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.

What is this particular error?

One common issue when trying to upgrade to Windows 10 from Windows 7 or 8 is incompatible software. Any installed software or app that isn’t compatible with Windows 10 will prevent you from continuing with the set-up. Normally, you’ll get an error message “What needs your attention” and it will ask you to uninstall a list of apps manually. Unfortunately, some users reported that they couldn’t find the app it asks to uninstall. In some cases, users said they’ve already uninstalled the app but it still won’t start the Windows 10 Setup.

Solution

Error Causes

This type of issue normally occurs because of the following:

• Incompatible software/apps
• Corrupted software/apps
• Incomplete uninstallation

Further Information and Manual Repair

Here are some steps you can take whenever you encounter this error.

Note: Before taking any steps, make sure that you’re highly equipped to do so. Some steps might affect the system and even do more damage to your computer. You might also want to consider using an automated tool instead.

Method 1 – Perform a clean boot, then retry upgrading

A clean boot is normally done to start Windows using the least set of drivers and startup programs available. By doing this, it eliminates possible software issues that happen when installing or uninstalling a program in Windows 10.

Before performing a clean boot, make sure to take note of the following:

• You need administrative privileges in order to perform this action.
• When doing this, your computer might lose temporarily functionality. However, it will return after start-up.
• It is highly advisable to not use the System Configuration to change advanced boot options.

Here are the steps to perform a clean boot.

• Step 1 – Go to Start and search for msconfig
• Step 2 – Go to System Configuration
• Step 3 – Under Services tab, click on the “Hide all Microsoft services” checkbox. Then, choose to Disable all
• Step 4 – Go to the System Configuration’s Startup tab. Then, click on “Open Task Manager”
• Step 5 – In the Task Manager dialog box, you will see a Startup tab. Choose items that you want to disable and then click the Disable button
• Step 6 – Close the Task Manager dialog box.
• Step 7 – Go back to the Startup tab of the System Configuration box. Click “Ok” then proceed with restarting.

Method 2 – Manually uninstall programs from the Program Files folders

Instead of using the “add or remove programs” feature in Windows, you might need to manually install the program directly from the C drive. To do this, follow the steps below:

• Step 1 – Go to the C drive, and look for the Program Files folders. For 32-bit users, you can find it at C:\Program Files. If you’re using the 64-bit version of Windows, go to C:\Program Files (x86) folder.
• Step 2 – Find the “uninstall” application file
• Step 3 – Right-click, and run the file as administrator. Wait for the uninstallation to finish. In some software, you need to restart your system before the uninstallation will take effect.

Note: In some cases, you may also need to search for files related to the program. You can use the search bar under Drive C to do this. Delete those files as well.

Method 3 – Create a new user account

Before upgrading to Windows 10, create a new user account. Make sure it has administrative privileges. From there, run the upgrade.

Method 4 – Use third-party uninstaller services

If you still can’t run Windows 10 Setup after the above methods, you might need to rely on a third-party service. Microsoft recommends Revouninstaller that can help you.

Before using this software, reinstall the application or utility that Windows 10 wants you to install. Then, use Revouninstaller to delete the program completely.

Method 5 – Disable third-party antivirus software

Some users who experienced this issue reported that it was solved after disabling or completely uninstalling the anti-virus software installed in their system.

Method 6 – Use a trusted automated tool

If after trying the above methods, the problem still persists, it might be best to use a trusted automated tool to fix the issue.

As you know, Microsoft’s consumer cloud storage platform is none other than OneDrive. It is where users can save any of their files albeit it’s mostly used to store common files like documents and photos. However, there are times when you might encounter some problems when saving these files. Recently, some users reported that they had problems saving Word documents to OneDrive and if you experience the same issue, then you’ve come to the right place as this post will guide you on how to resolve it. According to users who encountered the problem, when they try to save Word documents on OneDrive, an error message appears instead stating, “This is not a valid file name”. This kind of error only occurs when the file is opened from within OneDrive for saving in a different folder. In other words, if the file is saved in the same folder, the error won’t pop up but if it is saved in a separate folder, that’s when the error appears. Worry not though for fixing this error is not complicated and won’t take too long. It seems that this error is due to the 259-character limitation when creating and saving files as far as the Office products are concerned. To resolve it, there are several workarounds you can check out. Before you proceed with these workarounds, make sure that you have a stable internet connection.

