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!

    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.

    I'm not sure whether Dell is to blame, or Microsoft, or whether they got together and decided to start doing things the most inefficient way possible to save $0.10 but man, they made registering OEM Office a chore by no longer including any sort of record of the license key for office. You're supposed to just launch office, sign into your live account, and pray it registers correctly and that it installs a desktop app and generates a key on your live account rather than install as a windows store app and not generate a license key on your live account. Seems to go 50/50 between these two outcomes.

    This is probably how you end up with two of every office app in the start menu, and for all we know this is how wsappx goes haywire like this.
