Microsoft announced optimizations to Windows 11 for developers at Build, including native Linux command-line utilities, WSL containers, an Intelligent Terminal, and simplified setup configurations. The updates deepen Linux integration to improve performance, reliability, and workflow consistency across environments.
The utilities ensure commands and workflows built over years continue to work when moving between Linux, macOS, WSL, containers, or cloud environments.
WSL containers provide a built-in way to create, run, and interact with Linux containers on Windows.

The Circuitry is a passion project I've always wanted to build, and I love the work behind it.
Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
CISA says it added Linux kernel flaw CVE-2026-46300 to its Known Exploited Vulnerabilities catalog on Oct. 28, with a federal deadline of Oct. 31 and forensic triage required. CISA says it can be chained with two PHP flaws to implant webshells and run commands as root.
Linus Torvalds released Linux kernel 7.3 with a record 18,765 non-merge commits from 3,021 developers. The update adds features including sched_ext completion, failfs, and fchroot() while the 7.4 merge window opens next.
Microsoft has begun rolling out Windows 11 version 26H2 as a small enablement package. The update resets support timelines and offers no exclusive new features for users already on recent versions.
CISA added Linux Kernel vulnerability CVE-2025-39682 to its Known Exploited Vulnerabilities catalog on 2026-09-18 with a federal remediation deadline of 2026-09-21. The flaw in the TLS receive path allows zero-length records to bypass recvmsg() handling, leading to incorrect processing assumptions, and agencies must apply vendor mitigations per BOD 26-04 or discontinue use of impacted EoL products.
Microsoft has suspended the July 2026 Windows 11 Patch Tuesday update on certain Dell models after it triggered unexpected shutdowns, sluggish performance, higher heat and fast battery drain. The flaw traces to an Intel driver clashing with a new USB-C Connection Manager interface; exact affected machines remain undisclosed while a fix is prepared.
