Dune, arguably one of the best science fiction novels ever written was brought to a big screen first time by David Linch. Sadly movie itself went through development hell and a lot of troubles and the end result was somewhat strange. The audience was divided on it, some hated it, some loved it but for sure it left a mark in cinema history. Years have passed and just when people forgot about ever receiving another try on a book adaptation Denis Villeneuve has brought his vision of Frank Herbert's novel into its full glory on a big screen. The interesting thing about this new Dune movie was that from the start Denis envisioned it as a two-movie part openly saying that book itself is too complex to be done in a single movie. But, the issue arises when information about Dune part two was hanging on a thread on how well Dune part one will be received and performed in the box office. This naturally brought all kinds of speculation and worry among fans of the franchise, especially because the movie itself was really good and well made. Well for all of you fans and people who wanted to see a continuation of the story can rest at peace now since the Legendary picture has officially announced and green-lighted Dune part two. The budget was given and we can expect part two at the beginning of 2023.

Error Code 0x80072F8F - What is it?

Error Code 0x80072F8F manifests in one main way. It is known to appear as early as Windows 7, and mainly deals with an error that occurs in the update process, or when the computer is trying to connect to the online activation service. It can appear when the activation fails to verify the product key. The error code will present itself when the system realizes that the PC's date and time are incorrect. Error Code 0x80072F8F will also appear if the computer has determined that the time zone settings on the computer are not accurate.

When Windows is going through the installation process and is verifying all of the information associated with the computer, Error Code 0x80072F8F will arise, indicating that the information in the computer's settings is not valid. Correct times and dates are necessary when using serial validation keys to install Windows. When these settings are outside of the tolerated window, the problem will arise.

Error Causes

There is only one main symptom to look out for, and it will manifest during a Windows installation. In the midst of the installation, the computer will not be able to proceed with the installation if Error Code 0x80072F8F has popped up. Because the information cannot be verified, Windows will not be able to continue the installation process when the time settings are not accurate. This interrupts the process, causing the need to edit the settings, restart the computer, and try again. It is imperative to be sure that the date and time on the computer are inside of the tolerated window for the serial key.

• This error code will not give any information on how to correct it.
• Windows Error 0x80072F8F is displayed on the screen.
• The error code appears when typing the Windows serial key and proceeding.

Further Information and Manual Repair

When experiencing Error Code 0x80072F8F, the date and time need to be corrected in the computer settings menu, and then verify the correct time zone settings.  There are a few different ways to edit the time and date settings, and one may need to even edit the time zone settings. After this, restarting the computer may be needed. When booting into Windows, the validation code should be activated within 30 days of obtaining the serial number.

• Method One

Check the time and date settings.

1. Open the Start menu.
2. Select Settings, then Time and Language, then Date and Time.
3. Check and make sure that the PC is operating at the correct time and date.

• Method Two

Ensure that the computer is connected to the internet.

1. Enter “network troubleshooter” into the search box located on the taskbar.
2. Select “Identify and Repair Network Problems”.
3. Follow the instructions that are given on-screen. This will fix any problems that the network is experiencing.

• Method Three

Review the timezone.

1. Open the Start menu.
2. Select Settings, then Time and Language, then Date and Time.
3. Check to make sure that the correct timezone is selected from the drop-down menu.

• Method Four

Reboot the PC and check if that fixes the problem. This may help in the event that the network troubleshooter does not detect a problem.

After completing these steps to edit the time, date, and time zone settings, it may be necessary to restart the computer. This is to ensure that the computer will save and recognize the new settings. After restarting, continue the process as intended and enter the product key. The computer will now be able to verify the product key since the time and date will be recognizable. The Windows installation should proceed as normal and complete successfully when the time, date, and time zone are inside of the parameters for the Windows product key.

In short, if it is not, the computer will not be able to recognize the product key, thus will not be able to install the Windows product. Generally, the fix is quite simple and does not take much time at all, but it is very important.

