If you use Microsoft Edge daily, you've probably noticed that the browser has been adding more and more options, assistants, and "smart" modules. Many of these Microsoft Edge features are enabled by default , and while they're theoretically designed to help you, in practice they can compromise your privacy, consume more resources than necessary, or cause strange behavior, such as Edge continuing to run in the background even after you've closed it.
The good news is that most of these features can be adjusted or disabled directly in the settings. Understanding what each one does, how it affects your security and your computer, and which options to disable in Edge is key to enjoying a faster, less intrusive browser without any unpleasant surprises with your personal or banking data.
Privacy in Microsoft Edge: what you absolutely must disable
One of the major weaknesses of any modern browser is all the information it collects about you in the background: browsing history, usage patterns, identifiers, telemetry… In the case of Edge, there are several features worth reviewing to regain some of your privacy without sacrificing basic daily convenience.
First, it's essential to take a look at the Privacy, Search, and Services section within your settings. This is where you manage the collection of diagnostic data, the handling of cookies, cross-site tracking, and other options related to protection against trackers and ads.
Many of these features are designed to "improve the product" or "offer a personalized experience ," but in plain language, they usually mean that the browser sends information to Microsoft servers about how you use Edge, which websites you visit , and what kind of content you consume. If you prefer your browsing to be as untrackable as possible, you should adjust several settings.
In addition to telemetry, it's also important to review how Edge handles forms, logins, and synchronization with your Microsoft account. While syncing bookmarks and passwords can be useful, other data, such as payment methods or certain sensitive information, is best kept out of the browser or, at least, not permanently stored.
Sending diagnostic and telemetry data to Microsoft
Edge enables by default an option that allows it to send diagnostic and usage data to Microsoft under the guise of improving the browser. This feature collects information about how you interact with tabs, what errors occur , what settings you use, and, in some cases, data related to your hardware and operating system.
For the average user, the real benefit of keeping this enabled is practically nil, while in terms of privacy it means granting permission for a fairly detailed profile of your browsing habits to be generated. It's perfectly possible to use Edge normally and reliably without constantly sending this data to Microsoft, so it's advisable to disable the optional diagnostic data setting.
The typical way to disable it is to go to Settings > Privacy, search, and services , and find the section dedicated to diagnostic data. From there, you can limit the data sent to the minimum necessary or, if possible, cut off any additional telemetry that isn't essential for the browser to function.
In professional or business environments, this deactivation is usually even more advisable, since sensitive corporate data is handled and any reduction in the flow of information to external services helps to reduce the exposure surface.
Third-party cookies and cross-site tracking
Third-party cookies are one of the main mechanisms used by advertising companies and numerous services to track you online. Unlike first-party cookies, which are used to keep you logged in or remember preferences on a specific website, third-party cookies can track your activity across multiple domains to create a profile for marketing purposes.
Edge has long included the option to block these third-party cookies. From a privacy standpoint, it's highly advisable to enable this blocking, as it drastically reduces the level of tracking you're exposed to and limits the appearance of highly targeted ads based on your online activity. In many cases, browsing will continue to function normally, except for a few very specific services that rely on third parties for login or to display embedded content.
To adjust this, you need to go back to Settings > Privacy, search and services > Cookies , and select the "Block third-party cookies" option. If you notice that a page that's important to you stops working properly, you can always add specific exceptions for that domain, instead of opting out of blocking them all.
Microsoft itself recommends, as a measure to reduce malicious pop-ups and suspicious behavior, combining third-party cookie blocking with other security features, such as tracking filters or the use of a good content blocker through extensions.
Managing payments and bank details in Edge
Another particularly sensitive area is payment information. Edge, like other browsers, can remember your credit or debit card details to automatically fill in the information when you shop online. This includes the card number, expiration date, and, in some cases, even the security code (CVV). While this may seem convenient at first glance, storing this data in the browser poses a clear risk.
If you share your computer with others, use an account without a password, or simply leave your Windows session open, anyone who accesses your browser could use that information to make purchases without your permission. Even if you protect your computer well, malware or a vulnerability could expose the data stored in Edge. Therefore, it's recommended that you disable payment autofill and delete any saved cards in your browser.
