sip_user@domain.com for it to work properly.


  2. Thanks for the great article, exactly what I needed for my conference room machines where different users log in all the time. I’ve added this to my login script so that it sets it for each user before Lync is ever even launched.
