As you know, each one of the applications that you use in your Windows 10 computer has its own set of permissions by default. These applications either allows or denies the interactions between a few other applications, depending on their own needs. This is why you might suddenly encounter a message that says,

“This app wants to access your pictures” or “This app wants to access your account info”

both of which are followed by two buttons that will ask you to Allow or Deny the action. You can always click on any of the given options. This will determine the permission of the application. Users in Windows 10 are given the option to either allow or deny applications in accessing their account information like name, picture and other account information. Thus, in this post, you will be guided on how you can change the Privacy settings of these apps to allow or deny them permission to access not just your account info but for all users, as well as specific apps in Windows 10. The user account information is part of the Privacy data in Windows 10 that you can control easily using the Settings app. In fact, you can revoke or grant access permission for your account information, all the users and specific applications to do that, follow each one of the instructions provided below carefully.

Allow or deny apps permission to account info for yourself:

Step_1: The first thing you have to do is open Settings. From there, select Privacy. Step_2: After that, scroll and look for Account info and select it. Step_3: Now turn off the toggle button for the “Allow apps to access your account info” option if you want to deny apps permission to your account info. But if you want to allow them access, simply turn the toggle button on. Keep in mind that when you allow access or permission, you can select which apps can access your picture, name, and other account info by simply using the settings on the page you’re currently in.

Now if you want to allow or deny apps to access your account info for all the users, here’s what you have to do:

Step_1: First, open Settings and click on the icon for Privacy. Step_2: Next, scroll down until you see the Account info located on the left side and then click on it. Step_3: After that, click on the Change button under the “Allow access to account info on this device” section. If you want to deny account info access for all other users, then turn the toggle button off. Doing so will automatically disable not just the account info access for all users but also for all the apps as well.

On the other hand, if you want to allow or deny account info access to specific apps, you can do so by following these steps:

Step_1: As you did earlier, go to Settings and click on the Privacy icon. Step_2: After that, scroll down and select Account info located on the left side. Step_3: Now turn on or off the toggle button under the “Choose which apps can access your account info” section if you want to deny or allow specific apps permission to access Account Info. If you’ve turned on the toggle button under the “Allow apps to access your account info”, all the apps get access permissions by default.

No Audio Device Error

What exactly is no audio device malfunction?

No audio device error is among the malfunctions that many Computer consumers run into. No sound or audio can be heard from the computer when the error occurs.

Solution

Error Causes

There are numerous elements that may be the basis of this malfunction. Corrupted or broken sound card drivers, incorrect Device Manager Options for example, or even incorrect BIOS configurations.

Further Information and Manual Repair

How could you recover the standard production of audio by your personal computer and solve this malfunction? Like a number of additional malfunctions, the method of the repair depends on its trigger. To properly solve this dilemma, you are required to run through an evaluation of the pc system so that you can pinpoint the cause. This is because there are numerous variables, which alone, or concurrently may trigger this dilemma. These measures will allow you to work out the no sound device error in your personal computer programs, identify the trigger and fix it. Follow the directions in step 1 if your computer has an onboard audio device installed in it and assess the BIOS settings. You can jump step 1 and move to step two if you utilize a separate sound card.

STEP #1 - Assess the BIOS options.

No sound device error can be caused by incorrect BIOS configurations in your Personal Computer. By fixing these settings if they are the cause of the malfunction, you can easily solve it. Make Sure you restart the pc and immediately access the BIOS options. By locating the Sound card, which is usually known as the AC97 Audio, you should subsequently open the Integrated Peripherals. As soon as you locate it, set it to Allow or Auto. Finally, you should access the On-Board Audio AC97 Control and set it to Allow or Auto as well. If it doesn't solve the situation, proceed to Step Two.

STEP #2 - Analyze the Device Manager

No sound device malfunction can be additionally caused by malfunctions with the Device Manager. To solve this issue, go to My Computer, right-click it, select properties, click on the Hardware tab, then click on Device Manager. At this windowpane, analyze the movie, audio, and game controllers. If you learn that there is a cross on any of the sub things, right-click it subsequently and set it to Enable. The sound card driver may have not been correctly installed or may be damaged if there is Exclamatory Mark or Question Mark on the device manager menu. This does not mean that the sound card driver is ok. It may have malfunctioned even though you do not locate anything unusual. This is because the Device Manager doesn't always recognize errors in audio hardware. After this, you can proceed to step 3.

STEP #3 - Upgrade or reinstall the Sound Card Driver.

