VirtualBox displays Black screen

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.

Ways to lose your Facebook account to hackers
Facebook graphicsToday most people have Facebook accounts where they keep in touch with friends and family. But large Facebook network of users is also very interesting to another party as well, hackers. There are many ways hackers can steal your data via direct hacks, trickery, and social engineering in order to get your credentials, emails, and many other things using them to wreak further havoc. Once a hacker has needed information it is very difficult to minimize impact and all of your information could be compromised from a list of friends to credit card numbers. Keep on reading to learn how can you protect yourself against these attacks and learn about common practices that hackers use in order to steal your data.

Stealing Facebook data via email

A couple of years ago there was a lot of talk about not opening suspicious emails. Well, it still holds today. The difference is that today’s fake emails have become very difficult to differentiate from official ones since hackers put the effort into creating them copying fonts and layout, making them identical to original ones. So if emails look and feel like original ones how do you know if it is fake? Very simple, you do not click anything in it. If Facebook or for that matter any company wants to contact you they will do via their platform. Clicking inside a hacker's email will lead you probably to a fake Facebook website replica where you will have to type in your username and password providing an attacker with your login credentials, etc. If you receive this kind of mail where there are threats about terminating an account, missing payments, etc. it is always the best thing to go directly to Facebook and see if you have any kind of notifications there. Do not trust any emails that ask for account information, request money, or threaten to suspend your account.

Phishing attacks

As stated previously if you click on the link inside fake mail it will probably lead you to a website replica of the original. Although hackers can pretty much copy all things from an original website like layout, fonts, colors, etc. There is one thing that he cannot, web address. Take a good look into your browser address bar to see if there is a typo or anything strange in the address of a website. Also, make sure to check for the secure icon in the web address before signing in.

Fake Facebook buttons

If by any chance and for whatever reason, you end up on a fake Facebook site be vary careful about like and other buttons since buttons themselves behave and act like links inside your browser. IF when you click on like you get a prompt to sign in, it is almost 100% that you ended up on a phishing fake website.

Password brute force attack

Having complex and long passwords is a must. If your Facebook password is 12345 there is a very high chance that if a hacker wants he can easily guess it via trying out the most used and simple passwords via simple guessing. To avoid being hacked just for having poor passwords try to think of something longer, combine letters and numerical characters, place special characters inside it or just simply as the best solution use a password manager and create passwords with it.

Password grab outside Facebook

If you use the same password for multiple accounts which is a big no-no and you should not do it then hackers can use passwords from other services and login into your Facebook in order to steal data. Avoid these situations by having different passwords for different accounts or use a password manager to keep everything in order.

Hacking via key logger

Some time ago we have made an article which explained in detail everything you need to know about key loggers here: https://errortools.com/windows/how-to-know-if-you-have-keylogger-in-windows/ Anyway, this is a more advanced hacking technique in order for hackers to steal your data and it includes placing malicious applications into your system that records your keystrokes and sends them directly to hackers. Since this is an application best protection against this type of attack is to have a security suite installed and active on your PC or device you use to go to Facebook.

Connecting and surfing on an unsecured network

Using no password and unsecured WI FI or any other type of network is risky at least. You can have all protection installed on your device and have a strong password but hackers also logged in to the same network can track all outgoing stuff going through mentioned network leaving you again exposed to attacks. It is better to connect to your mobile operator network than on free WI FI, at least there is some level of security in your operator network while free WI FI is completely unsecured. Getting a virtual private network or VPN is also one thing you could think about for protection since almost all VPN services will encrypt your data thus providing you with a security layer even on unsecured Wi-FI.

Conclusion

Hacking and stealing have come a long way from their infant stages and in today’s world when we use a lot of gadgets and have plenty of online presence taking some steps for security is a must. I hope that you have found anything here informational and helpful so you can avoid getting your data compromised.

