• Make sure to back up your important files.

    caution:

  You should always back up all important data (such as personal files, photos, videos, documents, applications, software) before beginning to avoid any possibility of losing your data. See Backing Up Your Files (Windows 10, 8) for more information.

• HP provides installation instructions, compatible software, and updated drivers for most computers sold after August 2013.
• HP supports Windows 10 and Windows 8 in UEFI mode on all commercial and mobile workstation notebooks.
• HP recommends installing, and only provides drivers for, the 64-bit version of Windows 10 for personal workstation computers.
  • For the best Windows 10 experience, HP recommends that Windows 10 be installed to a GPT formatted disk for UEFI boot.
  • Personal Workstation computers with an MBR partitioned disk should perform a clean install of Windows 10. A clean installation (Keep Nothing) erases all files on the hard drive and removes any hard drive partitions before installing Windows 10. Clean installation instructions are provided later in this document.
• If you purchased your computer prior to August 2013, HP has not tested or developed drivers for your computer model. Some features might not work, or the installation might not be successful.
• With Windows 10 installed you automatically receive updates and security fixes from Microsoft. You cannot opt out of this service.
• Not all Windows 10 features are available on all computers, and your particular experience with Windows 10 is determined by the capabilities of your computer.
• Apps are sold separately.
• Software designed for Windows 8.1, or earlier operating systems, might not work after installing Windows 10.
• If you installed third-party software after purchasing your HP computer, you should verify that it is supported in Windows 10 by contacting the software vendor.

• You might not be able to view DVD movies after installing Windows 10. If you currently use a DVD codec to play DVD movies, such as the encoder that comes with Windows 7 Professional, this encoder might not be available in Windows 10. To continue to play DVDs after you install Windows 10, install a new media player app from the Windows Store (in English) or another trusted source.
• Windows Media Center does not work after installing Windows 10. It is removed during the installation and cannot be installed afterwards.
• For computers with available storage of 128 GB or less, the installation might require you to provide a USB hard drive (32 GB or larger). HP does not recommend using an SD card.
• SD card slots might not work after installing Windows 10. For this reason it is recommended to use only USB or microUSB external storage, not an SD card, as Windows 10 installation media.
• Microsoft includes a free voice recorder app in Windows 10 to record your interviews, classes, business meetings, and voice notes. This application might not work as expected on all machines. If recording functionality is missing on your device, check Windows Update for the latest driver.
• Face authentication requires specific hardware such as an infrared (IR) camera. If the computer does not have this hardware installed, the option to set up face authentication in the Settings app is not available.
• Fingerprint authentication can be set up in the Settings app for computers that have swipe or scan fingerprint readers. If the option to set up fingerprint reader in the Settings app is not available, you might need to upgrade the security software on your computer. In Windows 10, download and install the latest HP SimplePass or Digital Persona software. If you are using security software from another manufacturer, check with the manufacturer of that software.
• The Cortana personal assistant feature uses specific hardware such as a microphone, speakers, GPS and an Internet connection. The microphone in your computer might need to be configured to work with Cortana and results vary based on the specific microphone. Cortana might not be available in all countries/regions.
• In Windows 10, Wireless Display (Miracast) might not connect to an external display or might lose connection. Updated video and wireless drivers are required to enable the functionality. Check Windows Update for the latest drivers and install them when they are available.
• Microsoft Refresh and Reset might not correctly restore drivers and customizations specific to your HP system. You should only use HP Recovery Manager to restore the factory image, or Go Back to return to Windows 8.1. After Go Back expires, use HP Recovery Manager and re-install Windows 10 if a recovery is needed.
• Multi-finger Precision Touchpad, a new Windows 10 feature, provides high-precision pointer input and new gesture functionality. Your computer does not support the hardware requirement for Multi-finger Precision Touchpad. This feature requires specific hardware to function in Windows 10. In Windows 10 your touchpad will still work properly.
• Computers configured with Intel Broadwell (Intel Core i3-5xxx, Core i5-5xxx, Core i7-5xxx; Pentium 38xx, Celeron 37xx/32xx) or Haswell (Intel Core i3-4xxx, i5-4xxx, i7-4xxx; Pentium 35xx, Celeron 29xx) processors and 32-bit versions of Windows 8.1 are not capable of installing Windows 10 32-bit using the Windows Upgrade tool.

In some cases HP might not provide compatible software and updated drivers for your model.
