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.

Enable or Disable Automatic Encryption
You might be familiar with the Encryption File System or EFS algorithm if you rather keep your files and folders encrypted. Encryption File System is a built-in feature in Windows 10 which allows users to secure their important files. Although there is an alternative way for you to secure your data on your Windows 10 computer, you can’t ignore the fact that the main advantage of an Encryption File System over BitLocker is that the former can help you encrypt a particular folder rather than encrypting the whole hard drive partition. If you move a file inside a folder encrypted with the Encrypting File System it will automatically get encrypted. There are some users who like this feature but unsurprisingly, there are some that don’t. So if whether you want your files encrypted when you place them in an encrypted folder or if you want to keep it as it is, read on as to how you can do it either way. You can enable or disable automatic encryption of files moved to encrypted folders in Windows 10 using the Registry Editor or the Group Policy Editor. Before you proceed, make sure to create a System Restore Point first because the modifications you’re about to make in your computer might affect its overall functioning so if anything goes wrong, you can always undo the changes. Once you have that covered, refer to the options given below to enable or disable automatic encryption in Windows 10.

Option 1 – Enable or disable automatic encryption using Registry Editor

  • Press the Win key + R key at the same time to open the Run dialog box.
  • Then type “Regedit” in the field and press Enter to open the Registry Editor and if a User Account Control or UAC prompt appears, just click Yes to proceed.
  • After opening the Registry Editor, navigate to this key location: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesExplorer
  • Next, right-click on Explorer and select New > DWORD (32-bit) Value and then name the newly create DWORD to “NoEncryptOnMove” and press Enter to save it.
  • After that, double click on the NoEncryptOnMove DWORD and set its value to the following preferences:
    • 1 – Disable Auto Encryption of files moved to encrypted folders.
    • 0 – Enable Auto Encryption of files moved to encrypted folders.
  • Now close the Registry Editor and restart your computer to successfully apply the changes made.

Option 2 – Enable or disable automatic encryption using the Group Policy Editor

  • Press the Win + R keys to open the Run box and type “gpedit.msc” in the field and press Enter to open the Group Policy Editor.
  • After that, navigate to this path: Computer ConfigurationAdministrative TemplatesSystem
  • Next, look for the “Do not automatically encrypt files moved to encrypted folders” option and double click on it to set the policy. From there, you will see the following description:
“This policy setting prevents File Explorer from encrypting files that are moved to an encrypted folder. If you enable this policy setting, File Explorer will not automatically encrypt files that are moved to an encrypted folder. If you disable or do not configure this policy setting, File Explorer automatically encrypts files that are moved to an encrypted folder. This setting applies only to files moved within a volume. When files are moved to other volumes, or if you create a new file in an encrypted folder, File Explorer encrypts those files automatically.”
  • Now select one of the radio buttons below depending on your preference:
    • Not Configured or Disabled: Enable Auto Encrypt of files moved to EFS Encrypted folders.
    • Enabled: Disable Auto Encrypt of files moved to EFS Encrypted folders.
  • Then click on the Apply and OK buttons to save the changes made.
  • Exit the Group Policy Editor and restart your computer.

Is it wise to keep old electronics

Hello all the wonderful people and welcome to our new article where we take a little different turn than usual and discuss why keeping old electronics around the house is not such a good idea. We all have some drawer or in some bag around the house and in the end of the day if that electronic has battery inside it is probably not the smart thing to keep it.

So naturally, the question comes why it is a bad idea to have old electronics with batteries in them? Well unlike a battery failure with, say, some AA batteries jammed in the back of an old toy, the risk with a lithium-ion battery failing isn’t just some leaking and corrosion in the battery compartment, it’s a potential fire as the battery swells up and the gases (combined with the stored energy) turn the battery into a potential fire hazard.

Good thing is that the battery will not explode just like that, it will swallow over time and get bigger and bigger until the breaking point is reached and all the fire breaks lose. So if by any chance you have some old gadgets lying around you can check up on them and see if has swelling process started, if yes, dispose properly of that piece of the old device immediately.

How to keep old electronics

If you’re not ready to get rid of the gadget then it’s best to charge it properly for storage. Proper charging keeps the battery cells and circuits in optimum health.

