Manage Hyper-V VM Checkpoints
How Hyper-V checkpoints actually work (differencing-disk chain), when to use them (lab rollback, patch dry-run, demo reset, short-term oh-no insurance), why they aren't a backup, the Production vs Standard distinction (default Production - app-consistent via VSS - safe for most workloads except DC/SQL/Exchange replicas), the GUI flow for create / revert / apply / merge, the Edit Disk wizard for manual merge of orphaned chains, the PowerShell equivalents (Checkpoint-VM, Restore-VMSnapshot, Remove-VMSnapshot), and 7 common pitfalls (don't snapshot a DC, USN rollback, long-lived checkpoints, disk-space crunch, revert vs running VM).
