Charleston, breathe easy—we wrangled the week’s tech chaos into calm. The headline is a meaty Windows 11 update (with real, user-visible changes), plus urgent browser and Apple patches, fresh CISA vulnerability alerts, and a quick pulse check on GPU/laptop news for anyone planning upgrades before year-end.
News For The Week:
Windows 11 (24H2/25H2): October 28 “Preview” update now widely rolling out — here’s what’s actually new
https://support.microsoft.com/en-us/topic/october-28-2025-kb5067036-os-builds-26200-7019-and-26100-7019-preview-ec3da7dc-63ba-4b1d-ac41-cf2494d2123a
Microsoft’s KB5067036 (for 25H2 and 24H2) is an optional “C” update, but it’s a big one with features most folks will notice over the next few days as the gradual rollout expands. Highlights:
• File Explorer “Recommended” on Home (now for personal accounts too) to surface frequent/recent files; toggle it in File Explorer → Options.
• StorageProvider APIs so cloud providers can wire smarter suggestions into Explorer Home.
• Post-quantum crypto APIs (ML-KEM / ML-DSA aligned to FIPS 203/204) across CNG and .NET—future-proofing secure key exchange/signing.
• Fixes for driver install failures (0x80070103), authentication edge cases, and rendering quirks. These are explicitly called out in the change log. (Microsoft Support)
Two housekeeping notes from Microsoft’s release docs: update title formatting is now simplified in Windows Update, and there’s an early Secure Boot certificate expiration advisory for 2026—enterprises should plan certificate updates well ahead of time. (Microsoft Support)—◈—◈—◈—
Windows 11 health dashboard: known issue after late-October updates (Task Manager not fully closing)
https://learn.microsoft.com/en-us/windows/release-health/status-windows-11-24h2
Heads-up: closing Task Manager via the X button can leave a background instance running (extra taskmgr.exe processes), which can nibble RAM/CPU until you end them. Microsoft has the issue documented for 24H2 with mitigation guidance while a permanent fix rolls out. For now: if Task Manager acts odd, press Win+X → Task Manager, then End task on the zombie instance. (Microsoft Learn)—◆—◆—◆—
Windows 11 October security update recap (KB5066835): what it fixed and why it matters before November Patch Tuesday
https://support.microsoft.com/en-us/topic/october-14-2025-kb5066835-os-builds-26200-6899-and-26100-6899-1db237d8-9f3b-4218-9515-3e0a32729685
The October “B” release laid the security foundation that November will build on. If you paused updates, bring machines current first—out-of-band KB5070773 (Oct 20) piled on extra quality fixes. This sequencing helps avoid hiccups when November’s patches arrive this Tuesday. (Microsoft Support)—◐—◑—◐—
Chrome 142: security update is live—hit “Relaunch” to finish the job
https://chromereleases.googleblog.com/2025/11/stable-channel-update-for-desktop.html
Google shipped Chrome 142 with several security fixes. Visit chrome://settings/help and click Relaunch; Edge users should do the same via edge://settings/help as patches land on Chromium. Independent coverage notes specific point versions (142.0.7444.134/.135), but the key is to relaunch so the patched engine actually loads. (Chrome Releases)—◍—◌—◍—
Apple: big round of November security updates for iOS/iPadOS/macOS—update family devices
https://support.apple.com/en-us/100100
If iPhones/iPads/Macs touch your work (2FA, files, Messages), update to iOS/iPadOS 26.1 and the latest macOS releases from this week. Apple lists dozens of CVEs—good hygiene for mixed Windows/Apple households. Security notes for 26.1 are here; roll these alongside your Windows/Chrome updates this weekend. (Apple Support)—△—▲—△—

BitLocker recovery prompts after Windows updates: what’s going on & how to prepare
https://www.tomshardware.com/software/windows/windows-security-update-triggers-bitlocker-recovery-in-some-systems-bug-mostly-impacts-intel-pcs-with-modern-standby-support
Some systems (especially Intel laptops with Modern Standby) may boot to BitLocker recovery after certain October updates. It’s typically a one-time prompt; have your recovery key ready via your Microsoft account or MDM. SMB tip: export keys to a safe, offline place and verify them quarterly. (Tom's Hardware)—○—●—○—
Hardware watch: AMD flags risk from the new Intel–Nvidia tie-up

Windows 11 version 23H2 reaches end-of-support this week—time to move
https://learn.microsoft.com/en-us/windows/release-health/windows11-release-information
Reminder: Windows 11 23H2 hits end-of-support on November 11, 2025 (consumer editions). If “winver” shows 23H2 or earlier, plan your jump to 24H2 or 25H2 now. (Enterprise/Education timelines differ.) We can check compatibility, handle backups, and schedule upgrades after hours. (Microsoft Learn)
For additional context, here’s a mainstream explainer that ran last week. Bottom line: don’t sit on 23H2. (Windows Central)—◇•◇—
Windows Tips For The Week:
- Which update first? Install the October security update (KB5066835) or later (including the Oct 20 OOB KB5070773) before taking the KB5067036 preview, then reboot twice. This sequence reduces weird edge-cases. (Microsoft Support)
- Turn on (or off) File Explorer “Recommended.” Explorer → View → Show → Recommended (or File Explorer → Options). If you don’t like suggestions on Home, toggle it off. (Microsoft Support)
- Chrome/Edge patching discipline. Go to chrome://settings/help (or edge://settings/help) and click Relaunch—updates don’t fully apply until you do. Target: Chrome 142. (Chrome Releases)
- BitLocker recovery sanity check. Confirm your recovery keys: Settings → Privacy & Security → Device encryption → BitLocker (or in your Microsoft account). Export keys for each laptop to a safe spot. (Tom's Hardware)
- On 23H2? Type winver. If it says 23H2, plan your upgrade before Nov 11. We can inventory, back up, and move you to 24H2/25H2 with minimal downtime. (Microsoft Learn)
AI Prompt Ideas:
“One-Page Upgrade Plan (Windows 11 24H2/25H2)”
You are my virtual IT planner. Using my PC list (CPU/RAM/OS) and budget, produce a one-page plan to move any Windows 11 23H2 or Windows 10 machines to 24H2/25H2 or replacements. Include: priority order, estimated costs, downtime per device, and a 5-step pre-flight checklist (backups, BIOS/firmware, disk health, app compatibility, rollback point). Keep it friendly and Charleston-local.
