Solution

Restoro box imageError Causes

There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:

Computer malware has infiltrated your device.

• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.

• When there are mismatched system files installed or system upgrading process failed or still incomplete.

• Premature unloading of Wbemprox.dll

• Newly installed third-party software is not compatible with the operating system.

• There are corrupted, outdated, or incorrectly configured device drivers.

• There’s insufficient space in the system partition. Once the system partition is full, certain errors such as error code 0xc000021a will manifest.

• Windows registry is corrupted or damaged due to a software or system change. This means there are registry entries that are not cleared after uninstalling an application.

Further Information and Manual Repair

In fixing error code 0xc000021a, you might want to try and manually do so. Manual repair methods can give users effective and efficient solutions, addressing the root problems in relation to Windows error codes. Once the manual repair method is correctly implemented, users will be able to resolve issues immediately.
However, there might be instances when a Windows professional is needed. In such cases, seek help from a certified Windows expert or you might want to consider using an automated tool whenever necessary.

Method One: Convert the Drive or Partition from NTFS to GPT

In order to fix Error code 0xc000021a in Windows 10, you might need to convert the partition or drive from NTFS to GPT. See below for the procedure:

Fix CLOCK_WATCHDOG_TIMEOUT in Windows
If you encounter the CLOCK_WATCHDOG_TIMEOUT Blue Screen of Death error while using your Windows 10 computer then it is most likely caused by a specified processor which is not processing interrupts. This occurs when the processor is deadlocked or nonresponsive. Specifically, this kind of Stop error occurs when the processor is having a hard time with the cooperation of its threads and cores. The threads are the tasks performed by cores and some cores can have many threads at the same time. And this is where the problem begins – one thread is waiting for an adequate response from another thread or one kernel is waiting for a response from another kernel and those responses are not coming. In other words, when the processor is unable to continue the processing of tasks since its resources are occupied and are interdependent to get free, such a state is called Deadlock. The CLOCK WATCHDOG TIMEOUT bug check has a value of 0x00000101 which means that an expected clock interrupt on a secondary processor, in a multiprocessor system, was not received within the allocated interval. To troubleshoot the problem, you can check out the possible fixes provided below but before you proceed, make sure that you boot your computer into Safe Mode with Networking only.

Option 1 – Undo or disable overclocking if you have overclocked your system

  • Go to the Start Menu and open Settings.
  • Next, select Update and Security and go to the Recover tab.
  • From there, click on Restart now in Advanced startup. This will restart your computer.
  • Once you’re in the Advanced startup, go to Troubleshoot and then select the Advanced Options.
  • From there, select the UEFU Firmware Settings.
  • Now click on Restart. Once your computer has restarted, it will automatically open BIOS.
  • From the BIOS, go to the Advanced tab and navigate to Performance and then look for Overclocking.
  • Once you’ve found Overclocking, make sure that it is disabled. If it’s not, then disable it and then save the changes made by tapping the F10 key.
  • Start your computer normally and check if the CLOCK_WATCHDOG_TIMEOUT 0x00000101 error is now fixed.

Option 2 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the CLOCK_WATCHDOG_TIMEOUT 0x00000101 Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:
  • Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
  • After that, it will give two options such as:
    • Restart now and check for problems (Recommended)
    • Check for problems the next time I start my computer
  • Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Option 3 – Try to rollback, update or disable drivers

The next thing you can do to fix the CLOCK_WATCHDOG_TIMEOUT 0x00000101 Stop error is to roll back, or update, or disable device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
  • Open the Devices Manager from the Win X Menu.
  • Then locate the device drivers and right-click on them to open the Properties.
  • After that, switch to the Driver tab and click on the Uninstall Device button.
  • Follow the screen option to completely uninstall it.
  • Finally, restart your computer. It will just reinstall the device drivers automatically.
Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 4 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like CLOCK_WATCHDOG_TIMEOUT 0x00000101. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:
  • Tap the Win + I keys to open the Settings panel.
  • Then go to Update & Security > Troubleshoot.
  • From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 5 – Try to disconnect or disable newly installed hardware

In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the CLOCK_WATCHDOG_TIMEOUT Blue Screen error.

