Universal Plug and Play (UPnP) is a way for devices on a network to find each other and share stuff without needing you to do much. It makes connecting devices easy but can also open doors for security problems. In this guide, we’ll talk about why turning off UPnP can be a smart move, show you how to do it on Windows 11, and give you tips to make your network safer.

The risks of having UPnP enabled
UPnP makes life easier but it’s not always good news. Let’s dig into the main problems:
- UPnP doesn’t check who’s trying to connect, so any device can hop on and mess with your devices.
- It can open up pathways in your router all by itself, which might let hackers sneak in and steal your data.
- Since every device might do UPnP differently, there could be weak spots that hackers can use to break into your network.
- Internet of Things (IoT) devices love UPnP for easy setup, but their security isn’t always strong, making them easy targets.
Because of these issues, turning off UPnP can in a sense help keep your network and personal info safe.

Method 2: Using the Registry Editor
You can also turn off UPnP using the Registry Editor, but be careful because messing up the registry can cause serious problems. Always back up your registry first.
- Open the Registry Editor: Press Win + R, type regedit, and click OK. If asked, say Yes.
- Go to the SSDP Discovery Service key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SSDPSRV
- Change the Start value: Double-click Start, set it to 4 (Disabled), and hit OK.
- Go to the UPnP Device Host service key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\upnphost
- Change the Start value: Double-click Start, set it to 4, and click OK.
- Close the Registry Editor.
- Restart your PC.
By doing this, you’ll have turned off UPnP on your Windows 11 PC using the Registry Editor. But be careful with registry changes!
More ways to keep your network safe
Turning off UPnP on Windows 11 is a good start to protect your home network. But, there’s more you can do to make it even safer. Check out these tips:
- Make sure your router’s software is always the latest. This helps fix security weak spots.
- Change your router’s factory-set login info to something only you know. This keeps strangers out.
- If you can, turn on WPA3 encryption for your Wi-Fi. It’s the newest and most secure. If not, WPA2 is still good.
- Turn off the option to change your router settings over the internet. This stops hackers from messing with your network from far away.
- Use a really good Wi-Fi password. Make it something unique and tough to guess.
- Set up a separate Wi-Fi for guests. It keeps your main network safer.
- Don’t use Wi-Fi Protected Setup (WPS). It’s meant to make connecting devices easy, but it can also make it easy for hackers.
- Keep all your devices and drivers updated. This closes loopholes hackers might exploit.
- Adding a firewall to your network is like having a guard. It watches for trouble coming in or going out and stops it.
- Think about using a VPN. It scrambles your internet traffic, making it hard for hackers to spy on you.
What you might miss without UPnP
Before disabling UPnP, I think it’s important that you know what you might miss without UPnP. It’s pretty much about making things easier for you. UPnP helps your devices to find each other and communicate without any work from your end. This comes in super handy when you’re setting up things like printers, gaming consoles, and all those smart gadgets at home quickly. Without UPnP, you might end up having to manually input settings, which could be a bit more time-consuming.
However, having UPnP enabled means you might have certain security risks in your network. Though, most people actually neglect this and keep their UPnP on all the time. If you value your security more and you don’t actually use UPnP at all, you might want to just turn it off.
