Last night at my friend’s PC the error says “Couldn’t Update to Windows 8.1” during update of windows 8.1. Also I solve Windows 8.1 Installation Error 0×80070004 and Windows 8.1 Installation Error 0xc1900104 When Install Via USB Flash Drive. But here is another problem with error code 0xc1900101-0x20017. The error says “Couldn’t Update to Windows 8.1” and also tells Sorry, we couldn’t complete the update to Windows 8.1. We’ve restored your previous version of Windows to this PC. I think there are many things related to this issue like a system requirement, unknown software etc. Here I found some tips to solve this problem, so follow below tips and then update Windows 8.1.