Option 6 – Troubleshoot the BSOD error in Clean Boot State

You can also troubleshoot the Blue Screen error in a Clean Boot state. There are times when third-party applications cause BSOD errors. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” check box.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And to configure Windows to use the usual startup, just simply undo the changes.)
  • From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 7 – Try to update the BIOS

Updating the BIOS can help you fix the CLOCK_WATCHDOG_TIMEOUT BSOD error but as you know, 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.
  • After that, you should see the developer and version of the BIOS installed on your PC.
  • Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
  • 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 on your computer.
  • Now restart your computer to apply the changes made.

Malware in Popular CCleaner

On September 18th, 2017, Cisco’s Talos announced that CCleaner, a popular utility with billions of worldwide users, had been compromised by hackers, and was used to unwittingly distribute hidden malware in its installer. Later in the day, Piriform, the publisher of CCleaner, confirmed the problem.

Undetected by all but 1 major antivirus including CCleaner’s own parent company, this occurred for over a month and impacted over 2.7 million users. Users of CCleaner v5.33.6162 and CCleaner Cloud v1.07.3191 for 32-bit Windows are affected. These downloads were live on CCleaner’s official site from August 15th to September 12th, 2017. Anyone who downloaded the program during this time could be affected. The company claims that while the hackers set up the backdoor and many users were impacted, that the perpetrators have been arrested and that the malware never successfully performed its full task and compromised user’s PCs or sent out their data; in the wake of recent security breaches such as Equifax, users are understandably worried. Given the severity of the threat of hacking and data theft, users should take action immediately if they have CCleaner.

Technical Details of CCleaner Malware Injection

First reported by Talos, the malware, which was hidden in the CCleaner installer without the publisher noticing (despite them being owned by Avast, a massive Anti-virus company), modified a core program DLL file to evade detection, and creates several registry keys. Not only were these files not flagged by any major Anti-Virus, but they were also even digitally signed by Piriform via their Symantec certificate, meaning your PC and security program would likely whitelist and trust the malicious installer. The malware gathers personal information on a user’s PC, including IP address and running programs, and sends it to a remote server. In our testing, the program sent data to IP 216.126.225.148.

Restore Your PC (If Possible)

As of the publication of this article, there have been no assurances given that updating or even uninstalling CCleaner will remove the malware is installed. The only action thus far has been shutting down the remote server where user data was being sent has been shut down by authorities. For this reason, it is best to remove the underlying malware separately, as its presence represents a serious security threat. Unfortunately, as this could have been installed as far back as August 15th, 2017, your System Restore points may not go back that far, or even if they do, restoring to such an outdated point may cause unintended problems with other programs you use and potentially lost files and data. Manually backing up files and doing a full format or clean Windows installation would likely be successful in fully removing the malware, but is extremely time-consuming and can be difficult for many PC users. Unfortunately, this makes a PC Restore or format an unattainable option for many.

Update CCleaner to the Latest Version

While CCleaner has told users to update to the latest version of the program. Prior to doing so, we recommend fully uninstall CCleaner, ensuring you check its program files folders and registry keys, manually deleting any remnants, and then re-downloading the latest version from the official site and reinstalling clean.

Change Font Size in Sticky Notes in Windows
Sticky Notes is one of the useful programs and in the early days, the option is available for users to change the font size of the text a lot easier. However, for some unknown reason, Microsoft decided to get rid of this feature in the latest Windows Update. One would expect that the feature will be replaced by an even more useful feature but it’s not which makes the Sticky Notes app worse than before. Worry not though for it doesn’t have to stay that way as there is another thing you can try to change the font size in your Sticky Notes app and that’s what we’re going to cover in this post. As mentioned, Microsoft removing this font feature is quite strange and in the past, users asked for this feature and since it’s no longer available, you can try following the steps given below to bring it back. And for that, you need to go to the Ease of Access section in the Settings app. Refer to the steps given below for more instructions. Step 1: First, tap the Win + I keys to open Settings and then go to the Ease of Access section. Step 2: After going to the Ease of Access menu and select Display from the list of options. Step 3: From there, you should see an option that says “Make text bigger”. And then use your mouse to navigate to the slider to change the size of the font. Note: Take note that after doing all the steps above, it will change not just the Sticky Notes app but also everything in Windows 10. This method is actually the best since it only changes the size of the apps rather than a wholesale change in your Windows 10 computer. Step 4: Next, scroll under Display until you see the “Change the size of apps and text on the main display” option where you’ll see that the option is 100% but you’ll want to change that to 125%. Step 5: After that, click on the drop-down menu and select 125% and then restart your Windows 10 computer. Step 6: Now open the Sticky Notes app and check if you can now change the font size in the Sticky Notes app.

and so on, then your system may be exposed to serious privacy and security threats.

