Frequently asked questions

Show all

The upgrade download product is supported in 140 countries, which are listed in the markets and other info section. If you live outside these countries, you can purchase the upgrade DVD to Windows 8.1 or Windows 8.1 Pro at your local participating retailer.

How many languages is the upgrade available in?

The upgrade is available in 37 languages, which are listed in the language list section.

What currencies are supported to purchase the download?

The download product supports purchasing in 23 currencies. Your location will determine which currency is available for purchase. You may need an international credit card to complete the transaction.

Will a debit card work for purchase?

Visa or MasterCard logo debit cards are accepted the same as credit cards (including AmEx, JCB, Discover and Diners Club branded debit cards in some regions).

Are the prices of the upgrade the same in every market?

Pricing varies by region and each independent reseller, and it depends on a variety of specific factors including exchange rate, local taxes, duties, fees, local market conditions, and other pricing considerations. The actual price you pay may be more than the advertised price, because of these additional factors.

What is the local pricing for the download in the 23 currencies?

The actual price varies by region because it depends on a variety of specific factors including exchange rate, local taxes, duties, fees, local market conditions, and other pricing considerations, and it might vary by each independent reseller. The actual price you pay might be different than the advertised price, because of these additional factors.

Is installation media available for purchase during the download?

Yes, you can purchase a backup disc of Windows 8.1 or Windows 8.1 Pro during the download process for an additional cost. The price is in addition to the cost of the downloadable software. You may also need to pay for applicable shipping fees, duties, and taxes for the DVD. Import duties and taxes may be assessed by the customs organization of the country that you're importing the media into. You should consult your local tax authority if you have any questions. You are responsible for any applicable duties and taxes.

Are Windows 7 touch-enabled PCs compatible with Windows 8.1?

If you have touch input hardware that isn't specifically designed for Windows 8.1, but is compliant with Windows 7 certification, you will experience touch responsiveness at least as good as it was on Windows 7. Because Windows 8.1 touch requires a higher degree of responsiveness and precision, Windows 8.1 certified touch PCs provide a much better experience typing on the on-screen keyboard and using certain controls than on Windows 7 certified PCs. For example, touchscreens that support fewer than five simultaneous touch points cannot enable certain Windows 8.1 features and applications.

Is Windows Media Center included in the upgrade to Windows 8.1 or Windows 8.1 Pro?

For customers moving from Windows 7, Windows Vista, or Windows XP (SP3) to Windows 8.1 or Windows 8.1 Pro, Windows Media Center is not included. If you want to install Windows Media Center, you need to install the Windows 8.1 Media Center Pack after you upgrade to Windows 8.1 Pro. For customers upgrading from Windows 8.1 to Windows 8.1 Pro using Pro Pack, Windows Media Center is included. For more info see our Add features page.

Will DVD playback work after upgrading?

If you don't have any other software that can play DVDs, then you'll need to download and install another app that can play DVDs after you upgrade.
If you currently have DVD playback software besides Windows Media Center installed on your PC, Upgrade Assistant helps determine if this software will work with Windows 8.1. If your PC is currently running Windows 7, you'll have the option to keep this software during the upgrade to Windows 8.1. Windows 8.1 and Windows 8.1 Pro are not designed for installation on devices running Windows Vista or Windows XP. Before installing, see windows.com/install for important information.

What is the minimum screen resolution for Windows 8.1?

To access the Windows Store and to download and run apps, you need a screen resolution of at least 1024 x 768. You also need this screen resolution to run the apps built in with Windows 8.1. To snap apps, you need a screen resolution of at least 1366 x 768.

Can all Windows 7 PCs be upgraded to Windows 8.1?

To upgrade a PC to Windows 8.1, the PC must meet the minimum system requirements for Windows 8.1 and pass required compatibility checks. For more information about Windows 8.1, including system requirements, see Install, upgrade, & activate.

Can PCs running Windows XP and Windows Vista be upgraded to Windows 8.1?
