Error Code 0xC1900101, 0x4000D - What Is It?

Error Code 0xC1900101, 0x4000D is not very common among the many error codes emerging when updating to Windows 10. It is specific to Windows 7 users who try to upgrade to Windows 10 system.

This error hinders Windows 7 users to install the Windows 10 update. Once the update is launched, the process will go smoothly until a certain percentage (normally upon hitting 70% or more) and then it gets stuck. The user will then see a notification stating: “The installation failed in the SECOND_BOOT phase with an error during MIGRATE_DATA operation.”

You’ll be able to get past the error after a while. The error message will disappear and continue with the configuration process. But, not for long as it will reoccur at around 90% of installation with another error message saying: “The installation failed in the SECOND_BOOT phase with an error during PRE_OOBE operation.”

How to Fix PFN_LIST_CORRUPT Error on Windows
If you suddenly encounter PFN_LIST_CORRUPT Blue Screen of Death error while using your computer then it means that the Page Frame Number or PFN list is corrupted. Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help. Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PFN_LIST_CORRUPT. 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 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:
  • 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.
  • Restart your computer after the scan is completed.

Option 3 – Check for any hard disk errors

  • On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
  • Next, click on Disk Management on the left side panel.
  • From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.
You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. 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 following command and hit Enter:
chkdsk /f /r
  • Wait for the process to be completed and then restart your computer.

Option 4 – Update the Device drivers

Updating the Device drivers can also help you fix the PFN_LIST_CORRUPT Blue Screen error. To do so, follow the steps below.
  • Tap the Win + R keys to launch Run.
  • Type in devmgmt.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. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
  • Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
  • Restart your PC and then check if the Blue Screen error is now fixed or not.

Option 5 – Disable OneDrive

The PFN_LIST_CORRUPT error might also be caused by OneDrive. Thus, you have to try disabling this program to resolve the problem.
  • Tap the Ctrl + Shift + Esc keys to open the Task Manager.
  • Once the Task Manager is open, click on More Details located at the bottom left portion of the window.
  • Then go to the Startup tab and select Microsoft OneDrive and then click Disable.

Attempt was made to reference a token
If you were trying to open File Explorer but it suddenly stopped working and you encounter an error message that states, “An attempt was made to reference a token that does not exist”, read on as this post will guide you in fixing this problem. This problem was initially reported after the April Update and Microsoft was able to fix it right after correcting the build. However, this effort seems futile for some users as recently, some reported getting the same error when they try to open not just Windows File Explorer but also with utilities like Microsoft Management Console or MMC, Visual Studio, Task Manager, Printer, Recycle Bin, etc. Two of the most likely causes of this error are a troublesome Windows Update and corrupted system files. Whatever the cause is, here are some suggestions you can follow to fix the “An attempt was made to reference a token that does not exist” error.

Option 1 – Try to re-register the problematic DLL file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.
  • Open Command Prompt as admin from the WinX menu.
  • Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
    • exe /[DLL file]
    • exe [DLL file]
Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.
  • After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Replace the DLL file from a trusted source

  • First, you need to get the new DLL file from another computer with preferably the same file version number.
  • After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
    • x86: This PC > C:/Windows/System32
    • x64: This PC > C:/Windows/SysWOW64
  • Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
  • Now type the “regsvr32 ntdll.dll” command and hit Enter.
  • Restart your PC and check if the error is now fixed.

Option 3 – Perform a System File Checker scan

The System File Checker or SFC scan could detect and automatically repair damaged system files that could be causing the “An attempt was made to reference a token that does not exist” error to pop up. 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. 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 and hit Enter.
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 4 – Try reverting back to the previous build of Windows

This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.

For instance, this error might pop up when you click the audio icon from the system tray or when the Windows Upgrade or Update has failed. Needless to say, this error can be caused by different factors. Anyhow, this post will show you what you can do to fix the problem when the error pops up during a Windows Update or Upgrade. If you are seeing this error when you try to install the latest Windows updates, it will show a Windows Update failed message and you obviously won’t be able to update your Windows 10 PC until you fix this error. You will keep seeing this error even when you try to reboot or update it a couple of times. As mentioned, the error code 0x800706be appears when there is something wrong with your system files – they are either corrupted or misconfigured.