Option 1 – Try renaming the file with a shorter name

The first thing you can do to fix the problem is to rename the file with a shorter name. Just right-click on the file and select the Rename option from the menu and then type in the new name and click OK or tap Enter to rename the file.

Option 2 – Try renaming the folders where the file is located

Like what you did in the first given option, all it takes is a right-click but this time on a folder. Rename the folder with a different name and save the changes made and then check if you can now save the Word document on OneDrive.

Option 3 – Try moving the file to a folder with a shorter path

If the first two options didn’t work, you can try moving the file to a folder with a shorter path. Note that it is not the same as doing it locally on a Windows 10 computer so you have to right-click on the file and select the “Move to” option. After that, locate the folder where you want to move the file and select it and then click on the Move button to complete the task.

Option 4 – Try making some changes in the document

You could also try to make some modifications to the document. Once you’ve done that, click the File tab and select the Save As option and then go to the folder where you want to save the file and tap enter.

What is SMSFromBrowser

SMSFromBrowser is a Browser Extension developed by MindSpark. This extension usually comes bundled up with other software or via online advertising. Allegedly this extension allows you to send SMS messages from your computer, however, all it does is point you to other websites that offer this service. While active this extension monitors your browsing behavior, it records your website visits, clicks, links, and sometimes even private information, in order to use this data to better serve additional ads. During your browsing sessions, you may encounter additional unwanted ads, sponsored links, and sometimes even pop-up ads. Several anti-virus scanners have detected this extension as a potentially unwanted extension / Browser Hijacker, and due to its privacy mining behavior, it is not recommended to keep it on your computer.

Browser hijackers (sometimes referred to as hijackware) are a kind of malicious software that modifies web browser settings without the computer owner’s knowledge or permission. These hijacks appear to be increasing at an astonishing rate around the world, and they could be actually nefarious and sometimes harmful too. Browser hijackers are capable of doing more than just modifying homepages. These are typically used to force hits to a specific site, manipulating web traffic to generate ad revenue.

How it infects your personal computer

A browser hijacker can be installed on your computer or laptop when you visit an infected site, click on an e-mail attachment, or download something from a file-sharing website. They can be included with toolbars, BHO, add-ons, plug-ins, or browser extensions. Some internet browser hijackers spread in user’s PC by using a deceptive software distribution technique known as “bundling” (often through freeware and shareware). A good example of a notorious browser hijacker is the most recent Chinese malware known as “Fireball”, which has attacked 250 million PCs worldwide. It acts as a hijacker but could be turned into a fully functioning malware downloader afterward. Browser hijackers could interrupt the user’s web surfing experience greatly, keep track of the websites visited by users and steal financial information, cause difficulty in connecting to the web, and eventually create stability problems, making applications and computers freeze.

Removal

Some types of browser hijackers can be effortlessly removed from your PC by deleting malicious applications or any other recently added freeware. Many times, it could be a tough job to discover and get rid of the malicious program because the associated file will be running as part of the operating system process. And there’s no denying the very fact that manual repairs and removal methods can be a difficult job for an amateur computer user.

Next-generation of RAM, DDR5 supposed to hit shelves around late summer or fall in 2021if everything goes as planned. Its goal is to increase speed and efficiency, wants to pack more memory in a single stick, and have better power management.

Hardware requirements for DDR5

Using the latest memory technology will require other hardware to follow certain standards and the first ones that will need to follow are CPUs and Motherboards. Intel is already prepared with its Alder Lake CPUs that suppose to come out also later this year. AMD on other hand has not stated anything at the time of this writing but it is a bet that their next generation that will come in 2022 will have full support. It is speculated that bot companies and their respective CPUs will have both support for DDR4 and DDR5. A story about motherboards is a little different. Motherboards will support DDR4 or DDR5 memory banks, not both, so make sure that your motherboard will support the memory you plan on getting.

