How to prevent Skype for Business from automatically starting up for users who have moved to Teams

In our environment, we created a Group Policy with two items configured.

First, with the "Administrative Template files (ADMX/ADML) for Microsoft Office" installed (https://www.microsoft.com/en-us/download/details.aspx?id=49030), we configured:
User Configuration > Policies > Administrative Templates... > Skype for Business 2016 > Microsoft Lync Feature Policies
"Prevent users from running Microsoft Lync" - Enabled

Then, we added a registry setting under:
User Configuration > Preferences > Registry
New > Registry Item
Action: Delete
Hive: HKEY_CURRENT_USER
Key Path: Software\Microsoft\Windows\CurrentVersion\Run
Value name: Lync

By default, Skype will start automatically when Windows starts. You can change this setting.

Run Skype for Business.

1. Click the gear icon to open the Options dialog box. (If you click the arrow next to the gear, you will need to select Tools, then Options.) In the list on the left, click Personal.
2. On the right, under My account, you'll see a checkbox for Automatically start the app when I log on to Windows.
3. Check this to have the app start automatically.
4. Uncheck this to prevent the app from starting automatically.
5. Click OK.
