IDG News Service - Microsoft is investigating reports that some users are trying and failing to update their PCs and tablets to Windows 8.1, apparently due to outdated and incompatible drivers.
In messages posted to Microsoft's technical support website, users have been complaining that they're unable to complete the Windows 8.1 installation due to an error that the OS identifies as 0x40017.
The complaints started on Oct. 17, the day when the Windows 8.1 update became available for download on the Windows Store. Affected users see a message informing them that the Windows 8.1 installation couldn't be completed and that their previous version of Windows has been restored on their device.