USB keep disconnecting and reconnecting
If your USB keeps disconnecting and reconnecting after you connect your USB device on its own randomly, then the problem might have something to do with a hardware or driver issue. The first thing you have to do in such a case is to make sure that the device is working on another computer. This will help you isolate the problem and if it turns out that it works, then the problem lies in your computer and not your USB device. To fix this connection problem between your USB device and Windows 10 computer, you can use the options given below as a reference.

Option 1 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:
  • First, click the Start button and type “device manager”.
  • Then click on the “Device Manager” from the search results to open it.
  • From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.
  • Restart your PC and then click the “Search automatically for updated driver software” option.
Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 2 – Try to change the USB port

You might want to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it.

Option 3 – Try to turn off the Power Saving option

You could also try to turn off the Power Saving option to resolve the problem. All you have to do is switch to Power Management after you select the Properties of the USB device and from there, uncheck the “Allow the computer to turn off the device to save power” option. On the other hand, if you are using a laptop and did not use the USB device for a long time, then it could be powered off. This will ensure that the system does not turn off the USB device.

Option 4 – Try to reinstall the latest Universal Serial Bus controller drivers in Compatibility Mode

If you were unable to install the Universal Serial Bus controller drivers you’ve downloaded, you can try installing them again but this time using Compatibility mode. Follow the steps below to do so:
  • You need to download the driver and place it on your desktop.
  • After that, right-click on it and select Properties.
  • Next, switch to the Compatibility tab where you should see two options:
    • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
    • Manually choose the version of Windows it was correctly working.
  • Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.
Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 5 – Run the Hardware and Devices Troubleshooters

  • The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
  • After opening Settings, look for the Update and Security option and select it.
  • From there, go to the Troubleshoot option located on the left-hand side of the list.
  • Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
  • After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Firefox shows wrong or no bookmark favicon
If you have just updated your Mozilla Firefox browser as of late and you noticed that it’s showing wrong or no bookmark favicon at all, then read on as this post will provide you with potential solutions that can help you resolve the problem. The basic thing you can do to fix it is to either refresh or reset the cache for favicon and then force restart the favicon service. However, if you’ve already tried this and it didn’t work, then there are still other options you can try. You can try to rebuild the configuration file for the favicon or restart the favicon service. You could also try disabling all the add-ons on your browser or scan your computer for adware. For more details, refer to each one of the options laid out below.

Option 1 – Try to rebuild the favicon configuration file

Mozilla Firefox actually creates a file each time you bookmark a webpage and this is called “favicons.SQLite”. This file is located on your computer and for you to fix the issue in Firefox, you need to rebuild this file and in order to do that, follow these steps:
  • First, you need to unhide the hidden files in your computer by enabling the “Show hidden files” option so that you’ll be able to see the hidden files in your computer.
  • After that, navigate to this path: C:Usersyour_usernameAppDataLocalMozillaFirefoxProfilesyour_profile_name
  • From there, you need to find the “favicons.SQLite” file and once you found it, delete it.
  • Next, you have to open the Firefox browser and create the same favicon configuration file which should be automatically created.
  • Now check if you can now see bookmark favicons on your Firefox browser or not.

Option 2 – Try to restart the favicon service

If the first option didn’t work, you can try to restart the favicon service instead. Restarting the favicon service can help if you do not see the correct bookmark favicon on your Firefox browser. To restart this service, follow the steps below.
  • You need to first open the Firefox browser and in the address bar, type “about:config” and tap Enter.
  • After that, you will see a page that displays a warning message. On that page, you need to click the “I accept the risk!” button to proceed.
  • Next, using the search box on the page, look for the “devtools.chrome.enabled” option. The value for this option should be set to “False” by default.
  • Double click on this option to set its value to “True”.
  • Once done, go to Menu > Web Developer > Browser Console or you could also tap the Ctrl + Shift + J keys, alternatively.
  • Afterwards, paste this command in the pop-up window that appears and then tap the Enter button: var fS = Components.classes["@mozilla.org/browser/favicon-service;1"] .getService(Components.interfaces.nsIFaviconService); fS.expireAllFavicons();
  • Once you’re done, restart your Firefox browser to check if it fixes the problem or not.

