How and why we built Managed PostgreSQL for AI workloads

The Nebius Managed PostgreSQL team developed a solution for AI workloads using CloudNativePG and Kubernetes, resulting in improved backup and restore times by transitioning from Barman to WAL-G, reducing a 1.5 TB backup duration from over a day to two hours. Since its launch in 2025, the service supports hundreds of production clusters and manages tens of tebibytes of data. Key features include high availability, point-in-time recovery, automated failover, compressed and encrypted backups, rapid restoration, connection pooling, and strict synchronous replication for zero data loss. Kubernetes and CloudNativePG were chosen for their advantages, including out-of-the-box features and open-source distribution. Each cloud project has a separate MK8s cluster for customer isolation and security. Persistent data is stored on fault-tolerant SSD drives, enabling swift instance migration during failures. Regular physical backups are archived, allowing restoration within a seven-day window with a single click. The transition from Barman to WAL-G addressed slow backup and restoration times and resource control limitations. With WAL-G, backups and restorations for a 1.5 TB cluster improved to two hours and one hour, respectively. PgBouncer was implemented to manage database connections effectively, reducing connection storms during peak AI workload traffic. Two vector search extensions, pgvector and pgvectorscale, are available to cater to different memory and dataset needs. Benchmarking showed that Nebius performs competitively with AWS at a lower cost. The infrastructure integrates cloud engineering principles with specialized expertise to meet AI workload demands.

How Telangana’s MeeSeva migration to open source could make governments rethink software costs

In April 2026, Telangana's MeeSeva platform migrated from the Oracle database to the open-source PostgreSQL database after 15 years of reliance on Oracle. This transition aimed to reduce annual costs of approximately ₹10 crore associated with Oracle licensing and maintenance. The initiative began in 2023, and the migration was executed with less than four hours of downtime, processing around 80,000 transactions daily. The migration involved over 85 microservices, three Oracle servers, and 1,939 tables, with the process automated by the Ora2Pg tool, which handled 60-70% of the transition. The migration cost was below ₹10 lakh, and after the switch, MeeSeva processed nearly 200 million transactions without data loss. The new architecture includes automatic failover capabilities to minimize disruption.

Microsoft confirms a Windows update can close games that use AC-3 audio

Microsoft has acknowledged an issue related to a Windows update (KB5124010) released on September 22, 2026, which has caused unexpected closures of various games that rely on AC-3 audio decoding. This issue affects Windows 11 versions 24H2, 25H2, and 26H2, while server editions remain unaffected. The problem primarily impacts legacy applications that depend on Windows' built-in audio decoding, particularly older PC games using the Dolby Digital codec for pre-rendered cutscenes and licensed soundtracks. Microsoft has confirmed the issue but has not provided a list of affected titles, workarounds, or a resolution timeline. The status remains unchanged as of October 7, and the issue persists regardless of user action.

Microsoft: Recent Windows updates cause desktop loading issues

Microsoft has acknowledged that some users may experience desktop loading issues, specifically black screens, after installing the August 2026 preview updates and subsequent releases. This problem mainly affects Azure Virtual Desktop (AVD) hosts using FSLogix. Symptoms include a black screen post-sign-in and crashes related to Windows Explorer, which can be temporarily resolved by manually launching Windows Explorer through Task Manager. For enterprise customers, Microsoft has introduced a mitigation strategy via Known Issue Rollback (KIR), allowing IT administrators to reverse problematic updates by applying specific group policies. Additionally, Microsoft has addressed issues related to the loss of mouse and desktop settings on certain Windows 11 systems caused by the KB5120998 update.

Windows 10 is more stable than Windows 11 in 2026, data shows

The September update for Windows 11 caused significant disruptions, including failures in USB audio functionality and the File History feature. This follows a trend of issues over the past months, with August experiencing printer and PDF problems, July affecting certain Dell PCs, and June reporting startup issues and BitLocker recovery failures. In total, eight out of nine months this year have had at least one major issue. A recurring BitLocker user lockout problem has also been noted. Despite these issues, Windows 11 has improved in overall stability, with fewer system crashes. Windows 10 has maintained stability by focusing solely on security updates since support ended in October 2025, avoiding new feature rollouts. Users satisfied with Windows 10's features may prefer to stay with it for stability. Windows 11 users facing instability can roll back updates or use the Known Issue Rollback feature to revert problematic non-security features.

Windows update leaves some virtual desktops staring into the void

Microsoft has acknowledged an issue affecting some Windows 11 users utilizing virtual desktops, where a black screen appears after sign-in, requiring manual launch of Explorer to regain access. This glitch is linked to devices operating on the August 2026 non-security preview update or later. It has been predominantly observed on Azure Virtual Desktop (AVD) hosts using FSLogix, with crashes of Windows Explorer noted in the Application event log. A temporary workaround involves using Task Manager to initiate explorer.exe as a new task. Microsoft has implemented a Known Issue Rollback (KIR) via Group Policy to disable the problematic change until a permanent fix is released. Versions 26H1, 25H2, and 24H2 of Windows 11 are affected, while Windows 10 and Windows Server do not appear to be impacted.
How to Use Point-in-Time Restore in Windows 11

How to Use Point-in-Time Restore in Windows 11

The Point-in-Time Restore feature in Windows 11 allows users to revert their system to a previous state, but it may result in the loss of recently created files. This feature captures the system's state, including Windows system files, installed applications, and local settings. Restore points are generated automatically every 24 hours, but users can create them manually. However, restoring can erase new documents, recently installed applications, and any settings changes made since the last restore point. Files stored in OneDrive remain unaffected. To verify Point-in-Time Restore settings, users must access the Settings application, select System, and then Recovery. Restore points are retained for up to 72 hours and may be deleted sooner if storage is limited. Windows 11 version 26H2 enables this feature by default for devices with an OS volume of at least 200 GB. Before restoring, users should back up recent work to an external drive. To initiate the restore, access the Windows Recovery Environment, select Troubleshoot, and then Point-in-Time Restore. If files are lost after a restore, 4DDiG Data Recovery Software can help recover deleted files. It scans local drives for files deleted during a rollback or accidental deletion. A robust recovery plan should include using Point-in-Time Restore, OneDrive for daily file protection, and separate backups before significant system changes.
