Instructions

1

Click the "Start" button, then enter "Dcomcnfg" into the search box and press "Enter." Wait while Windows configures and launches the Microsoft Management Console (MMC) Component Services Snap-in application.

2

Double-click the "Component Services" link in the left side of the MMC window.
Double-click the links underneath to navigate to "Computers" > "My Computer" > "DCOM Config" > "Microsoft Windows Remote Shell Host."

3

Right-click on "Microsoft Windows Remote Shell Host," then click "Properties" when the pop-up menu appears.
Wait for the "Properties" window to display, then click the "Security" tab in the "Launch and Activation Permissions" area.

4

Click "Customize" and then the "Edit" button.
In the "Edit" window, assign the following permissions:
"Everyone -- Local Launch and Local Activation"

"Network Service, System, Administrators Group, Interactive--Local Launch, Remote Launch, Local Activation and Remote Activation" (enable all of the checkboxes)

Close the MMC snap-in utility.

The following finally fixed all issues for me (Store and all apps broken with black X, can't access PC Settings):
1) Fixing the app store:
1. Open registry editor typing regedit.exe from a command line.
2. Browse to the registry key at HKEY_CURRENT_USER\Software\Classes\Local Settings\software\microsoft\windows\currentversion\appmodel\repository\packages.
3. Right click on the “packages” key and bring up the “Permissions” tab.
4. Click the “Advanced” button located at the bottom right corner.
5. Check to see the account name that shows up as the “Owner” (this is the first line of text on the “advanced security settings” dialog for the “packages” key).
It should say “SYSTEM”. (For me this showed the built-in local Administrators group)
6. If it is any other account, click on the “Change” button next to it.
7. Type SYSTEM in the “select user” dialog.
If “Multiple Names Found” window comes up, select the row for “SYSTEM”.
8. Click OK to the dialogs and close them all.
9. Run from admin command prompt: Powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml
2) Fixing all modern apps:
Run from admin PowerShell:
((Get-ChildItem "HKLM:SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\InboxApplications") | Get-ItemProperty).Path | Add-AppxPackage -Register -DisableDevelopmentMode
* When I ran this the black X persisted until after the next step and reboot. But trying to start an app gives me a new message and a link to the store.
3) Fixing 3rd party apps:
Delete the regkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Appx\AppxAllUserStore\[UserSid]
4) Restart. After a reboot the apps still showed the black X for a minute or so, but it soon cleared up on its own and all apps seemed to be working again. I was also able to update the apps from the app
store once signing in with a Microsoft account. Finally, I am again able to get into PC Settings.

This particular error can easily be resolved with a few simple steps. However, if you are not confident in your ability to use the methods below or they do not fully remove the issue on your computer, you may want to seek the assistance of a qualified repair technician who is well versed in fixing all windows store apps not working.

Back-up the Registry of your operating system.
Find the Registry Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade]
Note: this Registry Key should already exist, if it does not exist, create it.
Create a brand new DWORD Value that is named AllowOsUpdate
Set the Value to 0x00000001.
Close and reopen your Control Panel.
Restart the Microsoft Windows.
