Cortana can understand natural language and context, there's no particular set of commands to make things happen. In a sort of way, you are speaking to Cortana as you would to any other person.

Invoking Cortana

Before using voice commands, it's important to know the ways in which you can invoke Cortana using natural language:

• You can click the microphone icon in the taskbar next to the Start menu.
• You can use the Shift + ⊞ Windows + C keyboard shortcut to open Cortana in listening mode.
• You can use the Hey Cortana feature, which lets you invoke the assistant by simply saying Hey Cortana followed by the command. For example, Hey Cortana: How's the weather?.
• On Windows 10 Mobile devices, you can press and hold the search button to open Cortana in listening mode.

Comprehensive list of Cortana voice commands

The following list of commands are examples you can use to learn how to control Cortana with voice commands. Keep in mind that there isn't a specific way to speak the commands. For example, Hey Cortana: Let me listen to some tunes is the same as asking for a more systematic command like Hey Cortana: Play music.

As you know, every Windows Update is essential for every Windows operating system. They have to be regularly installed, especially since they include various security updates that are important to the system. However, there are times when Windows Update fails to execute properly and you get errors like the error code 0x80070BC9. When you encounter this particular Windows Update error, you will get the following error message on your screen:

“0x80070BC9 – ERROR_FAIL_REBOOT_REQUIRED. The requested operation failed. A system reboot is required to roll back changes made.”

This kind of Windows Update error is most likely caused by a newly installed problematic software, corrupted Windows Update files, or policies that restrict the behavior of the Windows Module Installer. The Windows Module Installer, also known as “WMIW” or “TiWorker.exe”, is the one that checks for new updates from the Windows server and installs them on your computer. This is why you need to make sure that you do not have any policies that control the start behavior of the Windows Module Installer since this service must not be hardened to any start value and should be managed by the operating system. To resolve the Windows Update error code 0x80070BC9, you can check out the options provided below.

Option 1 – Try checking the status of the Windows Modules Installer Worker Service

Since the Windows Update error code 0x80070BC9 has something to do with the Windows Module Installer Worker service, you need to check its status in the Service Manager. Refer to the following steps to do so.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “MSC” in the field and hit Enter to open the Services Manager.
• After opening the Services Manager, look for the Windows Modules Installer Worker Service.
• Once you found it, check its status and make sure that its Startup type is set to Manual.
• Now click on the Start button and see if it fixes the Windows Update error.

Option 2 – Run the Windows Update Troubleshooter

You might want to run a built-in Windows Update troubleshooter to resolve the Windows Update error. It is one of the things you can check out as it is known to automatically resolve any Windows Update errors like error code 0x80072EE2. To run this troubleshooter, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 3 – Try contacting the IT administrator to modify the group policies

You could also try to contact the IT administrator to have the group policies modified. This option is applicable for company-managed systems. As mentioned, one of the possible causes of the Windows Update error 0x80072EE2 is the policies that control the start behavior of the Windows Module Installer. Thus, you need to have them removed so that the Windows Module Installer Worker service is managed by the operating system itself. And since there could be many policies, it is highly advised that you contact your company’s IT administrator to get the job done for you.

Option 4 – Try to install the Windows Updates in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing Windows Update error code 0x80070BC9. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

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. Thus, you have to disable Hyper-V to resolve the problem. How? Refer to these steps:

• In the Start Search, type “Turn Windows features on or off” and then click on it from the results.
• Once you’ve opened the Windows Features window, remove the checkmark from the Hyper-V box.
• Click the OK button and then restart your computer.
• Now try to use VirtualBox again and see if the problem is fixed.

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.

Error code 0Xc004F074 - What is it?

Did you previously use Windows 7 or 8 but decided to run with the latest Windows 0S, Windows 10? An early error message encountered was activation error code 0Xc004F074. Error code 0Xc004F074 is manifested when the user fails to activate Windows directly after the installation of Windows 10. This occurs if the previous operating system on your computer was Key Management Service (KMS) activated.

The KMT provides a more seamless operation when users are activating volume license editions of Microsoft Windows and Office. This process tends to be clear to end-users of the system.

Symptoms of error code 0Xc004F074 include:

• Windows is unable to reach your company’s activation service.
• The Key Management Service is unavailable.

Solution

Error Causes

Various factors might incite error code 0Xc004F074. A primary cause is a discrepancy or difference between the KMS client and the KMS host machine. The host computer could possibly be operating a Windows Server 2003 or Windows Server 2008, while the client runs on OS Windows 7 or Windows Server 2008 R2. To supplement, the computer’s time might be a contributing factor. The time on the host machine and client might show a difference (Usually the host time exceeds 4 hours).

Further Information and Manual Repair

To rectify error code 0Xc004F074, users are advised to try various methods. These methods include:

1. Method 1: Update Your KMS Host 9 (Windows Server 2003)

Are you running later versions of Windows Server? Use an update that fixes or installs KMS on your computer. The update is available on Microsoft’s website. Keep clearly in mind that the update is only for Windows Server 2013 Service Pack 1 and later versions of Windows Server 2003.

2. Method 2: Update Your KMS Host 9 (Windows Server 2008)

This step is similar to the aforementioned. However, it applies to Windows Vista and Windows Server 2008. This ensures the service is extended to Windows 7 and Windows Server 2008 R2.

3. Method 3: Update the Time

It was previously mentioned that the time reflected on the KMS host and client might cause error code 0Xc004F074 to manifest. A simple fix to adhere to is to always ensure that the time between both is updated. To Resync the time on the client, execute the following command.

w32tm /resync

4. Method 4: Uninstall the Existing KMS

For this method to be successfully deployed, you’ll need to have in your possession an activation key or KMSpico Key. As you cannot apply the new key with the existing one, remove or uninstall the initial key. To perform this step, open the command prompt. This should be done while the computer is in admin mode. Then, run the command

(slmgr.vbs /dlv)

It should be executed without the brackets and before you have removed the existing key.

After executing the command, you’ll encounter the description:

Windows(R) Operating System, VOLUME_KMS_WS12_R2 channel

Move along with the process by applying the slmgr.vbs /upk to uninstall the existing KMS key.

After the old key is uninstalled, you’re ready to apply the following:

slmgr.vbs /ipk <NewKMSProductKey>

To check if things are in place and complete the process, follow the steps below: PC Settings >Update and Security > Activation

5. Method 5: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.
