[Windows update installing the new Edge browser] Update KB4559309 Makes Computer Unbearably Slow

Anonymous

Last night I updated my windows 10 pro using KB:4559309. Since then my computer performance has absolutely tanked. my startup time is probably triple, loading any window has a few second delay.

I attempted to uninstall the update however windows tells me that it is required and cannot be removed.

This update has essentially rendered my brand new computer useless.

Please help!

Hey there, everyone

I have spoken to Missy Quarry, from the Edge team, and they are investigating this problem. However, they really need more details submitted though the Feedback Hub on Windows 10. 

To submit feedback, please go to start > Feedback Hub. 

You will need to click onto report a problem. Then enter your feedback/problem you are having with Microsoft Edge. On the categories you will need to make sure you have the following drop down options selected in the image underneath:

The more detail you can submit, the better it will be for the Edge team to find out what is causing this issue. So the detail box that has the test comment, should detail everything you are experiencing. 

Hope this helps, 

Regards,

    Last night it did the sam thing on my new computer. But it is fine now. This update

    is so extensive, it actually duplicates the windows directory, making a "Windows.old" directory and a (presumably) new Windows directory. The update warns you that you will need to reboot your computer several times, and that is most certainly true. It took forever to install and set up, but I rebooted the computer three times in a row and after that it was not slow. Also I deleted the Windows.old directory.

    Did you try rebooting three times and scheduling a disk check on the last one?

    You can schedule a diskcheck on reboot with the command line. In windows power shell:

    chkdsk /x /f

    or for a really long intense read/write testing check

    chkdsk /x /f /r

    Hi Nathan,

    I did send feedback earlier today.

    I can't imagine what that update did to make my WiFi slower and causes "Poor Connection" in Skype during a video call which freezes the video/audio intermittently.  However, if I plug my ethernet cable into the router and laptop, the Skype calls are ok with no pauses.  Seems crazy, but I can pinpoint the exact date when this problem began and it was the same day that the Edge update Win 10 Ver 1903 was installed on my laptop.  I have called Microsoft 3 times and the last time they installed Win 10 Ver 2004, thinking that will solve the problem.  It did not.
