System Restore is a recovery tool in Windows that allows users to revert their systems to a previous state, originating with Windows ME. It generates restore points that can be created manually or automatically, with a maximum retention of 60 days starting from the Windows 11 24H2 update in 2025. System Restore captures essential system files and settings but does not recover personal files. The new Point-in-Time Restore feature, introduced in 2025 and appearing in the Windows 11 Insider Experimental preview in April 2026, captures a broader range of data, including user files and applications, and operates on a scheduled basis with snapshots retained for up to 72 hours. It is optional for standard users, enabled by default for PCs with 200GB or more storage, and has storage limits set to 2% of total drive capacity. In enterprise settings, it is always enabled for Windows 365 Enterprise, maintaining restore points for up to one month and utilizing cloud storage. Point-in-Time Restore aims to improve the recovery experience and address limitations of the classic System Restore.

On April 30, 2026, Microsoft Defender misclassified two legitimate DigiCert root certificates as a severe threat, specifically Trojan:Win32/Cerdigent.A!dha, leading to their quarantine and disrupting SSL/TLS validation across affected endpoints. This misclassification was a result of new malware detections introduced by Microsoft in response to concerns over compromised certificates from a DigiCert breach. The false-positive alerts were triggered by the registry entries of the two trusted root certificates, which are crucial for validating SSL/TLS sessions. Microsoft later acknowledged the error and adjusted the alert logic. There was no actual compromise of the DigiCert certificates, as administrators confirmed that the certificate hashes matched the official values. The misclassification stemmed from a failure to properly constrain the detection to only revoked end-entity signing certificates related to a separate incident. This incident follows a pattern of Microsoft Defender misidentifying legitimate software as malicious, as seen in a 2022 incident where Microsoft Office was flagged as a virus. Organizations with restrictive update policies may continue to face SSL/TLS validation failures until they deploy the corrective Security Intelligence version or manually restore the DigiCert roots.

Microsoft has acknowledged that some Windows 11 updates may require multiple reboots, particularly those related to Secure Boot certificates, which are essential for system security. These updates aim to protect against malware, especially rootkits, and ensure the effective functioning of Secure Boot. Some users have faced difficulties in receiving the new certificates due to firmware issues, but multiple reboots typically indicate that necessary security enhancements are being applied.
