I audited my Windows laptop on hotel Wi-Fi and was shocked by what it exposed

hotel Wi-Fi audit

I ran a security audit on my Windows laptop using hotel Wi-Fi. The results were alarming.

I’ve spent over 15 years working in enterprise IT. I know the risks of public networks. But even I wasn’t prepared for what my own Windows laptop security audit revealed when I connected to hotel Wi-Fi during a recent work trip.

Using a handful of free and built-in tools, I scanned my machine’s network activity, checked for open ports, and monitored data flows. Within minutes, I found apps sending unencrypted data, a DNS leak exposing my browsing history, and several services broadcasting my device name and OS version to anyone on the same network.

This isn’t scaremongering. It’s a real snapshot of what happens when an average Windows laptop meets an untrusted Wi-Fi hotspot. Here’s exactly what I found — and how you can protect yourself.

The tools I used for this hotel Wi-Fi audit

You don’t need expensive software to run a basic network audit. I used only free, widely available tools:

  • Wireshark — to capture and inspect network packets in real time.
  • Nmap — to scan for open ports on my own machine and nearby devices.
  • Windows Resource Monitor — to see which processes were making network connections.
  • DNSLeakTest.com — to check whether my DNS queries were leaking outside my VPN tunnel.

Each tool revealed a different layer of exposure. Together, they painted a troubling picture.

What the audit uncovered: plain text data, open ports, and DNS leaks

Apps sending data in plain text

Wireshark immediately flagged several applications transmitting data without encryption. My email client, for instance, was still using unencrypted SMTP for outgoing mail. A weather widget was pulling forecasts over HTTP, not HTTPS. Even a system update check sent my Windows version and device name in plain text.

On a hotel network, anyone with Wireshark and a bit of know-how can read that data. It’s not just embarrassing — it’s a credential theft risk.

Open ports I didn’t know about

Nmap found three open ports on my laptop: 135 (RPC), 139 (NetBIOS), and 445 (SMB). These are classic Windows networking ports, often left open by default. On a trusted home network, they’re useful for file sharing. On hotel Wi-Fi, they’re an open invitation.

An attacker on the same subnet could potentially exploit SMB vulnerabilities or enumerate user accounts through NetBIOS. I hadn’t disabled these services because I never thought about them.

DNS leak despite using a VPN

I was running a VPN during the test — or so I thought. The DNS leak test showed that some queries were still hitting my ISP’s DNS servers, not the VPN’s. That means my browsing history was visible to the hotel network and my internet provider, even with a VPN active.

Why? Because Windows has a feature called Smart Multi-Homed Name Resolution. It sends DNS queries over all available network interfaces by default. If your VPN doesn’t explicitly block this, leaks happen.

Why hotel Wi-Fi is uniquely dangerous for Windows laptops

Hotel networks are shared, often poorly segmented, and rarely monitored. Unlike a coffee shop, you’re connected for hours — sometimes overnight. That gives attackers plenty of time to scan, probe, and exploit.

Many hotels still use WPA2 encryption, which is vulnerable to KRACK attacks. Even WPA3 isn’t a silver bullet if the network’s guest portal is insecure. And because hotels often place all guests on the same flat subnet, your laptop is directly reachable from the room next door.

Combine that with default Windows settings that prioritize convenience over security, and you have a recipe for data exposure.

How to secure your Windows laptop on public Wi-Fi

After this audit, I made several changes. You should too, especially if you travel frequently.

  • Use a firewall to block all inbound connections. Windows Defender Firewall can block unsolicited traffic. Make sure the profile is set to “Public” when you connect to hotel Wi-Fi. This automatically disables file sharing and device discovery.
  • Disable SMB, NetBIOS, and RPC on public networks. Go to Control Panel > Network and Sharing Center > Advanced sharing settings and turn off network discovery and file and printer sharing. Then disable the SMB 1.0/CIFS feature in Windows Features.
  • Force all apps to use encrypted connections. Check your email client’s settings for SSL/TLS. Use a browser with HTTPS-only mode enabled (Firefox and Chrome both support it).
  • Fix DNS leaks. Configure your VPN to use its own DNS servers and disable Smart Multi-Homed Name Resolution. Most quality VPNs have a kill switch that blocks all traffic if the VPN drops.
  • Run a quick scan before connecting. Use Nmap to scan your own machine for open ports. If you see any you don’t recognize, investigate.

