Steps to reproduce

I left my computer over night and Microsoft Edge decided to fill up my whole memory. When I closed the tab, the memory leak was gone.

  • Hello,

    Unfortunately, we are unable to reproduce this problem in Edge without more diagnostic information. For in-depth responsiveness diagnosis, we need "repro cabs".  Those are automatically collected when you click the ‘Start capture’ link in the Feedback Hub and then repro the problem. Please reopen this case when you can attach the results. Thank you so much for your assistance with this issue.

    Best Wishes,
    The MS Edge Team

  • Unfortunately the memory leak bug is still present and since I use Egde my laptop became obsolete. I only use Edge.

    If you want to reproduce the problem. Geat a 8GB ram, deactivate hdd caching, surf at Facebook, Youtube or open many labels at Amazon and Ebay, and wait for a couple of hours.
    I’ve never seen this problem in older browsers

  • Hi same problem with me! Since a couple of weeks, memory, 8GB is in 2 hours gone. I get a message to stop the EDGE processes. If I do nothing the system turns to black.

  • Looks that with a registry hack the problem is gone.
    I Used Top 1 fix.

  • The registry hack posted before is not the solution.

    Last days I was wondering why the memory leak was not reproducible by MS Edge Team while surfing on the web… And suddenly I say dynamic content of the web and I though…

    If the content of the web changes dynamically and the "page prediction is ON", then Edge is continuously loading content and filling memory. So if page prediction is programmed wrong, when dynamic content changes, the garbage colector does not flush or frees the memory allocated before…

    So in Edge:

    Go to “settings and more” -> “advanced settings” -> and set to off “use page prediction to speed up browsing”

    Problem gone.
    Good Luck.

  • Hio Jose,

    Thnx for your reply!

    But what is the registry setting doing?
    Is there a disadvantage with changing the setting to 1?


  • There is no disadvantage but it’s not related with the trouble commented at the begining of this post. If you read the step 3 at the link you posted.

    “Step 3. Find ClearPageFileAtShutDown and change its value to 1.”

    Changing the value to 1 only deletes pagefile at shutdown, nothing to do with Edge’s RAM memory leakage commented on this section.

    I’m running Edge without memory problems since I disabled page prediction. It still uses lots of RAM memory and has lots of instances but it doesn’t give a problem.


  • Ok, thnx!

    I now have both settings enabled, so registry change and page prediction off. No problems anymore!

  • I’ll try both Jose and Rob. The settings change seems to work so far and I’ll change the registry setting next and let you know in a day or so. Thanks!

  • I have exactly the same problem with the memory usage climbing in Microsoft Edge. This then also pushes disk usage to 100% and my machine becomes unusable
