How to Enable or Disable Windows Update Delivery Optimization
Windows Update Delivery Optimization speeds up update downloads by letting your PC share update files with other computers on your network or the internet. This peer-to-peer (P2P) system reduces the load on Microsoft’s servers and can save your internet bandwidth, especially if you manage multiple Windows 10 or Windows 11 devices.
When enabled, your PC downloads parts of updates from other PCs and can also send those parts to others. This makes updates faster and more efficient, preventing every single device from pulling the same large files independently.
Disabling Delivery Optimization means your PC will only download updates directly from Microsoft’s servers. You gain complete control over your internet usage and stop your computer from acting as a source for update distribution.
Security and Privacy Implications
You might wonder if this is safe. Microsoft uses secure methods to ensure the files you receive are authentic. However, some users prefer to disable it to avoid any background data transfer. If you are worried about privacy, turning this off ensures your computer does not participate in the P2P network.
Bandwidth Throttling and Network Impact
Does Delivery Optimization use my bandwidth to upload updates to others? Yes, it can. If you have a slow internet plan, this might cause issues. You can limit how much bandwidth is used for uploads. Go to Settings > Windows Update > Advanced options > Delivery Optimization > Advanced options to set upload limits.
How to Check if Delivery Optimization is Active
You can see if it is working by opening Task Manager. Press Ctrl+Shift+Esc. Click the Performance tab and look at your Ethernet or Wi-Fi usage. If you see high activity while no apps are open, Delivery Optimization might be sharing files.
How to Change Settings in 🪟 Windows 11

How to Clear the Delivery Optimization Cache
If you have disk space issues, you can clear the cache. Go to Settings > System > Storage > Temporary files. Select Delivery Optimization Files and click Remove files.
Summary
Windows Update Delivery Optimization is a tool for faster updates using P2P technology. While efficient, it can impact your bandwidth. You can manage these settings in the Windows Settings app or via the Registry Editor. Always monitor your data usage if you have a limited internet plan.
Is Delivery Optimization safe for metered connections?
Yes, Windows is smart enough to detect metered connections. If you set your Wi-Fi or Ethernet connection as metered in Windows settings, Delivery Optimization will automatically pause background uploads and downloads to prevent you from exceeding your data limit.