Final thoughts: don’t trust hotel Wi-Fi — audit it

I walked into that hotel room thinking I knew the risks. I walked out with a much longer to-do list. The truth is, most Windows laptops are configured for convenience, not security. And hotel Wi-Fi is one of the most hostile environments your machine will ever encounter.

A 10-minute audit can reveal exposures you never knew existed. Take it from someone who just ran one: ignorance isn’t bliss. It’s a data breach waiting to happen.

Retro, the anti-algorithm photo app for friends, just banked $21M

Retro photo-sharing app

Retro’s quiet $21M raise

The friend-focused photo-sharing app Retro has pulled in more than $21 million in Series A funding, according to an SEC filing spotted by Business Insider. The filing, dated August 19, sits under the startup’s legal name, Lone Palm Labs, and reveals the round actually closed back in December.

PitchBook now pegs the company’s valuation north of $100 million. Retro hasn’t commented publicly on the raise, and didn’t respond to a request for comment.

The money comes at a telling moment. Social media has become a firehose of creator content, algorithmically ranked and increasingly generated by AI. Retro’s pitch is almost contrarian: show photos to the people who actually know you.

Built by ex-Instagram engineers who saw the feed problem coming

Retro was founded by Nathan Sharp and Ryan Olson, two former Instagram product engineers. They watched the platform drift from a friend-sharing tool into a broadcast network dominated by influencers. Sharp told TechCrunch in December: “Something that has to be true and will be true is that people will still want to see more of their friends.”

His point cuts to the heart of the current social media malaise. The For You page is great for killing time, but it’s terrible for staying connected. Sharp again: “The photos and videos you take will need to find a place where they can reach the intended audience.”

Retro is that place. It strips away the algorithmic noise and puts the focus squarely on your inner circle.

From personal journal to shared photo space

Launched in 2023 as a personal photo journal, Retro has evolved. It now lets you privately share photos of your week with friends, create shared albums, view and share recaps, and even “rewind” to time-travel through old memories. The app has become a go-to for groups who want a shared visual history without the performance of posting to a public feed.

The growth numbers back up the concept. According to app intelligence provider Appfigures, Retro has been downloaded about 7 million times since launch. In-app spending has jumped more than 460% over the past 180 days — a sign that the people who do subscribe are sticking around and using it regularly.

No ads, just subscriptions

Retro’s business model is refreshingly simple: no advertising. Instead, the company offers in-app subscriptions that unlock features like video, GIF and sticker comments, more styles, unlimited history, and special app icons.

It’s a small subset of users who pay, but the company’s bet is that those who do are committed customers. The subscription model also aligns with the app’s ethos — your data and attention aren’t the product.

Who’s backing the anti-algorithm bet?

The investor list reads like a who’s who of tech and venture circles. Thrive Capital leads the round, joined by Figma CEO Dylan Field, Scribble Ventures, Box Group, Imaginary Ventures, Coalition, Conviction, Copper, Positive Sum, and a roster of angels.

The mix of strategic and financial backers suggests confidence in Retro’s vision. Field, who runs a design tool company, likely sees the value in a social app that prioritizes genuine connection over engagement metrics.

What Retro’s raise says about the future of social

The $21M round is more than just a milestone for one startup. It’s a signal that investors are betting on a future where social media returns to its roots — connecting real people with real friends. As AI-generated content floods mainstream platforms, the demand for authentic, private sharing spaces is only growing.

Retro isn’t trying to replace Instagram or TikTok. It’s carving out a niche for something more intimate. And with this fresh capital, the team plans to keep building features that make it easier to share moments with the people who matter most.

For anyone tired of doomscrolling through sponsored posts and AI slop, Retro’s photo-sharing app offers a quiet alternative. The question now is whether it can scale its niche appeal into something bigger. The early numbers suggest it’s on the right track.

5 Overlooked Pixel Apps I Added to My Home Screen Because I Kept Forgetting to Use Them

overlooked Pixel apps

Why Your Pixel Home Screen Deserves a Second Look

Google’s Pixel phones are stuffed with exclusive features. That’s not hyperbole—it’s practically the brand’s identity. But here’s the thing: many of those features are hiding in plain sight, tucked inside apps you’ve probably swiped past a hundred times.

I’m guilty of it too. I’d buy a Pixel, marvel at the camera, then completely forget about the software tricks that make the phone genuinely useful. So I did something about it. I moved five overlooked Pixel apps to my home screen. Now I actually use them.