Option 3 – Try to disable all the add-ons in Firefox

The next option you can try to fix the problem is to disable all the installed add-ons in Firefox. More often than not, add-ons can cause issues in the browser so it is possible that one of the add-ons in Firefox is causing it to show incorrect or no bookmark favicon. To resolve this problem, you have to disable all the add-ons by opening Firefox and then going to Menu > Add-ons or you could also tap the Ctrl + Shift + A keys. After that, go to the Extensions section and click on the respective Disable buttons for each one of the add-ons. Once done, restart your computer and check if you can now see the bookmark favicons or not.

Option 4 – Try scanning your computer using Windows Defender

It is possible that the bookmark favicon problem is caused by some adware in the Firefox browser so you have to scan your computer to check by using security programs like Windows Defender.
  • Tap the Win + I keys to open Update & Security.
  • Then click on the Windows Security option and open Windows Defender Security Center.
  • Next, click on Virus & threat protection > Run a new advanced scan.
  • Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

Guide How to Remove PCOptimizerPro

PC Optimizer Pro is a PC optimizer utility developed by Xportsoft Technologies. It is classified as a potentially unwanted program, due to its aggressive scan and registration reminders, and that it is often distributed bundled with other programs in a manner that leads many users to not know how it got on their computer. While not inherently malicious, PC Optimizer Pro adds numerous registry keys, startup entries and while running consumes a relatively high amount of system resources, especially during its scans. The software installs from a .exe file that is around 5.20 MB or 5.453.240 Bytes (depending on the version). As of the publication of these videos, the current version of PC Optimizer Pro was detected as malicious or potentially unwanted by at least 21 AntiViruses.

About Potentially Unwanted Applications

If you have ever installed freeware or shareware, chances are high that your computer can get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has other hidden goals. These kinds of programs are almost always bundled up with free software which you download from the net or are also bundled within the custom installers on many download sites. PUPs did not really constitute pure “malware” in the strict sense of the term. Just like malicious software, PUPs cause problems when downloaded and installed on your PC, but what makes a PUP different is that you give consent to download it – although the truth is vastly different – the software installation package actually tricks you into accepting the installation. Irrespective of whether it is regarded as malware or not, PUPs are nearly always harmful to the user as they might bring on adware, spyware, keystroke logging, and also other bad crapware features on your computer.

What do PUPs do on your computer, exactly?

Potentially Unwanted Programs come in many forms and varieties, but in most instances, these are adware programs that show annoying pop-up adverts and advertisements on websites you check out. The PUPs also get installed into your computer in the form of web browser add-ons and toolbars. Not only they needlessly take up space on your computer screen, but toolbars may also manipulate search engine results, watch your web browsing activities, decrease your web browser’s efficiency, and decelerate your internet connection to a crawl. Potentially Unwanted Programs at times act quite similarly to viruses or spyware. Some PUPs include keyloggers, dialers, along with other software to gather your private details that may result in identity theft. These are programs that don’t do anything good for you; in addition to taking over space on your hard drive, they also slow down your computer, often modify settings without your approval, the list of bothersome features goes on.

Ways to avoid PUPs

• Always study the EULA and privacy statement. Don’t agree until you know precisely what you are acknowledging. • Choose the “custom” install whenever installing a software program. In particular, look closely at those small boxes that have been checked as default, where you may ‘agree’ to receive promotions or install software bundlers. • Use good antivirus software, like Safebytes Anti-Malware that offers real-time protection against PUPs. • Avoid adding a freeware program you do not use. Turn off or remove toolbars and web browser extensions you don’t really need. • Always download software from reliable sources like official sites as opposed to untrustworthy sharing space. Avoid file-hosting sites where/when possible.

What you can do if Malware Prevents You From Downloading Or Installing Antivirus?

Practically all malware is bad, but certain types of malware do much more damage to your computer than others. Certain malware goes to great lengths to stop you from downloading or installing anything on your personal computer, particularly antivirus applications. If you are reading this right now, you have probably recognized that a malware infection is the real cause of your blocked web connectivity. So what to do if you need to install an antivirus program like Safebytes? There are a few steps you can take to circumvent this problem.

Install in Safe Mode

The Windows OS has a special mode known as “Safe Mode” in which just the bare minimum required programs and services are loaded. In the event the malware is blocking the internet connection and affecting the computer, running it in Safe Mode will let you download antivirus and run a diagnostic scan while limiting possible damage. To start the computer into Safe Mode, press the “F8” key on your keyboard right before the Windows boot screen comes up; Or right after normal Windows boot up, run MSConfig, look over “Safe Boot” under Boot tab, and click Apply. After you reboot into Safe Mode with Networking, you can download, install, and update anti-malware software from there. Right after installation, run the malware scanner to remove standard infections.