Capacity of memory

The goal and aim for the DDR5 memory stick are to reach a whopping 126GB per stack. This will be done by using a dual in-line module or DIMM enabling larger capacity. That being said, the first modules that we will see are more likely to be 16GB as standard and 8GB as low entry ones.

Power consumption of DDR5 memory

The standard voltage that DDR4 operates under is 1.2V. DDR5 wants to lower this to 1.1V without sacrificing speed. Voltage regulation on modules themselves will be now integrated on memory banks instead of leaving that to motherboards which will help to detect memory errors directly on the memory bank.

Speed of memory

The most common speed of DD4 memory banks is 2,666MHz, more expansive ones go from 3,600 to 4,000MHz. DD5 aims to raise this bar to 4,800MHz and offers greater speed.

Should you get it right away?

Hardware is ever-evolving, we have PCIe 3.0 to PCIe 4.0, and taking into account that sometimes the newest tech can cause some unexpected behavior it is always the best strategy to wait for a little. Price for the newest tech has also been in its heist just when it is released and seeing how DDR5 will benefit mostly servers mostly since even today memory, processors, and other available equipment can tackle all daily tasks.

Error Code 40 – What is it?

Error Code 40 is a device driver error that users encounter on any Windows 2000 and later operating systems. It occurs when the peripheral device that you connect to your PC cannot be accessed due to a change in the system registry.

This is due to the presence of invalid sub-keys of the device driver in the system registry. It is a common error that users come across and appears on your PC with either of the following messages:

“Information in the registry entry for this driver is invalid”

OR

"Windows cannot access this hardware because its service key information in the registry is missing or recorded incorrectly. (Code 40)"

Solution

Error Causes

As mentioned above, the error code is triggered when the device driver’s invalid sub-keys appear in the registry, effectively changing it. This happens when the windows system files get damaged due to the following factors:

• An incomplete program uninstallation
• An incomplete program installation
• Hardware is not removed properly
• System recovery from viruses
• An improper system shut down

Factors such as incomplete installations or uninstallations or an improper system shut down can cause files to become damaged that threaten the health of your computer.

Removing viruses from the computer is also another factor as it removes the entries in the Windows system files which contain the viruses including spyware or malware

Further Information and Manual Repair

Fixing Error Code 40 is similar to fixing other device manager error codes. Here are a few methods you can try.

Method 1 – Use System Restore

You can use system restore to eliminate the problem. Here is how you can use it:

• Log in using an Administrator account
• Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
• Click ‘Restore my computer to an earlier time’ and click ‘Next’
• Select the last Windows restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
• Click ‘Next’ on the confirmation window to proceed
• Restart your PC after restoration is complete

By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system registry files that can help avert the error code.

Method 2 – Manually uninstall then reinstall the device driver

If using system restore also does not work in removing the error code, you may have to resort to manually uninstalling and then reinstalling the device driver causing the problem.

This would be necessary since the remaining incomplete files due to a partial removal or installation of programs is what contributes to the error code. By uninstall and reinstalling the device driver program, it would lead to the completion of the files.

You can do this by firstly logging in as Administrator and open Device Manager. Select the device that is causing the problem and double click it and make sure that the peripheral is connected properly to the PC. Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’.

Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.

Method 3 – Use software to automatically download the driver

Manually uninstalling and reinstalling the driver will do the trick, however, it may be time-consuming especially when you would have to resort to your hardware user manual.

Therefore, using a program such as DriverFIX can save you a lot of time and frustration in having your device work properly on your computer.

DriverFIX, with its user-friendly approach to help you fix your PC issues, comes with an integrated database that detects which drivers you need to reconfigure within just a few seconds and downloads it automatically.

It further ensures that your drivers are installed in their entirety leaving no room for any incomplete files to remain that create Error Code 40.

It also has the added advantage of being able to backup and restores your files should there be the slightest possibility of system file damage.

Thus, registry damage can be averted by letting the software roll back the system files to an earlier healthy checkpoint. Driver Assist is the answer to fixing your PC error codes accurately and quickly.
