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.
