Is someone watching your PC webcam? Modern laptops come with webcam LEDs, privacy shutters, and even switches that physically disconnect the webcam to ensure you’re in control. Windows also offers a variety of useful settings, but these software options aren’t perfect.
This is complicated on Windows 11 and Windows 10 PCs because Windows software was designed to have deep access to the operating system. It’s not like on a modern Android phone or iPhone, where apps have to request access to your camera. No, applications on your system can usually start using your webcam whenever they want. That’s fine with reliable, high-performance software, but it’s a problem if your computer is infected with Remote Access Trojans (RATs) or other types of malware.
Modern Laptop Webcam Privacy Solutions
Modern laptops, especially business laptops and high-end consumer laptops, have built-in webcam privacy solutions:
- Webcam LEDs are common on most laptops with webcams. A physical LED light will appear on or near the webcam when activated. If the light is on and you’re not using the webcam, that’s a clue that something is going on.
- Privacy Shutters are also becoming more and more common. You physically slide a shutter in front of the webcam and the shutter stops it from recording.
- Physical Webcam Shutoff Switches also appear. You flip a physical switch somewhere on your laptop – perhaps on the side, near the power button or ports – and the laptop disconnects the webcam. It no longer appears as a device connected to Windows, and software on your PC can’t access it until you flip that switch and reconnect it.
If webcam privacy is important to you, be sure to buy a laptop that has a shutter that physically blocks the webcam or a switch that disconnects it. Some laptops have function keys that disable their webcam on the keyboard, but this is usually not the case. disconnect the webcam – they simply send a signal to the operating system to turn it off. Malware running on your PC could re-enable the webcam if you disable it this way.
Business laptops often have physical privacy shutters so no recording on your webcam is necessary.

How to see which apps have used your PC’s webcam
Both Windows 10 and 11 will tell you which apps have recently used your PC’s webcam.

Unfortunately, this convenience is not foolproof. Microsoft’s own documentation points out that some applications may not appear in this list. While this access log is nice to have, sophisticated malware running on your PC could certainly prevent it.
To find the list of applications that recently accessed your webcam:
- In Windows 11, open the Settings app and select “Privacy & Security” in the left pane. Scroll down and click “Camera” under App permissions. Scroll down again and click “Recent Activity” to see which apps have used your camera in the last seven days.
- In Windows 10, open the Settings app and select “Privacy”. Choose “Camera” under App permissions in the left pane. Look at the list of apps, especially the desktop apps at the bottom. Windows will tell you the date and time the last time each application accessed your webcam.
Windows provides many options for viewing and controlling access to the webcam. But they are not foolproof and malware can bypass them.

You may also see your web browser here. Websites can access your webcam, but only if you allow them: your web browser controls which sites have access. You can check which sites in your browser settings:
- In Google Chrome, click menu > Settings. Select “Privacy & Security,” click “Site Settings,” and click “Camera.” See the “Allowed to use your camera” list here: you can remove sites if you don’t want them to have access to your camera.
- In Microsoft Edge, click Menu > Settings. Select “Cookies & Site Permissions” and click “Camera” under All Permissions. Look at the list of sites in the “Allow” list: these are the sites that have access to your webcam.
- In Mozilla Firefox, click menu > Settings. Select “Privacy and Security”. Scroll down to the Permissions section and click “Settings” to the right of Camera. Here you will see a list of sites that have accessed your webcam.
Your web browser gives you full control over which websites have access to your PC’s camera.

How to see if your webcam is in use right now
Windows relies on the camera status light to light up to indicate that your camera is in use. For devices without a physical camera LED, Windows will display “Camera on” and “Camera off” messages on the screen.
You can enable these on-screen messages on any Windows PC with the “NoPhysicalCameraLED” registry hack, if you want.
Other ways to disable your PC’s webcam
While many modern laptops have great solutions for disabling your webcam (all those shutters and switches), some don’t. You still have options:
- Unplug your webcam: If you are using an external webcam, you can simply unplug its USB cable from your computer when you are not using it.
- Disable it in UEFI or BIOS: If your laptop has a built-in webcam that you don’t use, you can boot into its UEFI firmware settings screen – this is the modern replacement for the traditional BIOS settings screen. You can boot to this interface from the Windows Recovery menu. From there, you can usually find an option to turn off the webcam. It won’t work again until someone reboots to that screen and enables it again – it’s not practical if you use the webcam frequently, but it’s a nice privacy upgrade if you don’t. never do it.
- Record or cover your webcam: The traditional method of covering your laptop webcam with tape or another type of covering still works! This became even more famous when Mark Zuckerberg revealed that he was recording his webcam in 2016. Today, most of us are not billionaires, and Zuckerberg certainly faces privacy threats than most people don’t know. But even this low-tech solution works for him. (These days, I hope Zuckerberg has a modern laptop with a built-in webcam privacy cover or logout!)
By the way, you’ll also find options to disable your webcam in Settings > Privacy & Security > Camera in Windows 11 and Settings > Privacy > Camera in Windows 10. You can use these options if you want, but don’t rely on them. on them: as the interface itself states on Windows 11, “Some desktop applications may not appear on this page or be affected by these settings.”
As with the list of apps that have recently accessed your webcam, traditional Windows desktop apps could bypass this setting, even if you’ve turned off the microphone – and it’s likely that the most dangerous malicious apps are designed to do this. If you’re concerned about privacy, it’s best to cover or physically disconnect the webcam – or at least disable it at a low level in your system’s UEFI settings.
Wait, what about microphone privacy?
There’s a huge elephant in the room here – and it’s microphones. Laptops have built-in microphones. These microphones do not have status LEDs and there are no physical switches to turn them off.
Imagine a conference room full of laptops with excellent webcam privacy solutions: every laptop has the shutter closed. Malware running on any of these laptops could still be listening. Of course, this would require at least one of those laptops to be infected with malware – and malware on a laptop could capture all sorts of other sensitive information, from passwords and payment details to ‘to sensitive correspondence.
Yet, as PCWorld pointed out in 2019, laptop makers haven’t offered the kind of microphone privacy switches we see in smart speakers. Hopefully this will be a priority in the future.
For now, you might be able to boot into the UEFI firmware settings and disable your laptop’s built-in microphone from there if you’re worried. Or, you can just record on your microphone. When Mark Zuckerberg revealed that he was recording on his laptop’s webcam, he also revealed that he was recording on his laptop’s webcam. microphone hole too. Of course, you can also prevent many of these threats with good security practices. As long as your computer isn’t infected with malware, you don’t have to worry about someone eavesdropping on you.
Still, it’s usually worth being extra careful – especially if you are a billionaire like Mark Zuckerberg.
