Exchange Online administrators across multiple tenants are reporting a troubling and repeatable symptom: attempts to change Public Folder permissions are being rejected with access-denied or “permission change is denied” errors, and the problem appears to have affected multiple tenants over the...

Mozilla's latest posture on legacy Windows is a study in trade-offs: the organization will continue shipping security patches for Firefox 115 ESR to machines still running Windows 7, Windows 8, and Windows 8.1 — but it admits doing so is increasingly expensive, fragile, and ultimately risky for...

Mozilla has quietly given Windows 7 and its siblings another lease on life by keeping the Firefox 115 Extended Support Release (ESR) safety net open for a little while longer — but that extra time is both a pragmatic lifeline for legacy users and a final countdown that IT teams and hobbyists...

Microsoft’s Exchange engineering team has told administrators there are no security updates for on‑premises Exchange Server this month — an explicit, scheduled announcement that matters because a subset of customers remain on the vendor’s short, paid Extended Security Update (ESU) runway that...

Microsoft’s Windows 11 has reached a turning point: according to public telemetry, it now runs on nearly three out of every four Windows PCs worldwide — a seismic shift that reshapes the desktop landscape for users, IT teams, developers, and the PC hardware market. StatCounter’s February 2026...

Mozilla’s decision to stop providing security updates for Firefox on Windows 7, Windows 8 and Windows 8.1 marks the end of the browser’s long-running role as the last major line of defense for users still running those older Microsoft platforms. The practical result: Firefox 115 (the Extended...

From the first boot, AnduinOS does something most Linux remixes only pretend to do: it matches Windows behavior in places that matter, not just the wallpaper and icons, and that simple design decision makes it one of the most convincing escape routes from Windows yet. Background / Overview...

Mozilla has drawn a clear line under one of the last ongoing safety nets for legacy Windows desktops: Firefox 115 (ESR) is the final Firefox build that will run with official security updates on Windows 7, Windows 8, and Windows 8.1, and Mozilla’s Extended Support Release maintenance for that...

Microsoft has confirmed that three high‑usage Windows releases first shipped in 2016 will reach the end of their official support lifecycles within the next year — and that organizations still running them will face a stark choice: upgrade, migrate to cloud‑hosted alternatives, or pay for...

Microsoft has confirmed a measured — and expensive — safety net for organizations that are still running Windows 10 Enterprise LTSB 2016 and Windows 10 IoT Enterprise LTSB 2016, and it has signaled more uncertainty for Windows Server 2016 customers by scheduling end-of-support dates and...

If your organization still runs Windows Server 2016 or Windows 10 Enterprise / IoT Enterprise 2016 LTSB, you need an urgent, concrete plan: these 2016 releases are reaching their final support milestones and will stop receiving regular security updates unless you take action before the...

Mozilla’s long-running safety net for older Windows desktops is being withdrawn: Firefox 115 (the last build that will run on Windows 7, Windows 8, and Windows 8.1) will no longer receive routine security updates after the ESR maintenance window closes in late February / early March 2026...

Mozilla’s support path for users running pre–Windows 10 desktops has reached a clear milestone: Firefox 115 ESR will be the last maintained Firefox build for Windows 7, Windows 8 and Windows 8.1, and Mozilla’s support documentation now states that security updates for those legacy installations...

Exchange Web Services in Exchange Online is being retired, and the clock is now unmistakably ticking: Microsoft will begin tenant-by-tenant disablement starting October 1, 2026, with a final, irreversible shutdown of EWS in Exchange Online in 2027. This move completes a deprecation that began...

Microsoft has quietly moved another piece of the Creators-era toolbox onto the chopping block: 3D Viewer — the lightweight Windows app for inspecting 3D models — was marked deprecated in February 2026 and is scheduled to be removed from the Microsoft Store on July 1, 2026. Existing installations...

Microsoft has quietly moved another piece of its once‑ambitious 3D strategy onto the chopping block: 3D Viewer — the lightweight model inspector that shipped with Windows 10 and served as Microsoft’s simple bridge for viewing and inspecting glTF, OBJ, FBX and other model formats — was formally...

Windows 11 reaching one billion users — and doing it faster than Windows 10 — is the kind of headline that gets product teams, OEM partners, and IT departments talking. Microsoft quietly confirmed the milestone during its fiscal Q2, 2026 commentary, and company executives have since framed the...

Microsoft has quietly drawn a line under one of the longest‑lived branches of Windows: the Vista‑derived codebase that powered Windows Server 2008 has reached the absolute end of vendor‑supplied security updates, with the final paid lifecycle option (Premium Assurance) closing on January 13...

Microsoft has formally closed the book on the Windows Vista / Windows Server 2008 codebase: on January 13, 2026 the last vendor‑issued update pathway for that lineage expired, removing the final paid support channel that had kept Critical and Important security fixes flowing for a dwindling set...

Microsoft has finally torn off the bandage: the last vendor-supplied security updates for the Vista‑era Windows codebase — most notably Windows Server 2008 — have ended with the expiration of Microsoft’s Premium Assurance commitments on January 13, 2026. This final cutoff completes a long...