To check this, go to the Passwords and Autofill section or similar within Edge's settings. There you can see your saved payment methods and decide whether to delete them all, keep only a few, or completely disable the feature that reminds you of new cards when you make a purchase.
Similarly, many users are unaware that Edge may also attempt to store card security codes . This practice is even riskier from a security standpoint, since the CVV code is typically used as the final filter to authorize online purchases without requiring the physical presence of the card.
The general recommendation is to never allow the browser to save these codes. If you have ever accepted this option, you should carefully review the payment information stored in Edge and make sure that no such critical information is being saved without your full knowledge.
Blocking pop-ups and redirects
Edge includes a pop-up blocker designed to prevent websites from creating new windows or tabs without your permission. This system is enabled by default and is quite effective against typical pop-ups such as aggressive ads, fake virus alerts, purported prizes, or "miracle" downloads.
Not all pop-ups are malicious: some banks display account statements in a separate window, and certain web applications use pop-ups for authentication. But the problem is that many websites abuse this feature to display intrusive advertising or try to trick users with phishing tactics. Leaving your pop-up blocker enabled is usually a good idea, as it filters most unwanted pop-ups without preventing you from manually opening new tabs or windows when needed.
To check or adjust its status, go to Settings > Privacy, search, and services > Site permissions > All permissions > Pop-ups and redirects . There you should see the "Blocked (recommended)" option enabled. Only if a highly trusted page stops working due to the blocker would it be reasonable to add it to the exceptions list.
It's important to understand that Edge's ad blocker can't block everything. If certain websites display banners or ads embedded within the content that appear to be pop-ups, the system won't detect them because, technically, they aren't separate pop-ups. It also can't prevent a window from opening if you click a button or link that triggers the pop-up, since in that case, Edge assumes it's an intentional action by the user.
If, despite having the feature enabled, you continue to see annoying pop-ups, you should check your browser's status: make sure Edge is up to date, scan your computer with a reliable anti-malware tool , and, if necessary, try temporarily disabling extensions to see if any are forcing redirects or opening windows without your permission.
Video enhancement features and resource consumption
Among Edge's most striking features is an option to improve the quality of streaming videos, correcting the image or increasing the clarity of certain content. This function can be useful for those who consume a lot of multimedia content, but it doesn't come without a price: it uses additional CPU and GPU resources , and can make the browser feel sluggish, especially on less powerful computers.
If you don't spend a significant amount of time watching high-resolution series, movies, or videos in your browser, this automatic enhancement probably won't be worth the extra workload. Disabling it can help Edge run more smoothly, reduce heat buildup on your computer, and extend battery life on laptops.
This feature is usually managed under System and performance in Edge's settings, where you'll find an option related to video enhancement or multimedia optimizations. Disabling it doesn't affect the browser's ability to play content; it simply prevents additional background processing.
In environments where performance is critical, such as work laptops or older computers, it's a good idea to combine this deactivation with other measures, such as reducing the use of animations, limiting background tabs, or taking advantage of Edge's sleep tab options to freeze tabs that have been inactive for a while.
Edge running in the background and startup options
One of the most perplexing behaviors for many users is finding that, after closing all windows, Microsoft Edge continues to appear in the Task Manager, consuming CPU or memory. This can be due to several factors: extensions and applications that remain active, startup boost features, or browser services that continue running in the background.
Edge includes a setting called “Continue running extensions and apps in the background when Microsoft Edge is closed.” If this option is enabled, certain extensions, web services, or linked apps can continue running to respond to notifications, syncs, or scheduled tasks. Disabling it is usually the first step to ensure the browser closes completely when you exit it.
Another related feature is Startup Boost , which preloads certain parts of the browser when Windows starts so that Edge opens faster the first time. While this theoretically improves the perceived speed of opening Edge, it means that Edge processes remain active on the system even if you haven't opened any windows. If you prefer to save resources and have a cleaner Windows startup, it's also advisable to disable this feature.
If Edge continues to appear in the background despite having both options disabled, there may be an extension behaving erratically, or even an integration with other services (such as email clients or corporate tools) that is forcing the browser to remain active. In that case, it's advisable to review the installed extensions, disable them all, and then re-enable them one by one until you find the culprit.
