C. Initiate the system restore:

If the technician is confident that rolling back the system to a previous restore point will resolve the issue, the next logical step is to initiate the System Restore process.

System Restore allows the system to revert to a state before the OS update, which can eliminate the performance issues caused by the update.

Incorrect Options:

A. Document the findings: Documentation is important but should occur after resolving the issue.

B. Investigate any recent infrastructure changes: This is unnecessary if the issue is already attributed to the OS update.

D. Verify full system functionality: This step should be performed after the System Restore is completed.

Key Takeaway: When confident that rolling back will resolve the issue, the technician should proceed with initiating a System Restore to revert the OS.
