Hello TechQ,
Thank you for posting in our Q&A forum.
Based on the description, I understand you assign a software deployment to AD user via "software installation" policy under "User Configuration".
You want only one person to install software. Please try the setting below:
1.Keep the Authenticated Users, and uncheck the "Apply group policy" permission for Authenticated Users.
2.Add this AD user and make this user have "read" and "Apply group policy" permissions.
Hope the information above is helpful.
Best Regards,
Daisy Zhou
