Achieve up to 1.7 times higher write throughput and 1.38 times better price performance with Amazon Aurora PostgreSQL on AWS Graviton4-based R8g instances

Upgrading to Graviton4-based R8g instances with Aurora PostgreSQL-Compatible 17.4 in an Aurora I/O-Optimized cluster configuration results in significant performance improvements. The new instances provide up to 1.7 times higher write throughput, 1.38 times better price-performance, and reduce commit latency by up to 46% on r8g.16xlarge instances and 38% on r8g.2xlarge instances compared to Graviton2-based R6g instances. The Amazon Aurora PostgreSQL-Compatible Edition now supports AWS Graviton4-based R8g instances and PostgreSQL 17.4, which introduces performance enhancements for I/O-Optimized configurations, optimizing write operations and batch processing. R8g instances offer up to 192 vCPUs and 1.5 TB of memory, supporting larger configurations and providing up to 50 Gbps of network bandwidth. PostgreSQL 17 includes vacuum improvements, eliminates the need to drop logical replication slots during upgrades, and expands SQL/JSON standards. Aurora PostgreSQL-Compatible separates compute from storage, enabling independent scaling and maintaining six-way replication for durability, while processing changes as log records to reduce I/O operations. Performance benchmarks using HammerDB show improvements in throughput and commit latency across various workloads. For small workloads on 2xlarge instance size, throughput increased by 50.25% and commit latency improved by 33.87%. For medium workloads on 16xlarge instance size, throughput increased by 30% and commit latency improved by 17.44%. The most significant performance benefits arise from combining hardware upgrades from Graviton2 to Graviton4 with database engine upgrades from PostgreSQL 15.10 to 17.4. For small workloads, throughput increased by 70% and commit latency improved by 38.71%. For medium workloads, throughput increased by 70% and commit latency improved by 46.67%. Cost efficiency is also enhanced, with a 38% improvement in price performance and a 61.26% improvement in price-performance ratio when comparing Graviton2 and Graviton4 instances. Reserved Instances for Graviton4-based R8g instances offer additional cost-optimization opportunities.

Microsoft Triumphs: Resolves Long-Standing Windows Bug from Last Year

Microsoft's latest Windows 11 update, version 24H2, released in May 2025, resolves a dual-boot issue caused by the Secure Boot Advanced Targeting (SBAT) feature that made Linux partitions unbootable for many users. Additionally, Microsoft has launched a new 13-inch Surface Laptop, which is the lightest and thinnest version ever produced, weighing 2.7 lbs, and emphasizing portability and performance with advanced AI features.

Microsoft finally squashed a Windows bug that’s been around since last year

Microsoft has resolved a dual-booting issue caused by a patch released in 2024 that incorrectly applied Secure Boot Advanced Targeting (SBAT) settings to custom dual-boot configurations, preventing users from booting into Linux. This issue has been fixed in the May 2025 Windows 11 update (version 24H2), allowing seamless dual-booting. Additionally, Microsoft launched a new 13-inch Surface Laptop, which is the lightest and thinnest laptop the company has produced, weighing 2.7 lbs and featuring enhanced performance and advanced AI capabilities.

Microsoft is testing a new ‘Advanced Settings’ page in Windows

Microsoft is testing a revamped "Advanced Settings" page for its Windows Server operating system, which will replace the previous "For Developers" page. This new page aims to improve user accessibility by including features beneficial to a wider audience, such as the "End Task" option. It introduces a "long path" setting that removes the 260-character limitation on file paths, helping users avoid the "Path too long" error. The changes are currently exclusive to Windows Server but may extend to Windows 11 within the calendar year.

Microsoft fixes bug causing incorrect 0x80070643 WinRE errors

Microsoft has resolved a known issue causing 0x80070643 installation failure errors during the deployment of the April 2025 Windows Recovery Environment (WinRE) updates. This issue affected the KB5057588 update for Windows Server 2022 and the KB5057589 update for Windows 10, versions 22H2 and 21H2. The error message was misleading, as it did not reflect the actual status of the update or the device's performance. The error typically occurred when a device attempted to install the WinRE update while another update was pending a reboot. Microsoft confirmed that users will no longer see the incorrect error message after installing the affected updates. Additionally, in August of the previous year, Microsoft retired the January 2024 Windows security updates that also triggered 0x80070643 errors during WinRE updates. During that time, fraudulent IT support websites promoted malicious PowerShell "fixes" for these errors, leading to malware infections among users.

I tried installing Windows on an ReFS drive, and I actually don’t hate it

Microsoft has been developing a new file system called ReFS (Resilient File System) to eventually replace NTFS. Users can boot Windows 11 from an ReFS drive, but the setup process is complex and requires formatting the drive using the Command Prompt. After installation, Windows 11 operates normally on ReFS, offering advantages in data resiliency and durability, especially for virtual hard disks and Storage Spaces. However, performance tests show that ReFS is slower than NTFS across various metrics, indicating it may not provide speed enhancements for general use. ReFS is seen as a promising alternative to NTFS, with potential future improvements in performance, particularly for specialized workloads.

How to keep using Windows 10 in a virtual machine after support ends

Microsoft will end support for Windows 10 on October 14, 2025. Users can run Windows 10 in a virtual machine (VM) to continue using it safely. The tool Disk2Vhd can convert a physical Windows 10 installation into a virtual hard drive (VHD or VHDX) for use in virtualization software like VirtualBox or Hyper-V. To use Disk2Vhd, download and extract it, launch the appropriate executable, select partitions for conversion, and choose between VHD and VHDX formats based on the virtualization software. After conversion, transfer the VHD file to the target computer and set up a new VM, integrating the backup file instead of creating a new virtual hard drive. Users can also reinstall Windows 10 in a VM using an installation medium and the Media Creation Tool to download the ISO file. When creating a VM, allocate at least 4GB of virtual memory and install necessary programs and guest extensions afterward. Creating a backup point after installation is recommended for stability.

Microsoft tells Windows users to ignore 0x80070643 WinRE errors

Microsoft has acknowledged that some users may experience installation failures with error code 0x80070643 when deploying the April 2025 Windows Recovery Environment (WinRE) updates, specifically affecting the KB5057589 update for Windows 10 versions 22H2 and 21H2, and the KB5057588 update for Windows Server 2022. The company stated that this error is misleading and does not affect device functionality, as the WinRE update is typically applied successfully after a device restart. Users may see a failure indication in Windows Update, but this will be resolved after the next daily scan and restart. Microsoft is working on a resolution for this issue, which follows a similar situation from August 2024. Additionally, fraudulent IT support websites have been identified promoting malicious PowerShell "fixes" for these errors.

4 reasons you should embrace virtual machines instead of jumping straight to dual-booting

Operating multiple systems on a single machine, particularly Windows and Linux, can be achieved through dual-booting or using a virtual machine (VM). Dual-booting can lead to complications, such as Windows obstructing access to Linux and overwriting Linux's boot manager. In contrast, VMs allow users to run multiple operating systems concurrently without rebooting, making them more flexible and user-friendly. VMs facilitate the management of separate environments for different tasks and can be easily deleted and recreated if needed. They also provide enhanced security by operating in a sandboxed environment, reducing the risk of damage to the primary system. VMs are portable, encapsulated in a single file for easy transfer between computers, and support snapshots for quick rollbacks.
