Footnote:
1.
Some product features may require advanced or additional hardware.
2. Downgrade Rights enable a customer who purchases a Windows 8.1 Pro license to utilize a different operating system in the place of the licensed OS. Specifically at Dell, we are enabling Windows 7 Professional in the place of Windows 8.1 Pro. The PC licensed for Windows 8.1 Pro may only have 1 Operating System installed at a time, so the customer may utilize a Windows 8.1 Pro Operating System or Windows 7 Professional. With this offering we are installing Windows 7 Professional in place of Windows 8.1, but providing the license to Windows 8.1 Pro in the BIOS so that when the customer chooses to upgrade to Windows 8.1, the customer will have a licensed and activated Operating System installed on the PC.
3. The EULA is the End User License Agreement. This is an agreement between the PC Owner and Windows
that enables the PC Owner’s right to use either Windows 7 Professional or Windows 8.1 Pro. For reference this document can be accessed from the following link: http://www.microsoft.com/en-us/legal/IntellectualProperty/UseTerms/Default.aspx (Instructions: Choose Pre-Installed on your computer from the computer manufacturer, Product Name: Windows, Version: 8.1 Pro, Language: your choice)
4. To enable downgrade to Windows 7 on this system the BIOS settings on this system were changed to boot into legacy BIOS mode. If the BIOS setting is not changed to native UEFI mode boot prior to installing, Windows 8.1 Pro [update] Product or Windows 8.1 Pro will install; however, the following Windows 8.1 Pro [update] Product, Windows 8.1 Pro functionalities will not work as they rely on a native UEFI mode boot:
• Secure Boot
• Seamless Boot experience
• Network unlock for Bitlocker for systems with a Trusted Platform Module (TPM)
• eDrive support
5. Feature requires access to network running Windows Server 2008 R2.