About 80% of "no sound system discovered/installed" malfunctions come from broken and/ or out-of-date card drivers. The sound card will not be detected by the Windows Operating System, when the audio card driver is corrupted, damaged, or out-of-date and therefore no sound will be produced by your computer. If this is the cause of the no sound device malfunction, you should reinstall the Audio Card Driver on your computer. Still, you can utilize driver upgrade applications on the web that will help you upgrade out-of-date drivers.

Windows PowerShell is a powerful tool inside the Windows environment often overlooked by typical users which is a great mistake since it can offer a large array of functionality and usability and if used well can offer a unique working experience. Today we will be using PowerShell to turn the WEB camera off so it can not be accessed, completely disabling it for use. You might want to do this for security reasons or just want to learn few new things. Whatever your reason might be, I am welcoming you to this tutorial and please do keep reading.

Finding device ID

In order to disable the WEB camera first thing we need to do is to find a matching device ID. We will find this value inside the device manager, so press ⊞ WINDOWS + X to open the secret menu. In the menu choose device manager and click on it. When the device manager opens, expand the Imaging devices or Cameras section. Right-click Integrated Camera or the primary webcam, and click Properties. Go to the Details tab. Under the Property section, click to select Matching device ID from the drop-down. Right-click the value and select Copy The next step is to download and install Windows Driver Kit (WDK)

PowerShell script

Create and run a PowerShell script with the following parameters/values to disable the camera. Substitute the <FOLDER> placeholder with the actual name of the folder where your copy of Devcon is residing

$id = (Get-CimInstance Win32_PnPEntity |

where caption -match '<PRIMARY CAMERA>').pnpDeviceID

$ppid = "{0}{1}" -f '@',$id

Set-Location c:\<FOLDER>

Devcon status $ppid

Devcon disable $ppid

Devcon status $ppid

To enable the camera device, run the command below in PowerShell:

devcon enable $ppid

If you’ve been using your Windows 10 PC for a long time now, you might have come across a couple of issues – from minimal ones to critical ones like the Blue Screen of Death or BSOD stop errors. One of these BSOD errors you can encounter is the DRIVER_IRQL_NOT_LESS_OR_EQUAL Blue Screen error. This particular BSOD error is caused by iaStorA.sys, iaisp64 sys, Netwtw04.sys, nvlddmkm.sys, ndis.sys, wrUrlFlt.sys, and other driver files on Windows 10. This error indicates that a kernel-mode driver tried to access pageable memory at a process IRQL that was too high. When you encounter this error, just like a typical BSOD error, your computer will abruptly stop and you will see a blue screen with an error message saying:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (100% complete) If you’d like to know more, you can search online later for this error: DRIVER_IRQL_NOT_LESS_OR_EQUAL (wrUrlFlt.sys)”

The iaStorA.sys file is a software component that’s related to the Intel Rapid Storage Technology by Intel. It is a software solution supported by Intel Smart Response Technology which allows the PC to communicate with the hardware as well as externally connected devices. The Intel Rapid Storage Technology enables the Peripheral Component Interconnect Express or PCIe storage support, serial ATA RAID or Redundant Array of Independent Disks 0, 1, 5, and 10 support, and the PUIS or power-up in standby is also supported. To resolve this kind of BSOD error, you have to update, roll back or fresh-install the problematic driver. Refer to the options laid out below for detailed instructions.

Option 1 – Try removing the Intel Rapid Storage Technology or IRST drivers

The first thing you can try is to fix the Wi-Fi driver or the Ethernet driver on your computer to resolve the BSOD error. Take note that this option works not only on Windows 10 but also other Windows versions.

• 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, click on the “IDE ATA/ATAPI Controller” entry and expand it.
• Next, right-click on all the driver entries that are appropriately labeled, and then click on Uninstall device.
• Now restart your PC and check if the problem’s fixed or not. If not, proceed to the next given option below.

Option 2 – Try updating the Intel Rapid Storage Technology or IRST drivers

If you’ve already tried uninstalling the IRST driver but you’re still getting the DRIVER IRQL NOT LESS OR EQUAL Blue Screen error when you use your Windows 10 PC, then this means that the drivers might be corrupted or not compatible with the operating system version that you are using right now. So to fix the problem, you have to update your drivers. To do that, follow the steps below.

• The first thing you need to do is to go to your OEM’s website.
• Once you’re already on the OEM’s website, go to the Drivers section and get the latest version for your device and then try to overwrite it.

Alternatively, you can also update the drivers via the Device Manager:

• 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, click on the “IDE ATA/ATAPI Controller” entry and expand it.
• 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.

