This post will guide you in fixing the “Communication with service process failed” error in Windows 10. This error is related to the Intel Driver and Support Assistant application. Although this error does not reportedly cause any loss of functionality in the computer, however, it still indicates that there is something wrong with some of your driver modules. Intel has taken a bold step and combined its older modules into this new application (Intel Driver and Support Assistant) recently. This application enables users to scan their computers for any available updates from Intel. This is the main application of Intel and provides users a way to update their driver software automatically instead of manually updating it. However, with the recent reports submitted by some users, it seems that something is wrong with this application, and users to have to deal with the “Communication with service process failed” error. This error might be caused by several reasons, for one, it could be that the application is corrupted or incomplete in its nature which is possible since this is still a developing and newly released app. It could also be that there are other utilities or modules that conflict with the Intel software. Whichever the reason may be, you can try out the options given below to resolve the problem but before you proceed, make sure that you have an administrator account as well as an active and stable internet connection.

Option 1 – Disable DSATray in Startup

If you receive this error message every time you start your computer then this means that the application is not able to launch properly. Like pointed out, it could be that it is still incomplete in nature or it conflicts with other applications. Thus, you can try to disable the service from the startup and check if it fixes the problem.

• Tap the Win + R keys to open the Run dialog box.
• Then type “taskmgr” in the field and hit Enter to open the Task Manager.
• After that, go to the Startup tab and look for the Intel Driver and Support Assistant app.
• Right-click on the app and select Disable.
• Restart your PC and check if the error is now fixed or not

Option 2 – Reinstall the Intel Driver and Support Assistant

If the first option did not work, you can try reinstalling the Intel Driver and Support Assistant app. To do so, follow these steps:

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for Intel Driver and Support Assistant and select it and then uninstall it.
• After you have the app uninstalled, open your browser and go to Intel’s official website. From there, download the driver utility manually.
• Once the download is finished, right-click on it and select “Run as administrator” and install the app on your PC with elevated access.
• Restart your PC and then check if the error is now fixed.

The error 0x0000001 also known as APC_INDEX_MISMATCH is one of the fatal errors that users encounter upon starting their computers. This error appears when there is a sequence mismatch in the driver or system file when it is disabling or re-enabling Asynchronous procedure calls. The mismatch happens maybe because of a virus or malware attack, not shutting down your computer properly and incomplete installation of the system files. There are many ways to fix this error. The easiest way is to download a repair utility program. The use of these programs perfectly fits those that are not so technical. All you have to do is download the program and install it on your computer. As soon as it is installed, the program will now scan and diagnose your computer for any errors. After it identifies the errors, it will then repair your PC through either manual or automatic tools. To those who are techie and enjoy the manual resolution, you may take advantage of Microsoft’s analyze debug extension which tells you the cause of the error. After determining the cause then you can now start fixing the error. Check if Hardware is functioning properly. If the cause is due to a hardware malfunction, you will have to make sure that all the pieces you are using are working. All the wires should be attached to their respective ports. Not only that, but you also must make sure that before installing the hardware, it is compatible with the Windows version that is installed into your computer. Use Compatible software. If the problem was caused by software or a driver, you can uninstall and reinstall it. Always make it a rule that whenever you install a program or new software to your computer, make sure it is compatible with your operating system and never skip a step during the installation process. You also have to see to it that the program you are installing does not contain any viruses, malware, or spyware that can be harmful to your computer. Update your Drivers Regularly. In most cases though, the cause of the APC_INDEX_MISMATCH error are outdated device drivers. To resolve this, you will have to go to your Control Panel then look for Device Manager. As soon as you are in the Device Manager window, you can now see the different devices running on your computer. You right-click on each device and check the Properties.  In the Properties window, click on the Driver Tab and look for the date when it was last updated. You can then go to the manufacturer’s website and compare the dates. For a new Windows operating system, you no longer have to go to the manufacturer's website though. All you have to do is click on Update Driver and it will automatically search for updates online. Use a Genuine Operating System. There are also cases where the 0x0000001 error won’t allow you to access your computer. In this case, we have to suspect that the problem could be in your Operating system. To resolve this, you can reinstall your Operating System or update your current operating system. Only use a genuine licensed Windows Operating System because this will not only protect you from Malware and Viruses but it allows you to get all the recent update available from Microsoft. Update your Windows 10 regularly by going to Settings > Windows Update > Check for Updates. You may also turn on the Automatic Update by going to the Advanced options is found on the Windows Update Page. You can always get help online but it really helps to know the basics and determining the root cause of the error.

