How to Fix Error Code 0xc004f034 in Windows 10

As you already know, the Windows Sandbox is one of the new features in Windows 10. However, just like other new features, it also throws up errors and one of them is the error that states,

“Windows Sandbox failed to start, Error 0x80070057, The parameter is incorrect”.

This particular error in Windows Sandbox occurs due to its dependence on numerous components of Windows 10 that are related to Hyper-V and Virtualization mainly. To fix this error, there are several options you can check out. You can try to install any pending updates on your Windows 10 computer, as well as make sure that all the services related to Windows Sandbox are enabled.

Option 1 – Try to run the Windows Updates to install pending updates

The first thing you can do to resolve the “Windows Sandbox failed to start, Error 0x80070057” is to check Windows Updates in your computer and see if there are any pending Windows Updates you have to install. All you have to do is go to the Windows 10 Settings app and then go to the Windows Updates section and click on the “Check for updates” button to check if there are any pending updates that are needed to be installed. This could fix the Windows Sandbox error.

Option 2 – Ensure that all the supporting processes and services are running properly

If running Windows Sandbox as an administrator didn’t fix the error, you have to ensure that all related processes for Windows Sandbox are running properly. To do that, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, from the list of services, look for the following services in the given order:
  • Network Virtualization Service
  • Virtual Disk
  • Hyper – V Virtual Machine
  • Hyper – V Host Computer Service
  • Container Manager Services
• After you find the aforementioned services, make sure to check if they are enabled or not and then restart each one of them.
• Once done, try to open the Windows Sandbox again and see if the error is fixed or not.

About Browser Hijackers

Browser hijackers (also known as hijackware) are a type of malware that changes internet browser configurations without the user’s knowledge or approval. These kinds of hijacks happen to be rising at an astonishing rate across the world, and they can be truly nefarious and sometimes harmful too. Nearly all browser hijackers are created for marketing or advertising purposes. These are generally used to force visitors to a specific website, manipulating web traffic to generate ad revenue. Even though it might appear naive, these tools are designed by vicious individuals who always attempt to take full advantage of you, so that they could make money from your naive and distraction. Browser hijackers can also allow other vicious programs without your knowledge to further damage your PC.

Signs of browser hijacker malware

Below are some signs and symptoms that indicate your internet browser has been hijacked: your browser’s home page has been reset to some mysterious site; you find redirected to websites you never intended to visit; the default web browser settings are changed and/or your default search engine is altered; you find multiple toolbars on the browser; you’ll find random pop-ups start showing regularly; your internet browser starts running sluggishly or displays frequent glitches; you can’t visit certain sites such as homepages of antivirus software.

How it infects the computer

Browser hijackers can get into a computer by some means or other, including via file sharing, downloads, and e-mail as well. They may also be deployed via the installation of an internet browser toolbar, add-on, or extension. A browser hijacker could also be installed as a part of freeware, shareware, demoware, and fake programs. An example of some infamous browser hijackers includes Babylon, Anyprotect, Conduit, SweetPage, DefaultTab, Delta Search, and RocketTab, however, the names are continually changing. The presence of any browser hijacker malware on your system can substantially diminish the web browsing experience, record your online activities that lead to serious privacy concerns, develop system stability issues and finally cause your PC to slow down or to a nearly unusable condition.

Browser Hijacker Malware – Removal

The one thing you could try to eliminate a browser hijacker is to locate the malicious software in the “Add or Remove Programs” list in the Microsoft Windows Control Panel. It might or might not be there. If it is, try and uninstall it. However, the majority of hijacking codes are certainly not very easy to get rid of manually, as they go deeper into the operating system. Also, browser hijackers can modify the Computer registry so it could be very tough to restore all the values manually, particularly if you are not a tech-savvy person. You can go for automatic browser hijacker removal by just installing and running a reliable anti-malware application. SafeBytes Anti-Malware will counter persistent browser hijackers and provide you real-time PC protection against all types of malware.

Technical Details and Manual Removal (Advanced Users)

If you would like to carry out the removal of RealOnlineRadio manually instead of utilizing an automated software tool, you may follow these steps: Navigate to the Windows Control Panel, click the “Add or Remove Programs” and there, select the offending program to remove. In cases of suspicious versions of browser plugins, you can actually get rid of it via your browser’s extension manager. You will probably also want to reset your internet browser. Finally, check your hard drive for all of the following and clean your registry manually to remove leftover application entries following uninstalls. However, this is often a tricky task and only computer professionals could perform it safely. In addition, some malicious programs have the capability to defend against its removal. Doing this in Safe Mode is recommended.

What is Bandoo?

