Global Standard Products (GSP) are a subset of Dell’s relationship products that are managed for availability and
NOTE:
synchronized transitions on a worldwide basis. They ensure the same platform is available for purchase globally. This
allows customers to reduce the number of configurations managed on a worldwide basis, thereby reducing their costs.
They also enable companies to implement global IT standards by locking in specific product configurations worldwide.

Device Guard (DG) and Credential Guard (CG) are the new security features that only available on Windows 10 Enterprise today. Device
Guard is a combination of enterprise-related hardware and software security features. When you configure together, it locks a device and
it can only run trusted applications. Credential Guard uses virtualization-based security to isolate secrets (credentials) and only privileged
system software can access the system. Unauthorized access to these secrets can lead to credential theft attacks. Credential Guard
prevents these attacks by protecting NTLM password hashes and Kerberos Ticket Granting Tickets.
NOTE: Processor numbers are not a measure of performance. Processor availability subject to change and may vary by
region/country.

Commercial platform Windows 10 N-2 and 5-year operating system supportability:
All newly introduced 2019 and later commercial platforms (Latitude, OptiPlex, and Dell Precision) will qualify and ship with the most current
factory installed Semi-Annual Channel Windows 10 version (N) and qualify (but not ship) the previous two versions (N-1, N-2). The
OptiPlex 7780 All-in-One will RTS with Windows 10 version v19H2 at time of launch, and this version will determine the N-2 versions that
are initially qualified for this platform.
For future versions of Windows 10, Dell continues to test the commercial platform with coming Windows 10 releases during device
production and for five years post-production, including both fall and spring releases from Microsoft.
For additional information about N-2 and 5-year Windows operating system supportability, see the Dell Windows as a Service (WaaS), at
Dell support site.
