Microsoft asks users to ignore Windows Firewall config errors

Microsoft asked customers this week to disregard incorrect Windows Firewall errors that appear after rebooting their systems following the installation of the June 2025 preview update. These warnings are logged in the Event Viewer as 'Event 2042' for Windows Firewall with Advanced Security, with a 'Config Read Failed' warning and a 'More data is available' message. Microsoft added that this known issue is caused by a new feature that's still under development and hasn't yet been fully integrat

Microsoft's 'Blue Screen of Death' Dies After 40 Years: Meet Its Replacement

Like Pudding Pops and Benetton sweaters, another 1980s icon is gone. After 40 years of delivering the tragic news of a PC crash to Windows users, Microsoft's infamous "blue screen of death" is going away. A black screen of death will be replacing it, albeit without the sad face. The blue screen of death has been around since Windows 1.0 came out in 1985. Named for its bright blue color, it's a critical error screen that pops up on computers using the Microsoft Windows operating system when the

Windows 11 should have been an easy upgrade - Microsoft chose to unleash chaos on us instead

Matthias Kulka/Getty Images In my three-plus decades of watching Microsoft, I've seen the company do some truly dumb things. The transition from Windows 10 to Windows 11 deserves a spot at the top of the list. What's most impressive is that the strategy it's been executing is bad for Microsoft's customers, and bad for the company's bottom line. A real lose-lose proposition.

Microsoft fixes ‘Print to PDF’ feature broken by Windows update

Microsoft has fixed a known bug that breaks the 'Print to PDF' feature on Windows 11 24H2 systems after installing the April 2025 preview update. "Specifically, the Microsoft Print to PDF printer might no longer appear under Settings > Bluetooth & devices > Printers & scanners," the company explains in updates added to support documents for Windows updates released since April. "You might also notice that enabling the Printing-PrintToPDFServices-Feature returns error code 0x800f0922, which pre

How to clear the cache on your Windows 11 PC (and why you shouldn't wait to do it)

Kyle Kucharski/ZDNET If your computer desktop looks a little chaotic and you're noticing some performance slowdown, it might be time to do a cleanup. The best way to keep things running smoothly is to ensure you're running the most updated version of Windows (you'd be surprised how many folks' devices are several updates behind). But if you're up-to-date, there are other things you can do to optimize. Also: This compact Windows PC outperforms the M4 Mac Mini in key areas - and it's on sale Wi

Sliding Window Technique Visualizer

A fixed-size sliding window maintains a constant size as it moves through the data structure. This is useful for problems like finding the maximum sum of a subarray of size k, or calculating moving averages. Variable Size Window A variable-size sliding window can expand or contract based on certain conditions. This technique is often used when you need to find the optimal subarray that satisfies specific criteria. Common Applications:

New FileFix attack runs JScript while bypassing Windows MoTW alerts

A new FileFix attack allows executing malicious scripts while bypassing the Mark of the Web (MoTW) protection in Windows by exploiting how browsers handle saved HTML webpages. The technique, was devised by security researcher mr.d0x Last week, the researcher showed how the first FileFix method worked as an alternative to 'ClickFix' attacks by tricking users into pasting a disguised PowerShell command into the File Explorer address bar. The attack involves a phishing page to trick the victim in

Microsoft Offers Free Windows 10 Extended Security Updates, but There's a Catch

Microsoft is closing the door on Windows 10 in October 2025, and will be ceasing security support for that operating system unless users pay $30 for a one-year extended security update. On June 24, with less than four months on the clock until support expires, Microsoft has added a free option. Users need to turn on cloud backup and connect it to their OneDrive account. The ability to get free updates on Windows 10 is a pretty big deal because it is still the most widely used Windows OS, accoun

7 things every Linux beginner should know before downloading their first distro

How I easily added Mac-like multitouch gestures to my Linux machine

Jack Wallen/ZDNET Years ago, I attempted to configure multitouch gestures for Linux and found it next to impossible. Back then, it was all about configuring with a text file, and the options were cumbersome and confusing. Even with one of the first GUI apps that came along, the results were never promising. Fast-forward to now, and there's a simple-to-use app that makes adding and configuring multitouch gestures a breeze. That app is called Touché, and it makes customizing touchpad gestures v

Microsoft unveils Windows 11 25H2 - here's who can try it now and how

Lance Whitney / Elyse Betters Picaro / ZDNET Microsoft has rolled out the initial build of this year's annual update for Windows 11, known as 25H2.