Solution

Restoro box imageError Causes

To begin with, DLL files are shared files, and they can and do exist outside the software applications. While these files do provide benefits to software developers, once they are separated, they can only spell trouble. Hence, you start seeing the HTMLayout error, which will most probably occur at system startup, program startup, or when trying to use specific functions in a program. There are a number of reasons why the HTMLayout errors occur, and some of the common ones include:
  • The file is missing because it was accidentally deleted from the system.
  • The file was damaged by a virus and as a result, your system cannot access it.
  • The file was related to the registry and is now corrupt or obsolete.
  • The program that was related to the file was not uninstalled properly.
  • The file was overwritten by a corrupt or outdated version.
  • The spyware or malware deleted the original file and disguised it as the HTMLayout.

Further Information and Manual Repair

While the HTMLayout DLL error may sound like too much trouble, it is rather easy to resolve with a few steps. If you are getting the error because of a specific program or file, then you should reinstall to make sure the error does not pertain. For that, follow these steps:
  1. Go to Start and select the Control Panel.
  2. Click on the Add/Remove Programs icon and select the programs that show the error on the list.
  3. Select Remove/Uninstall to safely remove the program from your system.
  4. Restart the system and reinstall the program again.
This is the easy way out if the HTMLayout DLL error is occurring as a result of the file missing. However, there can be cases when the file has been tampered with by virus or registry issues.

How to Fix Task Scheduler Error 0x80070057
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.

This Windows error code may occur due to issues with a third-party antivirus program or problems related to a driver or hardware. When this occurs users will receive an error message and their machine will automatically revert to the original operating system on the device. Common symptoms of the error code include the following:

  • Error code 0xC1900101-0x20017 message box
  • Inability to complete Windows 10 upgrade

Solution

Restoro box imageError Causes

Like many other error codes affecting Windows 10 users, 0xC1900101-0x20017 may result due to several different reasons. Oftentimes, error code 0xC1900101 -0x20017 affects users who attempt to upgrade their operating system but have incompatible drivers or hardware as well as antivirus or other security systems which prevent the upgrade from occurring. If this error message is not resolved, it could give birth to other error messages such as error code 0x80070652

Further Information and Manual Repair

To fix this particular error code affecting Windows 10 devices, you will need to employ at least one manual repair method mentioned within this article. Manual repair methods offer effective solutions as they seek to address the root causes related to Windows error codes. When the manual repair methods are implemented correctly, users are usually able to quickly overcome issues that cause Windows error codes and can thereafter access all the benefits Windows has to offer to its users.

Note, however, that in a few cases where technical skills are required, the need for a Windows repair technician may present itself. In such a case, resort to Windows forums and other resources to access help from a certified Windows professional. Also, consider using an automated tool where necessary.

Method One: Temporarily Disable or Uninstall Third-party Security Software

Some third-party security programs or antivirus software may interfere with the installation process when Windows users attempt to upgrade to Windows 10. To verify if this is the issue causing error code 0xC1900101-0x20017 on your device, temporarily uninstall or disable these applications. You may easily do so by checking the settings of these programs or visiting Settings within the Windows Start Menu.

Once you have disabled these programs on your device, reboot your machine and attempt to update to Windows 10. If the issue was caused by a third-party app, error code 0xC1900101-0x20017 will no longer occur and your machine will successfully upgrade to the version of Windows 10 you attempt to download.

However, in the case where error code 0xC1900101-0x20017 in Windows 10 reoccurs during the installation process, you will need to resort to another manual repair method listed below.

