Windows 11 Point-in-Time Restore is a recovery feature that captures snapshots of the system's state, including system files, applications, settings, and user data, allowing users to revert to a recent stable state when issues arise. It operates automatically once activated, using Volume Shadow Copy technology for comprehensive backups. The feature can quickly reverse changes made within the last 72 hours, addressing problems like faulty driver installations without requiring a complete reinstallation of Windows. However, it has limitations, such as storing restore points locally for a maximum of 72 hours, not recovering long-deleted files, and requiring significant storage space. To enable it, users must use ViveTool to unlock the feature, configure settings for snapshot frequency and retention, and access restore options through the Windows Recovery Environment if needed. It is particularly useful for casual users who frequently modify their systems but may not suffice for power users needing comprehensive backup solutions.
