Solution

Error 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.

Method Two: Disable Firewall Software

Like method one, this manual repair method can be effective in combating issues related to 0xC1900101-0x20017. This is of course, dependent on whether or not the error code is due to an incompatible security program.

Temporarily disable your firewall by adjusting its settings. Once this step is complete, reboot your machine and attempt to install the latest version of Windows 10. If you are able to complete the process, this means the problem was due to an issue with your firewall. You can then enable the firewall you previously disabled or download another program as its replacement.

If the error code reoccurs, however, consider implementing the next manual repair method on this list.

Method Three: Use Command Prompt to Check for Damaged System Files

Command Prompt can be very effective in helping regular as well as technically skilled users repair issues with their PC. In the case of error code 0xC1900101-0x20017 in Windows 10, access Command Prompt using the following instructions.

• Step one: Right-click Start Menu
• 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.

When it comes to booting an operating system on a computer, one of the most essential pieces of software you can use is the UEFI. In fact, a lot of users now prefer to use UEFI instead of BIOS. It also depends on whether the UEFI or the BIOS is supported on the motherboard. Recently, a number of users reported an issue with UEFI where they were unable to find it under the Advanced Options screen where it’s supposed to be located. The missing UEFI Firmware settings in the Advanced Options could be caused by several reasons. It is possible that the access to the UEFI menu is blocked or it could also be due to the Extra Fast Startup feature being enabled. It is also possible that the operating system is installed in Legacy mode. There are several options to try to fix this issue. You need to check if your computer supports UEFI or you could also try to disable Fast Startup or bypass the Extra Fast Startup feature. You can also use a boot to UEFI shortcut as well as check the CMOS battery.

Option 1 – Try checking if your computer supports UEFI

The first thing you have to do is to verify if your computer supports UEFI. If your computer does not support UEFI, then it’s no wonder why you don’t see the UEFI Firmware settings in the Advanced Options.

Option 2 – Try turning off Fast Startup

• First, boot your computer in Safe Mode.
• Once your computer is booted in Safe Mode, tap the Win + R keys to open the Run dialog box and type in “control” to open the Control Panel.
• Next, click on the Hardware and Sound section and click on Power Options.
• Afterward, select the “Choose what the power buttons do” option from the left side menu pane.
• Now click on Change settings that are currently unavailable and uncheck the entry that says, “Turn on fast startup (Recommended)”.
• Then click on Save Changes and restart your computer and see if it has fixed the problem or not.

Option 3 – Try bypassing the Extra Fast Startup feature

As mentioned, the missing UEFI Firmware settings could be due to the Extra Fast Startup feature. To fix it, you have to disable this feature. All you have to do is tap and hold the Shift key and click on the Shutdown button from the Start button. This will boot your PC with the UEFI booting from the beginning and then use the hotkey for your motherboard to boot into the UEFI setup.

Option 4 – Try using a boot to UEFI shortcut

• Right-click on any empty space on your Desktop and select New > Shortcut.
• This will open a new mini window. And here, you have to type this in the text field: shutdown /r /fw
• After that, click on Next and name the desktop shortcut and then click on Finish.
• Next, right-click on the newly created shortcut and select Properties.
• Click on the Advanced button and select the “Run as administrator” option.
• Now click OK to save the changes made. Each time you execute this shortcut, your computer will automatically be booted to the UEFI Firmware Settings.

Option 5 – Try to check the CMOS battery

Another thing you can do is check the CMOS battery physically on the motherboard and see if it has to be replaced since a damaged CMOS battery can also cause the issue with the missing UEFI Firmware settings.

Option 6 – Set your computer from Legacy to UEFI

If applicable, you can try to set your computer from Legacy to UEFI to resolve the problem.

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: mbr2gpt.exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

A newfound bug in Google docs is causing it to crush and upon reopening it will crush again making it very difficult to re-access your document. The bug is manifested when a series of the same word is typed into a document and Show grammar suggestion is turned on.

How was it found

A Google Docs user, Pat Needham brought up the issue on Google Docs Editors Help forum.