Run Windows Updates from Command Line
As you know, one of the most highlighted features of Windows 10 is Windows Updates. It was offered to the customers as a service rather than a product with the release of Windows 10 under the scenario of Software as a Service which led to Windows Updates being set by default on Windows 10 and without an option for any users to disable it. Although not all users are happy with what Microsoft did, this is an ultimate step towards the greater good of all its customers since Windows Updates helps users in keeping their computers secured against all kinds of threats as well as provide them with the greatest and latest updates from Microsoft. So if you are one of those users who approved of the Windows Updates service, then read on as this post will guide you in running Windows Updates from Command Line either via Command Prompt or Windows PowerShell. For the complete set of instructions, refer to the options given below.

Option 1 – Run Windows Update via Command Prompt

Command Prompt in the Windows operating system exists for a very long time now compared to the comparatively new Windows PowerShell. That’s why it has similar capabilities to run Windows Updates. However, the highlighting point here is that you don’t have to download any module for Windows Updates. To get started running Windows Updates using Command Prompt, refer to the steps below.
  • First, type “cmd” in the Cortana search box, and from the search results, right-click on Command Prompt and select the Run as Administrator option to open it with Administrator privileges.
  • If a User Account or UAC prompt appears, just click on Yes to proceed.
  • Next, type in the commands listed below, and don’t forget to tap Enter right after you type each one of them.
    • UsoClient StartScan – use this command to start checking for updates.
    • UsoClient StartDownload – use this command to start downloading updates.
    • UsoClient StartInstall – use this command to start installing the downloaded updates.
    • UsoClient RestartDevice – use this command to restart your computer after you install.
    • UsoClient ScanInstallWait – use this command to check, download and install updates.
Note: Keep in mind that the commands in Command Prompt listed above are only meant for Windows 10. On the other hand, if you are using an older Windows version, you can try using the following commands instead:
  • wuauclt /detectnow – use this command to start checking for updates.
  • wuauclt /updatenow – use this command to start installing the updates detected.
  • wuauclt /detectnow /updatenow – use this command to check, download and install updates.

Option 2 – Run Windows Updates via Windows PowerShell

If you run Windows Updates in the Windows PowerShell, it will require you to install the Windows Update module manually. Hence, you have to get the Windows Updates downloaded and install Windows Updates.
  • Search for PowerShell in the Cortana search box and then run it with administrator privileges.
  • Once you’ve opened the Windows PowerShell, type the following command and hit Enter.
    • Install-Module PSWindowsUpdate – use this command to install the Windows Update module for Windows PowerShell.
    • Get-WindowsUpdate – use this command to connect to the servers of Windows Update and download the updates if found.
    • Install-WindowsUpdate – use this command to install the Windows Updates you’ve downloaded to your computer.

Fix Error 0x80244018 when Installing Apps
If you suddenly encounter an error saying, “Something happened and this app couldn't be installed. Error Code: 0x80244018”, when trying to install apps on your Windows 10 computer, then you’ve come to the right place as this post will help you in resolving the problem. It’s not just you that’s experiencing this problem right now as several users also reported getting this error they try to apply a Windows update or download and install the application from Microsoft Store. There could are several reasons why you’re getting this error. It could be caused by a third-party application, or it could be that the update is blocked by your VPN or proxy server, or that the BITS service is disabled. In addition, the error could also be due to some glitch in the component services or it could be that the system files are corrupted. Whatever the cause is, you can fix the error by following any of the given options below.

Option 1 – Run the Windows Update Troubleshooter

Running the Windows Update Troubleshooter can help in fixing Error Code 0x80244018. 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 2 – Put your PC in a Clean Boot State

It could be that some third-party application is the one that’s causing the problem so it’s best if you put your computer in a Clean Boot state. 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.)
  • After that, try to install the Windows app again.
Note: If you are able to install the app without any trouble at all then it means that the error is caused by some third-party application on your computer. You need to look for the culprit and uninstall it once you found it.

