cumulative update

Microsoft released its January cumulative for Windows 11 (KB5074109) on January 13, 2026 — and within days a series of serious regressions began surfacing, from brief black screens on some Nvidia-equipped machines to full startup failures that print UNMOUNTABLE_BOOT_VOLUME (Stop Code 0xED) and...

Microsoft released the January 13, 2026 security baseline today — published as KB5074109 — and enterprise administrators should treat this as both a mandatory security checkpoint and a practical reminder about the new Hotpatch servicing cadence for Windows 11 Enterprise (24H2 and 25H2). The...

Microsoft’s December cumulative update for Windows 11 quietly flipped the AppX Deployment Service (AppXSVC) to an automatic startup, a change that Microsoft frames as a reliability improvement but which has already produced measurable headaches for some users and administrators — from spiking...

Microsoft released the final Patch Tuesday package for December 2025 — KB5072033 — and it arrives as more than a routine security rollup: it advances Windows 11 25H2 to Build 26200.7462 (and 24H2 to Build 26100.7462), ships deeper dark‑mode polish, centralizes virtualization controls in...

Microsoft has begun rolling out the January 12, 2016 cumulative update that raises Windows 10 (Version 1511) for non‑Insider PCs to build 10586.63 (delivered as KB3124263), a security‑focused release that patches multiple kernel, browser and remote‑code‑execution vectors and aligns public PC...

Microsoft has quietly closed out one of the oddest Windows 11 regressions of the year: an optional preview update temporarily turned Task Manager’s Close (X) into a lie, allowing invisible taskmgr.exe processes to pile up in the background — and the November cumulative has now fixed it...

Microsoft shipped a targeted Windows 11 quality update that finally closes the loop on a peculiar regression that left Task Manager processes running after the window was closed — a bug that could quietly accumulate orphaned taskmgr.exe instances and degrade system responsiveness over time...

I saw that 25H2 was available and installed it. And now I regret it because my installation has become a lot slower. When I look in the control panel under Windows Update the information is confusing. It says that 25H2 is installed but it also says that it is available for installation.

Microsoft’s October 2025 Patch Tuesday has brought a significant cumulative update to Windows 11 users: KB5066835, a mandatory security rollup that also flips on visible user-facing improvements for systems on the 24H2 and 25H2 servicing streams. The update ships as the October 2025 monthly...

Microsoft’s October deadline for Windows 10 support has arrived like a ringing bell for an industry that—by several measures—wasn’t ready: large numbers of consumer and corporate endpoints still run Windows 10, many organisations face compatibility and budget constraints, and the safety net...
