The System Update Readiness Tool creates a log file that captures any issues that the tool found or fixed. The log file is located at the following location:
•%SYSTEMROOT%\Logs\CBS\CheckSUR.log
•%SYSTEMROOT%\Logs\CBS\CheckSUR.persist.log
The system root is normally C.
Please upload a copy of these logs to your OneDrive as shared files and post a link here.
If the System Update Readiness Tool fails to install please check to see whether either of the two logs are there and if they are upload them to your OneDrive.
You may need to change your settings in Windows to be able to see the file. To show hidden files type Folder Options in the search box above the Start button and select View, Advanced
Settings and verify that the box before "Show hidden files and folders" is checked and "Hide protected operating system files" is unchecked. You may need to scroll down to see the second item. You should also make certain that the box before "Hide extensions
for known file types" is not checked.
