A user reports that their desktop operating system has not been able to install the latest updates. Upon checking, you notice that the update process begins but then rolls back with an error stating insufficient disk space. Before attempting to free up space, which of the following should be the first step to resolve the update issue?
Disable antivirus software to prevent it from interfering with the update process.
Check the available disk space to confirm if it aligns with the error message.
Perform a clean boot to eliminate software conflicts that might block the update.
Perform a disk defragmentation to free up space and potentially resolve the issue.
