ZDNET key takeaways

  • There are networks out there you should not connect to.
  • You could even mistakenly connect to a fake cell tower.
  • Android 17 has a feature that alerts you, so you can stay safe.

When you’re on the go, there may be times when you absolutely have to connect to a network. Maybe you’re in a location where cellular speeds are too slow to transfer a file, or maybe you’re simply concerned about something gobbling up too much of your data plan.

Regardless of the why, the important thing here is this: What network are you connecting to?

Are you connecting to a network at your favorite coffee shop (the one that isn’t protected by a password)? Maybe you’re shopping, and the store you’re currently perusing has a Wi-Fi network. Your gym? A hotel? The list of networks you should not randomly connect to goes on and on.

But what if you’re not sure about the security level of a network? Do you just automatically default to “I won’t connect to that network”? That’s the safest bet, but not always the most practical.

Fortunately, Android 17 can help you out because there’s a new addition to network security that can help protect you. Along with the Identity Check and Advanced Protection features added in Android 16, this new feature should help lock down your device.

This feature is called “Network notifications.” According to the settings option, you’ll get notified when your device connects to an unencrypted network or when a network records your unique device or SIM ID.

That’s important because you may not know if you’ve connected to an encrypted network. Don’t be fooled. Just because you have to enter a password to join a network doesn’t mean it’s encrypted. A malicious actor could set up a Wi-Fi network, make it seem like it belongs to your favorite coffee shop, keep it open (no password), and wait for you to connect. If that malicious actor sets that network up as unencrypted, they can easily read your data.

And that, my friends, is why it’s important for you to enable Android’s new feature. Because Android is smarter than we are at detecting if a network is unencrypted, this feature is a no-brainer. It’s also very easy to use. I’ll demonstrate on my trusty Pixel 9 Pro.

How to know when you’ve connected to a bad network

Now that you know the “why,” let’s talk about the “how.”

You might think this would be a challenging task, but it’s far easier than you think. All you have to do is tap an on/off slider and, boom, your Android phone will inform you if your phone or tablet connects to an unencrypted (aka “bad”) network. Here’s how.

The Network generation option should be enabled and grayed out. If it’s disabled and you can enable it, do so immediately.

You’ll also notice there’s an entry labeled “Network generation” that is permanently enabled. This option prevents you from connecting your device to a 2G network, which is often used to spoof cell towers using 3G/2G IMSI catchers. If you were to connect to an IMSI catcher, it could be used for intercepting your mobile phone traffic and tracking you.

Also: Your Android phone just got a powerful anti-theft upgrade. Here’s what’s new

This is a very simple thing that every Android user should enable (if it’s available). If you don’t find the “Network notifications” section in the location as directed above, search for it in your Settings app. If it’s not there, make sure to check and see if the version of Android on your device can be upgraded.

Microsoft has spent the last several years pushing Copilot and new user interface designs, which has meant that several great features included with Windows don’t get the recognition that they deserve. These are some of my favorites that will run on any Windows 11-compatible PC.

Clipboard history remembers everything you copy

Win+V replaces one of the oldest frustrations in computing

Windows’s default clipboard has been a source of minor but constant annoyance: it holds exactly one thing. If you copy something new, the previous item is wiped out. It is enough of a problem that multiple third-party apps were created to address the shortcoming.

Now, Windows has Clipboard History built in, though it isn’t enabled by default. To turn it on, press Windows+i, then navigate to System > Clipboard, and click the toggle next to Clipboard history.

Once it is enabled, you can press Win+V to view up to 25 items in your clipboard history, including text, images, and links.

If you have specific pieces of information you use daily—like an email signature, a common code snippet, or a home address—you should pin up some of those items. Pinned items persist between system reboots and clipboard history clears, which means you never have to hunt to find something when you need it.

You can even enable sync in the Clipboard settings, allowing your copied text to follow you between different PCs signed in to the same Microsoft account. Once you get into the habit of using Win+V, the standard copy-paste function will feel useless by comparison.

Voice typing actually works now

Win+H lets you write with your voice

Windows dictation software has a reputation for being clunky and difficult to use, but that isn’t the case anymore. Thanks to the improvements in AI that we’ve seen since 2024, voice typing accuracy has improved significantly, especially for technical vocabulary. You don’t have to spend your time manually fixing formatting either. The tool supports punctuation commands like “period,” “new line,” and “question mark,” which prevents your text from turning into a rambling mess.

To use voice typing, press Windows+H anywhere there is a text field.

While it isn’t a full replacement for high-end professional software, it is free, built-in, and more than good enough for long-form writing, taking down a sudden idea, or writing quick messages when your hands are full.

Snap layouts make window management effortless

Hover over the maximize button and pick a layout

You can manually drag windows to the edges of your screen to split your display up, but you’re doing more work than is necessary in most cases. Windows’ Snap Layouts allow you to instantly arrange your Windows into predefined halves, thirds, or quarters. Just hover over the maximize button on any window or press Win+Z.

One of the most practical aspects of this system is the Snap Group. If you snap a browser and a document side-by-side, Windows remembers them as a pair. When you Alt+Tab, you can bring the entire group back together.

Live captions transcribe any audio on your device

Real-time subtitles for anything you’re watching

You can enable real-time subtitles for any audio playing through your speakers by going to Settings > Accessibility > Captions, or by pressing Win+Ctrl+L. The audio is processed locally on your device; nothing is sent to the cloud, which is critical if you’re privacy conscious or if whatever you’re captioning demands confidentiality.

I’ve mostly taken to using it when it is too hot to wear my headphones. I can just toggle it on and keep watching without disrupting anyone around me.

There are some hardware requirements you need to meet. Basic same-language captioning works on any Windows 11 PC running 22H2 and up, but if you want real-time translation, you will need Copilot+ hardware with an NPU and at least Windows 11 24H2.

Dynamic Lock locks your PC when you walk away

Pair your phone via Bluetooth and your computer can lock itself automatically

I can’t count how many times I’ve stepped away from my PC only to think, “Dang, I forgot to lock my PC.”

Fortunately, Windows has an easy way to handle that automatically by pairing your phone with your PC. When your phone gets out of range (about 20 feet in my house, though your wall materials and layout will affect that), your computer will automatically lock after about 30 seconds. There is no need to install a separate app on your phone, the setup just uses the Bluetooth connection itself. While the 30-second delay means it isn’t a guarantee no one can access my PC, it does mean it won’t remain unlocked if I step away for a long time.

I especially like this feature when I’m working on my laptop in public.

You can enable Dynamic Lock by navigating to Settings > Bluetooth & devices and pairing your phone, then enabling Dynamic Lock in Settings > Accounts > Sign-in options.


Microsoft includes tons of great tools if you dig for them

These tools aren’t alone either. There are tons of practical tools buried in Windows, unappreciated and underutilized.

Each of these tools takes less than a minute to enable, but they can make a significant difference in your day-to-day workflow. It is worth the small investment of time to find them and set them up.

If you’re looking for even more advanced customization options, I’d recommend checking out Microsoft PowerToys. It gives you a huge range of fantastic tools that make Windows much more pleasant to use.