Microsoft warns of Windows update delays due to wrong timestamp

Microsoft has confirmed a new known issue causing delivery delays for June 2025 Windows security updates due to an incorrect metadata timestamp. As Redmond explains in recent advisory updates, this bug affects Windows 10 and Windows 11 systems in environments with quality update deferral policies that enable admins to delay update installation on managed devices. While update deployment delays are an expected result when using such policies, the wrong timestamp for the June security updates wi

Many ransomware strains will abort if they detect a Russian keyboard installed (2021)

In a Twitter discussion last week on ransomware attacks, KrebsOnSecurity noted that virtually all ransomware strains have a built-in failsafe designed to cover the backsides of the malware purveyors: They simply will not install on a Microsoft Windows computer that already has one of many types of virtual keyboards installed — such as Russian or Ukrainian. So many readers had questions in response to the tweet that I thought it was worth a blog post exploring this one weird cyber defense trick.

Modelling API rate limits as diophantine inequalities

modelling API rate limits as diophantine inequalities You're allowed 10 requests per hour. Each task you run makes three attempts: initial call, retry after 10 minutes, and retry after 30 minutes. What’s the maximum number of tasks you can safely run per hour? Most engineers throw exponential backoff at the problem. And it works great in most cases! But can we, for the sake of having fun, be more mathematical about this? In a way, this is just an integer feasibility problem. the setup Let’

Microsoft says Windows 11 is 2x faster, except they used ancient PCs to benchmark Windows 10

Facepalm: Microsoft is once again aggressively pushing users to move from Windows 10 to Windows 11. This time, the Redmond firm is boasting that the newer OS is up to 2.3x faster than its predecessor – but fails to mention its deeply flawed testing methodology. Tech giants aren't renowned for their honesty and openness. When it comes to making claims and pointing to benchmarks, it's not just Nvidia that plays fast and loose with the truth.

Microsoft extends free Windows 10 security updates into 2026

Last fall, Microsoft announced that individuals who wanted to keep using Windows 10 past its official end-of-support date could do so by opting into the company's Extended Security Update (ESU) program at a cost of $30 per PC. That payment would get users a single year of additional security updates. Today, less than four months before that October 14, 2025, cutoff, Microsoft is announcing additional options for people who can't or don't want to pay that fee. Individuals who want to pay $30 for

So Long, Blue Screen of Death. Amazingly, You'll Be Missed

For decades, the Blue Screen of Death, or BSOD to its friends, has instilled a mix of panic, dread, exasperation, and rage across countless Windows users. But now, Microsoft is getting ready to retire it. According to a Microsoft blog post, the Windows 11 crash screen—or, as the company puts it, “unexpected restart screen”—will soon adopt a distinctly more minimalist vibe. Along with scrapping the blue (in favor of a perhaps even more dread-inducing black), the revamp also ditches the sad face

Microsoft changes Windows in attempt to prevent next CrowdStrike-style catastrophe

In the summer of 2024, corporate anti-malware provider CrowdStrike pushed a broken update to millions of PCs and servers running some version of Microsoft's Windows software, taking down systems that both companies and consumers relied on for air travel, payments, emergency services, and their morning coffee. It was a huge outage, and it caused days and weeks of pain as the world's permanently beleaguered IT workers brought systems back online, in some cases touching each affected PC individuall

The Windows kernel is about to receive a security-focused redesign after CrowdStrike crash

Why it matters: The kernel space is the core component of a computer operating system, where critical hardware management and device driver code reside in memory. If a kernel-level driver malfunctions, the entire OS can behave erratically – or simply crash and burn with a BSOD. Microsoft has stated that it is working on a significant change to the Windows architecture to help prevent another large-scale incident like the one involving CrowdStrike a year ago. Microsoft is developing a new securi