While recommendations vary by manufacturer and application, the general consensus is that lithium-ion batteries should be charged to approximately 40%. (Some manufacturers recommend charging 50% or 60% instead.)

Really, the important part here isn’t the exact percentage. What’s important is ensuring that the battery is charged to roughly half capacity and not stored with a completely discharged or completely full battery.

Discharge rates on lithium-ion batteries in completely powered-off devices are very slow, but you should still plan to top off the charge every 12-18 months or so to keep it around 50%.

If you wanted to go above and beyond, a metal storage container with a snug lid on a basement shelf with a desiccant pack inside to control the moisture would offer optimum conditions.

Problem prevented document from being scanned
If an error suddenly pops up that states, “A problem prevented the document from being scanned” when you’re scanning a document in your computer, then you’ve come to the right place as this post will guide you on how exactly you can fix the problem. A lot of users have reported that they receive a two-layer error message when they try to scan their documents – the first screen throws an error message that says, “Error applying Settings to Driver” while the next error message states, “A problem prevented the document from being scanned”. As a result, the scanning won’t be completed which defeats the whole process of buying a printer with a scanner. As you can see the two error messages point to two different situations, while the other one is pointing at the driver, the second one points to the scanning problem. To resolve these issues, there are several suggestions you need to check such as follows:

Option 1 – Run the Printer Troubleshooter

One of the first basic troubleshooting you can perform to resolve the printer issue is running the Printer Troubleshooter. This built-in troubleshooter can detect and automatically fix the problem for you. To use it, follow these steps:
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “msdt.exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
  • Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Option 2 – Try updating the Printer drivers

You might also want to try updating your printer drivers. All you have to do is locate the USB Composite Device. For complete details, follow the steps below.
  • 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 USB Composite Device option and right-click on it, and select the Update Driver from the options.
  • Restart your PC and then click the “Search automatically for updated driver software” option.
Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

Option 3 – Try to reset the settings of the Printer or reinstall it

If none of the two options given above worked, you can try to either reset the printer settings or reinstall the printer so that it can go back to its default state. However, if it doesn’t work, you can try to uninstall the printer as well as its related drivers. To do so, follow these steps:
  • First, go to Settings > Devices > Printer and Scanners.
  • After that, select the printer and select the Remove Device option.
  • Once done, restart your computer and check again and see if the error is now fixed.

Option 4 – Try to modify the Registry settings for the Still Image devices

In case you don’t know, Windows has Registry settings for the Still Image devices like Scanners and Printers. And these devices have vendor-specific settings that if ended up getting corrupted or misconfigured then you will most likely encounter errors like “A problem prevented the document from being scanned”. Thus, to fix this error, you can try modifying the Still Image devices registry settings, and to do that, you need to follow the instructions below but before that, make sure that you create a System Restore Point first.
  • Once you’ve created a System Restore point, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and then hit Enter to open the Registry Editor.
  • Next, navigate to this registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStillImage
  • From there, right-click on the “StillImage” registry key and delete it.
  • After that, exit the Registry Editor and restart your computer.
  • Once your computer has restarted, Windows will recreate the settings of the Still Image devices back to their default settings.

How to Fix ACPI.sys Blue Screen Error
If, while using your computer, you encounter the ACPI.sys Blue Screen error, read on as this post will guide you in fixing the problem. The ACPI.sys file is a Windows operating system file that is related to the MSDN 2939. ACPI.sys, the Windows ACPI driver, is an inbox component of the Windows operating system. It is the one that supports the power management as well as the Plug and Play or PnP device enumeration. And so if this file ends up getting corrupted, it is known to cause a Blue Screen error. Another possible cause for the ACPI.sys Blue Screen error includes RAM issues, incompatible firmware, hard disk issues, corrupted drivers or malware infection, and so on. Here are some Blue Screen errors that can be triggered by the ACPI.sys file:
  • KMODE EXCEPTION NOT HANDLED
  • PAGE FAULT IN A NONPAGED AREA
  • SYSTEM THREAD EXCEPTION NOT HANDLED
  • IRQL NOT LESS OR EQUAL
  • KERNEL DATA INPAGE
  • SYSTEM SERVICE EXCEPTION
To fix the Blue Screen error associated with the ACPI.sys file, refer to the instructions provided below.

