Microsoft has begun the staged rollout of Windows 11 version 25H2, delivering the update as a lightweight enablement package to devices already on the 24H2 servicing branch, but launch day has been accompanied by several regressions that—while narrow in scope—are serious for affected users and...

Today’s Canary-channel release of Windows 11 Insider Preview Build 27954 is a focused maintenance flight that fixes a handful of platform regressions while flagging a small set of high‑risk known issues that Insiders and developers must weigh before installing on active hardware. Background /...

Microsoft has quietly released the optional preview update KB5065790 for Windows 11 version 23H2 (Build 22631.5984), a compact quality rollup that fixes a handful of high‑impact reliability issues — notably a SIM PIN sign‑in freeze, multi‑monitor Remote Desktop shutdowns, problematic Chinese IME...

Microsoft shipped an unscheduled, out‑of‑band cumulative update for Windows 11 (KB5068221) to repair a high‑impact compatibility regression that caused Microsoft Office to fail when delivered via Microsoft Application Virtualization (App‑V), while also carrying forward September’s security fixes...

Microsoft has rolled out the KB5065790 Preview update for Windows 11 — a compact, non‑security “quality” rollup that fixes a cluster of high‑impact reliability issues, most notably an SMBv1 over NetBIOS (NetBT) file‑sharing regression and a Windows sign‑in freeze that affected WWAN/eSIM devices...

Microsoft released the September non‑security optional preview (the “C” release) update for Windows 11 under KB5065790 — a targeted cumulative quality rollup that addresses a handful of reliability problems ranging from a sign‑in freeze when entering a SIM PIN to display and printing glitches...

Windows 11’s September Patch Tuesday cumulative, KB5065426 (OS Build 26100.6584), has been linked to widespread file- and print-sharing failures on some machines, with multiple community threads and Microsoft Q&A posts reporting disabled sharing settings, networks switching from Private to...

Microsoft’s September cumulative for Windows 11, KB5065426 (OS Build 26100.6584), is proving to be a high‑priority security and quality rollup — and for a meaningful subset of users it’s also proving unusually stubborn: installs failing with a wide variety of error codes, long downloads, and in...

CIFS is not a modern alternative to SMB — it’s the 1996 dialect of SMB 1.0, and continuing to treat CIFS as a current protocol in 2025 leaves organizations exposed to well-known security flaws and performance shortfalls. The choice for any Windows-heavy network today is not “CIFS vs SMB” as if...

EternalBlue is not just another exploit in the cybersecurity hall of fame—it’s the infamous flaw that shook the digital world in 2017 and still resonates in security advisories today. Originally leaked by the hacker group The Shadow Brokers, this exploit was reportedly developed by the U.S...

I need just some clarifications: Is SMB (protocol) the only way to access remote shared folders (in small networks without Active Directory)? So whenever I want to list and use remote shared folders then SMB (either v1 or v2 or v3) must be enabled (on both computers). Correct?

I have two connected laptops standing side by side. One is running Windows 10, the other Windows XP. I need XP for some applications, and I am unable to convert them to Windows 10. Until recently I shared the disks of both machines using a LAN connection, allowing me to access the Windows 10...

As happened recently with WannaCrypt, we again face a malicious attack in the form of ransomware, Petya. In early reports, there was a lot of conflicting information reported on the attacks, including conflation of unrelated and misleading pieces of data, so Microsoft teams mobilized to...
