Windows 10 1709 - wsappx process high cpu load & and black screen after login for some users

I'll had an issue that wsappx takes all the cpu of one core (ill think its single threaded app).

Have searched the internet and dont found an solution.

just a few hints that a clean boot solved the issue for some but that didnt worked for me.

The issue also just poped up on some users of the machine, some users where fine.

But when the "defect" user has logged in into his account the wsappx goes crazy and dont come down, also when another user takes the local session.

Here are some thread about the issue: https://www.google.at/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&cad=rja&uact=8&ved=0ahUKEwiuvpPZ0cDYAhVSb1AKHcsxAtQQFghBMAM&url=https%3A%2F%2Fanswers.microsoft.com%2Fen-us%2Finsider%2Fforum%2Finsider\_wintp-insider\_perf-insiderplat\_pc%2Fwsappx-process-takes-more-cpu-usage%2F73393475-312c-4044-8c9e-a5f78f4d7c4c&usg=AOvVaw0uM47U4309VlEkdo0XGWzA

Another issue i have faced was that after logging in, some users facing black screen.

There was a mouse cursor and task manager could be lunched (with ctrl-alt-del) but nothing else showed.

Seemed that explorer stucked in loading.

After googling it turns out that "AppReadiness" (german: App-Vorbereitung) service caused that issue.

After disabling the service the users could logon again.

Here is a thread about the issue and with the workaround: https://h30434.www3.hp.com/t5/Desktop-Boot-and-Lockup/SOLVED-For-everyone-who-is-having-black-screen-after-login/td-p/6318990/page/2

Now i have found a solution for this which works for booth issues and solved them!

Just clear the two user accounts (Control Panel - User account - manage other user account).

You must be logged on from another, working user account.

This olved booth issue 100% for two other user accounts without any workaround.

Hope this helps someone with this bad issue!

    Hey Jon.

    I have searched across the web and did'nt found any other working solution.

    (That doesnt mean there is one :-)

    I'll know its a pain to recreate the user profile(s), but in my case i was lucky to have all my data on an server (network drive).

    The issue is gone for me since ill wrote the OP, so i'll assume it's a permanent fix.

    Sorry for not having a better solution,

    but if you find one, just let us know :-)

    I had the wsappx high CPU issue today and was able to fix it without deleting user accounts. What worked for me was to go into Settings-->Apps, then sort by date and reset all the recently updated Microsoft apps.  After doing this for maybe 6 different apps, the high CPU issue stopped immediately.

    I am speculating that the issue is due to some sort of cache corruption which the reset resolves.

    FWIW, I tried a bunch of other solutions suggested on the web without success. These included changing the pagefile settings, disabling the Microsoft Store with regedit (which did not even work to do that) or with Group Ploicy editor.

    I just set up new Win 10 1709 system and am having the same problem with the built in administrator account so deleting it isn't an option.  I did delete the administrator's profile but when I logged in again the same problem occurred. 

    Also, resetting all apps would be more work than a rebuild since they mostly all have today's install date.  I tried resetting just the MS Store app but it ran for 30 munutes and never seemed to finish.

    I created a local account called admin and put it in the administrators group and it works like it should.

    Anyone have another idea besides a rebuild or using the secondary admin account?

    We have been seeing this on all the new OEM December 1709 builds from Lenovo on desktops and laptops.

    If we see the problem, we are only left with Reset the PC.  There is no recovery that we can find that solves this permanently, even the stuff suggested above.

    1. We are just running "Reset the PC" the OS in the Recovery section of Settings, then
    2. Remove practically everything from Appx using PowerShell except for the few legit applications.

    For example:

    $Applist = Get-AppXProvisionedPackage -online

    $Applist2 = Get-AppxPackage 

    $Applist2 | WHere-Object {$_.name -like "*Lenovo*"} | Remove-AppxPackage 

    $Applist | WHere-Object {$_.packagename -like "*Lenovo*"} | Remove-AppxProvisionedPackage -online

    1. A GPO Registry setting:

    HKLM\SOFTWARE\Policies\Microsoft\Windows\CloudContent 

    DisableWindowsConsumerFeatures

    dword value 1

    1. Uninstall the Office 365 Home and Student.

    Before going down my route, I recommend you test and look stuff up first so you don't brick a computer.

    I am curious if anyone else has any other suggestions.

    Oh, and we are not seeing this with stock 1709.  And this is occuring whether or not the is a laptop, tablet, or desktop, on the domain or not on the domian, inside the corp firewall, or in the guest network.
