How to fix Microsoft Edge high memory usage in Windows?

Issue: Hello. I noticed that Microsoft Edge takes a long time to load websites and found that it uses almost all the available memory on my Windows PC. What should I do?

Solved Answer

Excessive memory usage by Microsoft Edge in Windows is a common problem that many users have expressed concern over. The issue appears when users notice slower system performance and long loading times. System performance may be impacted by this high memory use, which could result in delayed multitasking, slower response times, and a worse user experience overall.

It can be observed by users that Microsoft Edge keeps using up a significant amount of RAM on their machines, which can be problematic for those with low-end hardware. Even when the browser is not being used actively, the problem may still exist, indicating that there may be a problem with an extension or background process.

High memory use affects more than just a slow browsing experience. It may impact the operating system's general stability, with extreme cases possibly leading to crashes, freezes, or unresponsiveness. Users may notice that Microsoft Edge is using up all of their system resources, which makes it difficult to run other applications simultaneously and reduces overall productivity.

Even though Microsoft Edge is promoted as a browser that offers a seamless and efficient browsing experience, users are searching for solutions to enhance their system's performance due to the high memory usage problem. Potential remedies include adjusting the browser's settings, disabling unnecessary extensions, and making sure the most recent patches and updates are installed. Keep in mind that not every one of these solutions will be equally helpful. You may need to test out a few of them before finding which one best suits your particular circumstances.
