If your Windows 11/10 Upgrade has failed and if you have noted down the error code, then this post offers some basic solutions to troubleshoot & resolve the problem. We have seen how to troubleshoot Windows Installation & Update Failed Errors. In this post, I will list down the Upgrade error codes and their resolution process, which has been sourced from Microsoft.

How to identify what the error code stands for:

Let’s say the error code is 0x80070070

“8” indicates that this is a Win32 error code
The last four digits are 0070, so look up 0x00000070 in the Win32 error code table on MSDN.
The error is: ERROR_DISK_FULL

Let’s say the error code is 0xC1900107

“C” indicates that this is an NTSTATUS error code.
The last four digits are 0107, so look up 0x00000107 in the NTSTATUS value table on MSDN.
The error is: STATUS_SOME_NOT_MAPPED

Some result codes are self-explanatory, whereas others are generic and require analysis.
