    CNEventWindowClass issue after update to 1903 d3f19448-b5ad-494c-8c51-e32244a201a5?upload=true.jpg

    I am having the same issue with the infamous CNEventWindowClass in my notifications that started after I updated to the 1903 version, never had this issue until then. I also noticed that it was it in my registry to which I exported it out (Saved just in case) hoping it would solve the issue and I am still having the issue with the same constant notifications. I am still getting them but not as frequent.

    Running Windows 10 Home Ver. 1903 Build 18362.295. HP Notebook X0H91UA#ABA , AMD-64bit and AMD graphics. Below is copy of Registry where it originally was before I removed it. Previous version was 1809 before the update. Unfourtanetly I can not roll back it has been too long and I do not want to go back to original factory version (HP version) for recovery which the version was 1703 I think.

    1. If this is a bug how do I resolve this issue (if there is one by now)? 2. will it harm my system if left alone? 3. What exactly is a CNEventWindowClass and what is it for or purpose. Someone, somewhere in the Microsoft community should know this, please help.

    :)

  2. Local profile issue after upgrading to 1903


    Hi roblinb

    Not listed in the Known.

    Known issues for Windows 10 May 2019 Update version 1903


    As far as Wifi any chance it is Qualcom inside USB adapter, if Qualcom then yes known issue.


    I might create another user (Local) and when if try again see if this issue occurs on both users.

    Would also suggest you run the first 5 steps in this tutorial to see if you have any corruption with current build.

    Use DISM to Repair Windows 10 Image