Bandoo application, specifically product version 5.0.2.4762, is a bundled program. What does this mean? Simply, Bandoo, upon installation, installs additional programs, extensions, and add-ons to a computer and computer’s browser, without the knowledge of the user. This version of Bandoo concentrates on providing features for entertainment and also functionality/tools for backing up your computer files. Once executed, the file installs the iLivid Download Manager Software. Additional tools installed within the bundle include a Movie Toolbar and the thriving search engine ‘Ask.com.’ Technical details about Bandoo include: 

Digital Signature/Publisher:  Bandoo Media, Inc. Product Version: 5.0.2.4762 Entry Point:  0x000038AF

Assessment of Bandoo Potentially Unwanted Program

Interestingly, before the installation of Bandoo product version 5.0.2.4762 was complete, Spyhunter detected that the software was a PUP. After the installation was complete, product version 5.0.2.4762 of Bandoo added add-ons and extensions to both Internet Explorer and Chrome Browsers (these were the only 2 browsers used within the assessment). These appeared in the form of a Movie toolbar, providing quick access to movie trailers, reviews, ratings, and other video functionality, and ‘Ask’ (Ask.com) search engine.

Areas of Infiltration by Bandoo

Bandoo product version 5.0.2.4762 infiltrated several areas of the computer system. After installation, folders were neatly placed as files within all programs. Within “All Programs” there were 3 newly added programs. These included:

• iLivid
• Movies Search App for Chrome
• Movies Search App for Internet Explorer

The iLiVid application seems to be the main offer while the others, namely Movies App for Internet Explorer by Ask was featured as promotions or advertisements. Additionally, just below the 'END USER LICENSE AGREEMENT AND PRIVACY POLICY' a request was made that the user set Ask.com as both their homepage, new tab, and default search engine. This is just another well-concocted plan to get Internet users onto the 'Ask.com' search engine. Along with the 3 programs installed as a bundle,  a new folder was found within the computer's local drive. This program was termed OLBPre.

What is OLBPre?

OLBPre.exe is reputed as dangerous adware that weakens the security settings of a computer system. It's also covertly used for dropping files on a targeted computer, often without the user's consent or knowledge.

Manual Steps for Removal of Movie Search Apps

I found this removal pretty simple. Depending on your Operating System, there will be slight discrepancies in the manual removal steps. Using the Windows 8 (8.1) OS on your computer:

• Step 1: from your desktop, right-click on the ‘Start Button’.  A menu box will then appear.
• Step 2: from the menu box, click ‘Search’.
• Step 3: enter “Programs and Features” within the Input Box.
• Step 4: locate the installed apps. You should be able to see “Movies Search App for Chrome” & “Movies Search App for Internet Explorer”.
• Step 5: right-click on the names of the Apps (the ones you want to remove) when you’ve located them.
• Note: you will have to remove the apps one after the other.
• Step 6: after right-clicking the app, click the uninstall option (probably the only option available anyway).
• Note: If a box appears asking If you wish to ‘block’ or ‘allow’, select the allow option. That’s just the Publisher’s way to annoy you out of uninstalling the app.
• Step 7: follow instructions until the app is fully removed.
• Step 8: Repeat steps for the other app.

Since Bandoo also changed your search engine, you’ll have to reset that manually for Internet Explorer and Chrome. Follow the steps below:

• Step 1: Open your Internet Explorer browser.
• Step 2: Click the tool option located in the top right-hand corner of the page.
• Step 3: Click the “Internet Options” option.
• Step 4: Under the “General” tab, you’ll be able to see approximately 3 buttons. Click the button labeled ‘Use Default”.
• Step 5: At the bottom right-hand corner of the pop-up menu, select the “Apply” button and “OK”. That should do the trick.

Removal for Chrome Extension

This removal is simple.

• Step 1: Open your Chrome browser.
• Step 2: A pop-up box will be visible.
• Step 3: Click the “Remove from Chrome” option.

After removing the extensions/add-ons, perform another scan with Spyhunter. You’ll pick up a few threats. The second scan should clear up everything. To completely remove Bandoo from your computer, click here to download and install Spyhunter.

Direct replacement for Apple M1 Chip is near. There were some M1 Chips versions like M1 MAX and M1 ULTRA that were upgrades of the existing M1 chip, but the new and upcoming M2 is something different and it is aiming to replace M1 completely.

Made in a 5-nanometer design, with 20 billion transistors and 100GB/s of unified memory bandwidth is meant to increase performance over M1. It has the same M1 8 core design with 4 high-efficiency cores and 4 high-performance ones.

All CPU and GPU cores are faster than their M1 equivalents and Apple states that when running M1 and M2 at the same power level M2 will perform 25% faster. The first version of the chip will place focus on power efficiency so if you are more on side of being a power user wait for the MAX or ULTRA version of M2.

Tech details of M2

M2 system on a chip like its predecessor M1 combines both CPU and GPU on a single chip with shared memory in order to increase performance compared to systems that have separate CPU and GPU. M2 so far has been only announced for MacBook Air and the 13-inch MacBook Pro that suppose to hit the market somewhere around July this year. Of course, we expect that M2 is included in future iPad series or Mac Mini series as well.

