If you use Windows, you have come across times where your YouTube videos start buffering, games lag out of nowhere, or file downloads slow to a crawl. You can try fixing the problem with a faster connection, but the real culprit here is Windows.
Now there aretools that'll clean, optimize, and boost your Windows PC instantly, but they may not help the bandwidth hog that Windows is. Thankfully, changing a simple setting can do the trick.
How Windows steals your bandwidth
Not all of your internet is reaching your apps
Windows 11 has this sneaky behavior where it will reserve a part of your available bandwidth for system tasks like updates, background app syncing, and something that Microsoft calls "Delivery Optimization". Ideally, this shouldn't affect your internet connection or any other tasks you carry out on your PC, but withWindows 11 still feeling like a work in progress years after launch, it rarely functions as it ideally should.

The problem only gets worse if you're downloading Windows updates, using the Microsoft Store, or if apps are syncing in the background. This not only affects your system, but can also slow down internet speeds for other devices on your network.
Windows reserving a certain part of your bandwidth for system tasks isn't necessarily a bad thing either. After all, it's important to keep your OS and apps updated and running smoothly. If every program on your PC competed equally for bandwidth, critical system functions might not get the priority they deserve.
That said, if you're working from home or running bandwidth-critical applications, having Windows silently consume your bandwidth without asking you can be frustrating. Sure, Windows and your apps are updated, but if you're struggling to watch a YouTube video, it's no good.
Metered connections to the rescue
Putting a meter on the connection gets Windows' internet usage down
The good thing is that Windows already has a solution tucked away in your network settings. Just like it automatically categorizes every network you connect to as public or private, it also marks them as metered or unmetered.

This secret Microsoft app claims to boost Windows performance — I tested it
This app isn’t magic, but it makes your PC feel like it tried.
This feature is intended to help Windows understand that you're on a connection with limited data, like when you're using your phone's hotspot or a capped internet connection. When enabled, Windows becomes much more conservative with how it uses bandwidth for background tasks, updates, app syncing, and everything else.
You canenable or disable metered connections for a Wi-Fi network on Windows 11 easily, and the same steps apply to Ethernet as well. To mark a connection as metered, follow these steps:
- Open the Windows Settings app by pressing theWindows Key + I keyboard shortcut.
- Click onNetwork & internet.
- Find your connection, whether it's Wi-FI or Ethernet, and click it to open its properties.
- Enable the toggle forMetered connection.
And that's it. Windows will now throttle its background activities significantly to save data. Do keep in mind that some apps might work differently to reduce data usage, but you'll rarely see any changes that affect your workflow.
Keep in mind that once you set a connection as metered, Windows will be more conservative with updates. Given how frequently Windows updates can break things, it's not necessarily a bad thing. You'll still get security patches, but you might need to manually trigger updates more often than usual. Depending on your relationship with Windows updates, this can either be an annoyance or a feature.
Advanced options for power users
More advanced ways of tuning Windows' bandwidth usage
If you're okay tinkering with system settings and have Windows 11 Pro, you can change a setting called theQoS Packet Scheduler. You'll find this option buried in the Network settings of theAdministrative Templates section in Windows' Group Policy Editor. It lets you adjust exactly how much bandwidth Windows reserves for system tasks.
The specific setting you're looking for under QoS Packet Scheduler is calledLimit Reservable Bandwidth. It's set up to 20% by default, but you can find a number that works for you by trial and error. You can also set it to 100% if you want Windows to only use available bandwidth after everything else is done.
The obvious catch here is that this setting is only accessible via the Group Policy Editor, which only works if you're running Windows 11 Pro or Enterprise. If you've got the Home edition, you're stuck with setting networks as metered connections.
Take your bandwidth back
Your internet shouldn't be spent serving Windows
I'm not saying that marking your connection as metered will solve all bandwidth issues on your PC. It won't make your connection any faster either. You'll still be limited by factors like overall network bandwidth, signal strength if you're on Wi-Fi, and network stability.
However, doing this can prevent Windows from being an invisible bandwidth hog. You'll get more consistent speeds and better performance for the programs you actually care about.
Windows 11 treating your bandwidth like it owns the connection is a real problem that can affect anyone without a fast enough internet connection. There's no guarantee that you'll always have access to a fast network when required. The good news is that the fix takes about 30 seconds and requires zero technical knowledge, so it doesn't hurt to try.