Option 3 – Try using the System File Checker via Command Prompt

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 to good system files that might be causing the DRIVER IRQL NOT LESS OR EQUAL Blue Screen error. 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.

If you are using Windows PowerShell and it suddenly throws an error message saying, “File cannot be loaded because running scripts is disabled on this system”, then read on as this post will guide you on how you can fix this issue your Windows 10 computer. This kind of error in PowerShell is most likely due to the fact that your user account does not have the required permissions to execute the script. Although this does not mean that you need to have administrator-level permissions as it could also indicate that you have to be unrestricted to run these types of PowerShell scripts or cmdlets. Thus, to fix the error and carry out the task, you have to set the execution policy to be unrestricted. And to do that, you need to use the steps provided below as a reference. Step 1: To get started, you have to check what policies are set for the individual user groups on your computer by tapping the Win + X key combination or by right-clicking on the Start button and clicking on Windows PowerShell (Admin). You can also search for PowerShell in the Start Search and then right-click on Windows PowerShell and select Run as administrator. Step 2: If a User Account Control or UAC prompt appears, just click Yes to proceed. Once you’ve pulled up Windows PowerShell, type the following command to get the List of Execution Policy for all the scopes on your computer.

Get-ExecutionPolicy –List

Step 3: After you execute the command, it will give you a list of the User Groups as well as their Execution Policy status, and under the Scope column, look for “LocalMachine”. Once you find its Execution Policy you will notice that it’s either set to Undefined or Restricted. Step 4: Now that you’ve determined the Execution Policy, you need to set it to Unrestricted if it is set to Restricted. To do that, you have to enter the following command in the very same PowerShell window.

Set-ExecutionPolicy Unrestricted

Step 5: After you execute the command, you will see a message that asks for various permissions for which you either have to tap Y to say Yes to each one of the messages individually or tap the A key to say Yes to all the messages to once. However, if the command throws another error, you can just force the Execution Policy to change by executing the following command.

Set-ExecutionPolicy Unrestricted -Force

Step 6: Once you’re done, it will finally set the Execution Policy for the Windows PowerShell scripts as well as cmdlets to be Unrestricted and fix the “File cannot be loaded because running scripts is disabled on this system” error.

High Dynamic Range or HDR is a technique that’s used to create lifelike videos which have improved and better dynamic range, especially when it comes to details. And as you know, Windows 10 supports the steaming of HDR videos as long as the display supports it and it comes with the option to enable the HDR Playback for Windows 10 Video Streaming apps. However, before you can get the best viewing experience, you need to calibrate the display further for HDR video on your Windows 10 PC. Take note that even when you have the HDR Playback feature enabled on your computer, you still need a display that supports it. To make sure that your display supports this feature, you can use the DirectX Diagnostic Tool to have the display correctly wired and have the latest WDDM 2.4 drivers installed as well as set the other settings properly. Once you’ve made sure that your computer’s display really supports HDR and you’ve already enabled the HDR Playback feature, now it’s time for you to calibrate. Remember that when you calibrate the display, you should make an external monitor your primary display if you are using it for HDR and then adjust the settings to your liking. And if you are calibrating for primary display, you need to disconnect all other displays.

Follow the given steps below to calibrate the display of your PC.

• Step 1: You need to open the Video Playback first. To do so, navigate to Settings > Apps > Video Playback.
• Step 2: Under the Video Playback settings, uncheck the “Don’t increase display brightness when watching HDR video on battery” checkbox or plug in your PC.
• Step 3: Next, click the “Change calibration settings for HDR video on my built-in display” link located on the right side.
• Step 4: After that, click on the Play button located on the left side to play the video. Then move the sliders to the left or right so you can start to calibrate. Once you see that the quality of the image is to your preference, stop.

Note: Just a tip when calibrating – you just have to find the right balance between the details in the darker parts of a scene. For instance, you have Mountains in the background and buildings in the front – you need to drag the slider to the right to add more details to the snow on the mountain or drag the slider to the left to add more details to the buildings. After that, you can pause the video and exit the full-screen mode. Keep in mind that the quality of HDR depends on you as it is a personal choice. Some users might like a brighter shade while other ones want the darker shade so it really depends on your taste. If you are not satisfied with how your HDR turned out, you can just try calibrating the display again. Simply go back to the default HDR video calibration and click or tap the Reset calibration button. Another thing to remember. First, you can only see HDR content on the full screen and if you’re using a laptop, you need to make sure to watch videos when plugged in and check that the battery settings won't’ lower the brightness.
