This can be very annoying since it can randomly appear out of nowhere and it will appear while you are using the computer. Worry not, this is not a serious error and we have several solutions for it, so please keep reading and try them as presented in order.

Restart graphic driver

This is the first thing to check if the issue is due to software or driver malfunctioning, there is a shortcut for rebooting graphic driver inside Windows 11. Press WINDOWS + CTRL + SHIFT + B to reboot the graphic driver and see if this fixes the issue. A beep sound should be heard during this process and the screen should turn back to normal.

Check connections

Sometimes the screen can go black due to a faulty connection or cable. If you have it at your hand try a different cable or slightly and gently nudge the existing one to see will screen flicker. If you are on a laptop try gently moving the lid from back to front and pay attention to the screen. If screen flickers or picture returns with this method, cable or connector needs to be replaced.

Clean your computer

The black screen can be because the computer is overheating. If this is the case either fan inside is not working properly or there is a lot of dirt and dust that needs to be removed so airflow can be established again for proper cooling. We have an article on errortools.com on how to properly clean your PC but if you are not technical enough maybe the best solution would be to call someone who is or to take the PC to service for cleaning.

Change The Projection Settings

Press WINDOWS + P to open projection settings, check to see if PC is set to PC screen only. If any other option is selected change it to PC screen only since this can cause random black screen issues.

Scan system for malware

The black screen can also be caused by various viruses and malware. IF you have anti-virus software, run a full system scan to check it for malware. If you do not have one, download a free one and run a system scan, we recommend Bitdefender.

If you encounter an error message that states, “Your computer has lost the lease to its IP Address <IP ADDRESS> on the Network Card with network address <NETWORK ADDRESS>”, then this post might be of help to you.

Blackouts are one of the most annoying things that can happen in the modern age. We have all learned to depend on electricity, maybe too much, so having a backup plan in these unpleasant situations is necessary. Here are some good gadgets for these kinds of situations.

Power Bank

The fully charged power bank is a great item that could fill up your phone or tablet. If it is a larger power bank it could fill them up all the way to the top several times and having charged phone or tablet can help greatly with some fun during dark times. The power bank can also be used to fill up other gadgets on this list so if the power outage is expected to last longer perhaps it would be wiser not to waste it on phone/tablet games.

Portable Generator

If the power bank is too short-lived for your needs, a portable generator is always a good option since it can provide power for longer time periods. The solar generator is what we recommend because it is much cheaper to produce electricity but it is limited if a power surge comes at night, one on gasoline is more stable and practical but it costs more to produce electricity.

Portable Solar Charger

One more electric-producing device on the list, this one however is aimed at charging your phone, tablet, or laptop by harvesting Sun's energy and turning it into valuable electricity for your devices. Fully silent and easy to operate this is a great tool for power outrage. It will not be able to produce electricity for smaller house appliances but for basic phone/tablet/laptop needs it will suffice.

Panic light

Self-sustained with its own battery, panic lights are great assets for lightning when power is not present. They can turn automatically when the circuit detects that power is missing but can be also manually switched on or off. There are many versions of panic lights ranging from the light they produce to how long can they work so picking the right one will depend entirely on your home size and needs.

USB Headlamp

If you lack panic lights USB headlamp is a great choice to light your way and it works even better than a flashlight, although a flashlight is also a great tool, a headlight will provide you with free arms to do various things that you would not be able to by holding a flashlight. Modern headlights come with LED lights so they provide a good amount of light with small power consumption and they can be recharged in a power bank, solar charger, or generator.

LED lantern

LED Lantern is a gadget sitting somewhere between a headlight and a panic light, it offers around the same light amount as a panic light but you can carry it around with you. Of course, it will drain its battery faster than a panic light and it will still need to carry around but it can offer some good options when you need it, like taking it with you to the toilet.

Electric Lighter

An electric lighter is also one of the things that you will need, it can ignite candles, paper, stoves, etc. Its battery is usually enough for extensive use and there are small chances that it will need to be recharged. Having matches is also smart, just in case.

Solar Oven

Great gadget when outbreaks last long or when you get hungry. Not all households have gas ovens so a Solar oven is a great tool to keep you full of food. Granted it will not be on par in speed and quality with a regular oven but when it is the only option it will suffice.