• CPU Cores: 8
• GPU Cores: Up to 10
• Unified Memory: Up to 24 GB
• Neural Engine Cores: 16
• Number of Transistors: 20 billion
• Process: Second Generation 5nm

One of the cool and interesting features in Windows is the Screensaver which allows users to display animation or change the wallpaper automatically when the computer is not being used. This feature can also time out and lock your computer when it remains idle for quite some time. However, if you notice that the screensaver of your computer turns on a lot earlier, then you’ve come to the right place as this post will guide you on how you can change the timeout settings of the screensaver of your Windows 10 computer.

• Once done, click OK and exit to save the changes made.

Option 2 – Try to change the screensaver time via Registry Editor

The next option you can try to change the timeout settings in the screensaver is using the Registry Editor. To get started, follow these steps:

• Click on OK and exit the Registry Editor to save the changes made.

Option 3 – Change Screensaver timeout settings via Group Policy Editor

• Tap the Win + R keys to open the Run dialog box and type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.

There are times when you might find it difficult to delete folders or files in File Explorer and it could be due to many reasons. One of these reasons can be attributed to the failure that can lock down the folders or files which prevents you from deleting them. In this kind of situation, you can utilize the Command Prompt to delete the folders, sub-folders, and files on your computer, and in this post, you will be guided on how exactly you can do that. Before you proceed, keep in mind that when you use the Command Prompt incorrectly, it might affect your computer and render it inoperable, thus, you must be extra careful when executing the steps given below and it would also be better if you create a System Restore Point. After that, refer to the following instructions. Step 1: First, in the Start Search, type “command prompt” in the field and from the search results, right-click on Command Prompt and then select the “Run as administrator” option to open Command Prompt with admin privileges. Step 2: After opening Command Prompt as admin, navigate to the folder where the file you want to delete is located. Note that you have to execute the “cd” or the change directory command. Step 3: Next, execute the following command in Command Prompt:

DEL /F /A <file path with extension>

Note: In the given command, “/F” is the force delete command, while “/A” is the command that selects the files with the ready for archiving attribute. Step 4: After that, go to the location where you can find the folder you want to delete by using the “cd” command again. And then execute the following command right after:

RD /S <folder path>

Note: In the given command, “RD” is the command that removes the folder from the directory, while “/S” removes all of its sub-folders and files. On the other hand, if you also use the “/Q” parameter, you won’t see the “Y/N” confirmation but if you didn’t use it, then simply tap the Y button to proceed.

Recently, a number of Windows 10 users reported an issue wherein they try to print from their PCs but were unable to and got an error message instead that states, “Port in use, please wait”. However, no matter how long they waited, nothing changed and they were still unable to print from their computers. On the other hand, when some of the users attempted to print wirelessly from their mobile devices, the printing continues which indicates that there is some issue between the computer and the printer. So if you are one of the users who are currently facing this problem, then this post should help. To fix this issue with your Printer, here are some possible fixes you can try that might work.

Option 1 – Run the Printer Troubleshooter

The first thing you can do to fix the “Port in use, please wait” error is to run the Printer Troubleshooter. This built-in troubleshooter in Windows 10 can help you fix most print issues. It checks if you have the latest printer drivers and then tries to fix and update them automatically. Aside from that, it also checks if you have connectivity issues or if the Print Spooler and the required Services are running fine. To run it, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msdt.exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
• Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Option 2 – Try updating the Printer drivers

You might also want to try updating your printer drivers. All you have to do is locate the USB Composite Device. For complete details, follow the steps below.

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the USB Composite Device option and right-click on it, and select the Update Driver from the options.
• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

Option 3 – Try selecting the correct port for your Printer

If the first two options given above didn’t work, then maybe it’s time to select a correct port for your printer since the wrong port has been selected which is why you’re getting the “Port in use, please wait” error.

• Open “Devices and Printers” from the Start search.
• Next, look for your printer from the list of devices and right-click on it, and then select Printer Properties.
• Now go to the Ports tab under the newly opened Properties window and make sure that the port type matches the connection on the list of ports currently in use.

Note: If your printer is using a USB connection then the port should have a USB or DOT 4 in its description but if your printer is using a network connection then it should have the following description:

• WSD
• Network
• IP

And if you notice that there are several listings for the same type of port, you have to change the selection to a different one and then click the OK button to save the changes made.

Option 6 – Try to uninstall the programs you’ve installed recently

In case you don’t know, freeware software packages aren’t always free as some of them could contain malicious software that can cause serious damage to your computer. Thus, if you have installed a program recently prior to getting the “System call failed” error, then you have to uninstall that program.

• Tap the Win + R keys to open the Run dialog box.
• Then type “appwiz.cpl” in the field and tap Enter to open the Programs and Features in Control Panel.
• Next, arrange the list of installed programs in the order of the installation date.
• After that, look for the problematic program and right-click on it, and then select Uninstall.
• Once the process is done, restart your computer and see if the error is fixed.