Option 3 – Restart BITS

The Background Intelligent Transfer Service or BITS is a part of the Windows Update service and is the one that manages the background download of Windows Update, as well as scans for new updates and so on. And if Windows Update is experiencing some problems, you can try restarting BITS but make sure that you have admin privileges to do so.
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “services.msc” in the field and hit Enter to open Windows Services.
  • From the list of Services, look for the Background Intelligent Transfer Service and double-click on it to open Properties.
  • After that, you need to set the Startup type to “Automatic (Delayed Start) and click on Apply.
  • Now click the Stop button to stop BITS and then click the Start button to restart the service.
  • Click OK to save the changes made and then restart your PC.

Option 4 – Disable the Proxy server

  • Tap the Win + R keys to open the Run dialog box.
  • Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
  • After that, go to the Connections tab and select the LAN settings.
  • From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
  • Now click the OK and the Apply buttons.
  • Restart your PC.
Note: If you are using a third-party proxy service, you have to disable it.

Option 5 – Try disabling the VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting Error Code 0x80244018 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least after you’ve successfully installed the app.

Option 6 – Reset Windows Update components

  • Open Command Prompt with admin privileges.
  • After that, type each one of the following commands and hit Enter after you key in one after the other.
    • net stop wuauserv
    • net stop cryptsvc
    • net stop bits
    • net stop msiserver
Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.
  • After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
    • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
    • ren C:WindowsSystem32catroot2 Catroot2.old
  • Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
    • net start wuauserv
    • net start cryptsvc
    • net start bits
    • net start msiserver
  • Close Command Prompt and reboot your PC.

Option 7 – Run the System File Checker Scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be the cause why you’re getting the Error Code 0x80244018. To run the SFC command, follow the steps given below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Restart your PC.

Option 8 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help in fixing the Error Code 0x80244018.
  • Open the Command Prompt with admin privileges.
  • Then type in the following commands and make sure to hit Enter right after you type each one of them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • exe /Online /Cleanup-image /Restorehealth
  • Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Disabling the Blur on Login Screen in Windows
You will notice the blurred background on the login screen right away when you start your Windows 10 computer that’s running the v1903 and up. This kind of blurred background is known as “Acrylic Blur Effect on Sign-in Screen”. This new feature delivers a beautiful experience to users by adding more focus to the login screen. However, no matter how nice this feature is and even if it only stays for less than a minute, not all users like it and if you’re one of these users, read on as this post will guide you in disabling the blurred background login screen in your Windows 10 computer. Disabling the blurred background in the login screen can be done in two methods. The first one is via the Registry Editor and the second one is via the Group Policy Editor. Before you proceed, make sure that you are using an admin account and you must create a System Restore point first. Once you have that covered, follow the options provided below.

Option 1 – Disable the Blurred background in the login screen via Registry Editor

  • First, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and hit Enter to open the Registry Editor.
  • After that, navigate to this registry path: KEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
  • Next, right-click on any empty space in the right pane and create a new DWORD (32 bit) and name it as “DisableAcrylicBackgroundOnLogon”.
  • Once you’ve created the DWORD, double click on it and set its value to 1 to disable it and 0 to enable it.
  • After you make the necessary changes, restart your computer. You won’t now see the blurred background on the login screen.
Note: No matter what option you select to change the background, it will stay blurred when you click on the login button. At the time of writing, there is no way to disable this feature in the Personalization section so the Registry Editor will have to suffice for now.

Option 2 – Disable the Blurred background in the login screen via Group Policy Editor

  • Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
  • After that, navigate to this policy setting: Computer ConfigurationAdministrative TemplatesSystemLogon
  • From there, double click on the “Show clear logon background settings” and since its default value is “Not configured”, set it to “Disabled”. You will see the following description under this setting:
    • “This policy setting disables the acrylic blur effect on the logon background image.”
    • “If you enable this policy, the logon background image shows without blur.”
  • Now click on OK and then check the login screen.
Note: If you don’t configure or if you disable this policy, the logon background image adopts the acrylic blur effect. However, if it didn’t work, you have to restart your computer and then check.

How to choose default applications in Windows
Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever. Luckily we can easily change which application Windows uses for which file type. Click on ⊞ WINDOWS to open the start menu and choose settings. Windows 10 Star menu with marked settings iconOn the settings screen, choose Apps. Windows settings apps section markedWhen the Apps screen opens on the left click on Default apps.

