windows presentation foundation host has stopped working

FIX: You cannot start an XAML Browser Application that is created by using Windows Presentation Foundation in the .NET Framework 3.0 or in the .NET Framework 3.5

You cannot start an XAML Browser Application (XBAP) that was created by using Windows Presentation Foundation (WPF) in the Microsoft .NET Framework 3.0 or in the Microsoft .NET Framework 3.5. Additionally, if you browse the XBAP in compatible browsers, you may experience one of the following symptoms:

A blank browser window may appear. Additionally, a download dialog box appears that never stops downloading.

You receive the following error message in the browser:

Deployment Failed

You receive an error message that states that the application crashed.

The PresentationHost.exe process and the browser may restart repeatedly.

Note Compatible browsers are browsers that support XBAP.

This problem occurs because of an abnormal condition that is caused in certain account migration scenarios or operating system upgrade scenarios.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756 How to back up and restore the registry in WindowsManually repair the permission settings. To do this, follow these steps:

Click Start , click Run , type regedit, and then click OK .

Expand HKEY_CURRENT_USER , and then expand Software .

Right-click Classes , and then click Permissions .

Under Group or user names , click the affected user account name.

Under Permissions for UserName , click to select the Allow check box for the Full Control permission.

Click Advanced , and then click to select the Include inheritable permissions from this object's parent check box.

Click Apply , and then click OK two times. Note If you still cannot start the XBAP, go to step 8.

Expand HKEY_CLASSES_ROOT , and then expand Interface .

Right-click {79EAC9C9-BAF9-11CE-8C82-00AA004BA90B} , and then click Permissions .

Under Permissions for UserName , click to select the Allow check box for the Read permission.

Click Apply , and then click OK . Note If you still cannot start the XBAP, repeat steps 6-7. If the problem is not resolved, follow steps 9-12 for the following registry keys:

{79EAC9C1-BAF9-11CE-8C82-00AA004BA90B}

{79EAC9C4-BAF9-11CE-8C82-00AA004BA90B}

If the problem is not resolved, go to step 13.

In Windows Explorer, locate the following path:

C:\Documents and Settings\ UserName \Local Settings\

Determine whether the following folders under this path contain a file that is named Desktop.ini:

The Application Data folder and its Deployment subfolder

The Apps folder

The Temp folder

Rename the Desktop.ini file to another name.

Locate the folder that contains the Desktop.ini file, right-click the folder, and then click Properties .

On the Security tab, click Advanced .

Click to select the Include inheritable permissions from this object's parent check box.

Click Apply , and then click OK . Note If the problem is not resolved, repeat steps 14-19 for all folders that are listed.

More Information

The PresentationHost.exe process runs with a restricted process token. The process gives up membership in the Administrators security group and in the Power Users security group. The applications that run in the Internet zone sandbox do not have to have the full permission to these security groups. Additionally, the process gives up many Microsoft Windows NT security permissions. This behavior is a defense-in-depth security feature. The effect of this feature resembles how non-elevated processes run on Windows Vista when User Account Control is active. In some account migration scenarios or operating system upgrade scenarios, subtle corruption of Access Control Lists (ACLs) may occur. This corruption causes a particular user account not to be explicitly given access to certain folders or registry keys that belong to the user profile. This problem may occur because permission inheritance on the parent object is disabled. This problem only affects the applications that have the group membership disabled. For example, the PresentationHost.exe application has the group membership disabled. This problem is known to affect the permissions for the following registry keys or folders:

The Classes registry key

The IPersistMoniker interface registry keys

Some folders in the following path:

C:\Documents and Settings\ UserName \Local SettingsFor example, the Application Data folder and its Deployment subfolder, the Apps folder, and the Temp folder are affected.

Task 1: Create a New Windows Presentation Foundation Application

• 13 contributors

In this task, you will create an empty Windows Presentation Foundation (WPF) application by using the WPF Application Visual Studio template and add references to the appropriate .NET Framework 4.6.1 workflow assemblies.

To create the WPF Application project

Open Visual Studio and on the File menu, point to New , and then click Project .

In the New Project dialog box, select either Visual C# or Visual Basic from the Installed Templates pane on the left side of the box. If the language of your choice does not appear, look under Other Languages .

Select Windows in the Installed Templates pane.

In the top pane, confirm that (the default value) .NET Framework 4 has been selected in the drop-down list box, and then select WPF Application .

Set the name of the project to HostingApplication at the bottom of the window.

Set the solution name to RehostingTheDesigner .

Click OK to create the application project. Visual Studio creates a basic WPF UI for your application and includes the appropriate XAML and code-behind files.

Add references to WorkflowModel assemblies. To do this, in Solution Explorer , right-click the HostingApplication project and select Add Reference .

In the Add Reference dialog box, click the .NET tab, hold down the CTRL key, select the following assemblies, and then click OK :

• System.Activities
• System.Activities.Presentation
• System.Activities.Core.Presentation

Windows Driver Foundation - User-mode Driver Framework Host Process Stopped Working

I am seeing this error pop up repeatedly "Windows Driver Foundation - User-mode Driver Framework Host Process - Stopped Working ".

I have updated Windows 10 (Home version 20H2 Build:19042.906). I ran the hardware diagnostic in the BIOS and the system passed. My drivers (Dell XPS15 9570) are up to date. I also ran the "sfc /scannow" and "DISM /Online /Cleanup-Image /Restore-Health" commands and it did not solve the issue.

The error description looks like the following:

Thanks for your feedback.

Igor, 

Thanks for your help and your suggestions. I updated every driver and tried to isolate the problem by removing devices one at a time. It did not work. The problem continued to occur. The problem occurs with all the devices removed. This tells me that the problem is not within the peripherals. Hmmm. I am not sure what else to try. 

I left the PC running all night standalone, with no peripherals attached and the error is changed. Now I see "WUDFHOST.exe - stopped working" with the following details:

Description

Faulting application name: WUDFHost.exe, version: 10.0.19041.1, time stamp: 0xe092f869

Faulting module name: usbinterface.dll, version: 0.0.0.0, time stamp: 0x5e82ba56

Exception code: 0xc0000005

Faulting process id: 0x324c

Faulting application start time: 0x01d72e8c9d4665e3

Faulting application path: C:\Windows\System32\WUDFHost.exe

Report Id: 3573073f-2b9a-4cc6-90ab-cb0aebf21afd

Faulting package full name:

The error does not occur with the same frequency as with peripherals attached, but it did occur three times during the night. 

Thanks. 

I ran the driver verifier command and got a BSOD with the following listed: "driver_verifer_detected_violation".

The dump file information should be in this link. 

Thanks again for your help.

This SW is NordVPN. I will remove it and see what happens. Thank you. 

Good news. Bad news.

The bad news is I uninstalled the software and the original error  "Windows Driver Foundation - User-mode Driver Framework Host Process - Stopped Working " still occurred. I reinstalled the NordVPN SW and the error still continues to occur as before. 

The good news is the BSOD on startup with the error "driver_verifer_detected_violation" does not occur anymore. 

Thanks for your help so far. Any other suggestions would be appreciated.
