How to Fix Backup Error 0x80070002

What is OpenCandy?

OpenCandy is an application that downloads and installs software, including other Internet Browsers to a computer system. Used as a bundle, this application installs additional programs that you may knowingly or unknowingly agree to install. Since most users don’t accept the challenge of reading the EULA in its entirety, they tend to download bundled applications unknowingly.

Assessment of OpenCandy PUP

During the initial assessment of OpenCandy, I was a little skeptical about what to look out for or expect. In fact, I had to install the OpenCandy.exe file twice to discern its behavior. I’m not sure how this application got its name but I do believe it has something to do with the fact that it supposedly helps Internet users open a new world of Internet browsing. That conclusion was arrived at after realizing that OpenCandy.exe installed mostly Internet browsers along with a tune-up tool on the test computer. However, as a result of the system requirements, there was a pop-up message indicating that Internet Explorer 8 was not compatible with the computer system in question. In comparison to the malware I’ve encountered since I started researching malware, OpenCandy is everything but malicious. In fact, this application is only categorized as malware because of its’ subtle covert nature of installing bundled programs unsolicited by the user. Additionally, OpenCandy coerces users into changing their Internet Browsers by installing those unrequested by the user. In fact, it’s no shock that OpenCandy chose to install the Internet Browser ‘Opera’ as a part of this bundle since it’s one of the least used browsers according to the Federal Government. Clearly, this was a smoothly disguised advertisement or promotion to force users into using the Opera Browser, along with Internet Explorer 8.0. While these aforementioned browsers in themselves aren’t malicious and are in no way considered malware, they were installed as a promotional tool and without the request of the user. Despite being mentioned within the EULA, advertisers are capitalizing on this since most users do not bother to read the agreements when installing a program. Furthermore, OpenCandy, like most other bundled applications I’ve dealt with, threw in a tune-up tool as a part of the promotion. I found this tune-up application annoying since I had to hassle my way into getting it to close from the computer screen. I can only imagine the hassle users would go through trying to remove this software. Image 7: Depiction of a scan performed by Tuneup Utilities. The scan detected that several areas on the test PC could be optimized/tuned up. Image 8: After a scan was completed using the Tuneup utility program, I was given an option to buy the full version. Nothing is wrong with this marketing strategy. In fact, most utility tools if not all will scan your computer to detect threats or loopholes, but they won't exactly allow you to fix those problems unless you buy the full version. It's not unfair, it's just business. Programs installed during the installation of OpenCandy include:

• Web Companion: Developed by Lavasoft, Web Companion is said to be an application that serves as a security defense for your Internet browsers by preventing unauthorized changes (see image below)
• Tuneup Utilities: Tuneup Utilities does exactly as it says. It cleans up a computer system, whereby preventing unused programs from slowing it down.
• Opera Stable 30.01.1835.88: Opera is a fast, simple, and effective Internet browser that allows users to get around on the web.

All in all, the intent of installing an application such as OpenCandy is to unleash a world of promotion or advertisements on your computer. They are pretty annoying and in some cases difficult to remove. Furthermore, as a user, you want to control what gets installed on your computer without being dictated to or coerced in some EULA that you probably overlook.

Microsoft store is ready and prepared for Windows 11 official release on October 5^th and it is coming with some surprises. It has officially confirmed that many open source and free applications will be in it like Opera, VLC, discord, Libre office, etc. It seems that Microsoft wants to place its store as one place to go for all of your software needs. Another great surprise is the coming of Epic games store implementation. It was officially confirmed but not explained in detail, will we have Epic store opened in Windows store or we will only get installer as a package we will see but this is some great news. As for how it states now, it seems that the Windows store aims to eliminate searching the web for applications and bring them all into one environment with reviews and ratings so you know which one to install and use. It also features a great search engine to find proper applications for your needs. The new store will come to Windows 10 as well but after all Windows 11 has been mostly released and adopted. So expect it via update in two or three months' time. It would be great if some larger companies decide to join MS stores like Autodesk, Adobe, the Foundry, etc so you can install everything you need from it but one can only hope.

As you know, networks that are domain-based are common in organizations and companies. These domain-based networks require multiple computers to be controlled through a single node known as a server. And the one that sets certain policies and restrictions on every system that is joined to the domain is the server administrator. So if you want to add your computer to a domain, you need to have the following information available:

• The domain name
• A user account name that’s registered in the active directory associated with the server
• Windows Enterprise, Pro, or education version

In this post, you will be guided on how you can join or remove a domain. To get started, follow the given instructions below.

Option 1 – Joining a domain

• First, you need to connect your computer to the network associated with the server since your computer and the server have to be on the same network.
• Next, click the Start button and then click on the gear-like icon for Settings to open it.
• After that, navigate to this path: Accounts > Access work or school.
• Then click on Connect. This will open a new dialog box and from there, select the “Join this device to a local Active Directory domain” option.
• Afterward, you will be asked to enter the username and password of your domain account.
• Now select your Account type and when you proceed, you have to restart your computer. Your domain account should now be created.

Option 2 – Removing a domain

• You need to open the Windows 10 Settings app.
• And from there, go to this path: Accounts > Access work and school.
• Next, select the account you want to remove from the domain and then click on Disconnect.
• A prompt will then appear that says, “Are you sure you want to remove this account? This will remove your access to resources like email, apps, network, and all content associated with it. Your organization might also remove some data stored on this device”. Just click on Yes.
• This will give you a Disconnect from the organization prompt.
• Now click on Disconnect and select Restart now to restart your computer. This will complete the removal process of the domain.

One of the essential parts of the Windows 10 operating system is the Microsoft Store as it is the distribution hub of numerous applications such as Netflix, Facebook, and many more. In fact, Microsoft is planning to make it a hub not just for UWP applications but also Windows Classic applications. Microsoft has already built a bridge with the power of Project Centennial which allows developers to migrate and upload their Windows Classic applications to the Microsoft Store. Although the Microsoft Store has been constantly improving, there are still times when you might face an error while using it. One of these errors is error 0x80131500. When you encounter this error, you will get the following error message on your screen:

“Try that again, Something happened at our end, Waiting a bit might help, The error code is 0x80131500 in case you need it.”

To fix this error, you can try changing your internet connection, toggle the date & time settings, change DNS, create a new user account, run the Microsoft Store Apps troubleshooter or reset the Microsoft Store as well re-register it using Windows PowerShell.

Option 1 – Try changing your internet connection

The first thing you can do is to change your internet connection. If you are using Ethernet, you can try to connect to a Wi-Fi connection instead and see if it helps.

Option 2 – Try to toggle the Date and Time settings

The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the error 0x80131500. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.

• Start by tapping the Win + I keys to open the Windows Settings.
• Next, go to Time & Language > Date & time.
• From there, turn the toggle on for the “Set time automatically and Set time zone automatically” option on the right-side panel.
• After that, click on Region & language located on the left side panel and make sure that the Country or region on the right-side panel is set to the country you live in.
• Now close the Settings app and restart your computer and see if it fixes the problem or not.

Option 3 – Try to change the DNS Server

In this option, you can try changing your current DNS settings to the Google Public DNS as it could also help in fixing error 0x80131500. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 4 – Try to create a new Administrator User account

If you have a standard account, you can try creating a new account but this time, you create an administrator user account and then see if the error is fixed or not. Note that you have to sign in with your main account before you can create an admin account.

Option 5 – Run the Microsoft Store Apps troubleshooter

The Microsoft Store Apps Troubleshooter will help you in fixing the error 0x80131500. This is a great built-in tool from Microsoft that helps users fix any app installation issues. So this is worth a try to solve the problem. This built-in tool also helps you fix the Windows 10 Store if it isn’t working. To use the Windows Store Troubleshooter, follow the steps below.