Option 1 – Try to recreate the ACPI.sys file

If the first option didn’t work, the next thing you can do is to recreate the ACPI.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.
  • Boot your Windows 10 PC in Safe Mode.
  • Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
  • From there, look for the file named ACPI.sys and rename it to ACPI.old.
Note: As you can see, the file’s extension has changed from .sys to .old.
  • Now restart your computer and check if the ACPI.sys Blue Screen error is now fixed.

Option 2 – Try to update or rollback the ACPI Driver

The first thing you can try to fix the Storport.sys Blue Screen error is to either update or roll back the 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.
  • Tap the Win + X keys to open the Win X menu and from there, select the Device Manager.
  • After opening the Device Manager, look for the ACPI.sys driver and right-click on it, and then select Properties.
  • Next, go to the Driver section. Note that the rollback option would only be available if you’ve recently updated the ACPI.sys driver. So if you can’t see it then click on the Update Driver button.
  • After that, Windows will automatically check for the problems that could be related to the Blue Screen error.
  • Finally, restart your computer. It will just reinstall the device drivers automatically.
Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver. On the other hand, if updating the ACPI driver, didn’t work, you can also try to copy the ACPI.sys system driver file from the System32 folder of another computer that’s functioning properly and runs the same Windows OS version. Afterward, place it on your problematic computer and check if it fixes the BSOD error or not.

Option 3 – Run System File Checker or SFC scan

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. 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.
 Reboot your PC.

Option 4 – Run the Blue Screen Troubleshooter

Troubleshooting Blue Screen of Death errors wouldn’t be complete without the Blue Screen troubleshooter. As you know, it is a built-in tool in Windows 10 that helps users in fixing BSOD errors like ACPI.sys. 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 – Run 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.

What is and how to Remove Shortcut Virus
Shortcut virus is an easily spreadable and annoying combination of Worm and Trojan that hides all of your files and folders and then replaces them with shortcuts that look identical to replaced files and folders. Shortcut virusOnce disguised it will wait patiently for a user's click and once that happens it will replicate itself and further infect the system. This rapid spread can lead to stolen personal data, some system hick-ups, and other system-related issues. This malware mainly affects physical file transfer devices like for example and most USB drives, hard drives, and SD memory cards and it can easily transfer itself to the computer. The advantage of this shortcut virus comparing it to others is that it is mostly undetected by a vast variety of antivirus software. So running just anti-virus software maybe not be enough to remove it from your system. Luckily for all unfortunate users that have caught this annoyance, it can be easily removed fully manually in a short time.

How to Remove Virus from USB and other removable media

Firstly plugin USB, SD, or removable drive. The infection will transfer to your computer when the infected drive is plugged in so before we go to clean the computer itself, clean each removable drive that you have. Also know that infection will spread from computers into removable devices as well if it is not cleaned. Open the File Explorer and remember under which letter is removable drive registered. Open Command prompt but with administrator privileges and go to infected rive by typing its letter followed with “:” (for example D:) and press ENTER Once you have successfully gone to infected drive type in command prompt: Attrib -s -r -h /s /d *.* This will unlock all original files back into removable storage, next copy all files to your computer, and format the removable drive. Once the format is complete, unplug the removable device. Continue to clean all devices with the same method.

How to Permanently Remove a Shortcut Virus from Your PC

Now once we have cleaned all removable devices it is time to fully clean the PC Firstly open the task manager ( CTRL + SHIFT + ESC ), in the process tab find wscript.exe or wscript.vbs, right-click on it (or both if present), and select End Task. Now close the task manager and press Start. Inside start typing in registry editor to search for it and once found open it. Find the following key inside the registry editor: HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Run In the right panel, look for any strange-looking key names, such as odwcamszas, WXCKYz, OUzzckky, etc. For each one, run a Google search to see if it's related to shortcut viruses. If any returns a positive match, right-click on them and select Delete. !!! Accidentally deleting an important key can cause Windows to become unstable, so double-check everything !!!. Close the Registry Editor Now press ⊞ WINDOWS + R to open the run dialog and type in it Msconfig followed by ENTER. Once the System Configuration window opens go to the Startup tab. In the Startup tab, look for any strange-looking .EXE or .VBS programs, select each one and click Disable. Close the Window. Once again open the run dialog and type inside %TEMP% and press ENTER in order to open the Windows temp folder. Inside this folder delete everything. Next in the File explorer go to C:\Users\[username]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup Look for any strange-looking .EXE or .VBS files and delete them.