Switch to an alternate browser

Some malware may target vulnerabilities of a specific browser that block the downloading process. If you seem to have malware attached to Internet Explorer, then switch over to an alternate web browser with built-in safety features, such as Firefox or Chrome, to download your favorite antivirus program – Safebytes.

Install and run anti-virus from the USB drive

Another solution is to create a portable anti-malware program on your USB stick. Adopt these measures to employ a thumb drive to clean your infected computer system. 1) Download Safebytes Anti-Malware or MS Windows Defender Offline onto a clean PC. 2) Plug the Thumb drive into the clean computer. 3) Run the setup program by double-clicking the executable file of the downloaded software, with a .exe file format. 4) Choose the flash drive as the location for saving the file. Do as instructed on the screen to complete the installation process. 5) Now, plug the pen drive into the corrupted computer. 6) Double-click the anti-malware software EXE file on the USB flash drive. 7) Press the “Scan” button to run a full system scan and remove viruses automatically.

What to do if CPU is not running at full speed
The speed at which the CPU runs varies depending on any Windows laptop or desktop. And in case you don’t know, the CPU does not run at full speed all the time as it depends on how the operating system distributes the load so it works accordingly. However, there are instances when it runs at full speed especially if your Windows 10 computer is on a heavy workload. But if you find that even when your computer is already on a heavy workload and the CPU is still not running at full speed, then you need to look into this situation. To verify that your CPU’s speed, you can use any CPU stress test tool. This kind of issue is common on laptops compared to desktop computers since laptop runs on battery. The Intel Processor on laptops uses the Speed Stepping Technology which means that when you are doing some small tasks on your laptop, the processor’s speed is reduced. On the other hand, if this happens when you are using a heavy application, it can be due to a low charge on the laptop’s battery. Thus, Windows will try its best to keep the computer running for as long as possible by reducing the CPU speed or processor. But there are times when you are ready to sacrifice battery to make sure that the work gets done on time. To achieve that, here are some options you can check out.

Option 1 – Try setting the processor state to the maximum in Power Options

  • Type “control” in the search box to view the classic Control Panel as well as the popular options.
  • Next, click on Power Options > Change plan settings > Change advanced power settings.
  • Then navigate to Processor power management > Maximum processor state.
  • Now select 100% when it is on Battery and Plugged in.
  • After that, expand the System cooling policy option and make sure to set it as Active to make sure that the battery won’t overheat.
  • Finally, apply the changes made to all the profiles of the power management and restart your computer. This will ensure that your CPU will run at maximum power at all times.

Option 2 – Try to update or disable the Intel Power Management driver

The next option you can try is to update or disable the Intel Power Management driver. The Intel-powered computers have dedicated software that controls CPU speed and Fan speed when it needs to save battery. You can try disabling it temporarily and check if there are any changes with the CPU fan speed.
  • First, restart your computer by holding the Shift key to boot your computer into Troubleshooting or Advanced mode.
  • Next, go to Troubleshoot > Advanced Options > Command Prompt.
  • Then change the directory to C:/Windows/System32/driver and then rename the file named “Intelppm” by entering the “ren intelppm.sys intelppm.sys.bak”.
  • Now restart your computer.
Note: If you were not able to find the drivers in C:/Windows/System32/driver, check if they are available under C:/Drivers/IntelPPM. After that, the CPU speed should change now with the Intel driver missing from the system. And in case you want to enable it, simply follow the same steps given above and rename the file again.

Option 3 – Try disabling the IPPM using the Command Line or Registry Editor

  • Command Prompt:
    • Tap the Win + R keys to open the Run dialog box and type “cmd” and tap Enter to open Command Prompt.
    • Next, type this command and hit Enter: sc config intelppm start= disabled
    • The “sc config” command you entered modifies the value of a service’s entries in the registry as well as in the Service Control Manager database.
  • Registry Editor:
    • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
    • Next, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesintelppm.
    • From there, double click on the intelppm and change the Start key value to
    • Now close the Registry Editor and reboot your computer.
Note: The steps given will make sure that the CPU will run at maximum power at all times.
