Optimize Your Internet: Stop Windows from Sharing Updates with Other PCs

Many Windows users are unaware that their computers may be sharing update files with other PCs around the globe. This process is known as Delivery Optimization, a feature enabled by Microsoft by default. While it aims to speed up Windows updates by allowing files to be shared among devices, it can significantly impact internet performance.

Understanding Delivery Optimization

Delivery Optimization allows Windows PCs to download update parts from other computers instead of solely relying on Microsoft’s servers. In exchange, these PCs upload the same update files to assist other users. While this may seem beneficial, it often leads to reduced internet speeds, particularly during bandwidth-intensive tasks like gaming or video streaming.

Why Delivery Optimization Can Be Problematic

• Bandwidth Usage: When your PC uploads files, it consumes precious upload bandwidth, which can result in lag during gaming and video calls.
• Disk Space Consumption: Delivery Optimization keeps a cache of update files on your hard drive, using up to 10-20 GB of space.
• Impact on Data Plans: Users on metered connections may find the feature counterproductive, given the potential for significant bandwidth usage.

Steps to Optimize Your Internet: Disable Delivery Optimization

If you wish to prevent your Windows PC from sharing updates with other devices, follow these steps:

1. Complete Disable Option

Go to Settings, then navigate to Windows Update followed by Advanced Options. In Delivery Optimization, switch off the toggle labeled “Allow downloads from other PCs.” This will force all updates to download directly from Microsoft without uploads.

2. Limiting to Local Network

If you prefer to keep Delivery Optimization enabled, you can limit it to just your local network. Keep the “Allow downloads from other PCs” setting active, and change the option below it to “Devices on my local network only.” This permits sharing among your computers without affecting internet bandwidth.

3. Adjusting Bandwidth Usage

You can also control how much bandwidth Delivery Optimization uses. Go to Advanced Options in the Delivery Optimization settings. Here, you can adjust the sliders to limit both download and upload speeds. A good practice is to set the upload limit to 5-10% of your internet speed to minimize interference with other online activities.

Should You Disable Delivery Optimization?

Consider disabling Delivery Optimization if you:

• Use a limited data plan.
• Experience slow internet speeds during gaming or video calls.
• Have limited disk space on your device.

For households with multiple Windows PCs, limiting updates to the local network is a great compromise, allowing machines to share updates without disrupting your internet connection. Alternatively, capping bandwidth usage can help maintain a balanced approach.
