5 steps I took for a successful in-place upgrade of my 6-year-old PC from Windows 10 to 11

Windows 11 was released in October 2021. A user upgraded from Windows 10 22H2 to Windows 11 24H2 on a six-year-old HP Omen using an in-place upgrade. They backed up important files using OneDrive, Proton Drive, and a 4 TB external drive. The hardware was checked for compatibility with Windows 11 using Microsoft’s support page and the PC Health Check app. The user decluttered the system using Disk Cleanup and Revo Uninstaller. A system restore point was created for safety before the upgrade. The upgrade was initiated through Settings -> Update & Security -> Windows Update or the Windows 11 Installation Assistant, and it proceeded smoothly, allowing the user to keep files and applications.

5 reasons I use Windows 11 Backup over Macrium Reflect

Backups are crucial for data preservation, especially when primary machines face issues. Windows 11 provides various backup tools, including the Windows Backup app, which allows users to safeguard files, applications, and system preferences. This app can restore backups during Windows reinstallation and remembers wireless network credentials, simplifying the restoration process. It enables users to restore Microsoft Store apps with a single click and features a user-friendly interface that makes navigation easy. Windows Backup also offers data protection against ransomware through OneDrive storage. However, it cannot restore third-party apps and has limited cloud storage of 5GB on OneDrive, necessitating careful management of saved files.

These 7 WSL programs changed how I use Windows

Windows users previously faced challenges using Linux tools via virtual machines until the introduction of the Windows Subsystem for Linux (WSL), which was further improved with WSL2. WSL2 integrates a lightweight virtual machine into Windows, allowing users to run Linux applications seamlessly. Runtipi and CasaOS can be easily set up on WSL2 to host self-service applications without complex configurations. Visual Studio Code (VS Code) offers a WSL extension that enables code execution directly in Linux distributions from Windows, enhancing the coding experience. Gigolo is a frontend for managing network shares, which can also be integrated into Windows 11 through WSL2. Ansible can automate the provisioning of virtual machines and containers on WSL2, making it easier for users engaged in DIY projects. Rsync can be installed via WSL2 for efficient file synchronization and backups on Windows. Podman Desktop allows Windows users to explore container runtimes using WSL2, providing a GUI for managing containers. Lastly, WSL2 enables users to access the Linux terminal and run various Linux distributions directly within Windows 11.

Microsoft: Some devices offered Windows 11 upgrades despite Intune blocks

Microsoft is addressing an issue where some Windows devices are prompted to upgrade to Windows 11 despite Intune policies preventing such upgrades, a problem attributed to a "latent code issue" since April 12. A targeted code fix is being deployed, and users are advised to pause Windows feature updates via Intune until the resolution is fully rolled out. Users who upgraded to Windows 11 inadvertently will need to manually revert to their previous version. Additionally, in November 2024, certain Windows Server 2019 and 2022 devices were upgraded to Windows Server 2025 without user consent, and Microsoft acknowledged the problem but did not provide guidance on reverting these upgrades. Microsoft has also resolved an issue with prompts for upgrading to Windows Server 2025, clarifying that notifications were intended only for those seeking in-place upgrades.

Is using Google’s apps better than using the ones already on my phone?

Jerry, a tech professional with over 15 years of experience, addresses questions about Android and technology. He emphasizes the dual nature of preinstalled apps on Android phones, which can provide functionality but also clutter the user experience. He suggests that manufacturers should improve backup processes similar to Apple’s. Key apps recommended for Android users include Google Chrome, Google Messages, Google Photos, and Google Assistant. Alternatives to consider are Samsung's web browser, WhatsApp for messaging, Samsung's file browser, and music services like Spotify and Apple Music. Users are encouraged to explore app recommendations and experiment with different applications to enhance their smartphone experience.

Announcing pgvector 0.8.0 support in Aurora PostgreSQL

Amazon Aurora PostgreSQL-Compatible Edition has integrated support for pgvector 0.8.0, an open-source extension for storing vector embeddings in databases, enhancing its capabilities for generative AI applications, particularly in semantic search and retrieval-augmented generation. The new version improves the PostgreSQL query planner's index selection, elevating query performance and search result quality. It refines data filtering through WHERE clauses and joins, and features iterative index scans to prevent overfiltering, ensuring sufficient query results. Additionally, pgvector 0.8.0 enhances performance for searching and constructing HNSW indexes. This version is available in Amazon Aurora clusters on PostgreSQL versions 16.8, 15.12, 14.17, and 13.20 or higher, across all AWS Regions except China. Users can upgrade by modifying their DB cluster settings.

4 reasons I use virtual hard disks in Windows, and you should too

Creating virtual hard disks (VHD or VHDX) in Windows 11 23H2 and later is straightforward through the Settings app. Users can create a VHD by navigating to Settings -> System -> Storage -> Advanced storage settings -> Disks and volumes, where they can choose to create a VHD or Dev Drive. The VHD format supports up to 2040GB, while VHDX supports up to 64TB and offers resilience during power failures. VHDX can be encrypted with BitLocker for password protection. Virtual disks can be shared over a network, enhancing efficiency by eliminating the need for physical media. They are cost-effective compared to physical drives, reducing hardware costs and potential points of failure. The Hyper-V hypervisor provides a versatile platform for these virtual drives, which offer portability, flexibility, ease of sharing, efficient backups, and robust security, though they may have slower performance than SSDs and limited native boot support for Windows.

Exploitation of CLFS zero-day leads to ransomware activity

The Microsoft Threat Intelligence Center (MSTIC) and Microsoft Security Response Center (MSRC) identified a zero-day elevation of privilege vulnerability in the Windows Common Log File System (CLFS), designated as CVE-2025-29824. This vulnerability has been exploited by the PipeMagic malware, attributed to the group Storm-2460, affecting organizations in various sectors across the U.S., Venezuela, Spain, and Saudi Arabia. Microsoft released security updates on April 8, 2025, to address this vulnerability. The exploit allows attackers with standard user privileges to escalate their access, and it was executed from a dllhost.exe process. The exploit utilizes memory corruption techniques and the RtlSetAllBits API to gain all privileges and inject processes into SYSTEM processes. Post-exploitation, the attackers injected a payload into winlogon.exe, leading to ransomware activity characterized by file encryption and the creation of ransom notes. Indicators of compromise include the creation of a CLFS BLF file at C:ProgramDataSkyPDFPDUDrv.blf, command lines associated with ransomware activities, and specific domains linked to PipeMagic. Microsoft advises applying security updates promptly and recommends strategies for mitigating ransomware threats, including enabling cloud-delivered protection and utilizing device discovery.
