[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,

    What a nightmare, thanks Microsoft!!

    My desktop was running fine one minute, using a 2nd monitor and a wireless mouse, checked into my home office one night to find that the update KB4559309 had installed itself and the pc is locked requiring login.

    I login and boom, right off the bat issues.

    The 2nd monitor has blank screen and won't come on, wireless mouse now inoperative, so resorted back to a wired mouse I keep just for these situations ( just as well )

    Haven't found any other issues as yet, but am sure there may be others.

    My guess is something to do with drivers / settings etc may have been changed. Currently trying to limp along with one screen and a wired mouse ( wires everywhere ) thanks Microsoft

    This update forcefully ran on a second PC of mine and is now giving me "the code execution cannot proceed because concrt140.dll was not found" when trying to open some of my software.