Finally, it's also worth checking that you haven't configured Edge to start automatically with Windows, either from the operating system itself or from the startup task list. Combining all these checks should ensure that when you close the Edge windows, the browser actually stops running.
Optional features and “extras” that Microsoft will allow you to disable
In recent months, Edge has received a host of new features: a sidebar with quick access tools, integrations with Teams and Outlook, improvements related to Copilot, additional services, interface experiments, and more. All of this makes the browser increasingly complex, and many users prefer a lighter, more focused Edge to an environment overloaded with extras they rarely use.
In response to this situation, Microsoft is testing a new option in the Canary version that will allow users to disable certain "additional" or optional features in bulk. The idea is that you can disable several modules that you don't need for your daily work, so that Edge frees up resources and reduces the number of active processes and services.
The interesting thing about this approach is that these features don't disappear forever: they'll remain available, but if you want to use them again at any point, you'll need to download the corresponding component again. This allows the user to have a more efficient browser while still retaining the option to access advanced tools if needed in the future.
For now, no official details have been released regarding which specific features will be included in this group of optional functions. It's reasonable to assume they will be clearly identified in the settings so users know what they are missing out on by disabling them and what impact this might have on the user experience or integration with other Microsoft products.
This dynamic has not yet reached the stable version of Edge, but everything indicates that, when implemented, it will represent an important step towards a more modular browser, where each user can decide to what extent they want an Edge loaded with services or a much cleaner and more minimalist Edge.
Advanced controls, known errors, and policies in professional environments
Beyond the options visible in the settings, Edge includes a comprehensive policy system designed specifically for businesses and IT administrators . These policies allow you to enforce browser behavior in areas such as TLS security, local network access , compatibility with specific encryption methods, extension usage, and whether to open in Internet Explorer mode.
For example, recent versions have introduced significant changes to the handling of TLS 1.3 and features such as hybrid Kyber support, which has led to errors such as ERR_CONNECTION_ABORTED o ERR_SSL_PROTOCOL_ERROR on some specific HTTPS sites. To temporarily address these issues, directives such as PostQuantumKeyAgreementEnabled, which allow the feature to be disabled at the cost of reducing cryptographic security.
There have also been cases where the strict application of X.509 key usage extensions has led to errors such as ERR_SSL_KEY_USAGE_INCOMPATIBLE, solvable through the directive RSAKeyUsageForLocalAnchorsEnabled in certain versions. However, many of these solutions are temporary and become ineffective in later versions, forcing administrators to pay close attention to the release notes for each update.
Another relevant point in corporate environments is access to the local network from web pages with iframes from various sources, especially when combined with VPN solutions or proxies like Zscaler. Changes introduced in version 143, which enabled local network access by default, have required adjusting web applications and using directives like LocalNetworkAccessAllowedForUrls to mitigate unexpected behavior.
Edge's integration with services like OneDrive and SharePoint has also required specific adjustments. The OneDrive sync client, for example, now automatically configures certain permissions to ensure fast, offline access from the browser, adding entries to the local network access permissions section. Depending on whether the client is installed per machine or per user, the behavior and notifications for enabling these permissions may vary.
Furthermore, interface changes, such as the removal of entry points for reloading sites in Internet Explorer mode for consumer devices, or the automatic opening of the sidebar with context for Teams and Outlook links, have caused confusion for some users. These features can be disabled using policies like HubsSidebarEnabled or specific controls within the Copilot and Sidebar options, demonstrating the extent to which Edge has become a highly configurable, but also more complex, browser to manage.
In general, Microsoft documents these known issues, their workarounds, and the releases in which they are permanently fixed. For organizations that rely on Edge, it's important to follow these release notes, as sometimes the only immediate solution is to revert to a previous version , adjust group policies, or change internal flags until a stable fix is released.
With all of the above in mind, it's clear that Microsoft Edge is a very powerful browser, but also one packed with features that don't always add value for every user. Reviewing telemetry, blocking third-party cookies, not saving payment methods and security codes, keeping the pop-up blocker active, disabling video enhancements that slow down your computer, and controlling what runs in the background are simple steps that can transform Edge into a lighter, more secure tool, better suited to your actual browsing habits.