Software Licensing Service 0xC004F009 Error
A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:
“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”
One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

  • First, you need to obtain your MAK key from the IT administrator.
  • Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
  • After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
  • Next, type another command and hit Enter: slmgr.vbs –ato
  • Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.
  • In the Start Search box, type in “Slui 4” and tap Enter.
  • Next, select your country and click on Next.
  • Keep the window open and call the toll-free number of the country you’re from.
  • Afterward, a confirmation ID should be given by the automated system which you must take a note of.
  • Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.
  • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
  • After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
  • Next, change the value of the “mediabootinstall” key to “0”.
  • Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
  • The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.
  • Go to Settings and then select Activation.
  • After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

  2. Select the Privacy tab.
  3. Select the following checkbox: Prevent Cross-Site Tracking.
Safari will now prevent these trackers from following you across the World Wide Web.

CHROME

As you’re browsing the web, Chrome can send a request for websites not to collect or track your browsing data. It’s important to note that this is a request, so there’s no guarantee that every website will honor the request. Frustratingly, Chrome doesn’t provide information about the websites that are tracking you online. However, we still recommend enabling this feature, as it can help minimize the number of websites that are tracking your online movements:
  1. In Chrome’s upper-right corner, select the three-dot menu icon, then Settings.
  2. In the menu on the left, select Privacy and security.
  3. Click Cookies and other site data.
  4. Find the Do not track slider and push it into the On position.
Now Chrome will send a Do Not Track request to every website you visit. Since this is only a request, you may want to take additional steps to protect your online privacy. Ghostery is a Chrome extension that enables you to view and block online trackers. After installing Ghostery, you can view all the trackers that are active on a particular website:
  1. Head to the site in question.
  2. Click the Extensions icon in the Chrome toolbar.
  3. Select Ghostery to see a list of all the trackers this extension has detected.
  4. You can block all of these trackers by selecting the Detailed tab and then clicking Restrict site.
Repeat this process for every site you visit.

MOZILLA FIREFOX

Firefox has an Enhanced Tracking Protection feature that can block all the cross-site trackers identified by Disconnect. This feature can also preserve your online privacy by blocking social media trackers, fingerprints, and crypto miners, making this a great all-arounder for the security-conscious Internet user. Enhanced Tracking Protection should be enabled by default. However, you can verify whether it’s active for your particular Firefox installation by navigating to any website. Next, click the little shield icon that appears alongside Firefox’s address bar and you should see a message confirming that Enhanced Tracking Protection is enabled.
If Enhanced Tracking Protection isn’t enabled, we recommend activating it:
  1. In Firefox’s upper-right corner, select the three-line icon, then Preferences.
  2. In the menu on the left, select Privacy & Security.
  3. You can now select either Standard or Strict. Note that Strict may affect the functionality of certain websites, so it’s recommended you opt for Standard unless you specifically require a greater level of protection.
Similar to Chrome, Firefox can send a Do Not Track request. While you’re in the Privacy & Security menu, you may want to consider activating Mozilla’s Do Not Track feature.

OPERA

When you first installed Opera, it gave you the option to block trackers. If you didn’t take Opera up on the offer then, you can start blocking trackers now:
  1. Along the left side of the Opera browser, click the cog icon. This opens Opera’s settings.
  2. In the menu on the left, select Basic.
  3. Find the Block Trackers slider and push it into the On position.
  4. Blocking trackers can impact the functionality of certain websites. If you start noticing strange behavior on a particular website, you may want to add that site to your Exceptions list. By allowing this site to use trackers, you should be able to resolve any issues you’re experiencing.
To make an exception for one or more websites:
  1. Launch Opera’s settings by clicking the little cog icon.
  2. Navigate to Basic > Manage Exceptions.
  3. Click Add and then type the address of the site where you want to permit trackers.
Repeat for all the sites that you want to add to your exceptions list.
