Before upgrading, please review this information and potential limitations/issues to consider:
In-place Upgrade vs. Clean Install
PCs can be upgraded to a new operating system in two different ways known as "In-place Upgrade" and "Clean Install".
During the In-place upgrade, your files, software and settings remain intact and will be available to you after you upgrade. This is the easier and faster method to upgrade and is the better option for most people.
The Clean Install deletes all the software, settings, and personal files on your PC. You will need to reinstall your applications and manually reinstall your personal files from backup. The Clean install will take longer than the In-place Upgrade.
Regardless of which method you choose, you should always back up your personal files and create HP recovery media before starting an upgrade.
Screen Resolution Requirements
To access the Windows 8 Store, download Windows 8 apps, and run apps in Windows 8, you need a screen resolution of at least 1024x768. To snap Windows 8 apps, you need a screen resolution of at least 1366 x 768.
Limitations with DVD playback software
If you currently have DVD playback software from Microsoft, this software will not run on Windows 8. To continue to play DVDs after you upgrade, you either need to acquire the Windows 8 Media Center Pack from Microsoft or purchase other DVD playback software.
Windows 8 Media Center Pack is available in the “Add features to Windows 8” section of the Settings menu
HP and Cyberlink are providing a special offer on Cyberlink PowerDVD to HP customers available at URL. See details at http://www.cyberlink.com/stat/oem/hp/win8_upgrade/enu/index.jsp
If you currently have DVD playback software from a vendor other than Microsoft, the Windows 8 installation process will help determine if it is compatible with Windows 8 or if an update is required for it to run on Windows 8. If the software is compatible and you conduct an In-place Upgrade you will have the option to keep this software during the upgrade. If you perform a Clean Install you will need to reinstall the software after the upgrade.
Limitations with Blu-ray playback software
If you already have third party Blu-ray media playback software, the Windows 8 installation process will help determine if this software is compatible with Windows 8 or if an update is required to run it on Windows 8.
If the software is compatible and you perform an In-place upgrade you will have the option to keep this software during the upgrade to Windows 8. If you perform a Clean Install you will need to reinstall it after the upgrade. If the Blu-ray playback software is not compatible, you will need to acquire third party playback software after the upgrade to play Blu-ray media. If you are using the Blu-ray software that was provided with your HP PC you can get a free upgrade from hp.com.
Limitations with TV Tuner software
If you currently have TV Tuner software from Microsoft, you will need to acquire Windows 8 Media Center Pack after you complete your upgrade. Alternatively, you can purchase third party software.
If you currently have TV Tuner software from a vendor other than Microsoft, the Windows 8 installation process will help determine if this software is compatible with Windows 8 or if an update is required for it to work on Windows 8. If the software is compatible and you conduct an In-place Upgrade, you will have the option to keep this software during the upgrade, however if you perform a Clean Install you will need to reinstall the software after the upgrade. Even if you install new software, recordings of TV made using Windows 7 may not be viewable once Windows 8 is installed.
Secure Boot & other UEFI dependent features
UEFI technology enables a number of improvements in PC security and performance and is implemented in all PCs pre-installed with Windows 8. Some PCs pre-installed with Windows 7contain UEFI technology and can be modified to deliver these features. However the process requires specialist skills to complete and at this time, HP is not providing instructions to perform this modification.
Limitations with touch screen capabilities
Windows 7 PCs with touch screens will not have full Windows 8 touch capabilities after upgrade.
HP PCs with touch input hardware designed for Windows 7 will provide a comparable experience for only two touch point applications after the upgrade to Windows 8. HP Windows y PCs with touch input hardware will not support Windows 8 applications that require more than two simultaneous touch points.
Additionally, Windows 8 edge swipes may not be available due to the recessed bezel on HP touch systems shipped with Windows 7.
HP TouchSmart Magic Canvas and HP TouchSmart applications are not compatible with Windows 8 and must be uninstalled before upgrading. Note that content created using the TouchSmart applications such as Graphitti will not be available after upgrading.
Do you use Microsoft Office Starter ?
Microsoft Office Starter is a limited functionality version of Microsoft Office 2010, providing ad-supported versions of Microsoft Word & Microsoft Excel. If you have not purchased a full version of Microsoft Office 2010, (Home & Student, Home & Business, or Professional), and are using Microsoft Office Starter, you must run Windows Update before you begin your upgrade. This will ensure that Microsoft Office Starter will continue to be available after you upgrade. If you do not run Windows Update, Microsoft Office Starter will not be available after the upgrade and cannot be restored.
If you choose to perform a Clean install, Microsoft Office Starter will not be retained and cannot be restored.
If you have purchased a full version of Microsoft Office, the software will be migrated in an In-place upgrade and can be reinstalled using the Product Key after a clean install
How to back up your personal files
HP strongly recommends that you back up your personal files (documents, photos, videos, songs) before performing an In-place or a Clean install upgrade. If you do not back up your files, you may lose them during the upgrade process.
If you perform a Clean install, you must first backup your personal files to avoid losing them and restore them after you upgrade.

How to create recovery media
HP strongly recommends that you create recovery media before beginning an upgrade. This will ensure that in the event of problems you can restore your current operating system.
If you do not have recovery media and your hard drive fails you may not be able to restore your original operating system after an upgrade.