Fix System Interrupts high CPU usage
System Interrupts are operating system processes that function as an alert system for the CPU. So whenever a scenario needs the attention of the CPU, it alerts the CPU about it. In turn, the CPU suspends what it is doing, saves it, and then takes care of that important job and once that job is completed, it resumes back to what it was doing. This indicates that although System Interrupts appears as a process, it’s actually not. As a matter of fact, it is like a manager that reports to the CPU about all interrupts that happen on a hardware level, e.g. hardware interrupts. And if there are lots of interrupts, this means that there might be various errors occurring on a hardware level. As a result, it may take a lot of system resources. And if you consider disabling System Interrupts, stop right there as your computer will almost become useless without it. So if you see System Interrupts consuming high CPU usage in your Windows 10 computer, you can fix it without having to disable it and cause more problems. If System Interrupts takes up more than 5 to 10% of CPU, then you definitely have a problem. This could be happening due to some hardware or driver issue. The first thing you can do is to try rebooting your computer once and see if the issue comes back or not. High CPU usage of System Interrupts is a huge backlog for the CPU and it stays in the loop. If a simple system restart didn’t fix this issue, here are some suggestions you can try.

Option 1 – Try to update the hardware drivers

As stated, the problem might have something to do with hardware drivers so you can try to update these drivers and see if it works.
  • Reboot your computer into Safe Mode with networking support.
  • Tap the Win + R keys on your keyboard to open the Run dialog box.
  • After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
  • After opening the Device Manager, update all the outdated Hardware drivers on your computer.
  • Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
  • Now restart your PC and check if the BSOD error is fixed or not.
Note: On the other hand, if a recent update has caused the System Interrupts high CPU usage, then you might want to roll back your hardware drivers to their previous versions. You can check with the Windows Update History to check out any recent updates as well as the previous ones.

Option 2 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:
  • 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 configure Windows to use the usual startup, just simply undo the changes.)

Option 3 – Try to enable or disable Hardware

If you do not want to remove hardware, you can just disable them using the Device Manager. Note that this can also be applied to the internal hardware.
  • Tap the Win + X + M keys to open the Device Manager.
  • Next, navigate to the device you want to disable.
  • Then right-click on it and choose to disable the device.
Note: Make sure that you disable one device at a time and then give it a couple of minutes and check if there are any changes in the CPU usage to pinpoint the hardware. And if there is no change, you need to enable the device you’ve just disabled and then proceed to disable the next hardware device. If there are changes, then it’s probably the culprit. Just keep in mind that you must no disable any device that is needed to keep your system up and running.

Option 4 – Try to update the BIOS/UEFI

Updating the BIOS/UEFI can help you fix the high CPU usage of System Interrupts 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.
  • Restart your computer to apply the changes made.

Option 5 – Run the Hardware and Devices Troubleshooter or the Performance Troubleshooter

Hardware and Devices Troubleshooter:
  • 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.
Performance Troubleshooter:
  • Tap the Win + R keys to open the Run dialog box.
  • Type “exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
  • Then click on Next to get started. Wait until the process is completed.

Fix Windows defender 0x800700AA Error
Windows defender error 0x800700AA, service can not be started comes when the user is trying to run Windows defender scan on their system. This kind of behavior happens for two reasons mostly, third-party application conflict or corrupted system files. In this article, we will tackle both scenarios and provide you with solutions in both cases.

Third-party application conflict

In this rare scenario when Windows defender can not start scan due to conflict with installed service or application in the system solution is quite simple. Restart your PC into safe mode and run the scan from there. In a safe mode environment, minimum drivers and services are only loaded eliminating any conflicts that might occur when everything is booted. If Windows defender can not run the scan in safe mode and you get the same 0x800700AA error then you can eliminate application conflict as a reason and move to the next solution which will tackle corrupted system files. If you, however, managed to run a scan then you have a rare third-party application conflict, you can boot normally into windows and try to eliminate one by one to see which one is causing the issue. The safest bet would be to start with security software because most of the time that is what causes conflicts in running services and applications.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:
  1. Run SFC scan

    SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer
  2. Run DISM scan

    DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC
