Fix Windows Sandbox failed to start 0x80070015

Recently, several users reported an issue on their Windows 10 computers where the taskbar is not visible when they tried to connect to a computer via Remote Desktop Protocol or RDP. The Remote Desktop Connection feature uses the RDP which allows users to access a computer remotely. This is actually different from the taskbar being hidden automatically until the pointer hovers on it since, in this scenario, the taskbar is completely not accessible which makes using the remote computer entirely difficult, if not impossible. There are several suggestions you can check out to resolve this problem, you can try to restart the process of Windows Explorer via Task Manager or you could clear the cache for multiple processes. You could also try to reinstall the Shell Experience components or show the local taskbar in the Remote desktop. Moreover, you could also try to update, uninstall or roll back the display driver/graphics card driver. For more details, refer to each one of the options given below.

Option 1 – Try to restart the Windows Explorer process

The first option you have to try to fix the problem with the taskbar is to simply restart the Windows Explorer process in the Task Manager.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Next, go to the Processes tab and find the process of Windows Explorer.
• Once you find it, right-click on it and select Restart to restart its process.
• After that, restart your computer and see if you can now see the Taskbar.

Option 2 – Try clearing the cache of multiple processes

The next thing you can do to resolve the problem is to clear the cache of many processes in your computer. To do so, follow these steps:

• Open the Notepad app and paste the following content in the text area:

@echo off taskkill /f /im explorer.exe taskkill /f /im shellexperiencehost.exe timeout /t 3 /NOBREAK > nul del %localappdata%PackagesMicrosoft.Windows.ShellExperienceHost_cw5n1h2txyewyTempState* /q timeout /t 2 /NOBREAK > nul start explorer @echo on

• After that, tap the Ctrl + S keys to save the changes you’ve made in Notepad and select the “All files” as its file type, and then name it “CacheClearTWC.bat”.
• Next, go to the location where you saved the file using File Explorer and then run it. This will run a couple of batch scripts which will clear the cache of multiple processes in the system.
• Tap the Win + X keys and select the “Windows PowerShell (Admin)” option to open PowerShell as admin.
• Next, execute this command in the command line: Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + “appxmetadataappxbundlemanifest.xml”)}
• After the command has been executed, this will reinstall the Shell Experience components and should fix the problem with the taskbar.

Option 4 – Update, uninstall or rollback the Graphics card drivers

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

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

About Browser Hijackers

Browser hijacking means a malicious program code has power over and modified the settings of your browser, without your permission. Browser hijackers could do more than just changing home pages. In general, hijackers are developed for the benefit of online hackers often through income generation that comes from forced ad mouse clicks and website visits. Nonetheless, it isn’t that harmless. Your web safety is compromised and it is also really annoying. In a much worst case, your browser could be hijacked to download malicious software that will do a great deal of damage to your computer.

Key symptoms that your browser has been hijacked

When your browser is hi-jacked, the following can happen: you notice unauthorized changes to your internet browser’s homepage; you observe new unwanted favorites or bookmarks added, usually directed to advertisement-filled or porn websites; the default browser configurations have been changed and/or your default web engine is altered; unwanted new toolbars are added to your internet browser; you might notice numerous pop-up adverts on your computer screen; your browser has instability issues or exhibits frequent errors; You can’t access particular websites, especially anti-malware websites.

Exactly how they invade computers

A browser hijacker can be installed on your computer or laptop when you go to an infected site, click on an e-mail attachment, or download something from a file-sharing site. Many internet browser hijackings originate from add-on programs, i.e., browser helper objects (BHO), toolbars, or plug-ins added to browsers to provide them additional features. Other times you might have accidentally accepted a browser hijacker as part of a software bundle (generally freeware or shareware). Popular examples of browser hijackers include CoolWebSearch, Conduit, OneWebSearch, Coupon Server, RocketTab, Delta Search, Searchult.com, and Snap.do. Browser hijacking can bring about serious privacy problems and even identity theft, affect your web browsing experience by taking control over outgoing traffic, drastically slows down your computer or laptop by depleting lots of resources, and lead to system instability also.

