Windows 11 can keep thumbnails of photos you deleted. Here’s how to remove them

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.

What Is Happening with PostgreSQL 19?

Postgres 19 is experiencing delays in its release schedule, with Beta 4 scheduled for September 24, 2026. The development team is prioritizing quality over timelines, leading to the reversion of 53 significant features during the beta phase. Notable feature reversions include SQL Property Graph Queries, ALTER TABLE MERGE/SPLIT PARTITION(S), UPDATE/DELETE FOR PORTION OF, GROUP BY ALL, a change to default TOAST compression, nontext output formats for pg_dumpall, JSON_TABLE ON ERROR cascading, fast defaults for domains with nonvolatile constraints, logical replication database-specific snapshots, nested query tracking, and online data checksums. The majority of these reversions are due to design flaws, incorrect results, or compatibility issues. There are also at-risk features identified, including RI fast-path FK checks, REPACK / REPACK CONCURRENTLY, and Postgres_fdw statistics import. Despite these challenges, promising features such as pg_plan_advice, parallel autovacuum, ON CONFLICT DO SELECT, and logical replication enhancements are still anticipated in PG19. AI tools are being utilized in the development process to identify bugs and create test cases. Postgres 18 remains a reliable upgrade target, while features like property graphs and GROUP BY ALL are now planned for PG20.

The Fault Line Spreads: Azure’s September CVE Cluster Now Covers PostgreSQL and Billing

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.