  • Step two: Select Command Prompt (Admin)
  • Step three: Type sfc /scannow

Be sure to enter the command as it is written above, with a space between “sfc” and “/scannow”. Wait until the scan is complete. If there are any errors related to system files, i.e. if any system files are damaged, corrupted, or missing, your machine will begin to fix it. Once the process is complete, reboot your PC then reattempt the Windows 10 upgrade process via Windows Update. If you are successful, it means that you have rectified error code 0xC1900101-0x20017. Otherwise, you may need to contact a Windows repair technician.

Method Four: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

But bear in mind that these potential fixes are not that straightforward forward so if you encounter an option you don’t understand much, just skip to the options you have the knowledge of.

Windows SmartScreen can’t be reached right now
SmartScreen is a cloud-based anti-phishing and anti-malware component that’s come packed in all Windows 8 (8.1) and Windows 10 versions. This security component is also used in several browsers and programs like Internet Explorer, Microsoft Edge and Outlook.com. Although this program is quite useful, there’ve been reports that SmartScreen is apparently blocking Microsoft’s own apps from opening. According to some users, they only get the “Windows SmartScreen can’t be reached right now” error message every time they try to open apps from the built-in Windows suite like Photos, Mail, Alarms, Maps, etc. Whenever Windows SmartScreen is either down or unreachable on an end-user PC, your computer won’t be able to download anything in both official and unofficial channels. This error might be due to a corrupted Windows account, or it could be that SmartScreen is disabled from the Windows Defender Security Center or it might be down due to an MS issue. In addition, the error might also be caused by a proxy entry.

Option 1 – Make sure that SmartScreen is enabled

Before anything else, the first thing you must do is to check if SmartScreen is even enabled as it might be the reason why you’re getting the error. You can verify this by simply going to the Windows Defender Security Center. To do so, follow the steps below.
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “ms-settings:windowsdefender” in the field and hit Enter to open the Windows Defender Security Center.
  • After that, click on the Open Windows Defender Security Center button located under Windows Security.
  • Then click on App & browser control.
  • From there, make sure that the Check apps and files toggle is set to Warn and then check the same thing for Microsoft Edge and SmartScreen for Microsoft Store apps.
  • If it turns out that SmartScreen is indeed disabled, you have to restart your computer after making some changes and then check if the issue is fixed upon the next startup.

Option 2 – Check if SmartScreen is down for maintenance

Another possible reason why SmartScreen is not working is that it might be scheduled for maintenance. When SmartScreen is scheduled for maintenance, it will become unreachable for a lot of users at the same time and so before you go over unnecessary troubleshooting steps, you need to verify if SmartScreen is down for maintenance or not.

Option 3 – Try to disable the proxy server

If applicable, you can try to disable the proxy server to fix SmartScreen. There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. In some instances, certain proxy servers can interfere with the SmartScreen component and cause it to become unusable. However, if you are not using a proxy server, just skip this option and proceed to the next one, otherwise, follow the steps below to disable the proxy server.
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “ms-settings:network-proxy” in the field and hit Enter to open the Proxy tab under Settings.
  • After that, scroll down to the Manual proxy setup and make sure that the toggle button of the “Use a proxy server” option is turned off.
  • Now restart your PC and check if the problem is fixed upon the next startup.

Option 4 – Try to create a new Windows user account

There are some users who were able to fix the problem by simply creating a new Windows user account. Although this solution will make you lose a couple of settings enforced through your user account, it’s actually effective in circumventing the “Windows SmartScreen can’t be reached right now” error. To create a new Windows user account, here’s what you have to do:
  • Tap the Win + R keys to open the Run dialog box.
  • And then type “ms-settings:otherusers” in the field and hit Enter to open the Family & other people tab under the Accounts menu.
  • After that, click on the “Add someone else to this PC” option and then click on “I don’t have this person’s sign-in information.
  • Next, insert the user credentials like emails, password, birth date, etc., and then click Next. Take note that if you want to create a new local user account, just click on Add a user without a Microsoft account.
  • After you’re done creating the new Windows user account, click the start icon and then click the account icon and choose to Sign out.
  • After you’re logged in, check if SmartScreen now works properly or not.
