We’ve already covered disabling Security Questions If you want to disable Security Questions on your Windows 10 computer then you’ve come to the right place as this post will guide you in doing exactly that. In this post, you will be disabling Security Questions using a PowerShell script. This PowerShell script is called “Update-AllUsersQA”. It is designed to remove or disable the security questions and answers for local users on a Windows 10 computer. It lets administrators take control of the security questions in the environment and at the same time minimizes the risk that comes with them. If a user has a Microsoft account that’s configured to sign in to Windows 10 then he will not probably notice the Password Recovery questions. On the other hand, if he has a chosen local account for installing Windows, he will e prompted to create three security questions that can be used to reset the password and log into the Windows 10 account in case there is any misfortune. However, if you do not have much use for these Security Questions, then you can definitely have them disabled using a simple PowerShell script which you can download from GitHub. For more details on how to disable security questions in a Windows 10 machine, refer to the steps provided below. Step 1: You need to first download the .ps1 file from the GitHub repository. Step 2: Once you’ve downloaded the file, open the PowerShell window with admin privileges. Step 3: After that, navigate to the folder where you had saved the .ps1 file. Then copy the address of the folder location. Step 4: Next, change the directory by using the following command:

cd "folder location address"

Step 5: After that, enter the following script to disable the security questions:

Update-AllUsersQA

Once you’ve completed the steps above, the Security Questions should be disabled and you will be notified with a message stating that the feature has been disabled. On the other hand, if you have a change of heart and you want to enable the Security Questions back, here are some steps you need to take: Step 1: First, open the PowerShell window as admin. Step 2: Next, run the same script with one more parameter such as:

Update-AllUsersQA -answer SecretAnswer

Step 3: And that’s about it. Do not forget to replace the Secret Answer with your preferred one and once you’re done, it will be set as the answer for all the Security Questions. Step 4: Now all that’s left to do is go to the Settings app to change the answer to the questions and you should be good to go.

There are instances when the Windows 10 installation needs interaction before it reaches the file process. And so if you suddenly encounter the Windows Update Installation Failure 0x80240020 error under the Windows Update History, then you need to get it fixed. When you encounter this kind of Windows Update Error, you will see an error message that says, “The operation did not complete because there is no logged-on interactive user”. This error also indicates the “WU_E_NO_INTERACTIVE_USER” code. To resolve this issue, in this post we’ll walk you through a couple of steps but before you get started, know that you don’t have to run any troubleshooter or delete any file just to fix this error since all you have to do is enable one option that can automatically login with your account and complete the installation for you. With that said, just make sure to only try running Windows Update once you’re told to do so. There are two ways you can enable the option that could resolve the Windows Update Installation Failure 0x80240020 error. One is via Settings while the second one is via Registry Editor.

Option 1 – via Settings

Step 1: Go to Settings > Accounts > Sign-in Options. Step 2: From there, toggle on the “Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart” option. Step 3: After that, it will make sure that the interaction part is removed from the Windows Update process. Note: If your device is joined in a domain or if some work or email policies are applied to your device by your company or organization, then you wouldn’t be able to see this option in Settings and that’s where the Registry Editor comes in. Just make sure that you’re logged in as an administrator and that you create a System Restore Point first since registry hacks are sensitive and could highly impact how your computer behaves or functions. Once you have that covered, follow the steps below.

Option 2 – via Registry Editor

Step 1: In the Start search, type “Regedit” and hit Enter to open the Registry Editor. Step 2: Navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgrade

Note: If the above-given registry key does not exist, you can simply create it. All you have to do is right-click on the WindowsUpdate key and then select the New Key option and type “OSUpgrade” as its name. Afterward, create a new DWORD (32-bit) Value and name it “AllowOSUpgrade” and set its value to 0x00000001. Step 3: Restart your computer and check if the error is now fixed. And then try to update your Windows 10 computer again and while you’re at it, make sure that you’re around your computer to interact with the prompts needed to complete the installation process.

We tend to move and copy tons of files on our PCs and mostly, the process of copying or moving files, especially if the file has the size of 1GB or up, tends to take quite long. This may be caused by some issues which is why you face slow copy or move speed. So if you are experiencing this issue on your Windows 10 computer, then read on as this post will give you a couple of solutions you can try to increase the speed in copying or moving files. Follow the given instructions below.

Option 1 – 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. It may sound nothing but changing the USB port can actually improve the copying or moving speeds drastically so this should be the first thing you can try to speed up the process of copying or moving files.

Option 2 – Update the USB Controller Drivers

• 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.
• Restart your PC and then click the “Search automatically for updated driver software” option.

You also have the option to update the motherboard and the USB driver from the manufacturer’s official website.

