Microsoft is initiating a 12-month retirement period for support of Windows PowerShell 5.1 for the Microsoft Graph PowerShell SDK due to maintenance challenges. Organizations using Graph PowerShell automation on Windows PowerShell 5.1 may face disadvantages, as existing scripts will remain operational but will miss platform-specific bug fixes. Microsoft encourages a transition to PowerShell 7.x, which will be the focus of Graph PowerShell v3.0, set to launch in Q4 2026. During the retirement phase, Graph PowerShell v2.x will remain operational and receive security updates. Transitioning to the new SDK version may require migration planning, script validation, and runtime upgrades, especially for organizations with dependencies on older PowerShell runtimes or outdated components.

Windows retains thumbnails in a cache file named thumbcache_256.db, but it does not save a thumbnail of every deleted photo. Other operating systems, including macOS and Linux, also use thumbnail caching. Users can access their thumbnail cache by navigating to %LOCALAPPDATA%MicrosoftWindowsExplorer, but this will not show deleted images. Thumbnails are created only when images are displayed in Explorer’s thumbnail view. Windows allows users to clear the thumbnail cache using the Disk Cleanup tool, and there is an option to disable thumbnail caching in Windows 11 Pro and higher. The cached thumbnails do not guarantee persistence and do not represent original files. Windows also keeps records of application launches in Prefetch, maintains entries for USB devices in the USBSTOR registry key, saves Wi-Fi networks and passwords, and can keep clipboard history and recent file shortcuts.

Microsoft's Windows 10 update "KB5126256," intended as a licensing preparation package for Extended Security Updates, has caused issues for users, including one Reddit user whose File Explorer crashes when clicking on files due to the automatic activation of the Copilot feature. The crashes were misleadingly attributed to Microsoft Edge, but further investigation revealed they were linked to "mscopilot_proxy.exe" and the module "ShellEh6055x64.dll," associated with the 4t Tray Minimizer application. Users have reported that uninstalling problematic updates can provide temporary relief, while some have chosen to disable updates entirely, despite Windows not offering a complete option to do so.

A recent post on X claims that Windows retains a thumbnail of every deleted photo in a file named thumbcache_256.db, which has raised privacy concerns among users. While Windows does maintain a thumbnail cache for efficiency, this practice is not unique to Windows, as other operating systems like macOS, Linux, and Android also use similar systems. Users can inspect or clear their thumbnail cache by accessing specific database files in the Windows Explorer directory. The claim that Windows retains "every photo you’ve ever deleted" is misleading, as thumbnails are only created when images are viewed in thumbnail mode. Windows does not cache every file, and thumbnails must exist before they can be cached. Additionally, Windows keeps app launch records in Prefetch files for performance optimization, maintains entries for USB devices in the USBSTOR registry key, retains records of Wi-Fi networks and passwords (which are encrypted), and can keep clipboard history and recent file shortcuts. Caching previews is common across various operating systems, and Microsoft is focused on user consent and privacy as it enhances Windows 11 with AI functionalities.

Two newly identified Critical CVEs have expanded Microsoft's September identity infrastructure vulnerabilities to over ten verified weaknesses across more than ten distinct services. The Azure Database for PostgreSQL is vulnerable to CVE-2026-85878, an Improper Authorization flaw (CWE-285) with a CVSS score of 9.9. Azure Billing is impacted by CVE-2026-62874, which presents an Insufficient Data Authenticity Verification issue (CWE-345) with a CVSS score of 10.0. Both vulnerabilities were disclosed on September 18 and validated by Tenable and MITRE. CVE-2026-85878 allows an authorized attacker to elevate privileges over the network with minimal complexity, while CVE-2026-62874 requires no authentication, enabling unauthenticated attackers to jeopardize financial integrity. The vulnerability cluster first emerged during the Patch Tuesday cycles on September 3 and September 8, with initial reports highlighting critical flaws in core services. Other September disclosures include CVE-2026-83711 (Azure AD B2C, CVSS 10.0), CVE-2026-70352 (Azure AI Language, CVSS 10.0), CVE-2026-83941 (Entra ID, CVSS 9.9), CVE-2026-62916 (Entra ID, CVSS 9.1), CVE-2026-69857 (Azure Cosmos DB, CVSS 8.5), and CVE-2026-69854 (Spring Cloud Azure, CVSS 9.0). Activity heightened between September 17 and 18 with the introduction of CVE-2026-77903 (Microsoft Dataverse, CVSS 9.0) and CVE-2026-69843 (Microsoft Fabric, CVSS 10.0). The attack surface has broadened from authentication concerns to encompass trust in AI endpoints, data storage locations, and billing verification processes. Seven out of the ten vulnerabilities are unauthenticated, and all issues were addressed through server-side fixes by Microsoft. The extensive range of affected services suggests these vulnerabilities indicate a shared architectural dependency on authentication logic.

Postgres Women India was launched in 2023 as a corporate social responsibility initiative under OpenSource DB, starting with 10 members and growing to over 2000 women across more than 70 countries. The community addresses the underrepresentation of women in open source and database conferences, aiming to empower, connect, and celebrate women in technology. Its core pillars include community building, nurturing future leaders, and advocating for education. The community organizes virtual and in-person meetups, mentorship programs, and collaborates with universities to enhance skills in database technologies. Key initiatives include a Career Connect Day, intensive upskill programs, and the Women for Data Summit. The community has recognized 18 women as ‘Postgres Women of the Month’ and highlighted emerging contributors. Partnerships with organizations like Google and YugaByteDB support its efforts, and it seeks further community involvement to establish local chapters and host events.