1. Tap Win + I keys again to open the Windows Settings panel.
2. Go to Update & Security and then go to Troubleshoot.
3. On your right-hand side, scroll down to find the Windows Store Apps and then click on the Run the troubleshooter option and see if it fixes the problem.

Option 6 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again and then try to install your app or update your computer again.

Option 7 – Try to re-register the Microsoft Store app via PowerShell

• Tap the Win + X key combination or right-click on the Start button and click on the Windows PowerShell (Admin) option.
• If a User Account Control or UAC prompt appears, just click on Yes to proceed and open the Windows PowerShell window.
• Next, type in or copy-paste the following command to re-register the Microsoft Store app and tap Enter:

powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRootWinStoreAppxManifest.xml

• Wait for the process to be completed and then restart your computer.

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.

Option 6 – Try updating the BIOS

As you know, the BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.

• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version in your computer.
• Now restart your computer to apply the changes made.

Option 7 – Try resetting Windows 10

To fix this BSOD error, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files.

About Adware

Exactly what is Adware? If you have ever owned a computer, then you’ve probably heard the word numerous times, but it is still beneficial to define it. The term “adware” is actually a short form of advertising-supported software and it includes programs that are solely designed to display ads on a computer. A kind of malware, it will come bundled right in with the software package that a user either installs or accesses. Shareware or freeware programs are often times packaged with adware. If adware penetrates your system without you knowing and sends information about you or your PC to 3rd parties, then it is spyware. Quite often, adware changes your web browser settings to open pop-up adverts or modifies browser homepage and default internet search engine to some unwanted website. Adware is a common problem that affects a large number of PCs around the globe. If your computer doesn’t have any anti-malware software then it’s very likely it could get infected with adware as well as other malware.

Adware and its effects on your PC:

Adware could generate and display plenty of ads of all sorts which in turn disrupt the functions of your personal computer while browsing the net. Pop-ups might also show up on your computer’s desktop even when you’re not online. Adware results in a reduction of available memory and processing power, or resources. It also causes a slow net connection because adware consumes bandwidth whenever it retrieves adverts from the internet. Adware was originally created to support companies to generate income when they offer the software away free of charge. However, adware nowadays displays hundreds of adverts which will cause your PC to slow down and even crash.

Adware prevention:

As we discussed, adware could potentially be harmful to your computer, generally not by itself, but by bringing other problems to you. A top-quality antivirus program has the capability of permanently removing adware. We recommend Safebytes Anti-Malware, one of the top-rated anti-malware programs by world-renowned industry experts. It will act either as a preventative tool stopping websites or software installations that contain adware or as a removal tool for an already infected computer. To prevent adware, download software from websites that you trust. Never download from websites that you have never been aware of or tried before; Always study the end-user license agreement (EULA) of any application you want to install; You need to avoid freeware and shareware where possible; Lastly, watch out for ActiveX, since many adware and spyware companies make use of the technology to install their wares onto your computer system

Malware Blocking Internet And All Anti-Malware Software? Do This!

All malware is bad and the consequences of the damage will vary based on the specific type of malware. Some malware variants alter browser settings by adding a proxy server or modify the PC’s DNS settings. In these instances, you will be unable to visit some or all internet sites, and thus not able to download or install the required security software to eliminate the malware. So what to do when malicious software prevents you from downloading or installing Anti-Malware? There are a few options you could try to get around with this problem.

Remove viruses in Safe Mode

In Safe Mode, you can actually change Windows settings, un-install or install some program, and eliminate hard-to-delete viruses and malware. If the malware is blocking access to the internet and affecting the computer, launching it in Safe Mode will let you download antivirus and run a diagnostic scan while limiting possible damage. To enter into Safe Mode or Safe Mode with Networking, press the F8 key while the PC is starting up or run MSConfig and look for the “Safe Boot” options under the “Boot” tab. Once you’re in safe mode, you can attempt to install your anti-malware program without the hindrance of the malicious software. At this point, you could run the anti-malware scan to eliminate viruses and malware without hindrance from another application.

Switch over to an alternate browser

Some malware only targets certain browsers. If this sounds like your case, use another web browser as it could circumvent the malware. If you suspect that your Internet Explorer has been hijacked by malware or otherwise compromised by hackers, the ideal approach is to switch over to a different internet browser like Firefox, Chrome, or Safari to download your chosen computer security software – Safebytes Anti-Malware.

Create a portable USB antivirus for eliminating malware

Another solution is to make a portable antivirus program on your USB flash drive. Adopt these measures to run the anti-malware on the affected computer system. 1) Download the anti-malware program on a virus-free PC. 2) Connect the flash drive to a USB slot on the clean computer. 3) Run the setup program by double-clicking the executable file of the downloaded software, which has a .exe file format. 4) Select the flash drive as the destination for saving the software file. Follow the directions to complete the installation process. 5) Transfer the pen drive from the clean computer to the infected computer. 6) Double-click the Safebytes Anti-malware icon on the thumb drive to run the software. 7) Hit the “Scan Now” button to start the virus scan.

There are times when the Windows Search doesn’t work and you wouldn’t have a clue as to why it happened since it does not give any error codes. In such cases, you have to check the error logs in the Event Viewer to find out more about the problem. From there, look for an error with the Event ID 3104 in the Windows error logs and if you see an error message that says, “Enumerating user sessions to generate filter pools failed”, read on as this post will guide you in fixing the problem. Apart from the error message, you might also see more information in the details section of the log that says, “(HRESULT: 0x80040210) (0x80040210)”. This kind of error is most likely caused by something that prohibits the search function from initializing. A lot of users assumed that it could be due to Cortana but it’s actually not. While some users also reported that they encounter the issue after they restarted their computers. This error was also reported with the same event ID 3104 on the Windows Server. According to security researchers, this error could be caused by problems in the Registry entry of Windows search. It could also be due to an issue with the SYSTEM account where it hasn’t been added to the DCOM Security. It is also possible that the Windows Search function has not been initialized. To fix this error, you can try to rebuild the Search Index manually or run the Search and Indexing troubleshooter. You can also check the startup type of the Windows Search service or try some registry tweak.

Option 1 – Try to rebuild the Search Index manually

The first thing you can do to fix the problem is to manually rebuild the Search Index. You can do that by going to Control Panel > Indexing Options and from there, click on Advanced. After that, go to the Index Settings tab and then click on Rebuild > OK. Once you’re done, check if it fixed the problem.

Option 2 – Try running the Search and Indexing troubleshooter

You could also run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings are in place and automatically corrects any issues with the Windows 10 search function. To run this troubleshooter, just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter. Once the troubleshooter is done, restart your computer and see if it fixed the error.

Option 3 – Try checking the startup type of the Windows Search Service

In this option, you have to check the startup type of the Windows Search service since the service won’t start. To do so, refer to these steps:

• Tap the Win + R keys to open the Run utility and type “services.msc” in the field and then tap Enter to open the Services Manager.
• Next, from the list of services, look for the Windows Search Service or WSearch. Once you find it, right-click on it and select Properties.
• After that, change the Startup type to Automatic and click on the Start button if the service is in the Stop state.
• Now click on the Apply and OK buttons to save the changes made and then restart your computer.

Option 4 – Try changing the Registry entry for Windows Search

Before you apply some registry tweak, you need to create a System Restore point first. Once you have that covered, follow these steps:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor.
• If a User Account Control prompt appears, just click Yes to proceed.
• After opening the Registry Editor, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Search
• From there, click on Windows Search and look for the key named “SetupCompletedSuccessfully” and change its value to “0”. Just right-click on it and select Modify.
• Then input “0” as its value data and click on OK to save the changes made.
• Exit the Registry Editor and restart your computer.
• Now check if the Enumerating user sessions to generate filter pools failed is fixed or not.

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.