What is Search.schooldozer.com? And how does it function?

Search.schooldozer.com is a browser extension that functions as a search engine. It is developed and maintained by “Schooldozer”. It claims to improve users’ browsing experience by providing them with improved search results. However, it does not really do the things it claims to do. In fact, they’re quite the opposite ones – instead of improving the browsing experience, it makes users’ browsing experience unsafe and full of sponsored content.

If you suddenly find your Windows 10 computer stuck on the “Preparing to configure” screen for quite a long time now after you run Windows Update, read on as you will be guided on how you can fix that issue in this post. During an update process, there’s a lot of things that go on in the background which is why Windows Updates take quite a while before it finishes. It can be at 25%, 50%, or even 100% but the only message you’re going to see on your screen is the “Preparing to configure Windows, Don’t turn off your computer”. However, if you notice that the Windows Update is taking a longer time than it’s supposed to, the first option is to wait some more but if it’s still the same, then there’s definitely something wrong. This kind of issue occurs when Windows Update fails to configure in short correctly download and install the update. When this happens, it will revert all the changes which are why you were advised to wait for a couple of hours. There are two possibilities why your computer is stuck on the “Preparing to configure Windows, Don’t turn off your computer” screen. The first one is that the Windows 10 operating system is installing any updates. The second one is when the user profile takes time to load or encounters an error. There are several options you can try to fix the problem. You can try running System Restore or boot your computer in Safe Mode or repair the corrupted profile via Registry Editor. You might also want to try using installation media to boot and repair your computer if the other options didn’t work.

Option 1 – Perform System Restore

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Note: If you can’t boot into the desktop of your computer, you can run System Restore in the Advanced Startup Options by following these steps:

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.
• Once it’s done, restart your computer.

Option 2 – Boot your computer in Safe Mode

You can try to tap the F8 key if you have it enabled in your Windows 10 computer, as you start your system to boot into Safe Mode. Once your computer is in Safe Mode, you can access the Start Menu and the Mouse and Keyboard. Aside from that, you can also access your files and other built-in tools in Windows such as Command Prompt, PowerShell, Computer Manager, Device Manager, Event Log Viewer, and many more. On the other hand, if you haven’t enabled the F8 key, you can just go to the Advanced Startup options to boot your computer into Safe Mode. Once you’re there, select Troubleshoot > Advanced Options > Startup Settings > Restart > Tap the number 4 key. After that, your computer will restart in Safe Mode. If you want to reboot into Safe Mode with Networking instead, you can tap the number 5 key and for Safe Mode with Command Prompt, tap the number 6 key. Once your computer is in Safe Mode, you can use any of the built-in tools to restore your computer or troubleshoot the problem that’s causing your computer to get stuck at the “Preparing to configure” screen.

Option 3 – Try to repair your corrupted profile via Registry

In this third option, you can try to repair the corrupted profile using the Registry but before you proceed, take note that you can only try this if you can boot into your desktop and if you can, make sure to create a System Restore Point and then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter or click OK to open the Registry Editor.
• Next, go to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
• Once you’ve opened the registry key, you should see a list of all the user profiles on your computer. Now click on each S-1-5 folder and look for the “ProfileImagePath” entry and double click on it to check which user account it is related to. You will see a path like “CUsersACK” where “ACK” is the username.
• You should know which of the user account is corrupted. Just look for a key named “RefCount” and change its Value data to “0” and click OK. And if it isn’t available, simply right-click on the right pane and create it.
• After that, double click on the key named “State” and make sure that the Value data is “0” and click OK.
• Exit the Registry Editor and restart your computer to apply the changes made.

Option 4 – Try to use installation media to boot and repair your computer

Another thing you can try to resolve the issue is to use the Windows installation bootable media so you can boot and repair the operating system. To use it, follow these steps:

• You need to first create an installation media which has the dame version of the operating system installed in your computer.
• After that, once you reach the Install Windows screen, click on the “Repair your computer” link.
• Wait until the repair is completed and then shut down your computer
• Now once your computer has restarted, check if it can now boot properly.

There are times when system files get corrupted and if the Windows Update process finds the system’s integrity questionable, chances are, the update, upgrade or the installation may fail and you will only be getting an error code 0x80073712 instead of completing the process. The error code 0x80073712 indicates that a file needed by the Windows setup or the Windows Update is most likely missing or damaged. To resolve the problem, here are some suggestions you can try.