"I've only tried in Google Chrome, with documents from three separate Google accounts (personal, G Suite Basic, and work one which might be enterprise). All three experience this same issue".

"It's case-sensitive. So trying with 'and. and. And. and. And.' doesn't cause it to crash."

While Needham publicly reported the bug, it appears that the issue was discovered by Eliza Callahan who was writing a poem novel for her novel using Google Docs.

Needham's findings have also been confirmed by other users running Firefox 99.0.1

Another user, Sergii Dymchenko, said strings like "But. But. But. But. But." triggered the same response. Some also noticed putting any of the terms like "Also, Therefore, And, Anyway, But, Who, Why, Besides, However," in the same format achieved the outcome.

A YCombinator HackerNews reader suspected the cause to be the "Show grammar suggestion" option in Google Docs.

A Google spokesperson confirmed the presence of the issue adding, "we're aware of this issue and the team is working on a fix."

How to recover your document

First thing first, turn off Show grammar suggestions so you do not run into issue by accident. In order to turn it off go to Tools and then into Spelling and grammar and untick Show grammar suggestions.

Now, if you already have a document that has been crushed, fear not because there is a workaround to access it. For some strange reason this bug does not manifest on Google Docs mobile app, so you can open the crushed document in the mobile app, delete words that have caused the bug and reopen the document on your desktop.

Until Google comes up with the solution this is currently the only way to address the issue.

Outlook PST Errors

Problems occur when your PST file becomes corrupted or hits the size limit. Outlook will start to display error messages. These errors include like 0x80040119, 0x80040600, and 0x8004060c.

Error Causes

You might think Outlook problems are just a minor inconvenience. You can’t access your emails and contact information, but that doesn’t actually affect computer security, right? Wrong! Outlook problems can indicate serious corruption issues within your system.

In many cases, your PST file can even be targeted specifically by a virus.

Today, many viruses are specially designed to steal personal information and then sell that information on the online black market. Since so much personal data is stored within Outlook’s PST file, this is often the first place that viruses look.

If you don’t want some hacker in a foreign country to read your emails, steal your contact information, or do all sorts of other dangerous tasks, then we advise you to fix your PST problem as soon as possible.

Other causes include hitting the 2GB memory limit on older versions of Outlook, erroneous SMTP settings, etc,.

Better Alternatives to Microsoft's ScanPST.Exe

Ultimately, after downloading ScanPST.exe and running it, your Microsoft Outlook will still be unable to send or receive emails. And, to make matters worse, you might also be unable to access contact data or read your old emails.

Unlike other PST repair solutions, ScanPST.exe will not recover deleted emails or other lost Outlook data. In fact, using ScanPST.exe can sometimes cause your personal data to become even more difficult to recover.

If you do want to try out ScanPST.exe, then go ahead. While it probably won’t make your PST errors worse, it won’t even come close to fixing them. If you’re ready for a more serious solution to PST problems, then keep reading.

Parallels is an application developer for MAC OS mostly known for its PC virtualization software Parallels Desktop, a PC virtualization software running on Macs enabling running Windows and Linux with respective software on your MAC. With its latest Desktop 17 version, the software can run natively on both Intel-based and M1-based MACs. Thanks to this feature MAC users will be able to benefit from various speed improvements while running both Windows 10 or Windows 11 preview. On both Intel and M1 setups, Parallels resumes Windows and Linux up to 38% faster, provides an up to 25% bump in 2D graphics and a six-time increase in OpenGL graphics processing. M1-centric stats include 33% faster Windows start-up times, up to 28% faster DirectX 11 performance, and up to 20% better disk performance on Windows 10 Insider Preview. Parallels Desktop 17 delivers a set of fresh features including a new video driver that enhances video and game playback and boosts Windows UI responsiveness.

This function works well with MAC OS Monterey's Quick Note feature, which can accept content from any Windows app. USB support, disk management, copy and paste unformatted text, and automatic virtual machine optimization also receive upgrades.

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.
