How to disable Startup Boost on Microsoft Edge – and reclaim RAM on Windows 11

• Startup Boost in Microsoft Edge keeps processes running in the background to speed up launch times.
• This feature can consume hundreds of MB of RAM even when the browser is closed.
• Disabling Startup Boost reduces memory usage and improves system responsiveness.
• The trade-off is a slightly slower browser launch, but the impact is minimal.

On Windows 11, Microsoft Edge is designed to feel fast the moment you open it, and one of the features responsible for that experience is Startup Boost. By keeping background processes running even after you close the browser, Startup Boost reduces launch times and makes the browser feel more responsive. However, that convenience comes at a cost.

Startup Boost can quietly consume memory and system resources in the background, even when you are not actively using the browser. For devices with limited RAM or users who prefer a lean, optimized system, this behavior can lead to unnecessary resource usage, slower performance across apps, and reduced battery efficiency on laptops.

If you are trying to squeeze every bit of performance out of your system, disabling Startup Boost on Microsoft Edge is a simple but effective tweak. In this guide, you will learn how the feature works, why it may be affecting your computers’ performance, and how to turn it off to reclaim valuable system resources.

In this guide, I’ll outline the steps to free up system memory by disabling Startup Boost on Microsoft Edge for Windows 11.

Disable Startup Boost on Microsoft Edge

To turn off Startup Boost in Windows 11’s default browser, follow these steps:

1. Open Microsoft Edge on Windows 11.

2. Click the “Settings and more” (three dots) menu from the top-right.

3. Select the Settings option.

4. Click on “System and performance” from the left pane.

5. Click the System settings.

6. Turn off the Startup boost toggle switch.

   

7. Turn off the “Continue running background extensions and apps when Edge is closed” toggle switch.

8. Restart the computer.

Once you complete the steps, Microsoft Edge will no longer start background processes at startup, reducing system memory usage by hundreds of megabytes. The amount of RAM saving will be proportional af the total amount of memory installed on your computer.

When I tested this setting, it reduced memory usage by around 600 MB, but the savings will vary by device.

Yes, as a result of this change, the browser will take a bit longer to start, but the delay is marginal and won’t affect overall performance.

Pureinfotech’s Take

On Windows 11, disabling Startup Boost in Microsoft Edge is one of those small tweaks that delivers a surprisingly meaningful improvement in system efficiency. While the feature does what it promises by making the browser launch faster, it achieves this by keeping processes active in the background, which directly impacts memory usage even when the browser is closed.

For most modern systems with plenty of RAM, the trade-off may go unnoticed. However, on devices with limited memory or for users who prioritize performance and responsiveness across multiple apps, Startup Boost becomes more of a liability than a benefit. Background resource consumption adds up quickly, especially when combined with startup apps and other persistent services.

Turning off Startup Boost, along with background extensions, is a practical optimization that can free up hundreds of megabytes of RAM. The slight delay when launching the browser is negligible compared to the gains in overall system responsiveness, particularly on laptops or older hardware.

In short, if your goal is to keep Windows 11 running lean and efficient, this is a setting worth disabling.