Option 1 – Try running 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 as admin.
• Then type in this command: 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.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 2 – Try running the System File Checker

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 causing the error 0x80073712. 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.

Option 3 – Try running the Chkdsk utility

You can also try running the Chkdsk utility to resolve the Windows Update error 0x80073712. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
• chkdsk C: /r /x
• chkdsk C: /f

Note: The Chkdsk function might take a while before it finishes its operations so you need to be patient and wait until the entire process is completed.

Option 4 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. 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.

Option 5 – Try running Microsoft’s online troubleshooter

You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors.

One of the important functions in the Windows operating system is the Task Scheduler. It can automatically run various tasks at a certain time where you’ll have to add a task that needs to be executed and then choose the time it has to run at. So when that time comes, the Task Scheduler will run the task automatically. However, some users reported getting an Error 0x80070057 where the Task Scheduler fails to start. This kind of error may be due to a disabled service that prevents the service from running. It is also possible that the antivirus program interfered with the task – it could be that the Task Scheduler is somewhat in the block list since the antivirus adds it to the list automatically when it’s installed. On the other hand, it could be that you lack administrator-level privilege which is why the Task Scheduler was not able to carry out the task. To fix this issue, here are some suggestions you can try.

Option 1 – Try to restart the Task Scheduler service

As mentioned, it is possible that the Task Scheduler service could be disabled. You could have disabled it when trying to enhance your computer’s performance and whatnot. Thus, you need to verify if it’s running or not and then restart it.

• First, you need to tap the Win + R keys on your keyboard to open the Run dialog box.
• Next, type “services.msc” in the field and click OK or tap Enter to open the Windows Services Manager.
• You will see a list of Services and from there, look for the Task Scheduler service and double click on it.
• After that, go to the General tab and click on the Startup Type options and then select “Automatically” from the given list.
• Click on the “RUN” option and select the “Restart the Service” option.
• And click on the “After Second Failure” option and then select the “Restart-Service” option again.
• Now click on the “After Subsequent Failures” tab and select the “Restart the Service” option.
• Finally, click on the Apply and OK buttons and then run the Task Scheduler and see if the issue is now fixed.

Option 2 – Try to temporarily disable the anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed in your computer. Thus, disabling them or any security software installed on your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like the Task Scheduler Error 0x80070057 due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program for the meantime and check if it fixes the error or not.

Option 3 – Run the Task Scheduler with an administrator account

Like pointed out, the Task Scheduler Error 0x80070057 may be due to the lack of admin privileges. Thus, you have to log in to an administrator account and try running the Task Scheduler again. It is also recommended that the administrator account you’re going to use as a password when logging in.

Option 4 – Repair the Task Scheduler by deleting corrupted tasks

Note that a single corrupted file can cause big problems so this option is quite important. And for you to delete a corrupted task or any task from the Task Scheduler, you have to use the Registry Editor if you are not able to use the Task Scheduler interface. To do so, follow these steps:

• Tap the Win + R keys to open the dialog box for Run.
• Next, type in Regedit and click on OK or tap Enter to open the Registry Editor.
• Then navigate to this path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTree

Note: In this path, you can see all the tasks that are currently set in the Task Scheduler. And since it would be hard to tell which one of them is corrupted, you have to delete the latest one in Task Scheduler last. But before you do so, make sure that you take note of the ID of the tasks. And for you to get the ID, you have to select the task you wish to delete and double click on the ID string located on your right-hand side, and then copy it in the Notepad.

• Right-click on the task name and then delete it.
• After that, delete the very same GUID which you have copied earlier from these folders:
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheBoot
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheLogon
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheMaintenance
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCachePlain
• ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTasks

Note: You might not see the same GUID from these folders but if you see it, delete it right away.

• Next, navigate to this location: C:/Windows/System32/Tasks
• Delete the very same tasks you just deleted from the Registry Editor.
• Restart your PC and check if the Task Scheduler is back to its normal state or not.

One of the errors you can encounter while browsing the web using your Google Chrome browser is the ERR_TUNNEL_CONNECTION_FAILED error.

Option 2 – Try to reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the ERR_TUNNEL_CONNECTION_FAILED error. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 3 – Try using a VPN connection

There are instances when the network that your computer is logged on might have blocked your access to the website you are trying to open and so to fix it, you can try to use a VPN connection. Once you’ve connected using VPN, try to open the website again and see if you can now access it.

Option 4 – Try clearing browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_TUNNEL_CONNECTION_FAILED. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.