Microsoft has released Windows 11 as a public beta release for all the people that are not willing to be in the insider program. Beta release as of this moment is identical to Insider Preview build 22000.100. and updates will not roll so fast as in insider preview and it is marked as unstable release, same as insider build. I would not install Windows 11 beta on the main PC since some drivers still have issues and may lead to some blue screens. Be aware that the beta build will have all Windows 11 system requirements including TPM 2.0. This is a big difference from insider build which can be installed on systems lacking official requirements. So basically if you have a spare PC that could run Windows 11 install it so you can see what it brings and feel it so you can make a decision will upgrade once it is released later this year.

If you are trying to connect an external device to your computer but you suddenly encounter an error that says, “Device requires further installation”, then you’ve come to the right place as this post will guide you on how exactly you can fix this error. In most cases, USB sticks, headphones, speakers, and other external devices, install drivers automatically once you connect them to your computer which means that the drivers are downloaded and installed in the system as soon as the external device is plugged in. However, if the driver has become corrupted or outdated, you might encounter an error like the

“Device requires further installation”

Aside from corrupted or outdated drivers, the error could also be caused by pending updates, an incorrect version of the Intel PROSet Wireless driver, or checking the wrong event. Whatever the cause is, this post will provide you with some potential fixes that can help you resolve the problem. But before you troubleshoot the problem, ensure that your Windows 10 computer is updated to its latest version and you must also not forget to check that you’re checking the correct event on the Event Viewer. Once you have these things covered, proceed to the instructions below.

Option 1 – Try to update the device drivers to the latest version

One of the most likely root causes of the “Device requires further installation” error is either outdated or corrupted drivers in your computer. This kind of problem is more common on several devices like scanners and printers for which the drivers are provided with them.

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for any outdated device drivers and click on each one of them.
• After that, right-click on each entry of the device drivers and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also opt to download the latest versions of the device drivers directly from the website of the manufacturer. Once you’ve downloaded them, you can install them into your computer right away and then try connecting the external device again. On the other hand, you can also try to reinstall the device drivers.

Option 2 – Try to install the latest version of the Intel PROSet Wireless driver

A lot of users who experience the problem reported that their wireless driver wasn’t also working properly and it was then found that it was caused by the outdated Intel PROSet wireless driver. Thus, to fix the problem, you need to install the latest version of this driver from the intel.com website and install it on your computer. When you download the driver, make sure that your computer is running an Intel system and then download the correct driver depending on whether your computer is a 64-bit system or a 32-bit one.

Windows Updates are checked for their validity every time they are downloaded from Microsoft servers just like how browsers check websites for a valid certificate. And so if you got an error message saying, “ Some update files aren’t signed correctly, error code 0x800b0109 ” while trying to update your computer, it indicates that the Windows service was unable to verify the validity of the Windows Update. To fix this error, you can try out the options prepared in this post.

Option 1 – Reboot your computer and try again

Save your work and reboot your computer and then try checking for updates again. In some cases, all you need is a restart to fix errors like error code 0x800b0109.

Option 2 – Try to update Windows after an hour or so

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it an hour or so before trying to run Windows Update again.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like Error 0x8007001E. To run it, 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 4 – Delete the contents in the Temporary folder

You can also try deleting the contents in the Temporary folder – all the downloaded, pending, or failed Windows 10 updates. You can do that using the simple and easy steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “%temp%” in the field and press Enter to open the Temporary folder.
• After that, select all the folders and files within the Temp folder and delete all of them.

Option 5 – Clear the contents in the Software distribution and Catroot2 folders

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 6 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• 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.)

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.

This is not the first time that Intel is trying to enter the GPU field but its adventures so far were, well let us agree not so good. All of that is hoping to be changed with the upcoming ARC GPU. The first generation of Arc graphics, code-named Alchemist and previously known as DG2, will support desktop PCs and laptops and is set to arrive in the first quarter of 2022. Alchemist will have hardware-based Ray tracing and AI-driven supersampling. This indicates that GPU is aimed to compete in the Hi-end spectrum and battle side by side with Nvidia and AMD on the market. Alchemist will also pack full DirectX 12 Ultimate support. Intel also released names for the next upcoming future generations of ARC GPUs: Battlemage, Celestial & Druid. More information about ARC products will be released later this year. “Today marks a key moment in the graphics journey we started just a few years ago. The launch of the Intel Arc brand and the reveal of future hardware generations signifies Intel’s deep and continued commitment to gamers and creators everywhere,” Roger Chandler, Intel vice president, and general manager of client graphics products and solutions.
