Explain the difference between automatic approval rules and manual approval in WSUS.

Automatic Approval Rules:

• Pre-configured rules that automatically approve updates based on specific criteria
• Can be set based on update classification (Critical, Security, etc.)
• Can target specific computer groups
• Reduces administrative overhead for routine updates
• Example: Auto-approve all "Critical Updates" for the "Test Servers" group

Manual Approval:

• Administrator manually reviews and approves each update
• Provides maximum control over which updates are deployed
• Allows thorough testing and evaluation before approval
• Recommended for production environments or critical systems
• Can approve for installation, download only, or decline

Best practice is to use automatic rules for test environments and manual approval for production systems.
