- Windows 10 Home users will automatically receive updates from Windows Update when they are available. Windows 10 Pro and Windows 10 Enterprise users will have the ability to postpone updates. The amount of time by which Windows 10 Pro users can postpone updates is limited.
- Small storage devices, like devices with 32 GB hard drives or older devices with full hard drives, may need additional storage to complete the upgrade. You'll see instructions telling you what to do during the upgrade. You may need either to remove unneeded files from your device or insert a USB flash drive to complete the upgrade.
- Some devices with either little free space available or smaller hard drives, like 32 GB storage PCs, may have little free space available after upgrading. You may free up disk space and easily delete files, like temporary files or your previous version of Windows, within the Storage system setting. Files for the previous version of Windows give you the option to remove Windows 10 and go back to your previous version of Windows. These files are automatically deleted 10 days after you upgrade. You can delete them now to free up space.
- An internet connection is required to perform the upgrade. Windows 10 is a large file – about 3 GB – and Internet access (ISP) fees might apply.
- To check for device compatibility and other important installation information, visit your device manufacturer’s website. Manufacturer contact information can be found on the Contact Information page.
- The upgradeability of a device includes factors beyond the system specification. This includes driver and firmware support, application compatibility and feature support, regardless of whether or not the device meets the minimum system specification for Windows 10.
- Support may vary by device. Find more information on the Windows Lifecycle page.
- If your PC or tablet is currently running Windows 7 SP1 or Windows 8.1 Update, you can check to see if it meets the requirements by using ‘Check my PC’ in the Get Windows 10 app. To open the Get Windows 10 app, click on the small Windows icon found at the right end of the taskbar. If you don’t see it, visit our Windows 10 Q&A page for more information.
- Many applications, files and settings will migrate as part of the upgrade. However, some applications or settings may not migrate.
- For anti-malware applications, Windows will check to see if your anti-malware subscription is current (not expired) and compatible during the upgrade.
- If the anti-malware application is compatible and current, your application will be preserved during the upgrade to Windows 10.
- If the anti-malware application is incompatible, Windows will uninstall your application while preserving your settings. After the upgrade is complete, if your anti-malware provider has informed Microsoft that it has made a compatible version available for your active subscription, Windows will notify you to install the latest available version with the settings that were set prior to upgrade.
- If your anti-malware subscription is not current (expired), Windows will uninstall your application and enable Windows Defender.
- Some applications that came from your OEM may be removed prior to upgrade.
- For certain third party applications, the "Get Windows 10" app will scan for application compatibility. If there is a known issue that will prevent the upgrade, you will be notified of the list of applications with known issues. You can choose to accept and the applications will be removed from the system prior to upgrade. Please make sure that you copy the list before you accept the removal of the application.
- The safety settings for Microsoft Family Safety child users with local accounts (accounts tied to the machine) will not be migrated to Windows 10 during the upgrade. This means that after the upgrade to Windows 10 is complete, parents would need to setup safety settings for the child user along with a Microsoft account if they do not have one. To find out more about the changes, visit the FAQ page.