When you update or upgrade your computer to Windows 10, the setup will look for the compatibility of both the hardware and software. And in this process, if suddenly got an error message saying, “Some apps need to be uninstalled” or “You need to uninstall a program in order to continue”, you have to look for the program(s) that might be causing the compatibility issues. But worry not as this post will help you resolve the issue. Simply follow the given suggestions below.

If the display of your Windows 10 computer turns on all of a sudden no matter how put it to sleep over and over again, it always wakes up, read on as this post will guide you in resolving this peculiar issue. In case you don’t know, the Windows 10 computer Sleep state is made in such a way that if it’s really important, it wakes up. You may have configured this kind of behavior or there could be some hardware component that’s interrupting its Sleep state. Thus, this post will give you some troubleshooting tips to fix the Sleep state issue caused by the Legacy Kernel Caller. The Legacy Kernel Caller points to the external hardware that’s causing your Windows 10 to wake up even when it’s in a Sleep state. Step 1: Find out what’s keeping your computer from going to sleep. To figure out what really is keeping your computer from going to sleep, you can execute the “powercfg –requests” command instead of checking the power configuration of your computer. This command will look for requests from applications and drivers that prevent the computer from turning off the display or from going to sleep. To execute the command, simply open Command Prompt and type “powercfg –requests” and hit Enter. After that, you will see part of the result that looks like this:

“SYSTEM [DRIVER] USB AUDIO DEVICE An audio stream is currently in use [DRIVER] Legacy Kernel Caller.”

Step 2: The next thing you have to do is remove all the external hardware connected to your computer. In this step, you have to disconnect external hardware from your computer. Based on reports from users who experienced the same issue, the “TV card” is the culprit so make sure you remove that one. Once you’ve removed it, open Command Prompt and run the “powercfg –requests” command again and you’ll see that the “Legacy Kernel Caller” will no longer be on the list. In addition, your computer will get into its regular sleep mode once the hardware is removed. Once you do that, the driver gets hung and won’t release the power request despite being used. Step 3: Try using the request override option The powercfg command also offers a request override option which allows users to disable the requests from applications and services to wake the computer from sleep mode. To run this command, simply open Command Prompt with admin privileges. After you open Command Prompt, type the following command and hit Enter to disable requests from applications and services that causes the computer to wake from sleep state.

Powercfg -requestsoverride Driver "Legacy Kernel Caller" System

Step 4: Check the streaming and media applications You also have to check if your computer is running an audio or video service in the background. In such cases, your computer won’t be able to go to sleep mode if these services are running in the background. You might have noticed that when you play a video or audio, your computer never goes to sleep. And if you have put it to sleep in between watching the video, then it’s probably why your computer is waking up. Thus, you have to stop these services. Step 5: Check the devices that can wake your computer If you didn’t see the Legacy Kernel Caller in the result after you execute the ”powercfg –requests” command, then you can try to execute the following command instead.

powercfg –devicequery wake_armed

After you enter this command, it will give you a list of all the devices that can wake your computer. So if there is anything other than the mouse, keyboard, touchpad, you have to check the power configuration of that device. To do that, go to the Device Manager and disable the device’s “Allow this device to wake the computer” option in its Properties Step 6: Check the Sleep Advanced Settings

• Click on the Windows key and type “control panel” in the field and select the related search result.
• Next, select the Security and Maintenance option and click on the Power Options.
• After that, you have to select the Change Plan Settings but keep in mind that this option is barely readable so you need to read each option carefully.
• Now click on the Change advanced power settings button and a new window will appear.
• Then look for the “Sleep” option and expand it. Make sure that the “Allow hybrid sleep” option is on.
• Reboot your computer and check if your computer now functions properly. If it still didn’t work, you may have to reverse the changes you’ve made.

On the other hand, you could also run the Power Troubleshooter to resolve the Sleep state issue. This built-in troubleshooter will automatically fix any power-related issues in your computer.
