Microsoft Edge has come a long way, but it can still slow down or feel sluggish on Windows 10 or 11. This guide covers practical, up-to-date solutions to speed up Edge, from built-in settings to advanced tweaks. Whether you notice lag, long startup times, or pages loading slowly, these tips will help you get Edge running smoothly again.
Clear Cache, Cookies, and Browsing Data
Over time, Edge stores website data, images, and cookies to speed up future visits, but too much buildup can actually slow things down. Clearing this data is a quick fix for many performance problems. Click the three-dot menu in Edge, go to Settings > Privacy, search, and services, then find Clear browsing data. Choose Cached images and files and Cookies and other site data, then click Clear now. You don’t have to delete your browsing history unless you want to start fresh.
Do this regularly, especially if sites are loading slowly or you run into odd glitches. Just be aware that clearing cookies will sign you out of most websites, so have your passwords handy or saved in a password manager.
Disable or Remove Unnecessary Extensions
Extensions can be useful, but too many can hog memory and drag down performance. To check your installed extensions, go to the three-dot menu > Extensions. Review what’s active. Disable any you rarely use by toggling them off, or click Remove to delete them completely.
Some extensions, like ad blockers or heavy privacy tools, can consume more resources than you’d expect. If you notice a slowdown after installing a certain extension, try disabling it to see if Edge speeds up. Only keep extensions you need daily. Fewer extensions mean a lighter, faster browser.
Turn Off Unused Startup Boost and Background Apps
Edge’s Startup Boost lets the browser preload in the background so it opens faster. However, if your PC is low on resources or you rarely use Edge, this feature can actually slow things down overall. To adjust, go to Settings > System and performance. Find Startup boost and toggle it off if you don’t need Edge ready at a moment’s notice.
Also, scroll down to Continue running background extensions and apps when Microsoft Edge is closed. If this is on, Edge and some extensions keep running after you close it. Turn this setting off unless you rely on background activity, like notifications. Disabling these features can free up RAM and CPU, especially on older PCs.
Update Microsoft Edge and Windows
Running outdated versions of Edge or Windows can introduce bugs, security risks, and slowdowns. Edge updates itself, but it’s worth checking manually now and then. Open Edge, go to Settings > About Microsoft Edge. If an update is available, it will download and prompt you to relaunch the browser.
Windows updates also affect browser performance, since system libraries and graphics drivers can impact how Edge runs. On Windows 10, open Settings > Update & Security > Windows Update and check for updates. On Windows 11, go to Settings > Windows Update. Install all pending updates and restart your PC to apply changes.
Adjust Edge’s Performance Settings
Edge includes built-in performance features designed to keep the browser fast and efficient. Under Settings > System and performance, you'll find two key options: Optimize Performance and Efficiency mode. Efficiency mode reduces resource usage, which helps on laptops or if your PC is multitasking. You can set it to activate automatically when your device is unplugged, or always keep it on for maximum savings.
There’s also a Sleeping tabs feature. Edge will "sleep" inactive tabs after a set period, freeing up memory and CPU. Adjust the timeout under Optimize Performance. If you tend to work with lots of tabs, this makes a big difference in overall speed and battery life.
Tweak Site Permissions and Block Autoplay
Some websites load videos or animations automatically, which can slow down Edge, especially on older machines. To limit this, go to Settings > Cookies and site permissions. Look for Media autoplay and set it to Limit. This will prevent most videos from auto-playing, which improves load times and lowers CPU use.
You can also review permissions like location, camera, or notifications. Disable anything you don’t use. Not only does this speed up browsing, but it also improves privacy and reduces distractions. Every little reduction in background activity helps make Edge snappier.
Reset or Repair Microsoft Edge
If Edge still feels painfully slow after all these tweaks, it could be a corrupted browser profile or damaged files. There are two ways to fix this: repairing Edge or resetting it. On Windows 10 or 11, open Settings > Apps > Apps & features, find Microsoft Edge, click the three dots, and select Modify or Advanced options. Here, you’ll see options to Repair or Reset the browser. Repair keeps your data, while Reset will remove extensions and settings (your favorites and passwords stay intact, if they’re synced).
Most of the time, a repair fixes lingering performance issues without any data loss. Use reset as a last resort if nothing else works. Afterward, Edge should run almost like new.
Optimize Your System for Better Browsing
Sometimes Edge isn’t the entire problem. If your PC is low on RAM or running multiple heavy programs, any browser will feel slow. Consider closing unused apps, especially those that use lots of memory (like Photoshop or games). Open Task Manager (Ctrl + Shift + Esc) to check what’s hogging resources.
Disable unnecessary startup programs in Task Manager’s Startup tab. If you have under 8GB RAM, adding more can make a big difference for all browsers, including Edge. Running regular malware scans with Windows Security or another trusted tool can also help, since unwanted software can impact performance across your system.
Frequently asked questions
Why is Microsoft Edge so slow after an update?
Sometimes new updates introduce bugs or require more resources. Try clearing cache, disabling unused extensions, and checking for additional updates that may fix performance issues.
Does too many tabs make Edge slower?
Yes, each open tab uses memory and CPU. With dozens of tabs, Edge slows down, especially on low-end PCs. Use the sleeping tabs feature to manage resources better.
Should I switch to a different browser if Edge is slow?
Not necessarily. Most performance issues can be fixed with the steps above. If Edge stays slow after troubleshooting, you can try Chrome or Firefox, but the underlying problem may follow you.
Is it safe to reset or repair Microsoft Edge?
Yes, using Windows' built-in repair or reset options is safe. Repair keeps your data, while reset removes extensions and settings but keeps favorites and passwords if synced.
