SQL Server error code 1060 happens when a table already contains a column with the same name being added. It prevents creating or altering the table with duplicate column names. To resolve, check the table schema, remove or rename the duplicate column, and retry the operation.
I found the command dism /online /cleanup-image /restorehealth while troubleshooting Windows errors. I want to know how it works and when it should be used. Does it repair corrupted system files or fix update problems? A clear explanation of its purpose and steps would really help.