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 – Try to disable Windows Auto Tuning

Disabling Windows Auto-Tuning can also help in increasing the copying or moving of files in your computer. It is said that this feature improves the performance of programs that receive TCP data over a network by adjusting the receive buffer size dynamically throughput and latency of the link. Thus, if you are trying to copy some data over the network, then the Auto Tuning feature is playing a role here. And in some cases, disabling this feature completely resulted in a lot faster copy speeds over the network.

Option 5 – Try changing the USB Removal Policy

• First, plug your USB drive or external device into your PC and then open This PC.
• Next, right-click on your device and select Properties.
• After that, go to the hardware tab and select the storage media that you want to enhance and then click on the Properties button.
• From there, you can select the Better performance option if you wish for your device to have a better performance. Once you select this option, it will enable write caching in your Windows 10 computer but you need to use the “Safely Remove Hardware” option from the notification area to safely disconnect the device otherwise it may result in data corruption.

Option 6 – Format your drive

• To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
• Next, right-click on the drive and select Format.
• After that, uncheck the “Quick Format” option and then format your drive properly.
• Now once the formatting process is finished, unplug the drive and plug it back in afterward.
• Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
• After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
• From there, right-click on the drive volume and select initialize disk.
• Next, select the correct partition type and proceed.

The quickest and easiest way to log into your computer is when you use the PIN feature in Windows 10. Even though it is a bit slower compared to biometric logins such as Fingerprint and Iris scanning that comes under Windows Hello, the PIN feature is definitely less complicated. However, just like any other module of the software, it is also prone to some errors. In this post, you will be guided in fixing several PIN errors such as 0xd00000e5, 0x8007139f, and 0x8009003. These errors could be caused at different points in time like when you change or create a PIN or when you log into your computer. To fix the 0xd00000e5, 0x8007139f and 0x8009003 PIN errors, there are various solutions you can try. You may empty the contents of the NGC folder or remove and change the PIN or the password. You could also use the Group Policy Editor or reset the ACLs in the NGC folder as well as run built-in tools like System File Checker and the DISM tool.

Option 1 – Take ownership of the NGC folder and delete its contents

• Boot your computer first into Safe Mode.
• Next, you need to take ownership of the Ngc folder first and you can do that using Command Prompt.
• Type “command prompt” in the Windows Search bar and then right-click on the relevant search result and select “Run as administrator”.
• After that, if a User Account Control or UAC prompt appears, just click on Yes to proceed.

• Once it’s done, restart your computer.

Error Code 36 – What is it?

This is a common Device Manager Error Code that users encounter. It is commonly found on all Windows 2000 and later versions of Windows operating systems. Error Code 36 is usually prompted by the following message:

"This device is requesting a PCI interrupt but is configured for an ISA interrupt (or vice versa). Please use the computer's system setup program to reconfigure the interrupt for this device. (Code 36)"

Solution

Error Causes

Error Code 36 occurs when there is a failure in IRQ translation due to your Windows operating system getting corrupted. This is caused due to a number of triggers, such as:

• An excess of startup entries
• Errors in registries
• RAM or hardware failure
• Excessive unnecessary installed programs
• Malware or spyware

When programs are removed excessively, some programs are not removed completely and create problems in your computer’s registry.

Also, due to the presence of malware and spyware and other causes mentioned above, your computer registry builds up errors with the time that leads to slowing your PC, time lags, and even result in crashes and freezes.

Error Code 36 can cause internal and external components to malfunction or experience time lags such as DVD drive or printer and hence can severely affect your entire PC.

Further Information and Manual Repair

Error Code 36 is a severe PC error and any attempt at fixing the error must be approached with extreme caution for your PC to start functioning properly again. Here are two methods to fixing your PC.

Method 1 – Change IRQ reservation settings

Changing the IRQ reservation settings is the best way you can rely on to fix the error code. You can do this by changing the BIOS settings of your PC.

The BIOS stands for ‘Basic Input/Output System’ and is the program of your PC’s microprocessor that allows your PC to boot after you switch it on.

Caution needs to be exercised before changing the BIOS settings of your PC. This is because every PC’s BIOS version differs from another and any wrong attempt to change the settings may make matters worse.

It is therefore recommended to refer to hardware documentation that you received with your PC or motherboard and check for the model number and details of your PC’s motherboard.

Only after you have checked and confirmed all the details, should you use the specific BIOS settings required to configure your IRQ reservations?

Method 2 – Install DriverFIX

Error Code 36 isn’t an easy error to remove.

While changing the BIOS settings can work to restore your PC, it may create a whole lot of inconvenience for finding the time and effort to check the hardware documentation details and attempting to change the specific settings and especially, if your PC does not support the options to change IRQ reservations.

Given the high risks of fixing such an error, you can also install software that enables you to fix your slow PC at the click of a few buttons.

Programs such as DriverFIX can enable you to download and replace your outdated drivers with new updated ones without you having to look for them. It will detect which drivers to download based on your PC’s motherboard version from the program’s database and can get rid of error code 36.

Click here to download DriverFIX and remove error code 36 and any other type of Device Manager error from your PC.