Browser hijacker removal methods

Some browser hijacking can be easily stopped by identifying and eliminating the corresponding malware software from your control panel. However, most hijackers are quite tenacious and require specialized applications to get rid of them. Moreover, browser hijackers could modify the Windows registry so it can be extremely tough to fix manually, particularly when you are not a tech-savvy person. Browser hijackers can be effectively removed by installing and running an anti-malware application on the affected computer. To get rid of any browser hijacker out of your computer, you could download this particular top-notch malware removal application – SafeBytes Anti-Malware. Together with anti-malware, a PC optimizer software, similar to Total System Care, could help you correct Windows registry errors, remove unwanted toolbars, secure your internet privacy, and stabilize programs installed on your computer.

Find Out How To Install Safebytes Anti-Malware On An Infected Computer system

All malware is bad and the consequences of the damage will vary based on the specific type of malicious software.

If you’re suddenly unable to launch or open Google Chrome or unable to load web pages, then it’s most likely that the files in Chrome have been corrupted or some plugin is taking up a lot of resources which is why you encounter an error message saying, “Google Chrome has stopped working”. And when you try to check the Task Manager, you’ll see that Chrome is really taking up lots of resources, however, when you check the Taskbar, strangely, you will see nothing. If you are currently facing this issue in Chrome on your Windows 10 PC, follow the given options below.

Option 1 – Kill Google Chrome’s process in the Task Manager

If you aren’t able to open Chrome, then maybe its process is running in the background and you don’t see the browser windows. If that’s the case, you may have to force quit the browser and then try to open it again.

• First, right-click on the Taskbar then select the Task Manager. And if the Task Manager is not responding, you can just use the Alt + Ctrl + Del keys and then select the Task Manager.
• After opening the Task Manager, under Processes, look for Google Chrome’s process which would most likely be named “chrome.exe”.
• Right-click on Google Chrome’s process and then select the End task option.
• Now try to open Google Chrome again.

Option 2 – Try checking if your antivirus program is blocking Google Chrome

There are instances when due to false-positive, a security or antivirus program might block Chrome which is why it failed to open properly. Thus, you can just disable the security program temporarily and then check if you can now open Chrome or not.

Option 3 – Delete the User Profile in Chrome

You can also try deleting the User Profile folder in Chrome. To do so, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then copy and paste “%USERPROFILE%AppDataLocalGoogleChromeUser Data” and hit Enter.
• From there, look for a folder named “Default folder” and then copy the folder to another drive as a backup.
• After creating a copy of the folder, delete the Default folder.
• Next, open Google Chrome again and go to Settings > Advanced > Reset.

Option 4 – Disable the Extensions in Chrome

There are instances when issues on a browser are triggered or caused by some problematic extension. To find out which one of your extensions is causing the problem, disable them all first and then enable them back one by one.

• Click on the three-dotted icon for the menu located at the top-right corner of your screen.
• Then click on the More tools option and go to Extensions.
• From there, you will see a list of all the installed extensions in Chrome.
• Disable all these extensions and restart the browser.
• Now enable them back one by one to figure out which one of them is the culprit. You could also remove extensions that you no longer use.

Option 5 – Run the Chrome Cleanup tool

You might also want to try running the Malware Scanner & Cleanup tool in Chrome. This is a built-in tool that can help you get rid of any unwanted pop-ups, banners, ads, unusual startup pages, toolbars, and malware. Thus, it can help you to resolve the issue in Chrome.

Option 6 – Try to reinstall Chrome

If running the Malware Scanner & Cleanup tool in Chrome didn’t work out for you, you can try reinstalling it. To do so, follow these steps:

• Open the Settings app and go to System > Apps & features.
• From there, look for Chrome and uninstall it from your PC.
• Then go to the official website of Google Chrome and download its latest version and install it.

As you know, aside from making computing a lot easier, mouse and touchpad, it also makes computing more efficient and less time-consuming. And so life is unimaginable without these useful devices. However, it is a known fact that you can’t customize these devices since all touchpads and mice come with their own default scrolling direction but worry not for in this post you will be guided on how you can reverse their default scrolling directions. Every user has their own different preferences when it comes to scrolling directions. You might want the scrolling directions to look like the page is being scrolled in the same direction in where you move your fingers over the touchpad or you might prefer it in an inverted way. Reversing the scroll direction for your device’s touchpad is really easy as Windows by default offers this customization. So if you are trying to find a way to reverse the scrolling direction of your mouse, then you have to follow a tricky little method which will be provided in this post. It is apparent from the number of settings the touchpad is available that it has become more customizable. You can configure everything, from its gestures, taps, sensitivity, and even its scrolling direction. And now, if you want to reverse its scrolling direction, here’s what you have to do: Step 1: Tap the Win + I keys to open Settings. Step 2: From there, go to Devices and select Touchpad from the menu. Step 3: Next, look for the Scrolling Direction setting. Step 4: Then click on the drop-down and select your preferred setting.  If you want the same direction scrolling, just select the “Downwards motion scrolls down” option, and if you want the opposite select the other one. After you carry out these steps, the settings will be applied right away and you will see the changes. On the other hand, if you want to change the scrolling direction for your mouse, the procedure is not as simple as it was for the touchpad.

To reverse the scrolling direction for a mouse, refer to these steps:

Step 1: In the Start Search, type “device manager” and click on the appropriate result to open the Device Manager. Step 2: After opening the Device Manager, look for your Mouse under the “Mice and other pointing devices” section. It is mostly listed as an “HID-compliant mouse”. Step 3: Right-click on your mouse and click Properties. Step 4: From there, go to the Details tab and from the drop-down menu, select Device Instance Path. Step 5: Now take note of the value displayed on its value field and then tap the Win + R keys to open the Run dialog box. Step 6: Type in “Regedit” in the field and hit Enter to open the Registry Editor. Step 7: Next, navigate to the following location:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumHID

Step 8: From this folder, you have to start matching the values in the first part of the value you’ve taken note of. Step 9: Open the folder which has the same value and repeat this for the second part of the value. Step 10: Afterwards, click on the Device Parameters and look for a property named “FlipFlopWheel” and invert its value from 0 to 1 or 1 to 0 to reverse the scrolling direction. And then restart your PC to apply the changes made. After you restart your PC, you should see the changes in the scrolling direction of your mouse. Note that you can change the value back to its original value or just use the registry backup to undo the changes you’ve made.

Usually when online service is not working or when something goes wrong online it is DNS, well that is what most of the time is the case. And yes, DNS or Domain Name Server seems to be an issue with Facebook being completely down along with Instagram and wassap. The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP. Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted, "By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform." Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things. Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages: "DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures." Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface. Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally." Technicians on site don't know how to do that and senior network administrators aren't on site. It seems that it will all be down for a couple of more hours before the issue is resolved.

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.

There are times when the Windows Search results do not include what you want to search. However, if you are trying to search for something that’s located on your desktop and Libraries, they would appear right away on the search results. Actually, the issue is not with the search but with the list of files and folders that Windows can index. If you encounter this issue, read on as this post will guide you on how to fix it. The Windows 10 operating system, ever since Windows v1903 was released, offers two kinds of searches – the classic and the enhanced search. You may have to add more folders to the classic search or use the enhanced mode to resolve the issue. In other words, to fix the problem with the Start Menu Search, you can try to enable the Enhanced Mode or add folders to the Class Search or remove the excluded folders, as well as run the Search and Indexing troubleshooter. For more information, refer to each one of the options provided below.

Option 1 – Try to enable the Enhanced Mode

To fix the problem, you have to enable the Enhanced Mode search and configure the folders you want to be indexed. How? Follow these steps:

• First, you have to go to Settings > Search > Searching Windows.
• Next, select the radio button for the Enhanced option.
• After that, select the folders you want the Windows Indexer to exclude from the Enhanced Search mode.

Option 2 – Try to add folders to the Class Search

If you don’t want to enable the Enhanced search mode, then you might want to add folders that are important to you. All you have to do is configure the Search Indexing Options by following these steps:

• Go to Settings > Search > Classic and from there, click on the “Customize search locations” option.
• Next, click on Modify in the pop-up window that appears.
• Then add drives and folders that are important to you. Once the indexing is completed, Windows will be able to find the file and display it in the search results.

Option 3 – Try removing the excluded folders

If you have already enabled the Enhanced mode but your files still don’t appear, then you might want to check out the excluded folder list.

• The first thing you have to do is go to Search and from there, you will find a list of folders under the Excluded folder list.
• Next, click on the excluded folder that you want to remove by clicking on the “Remove Excluded folders” button.
• If you are using the Classic search, you have to check if the index has restrictions on the file type. You can find it in Advanced options > File Types.

Note: If you want to search in Documents, you could also enable the Index Properties and File Contents. This should resolve the problem.

Option 4 – Try to run the Search and Indexing troubleshooter

You might also want to run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings for the Windows Start Search are in place and automatically corrects any issues if the update or software installation has changed the settings. To run it just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter.

If you receive an error code of “0x80073afc” in Windows Defender after you boot your Windows 10 computer or when you try to manually run Windows Defender, then it could be that the Windows Defender files are corrupted.

If you connected headphones to your Windows 10 computer to listen to audio but when you check it in the playback devices, you’re not able to find it, read on as this post will guide you in what you can do to figure out what exactly caused this kind of problem and how you can resolve it. This kind of issue could simply be with the headphone itself or the headphone port or your operating system. So if it turns out that the problem is with the hardware, you might have to replace the components. However, it is recommended that you troubleshoot the problem first before doing that. The most basic thing you can do is to try changing the headphone port, although this can be quite difficult since most computers don’t have any extra port for headphones if your computer has one, then give it a go. If it still didn’t work, follow each one of the options provided below.

Option 1 – Try to run the Playing Audio troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to update the Audio driver

If the error has something to do with software, chances are it might be related to the audio driver – it could be that the newest version of your Windows 10 does not work well with the old version of the driver. This is why you have to update your audio driver to the newest available version.

• Tap the Win + R keys to open the Run dialog box and then type in MSC and tap Enter or click OK to open the Device Manager.

Downloading Windows Updates does not always go smoothly as you can encounter several issues like the “Some updates did not finish downloading, We will keep trying, Error code 0x80246007” error. In fact, this error can also occur on other Windows applications like OneNote. According to security experts, this error happens for many reasons. For one, it could be that the Windows Update database is corrupted. It could also be that there is another process that’s in conflict with the Windows Update components or there might be some issue with the Background Intelligent Transfer Service (BITS). Whichever the cause may be, you can fix it by following the solutions given below.

Option 1 – Delete the contents in the Temporary folder

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

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

Option 2 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like Error code 0x80246007. 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 3 – Try renaming or removing the pending .xml file

The problem might be due to some pending .xml file so you need to rename or remove it. To do so, just go to C:/Windows/WinSxS folder. From there, look for a pending .xml file – you can either rename it or delete it. This will allow the Windows Update to delete any pending tasks and build a new and fresh update check.

Option 4 – Restart the Background Intelligent Transfer Service (BITS)

The Background Intelligent Transfer Service or BITS is a part of the Windows Update service that manages the background download of Windows Update, as well as scans for new updates and so on. Thus, if your Windows Update fails a couple of times, you might want to restart BITS. For you to do that, make sure that you have admin privileges.

• Press the Win + R keys to open the Run dialog box.
• Then type “msc” in the field and hit Enter to open Services.
• After opening Services, look for the Background Intelligent Transfer Service from the list of services and then double click on it to open Properties.
• Next, set the Startup type to Manual and click on the Start button. If it doesn’t help, you can try setting it to Automatic (Delayed) and then reboot your PC.

Option 5 – Run the DISM tool

Running the DISM Tool 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”.

• 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.

Option 6 – Delete the files from the Software Distribution folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

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

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

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

Option 7 – Reset the Catroot2 folder

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

• Type each one of the following commands.

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

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