Fix DRIVER_VERIFIER_DMA_VIOLATION Error

There are many times when you have to change the ownership of a folder or a file so that other users can use them as well or if you want to transfer files to them, or an old account has been removed and all the files need to be assigned to a new user. Windows 10 keeps all these files locked under the account by default which created a folder or file. So unless a user is an admin or if the file belongs to that particular user, other users won’t be able to access or edit the file. So if you want to change the ownership of a folder or a file, then you’ve come to the right place as this post will guide you on how exactly you can do that.

To get started, make sure to follow the instructions provided below carefully.

Step 1: First, you need to open File Explorer by tapping the Win + E keys. Once you’ve opened it, navigate to the folder or file that you want to change the ownership. Step 2: Right-click on the folder or file and click on Properties and then go to the Security tab. Step 3: From there, click on the Advanced button located at the bottom right part of the window to open the Advanced Security Settings of the folder or file. Step 4: As you can see, the current owner will be listed with the Change link available next to the “Owner” label. Now click on this link to open the Select User or Group window. Step 5: After that, click on the Advanced button once again and click on the “Find Now” button to see the list of all the users as well as groups that are available in the computer. Step 6: Then select the user you want to give ownership to and click on the OK button and then click the OK button once more to save the changes made. Step 7: This will take you back to the Advanced Security Settings window but this time, the owner will be changed to whoever user you’ve selected. But you’re not done yet as you still have to check two additional options to help you completely transfer the ownership of the sub-folders as well as the files. You have to check the checkbox of the following options:

• Replace owner on sub-containers and objects
• Replace all child permission entries with inheritable permission entries from the object.

Step 8: After that, you need to click the Apply and OK buttons to confirm and save the changes made. This will completely transfer the ownership of the file. However, there is still one last thing you have to do – you have to go back to the Advanced Security Settings window to remove the access of any other user on the folder or file. Once you’re there, remove the existing user to make sure that the only assigned user has the access to the folder or file.

If VirtualBox suddenly displays a black screen without any text or mouse cursor when you are trying to boot a guest operating system, then read on as this post will guide you in fixing such an issue. This black screen occurs when Windows 10 failed to provide a specific setting that VirtualBox requires. Consequently, you will not be able to install or use any guest operating system in VirtualBox even if your PC has virtualization support, the best thing you can do now is to fix this black screen issue. There are two ways you can fix this black screen in VirtualBox, you can either try to disable Hyber-V or disable 3D Acceleration. For more details, refer to each one of the given options below.

Option 1 – Try to disable Hyper-V

Hyper-V is a built-in virtualization tool available in Windows that helps users in creating a virtual machine as well as install a guest operating system without using any third-party tool like VMware, VirtualBox, and many more. However, the problem with this virtualization tool is that some systems cannot run it and VirtualBox simultaneously which is most likely why the screen abruptly turns into black.

Option 2 – Try to disable 3D Acceleration

The guest operating system will use the host computer’s GPU to render 3D graphics if you enable the 3D Acceleration for the virtual machine. To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem. In fact, a lot of operating systems have failed to use the 3D Acceleration for the guest operating system because of this black screen issue. To disable it, follow these steps:

• Open VirtualBox on your computer and select the virtual machine.
• Next, click on the Settings button and go to the Display section.
• After that, look for a checkbox named “Enable 3D Acceleration” located on your right-hand side and then uncheck it.
• Save the changes you’ve made and reboot your PC and see if you can now run the virtual machine without any problem.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 2 – Try to change the USB port

You might want to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it.

A lot of users connect to the internet are using VPN on their Windows 10 computers which means that their regions could be different from the actual region of their Windows 10 computers. Thus, if you are facing some issues in updating your computer in this kind of environment, specifically the Windows Update error 0x800F0922, you need to follow the tips given in this guide to help you resolve the issue. When you encounter this kind of Windows Update error, you might see either of the following error messages on your screen:

“Windows could not search for updates, Code 0x800F0922 Windows Update encountered an unknown error” Or: “Windows failed to install the update with error 0x800F0922”