1. Recorder: The App That Transcribes Everything

You know that feeling when you’re in a meeting or lecture, and you desperately wish you had a transcript? The Pixel Recorder app does exactly that—and it’s been on Pixels since the Pixel 4.

It’s not just a voice recorder. It transcribes audio in real time, even when you’re offline. You can search for specific words in a recording, which is a lifesaver when you’re trying to find that one action item from a two-hour call.

I added it to my home screen because I kept forgetting I had it. Now, whenever I’m about to take notes on a conversation, I just hit record instead. The transcription is shockingly accurate, and it’s one of the most underrated Google Pixel features.

2. Now Playing: Your Personal Shazam, Always On

Every Pixel has a feature called Now Playing. It listens in the background and identifies music playing around you—no app needed. The catch? It’s buried in the settings, and most people never turn it on.

Here’s what I did: I added the Now Playing history shortcut to my home screen. It’s a widget that shows a list of every song the phone has recognized recently. Tap a song, and it opens in YouTube Music or your streaming app of choice.

Why does this matter? Because you won’t have to pull out your phone and open Shazam every time you hear a tune you like. The Pixel does it silently, and you just check the history later. It’s one of the best Pixel exclusive apps you’re not using.

3. Digital Wellbeing: More Than Just a Timer

Digital Wellbeing sounds like a guilt-trip app, but it’s actually a goldmine of hidden tools. The app tracks your screen time, sure, but it also has a Focus mode that silences distracting apps when you need to concentrate.

What really sold me, though, is the Wind Down feature. It shifts your screen to grayscale at a set time, which makes doomscrolling feel less appealing. I put a shortcut to Digital Wellbeing on my home screen because I kept forgetting to set it up properly.

Now I use it every evening. It’s a small nudge, but it’s genuinely changed how I wind down. If you’re looking for Pixel productivity tips, this is a good place to start.

4. Files by Google: The Cleanup Tool You Actually Need

Files by Google isn’t exclusive to Pixel, but it comes pre-installed and is deeply integrated. It’s not just a file manager—it has a smart cleanup feature that suggests old photos, memes, and unused APKs to delete.

I used to ignore it because I thought it was just a boring file browser. Then I checked the “Clean” tab one day. It found 2 GB of junk I didn’t know existed. That was the moment I moved it to my home screen.

The app also lets you share files offline with nearby devices, which is handy when you’re in a dead zone. If you’re tired of “storage full” notifications, this is the overlooked Pixel app you need.

5. Google Lens: The Visual Search Powerhouse

Google Lens is technically part of the Google app, but it deserves its own spot on your home screen. It’s a visual search tool that can identify plants, translate text in real time, and even solve math problems by pointing your camera at them.

I kept forgetting it existed because it’s hidden behind a few taps in the Google app. So I added the Lens shortcut directly to my home screen. Now, when I’m at a museum and want to know more about a painting, or when I’m trying to read a menu in another language, it’s one tap away.

It’s one of the most versatile hidden Google Pixel features, and it’s free. No reason not to use it.

How to Add These Apps to Your Home Screen

Adding any of these to your home screen takes about ten seconds. Here’s how:

  • Open your app drawer and find the app you want.
  • Press and hold the icon.
  • Drag it to your home screen.
  • For widgets like Now Playing, press and hold an empty spot on your home screen, tap “Widgets,” and search for the app.

That’s it. You’ll actually see them every time you unlock your phone, which is the whole point.

Don’t Let These Features Collect Dust

Pixels are packed with Google Pixel tips and tricks, but they only help if you remember they exist. Moving these five overlooked Pixel apps to my home screen was a small change that made a big difference in how I use my phone.

Try it. You might be surprised at how often you reach for them.

Windows 11 August 2026 update

Imagine clicking an app icon and watching it spring to life instantly—no spinning cursor, no gray freeze, just pure speed. That’s exactly what Microsoft’s latest Windows 11 update promises, and after testing it myself, I can confirm: the difference is real. The August 2026 patch, KB5121003 (build 26200.9168), takes the CPU boost feature that previously only sped up the Start menu and search and extends it to your actual applications. The result? Apps open noticeably faster, and that annoying gray screen freeze after idle or boot is gone. Here’s what’s happening under the hood, why your CPU isn’t in danger, and why Microsoft probably should’ve done this years ago.
