Enable the Hide Add New Programs page Group Policy Object at User Configuration \ Administrative Templates \ Control Panel\ Add/Remove Programs.

When this policy is Enabled, it adds the NoAddPage Value Name, a REG_DWORD data type, at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Uninstall and sets the data value to 1. When the policy is Disabled or Not configured, the data value is set to 0 or the NoAddPage Value Name is deleted.
