Each time when you press WINDOWS + PrtScn key on your keyboard a screenshot is taken and saved on your Hard drive, to be more precise, it is saved in a specific folder which is in c:\Users\Your user name\Pictures\Screenshots. Now, this specific location is not anything that's bad but it is a little deep and not so user-friendly for quick access.

Luckily this default location can be changed into any folder that you like.

Changing location

First thing is to open File Explorer and then navigate to your PC. Once you go to your PC, go to Pictures, and inside right-click on the Screenshots folder. If there is no screenshots folder inside, this means that since Windows was installed no screenshots were taken with WINDOWS + PrtScn key combination. Please note that just by pressing PrtScn you will create a screenshot but you will place it inside the clipboard ready to be pasted somewhere, with WINDOWS + PrtScn you are saving the screenshot directly in a file on your hard drive.

So once you clicked on the Screenshots folder, go to the bottom and click on properties. Inside properties go to the Location tab. In the location, tab clicks on MOVE and browse to your new location where you would like screenshots to be saved. Once you select the folder for screenshots, click on the Select Folder button and confirm with OK. After this, Windows will ask you would you like to move existing screenshots into the chosen folder. Click YES or NO, depending on your preference.

After this easy setup, all of your new screenshots will be placed now inside the chosen folder.

Thank you for reading and I hope to see you tomorrow. Take care.

If the display of your Windows 10 computer turns on all of a sudden no matter how put it to sleep over and over again, it always wakes up, read on as this post will guide you in resolving this peculiar issue. In case you don’t know, the Windows 10 computer Sleep state is made in such a way that if it’s really important, it wakes up. You may have configured this kind of behavior or there could be some hardware component that’s interrupting its Sleep state. Thus, this post will give you some troubleshooting tips to fix the Sleep state issue caused by the Legacy Kernel Caller. The Legacy Kernel Caller points to the external hardware that’s causing your Windows 10 to wake up even when it’s in a Sleep state. Step 1: Find out what’s keeping your computer from going to sleep. To figure out what really is keeping your computer from going to sleep, you can execute the “powercfg –requests” command instead of checking the power configuration of your computer. This command will look for requests from applications and drivers that prevent the computer from turning off the display or from going to sleep. To execute the command, simply open Command Prompt and type “powercfg –requests” and hit Enter. After that, you will see part of the result that looks like this:

“SYSTEM [DRIVER] USB AUDIO DEVICE An audio stream is currently in use [DRIVER] Legacy Kernel Caller.”

Step 2: The next thing you have to do is remove all the external hardware connected to your computer. In this step, you have to disconnect external hardware from your computer. Based on reports from users who experienced the same issue, the “TV card” is the culprit so make sure you remove that one. Once you’ve removed it, open Command Prompt and run the “powercfg –requests” command again and you’ll see that the “Legacy Kernel Caller” will no longer be on the list. In addition, your computer will get into its regular sleep mode once the hardware is removed. Once you do that, the driver gets hung and won’t release the power request despite being used. Step 3: Try using the request override option The powercfg command also offers a request override option which allows users to disable the requests from applications and services to wake the computer from sleep mode. To run this command, simply open Command Prompt with admin privileges. After you open Command Prompt, type the following command and hit Enter to disable requests from applications and services that causes the computer to wake from sleep state.

Powercfg -requestsoverride Driver "Legacy Kernel Caller" System

Step 4: Check the streaming and media applications You also have to check if your computer is running an audio or video service in the background. In such cases, your computer won’t be able to go to sleep mode if these services are running in the background. You might have noticed that when you play a video or audio, your computer never goes to sleep. And if you have put it to sleep in between watching the video, then it’s probably why your computer is waking up. Thus, you have to stop these services. Step 5: Check the devices that can wake your computer If you didn’t see the Legacy Kernel Caller in the result after you execute the ”powercfg –requests” command, then you can try to execute the following command instead.

powercfg –devicequery wake_armed

After you enter this command, it will give you a list of all the devices that can wake your computer. So if there is anything other than the mouse, keyboard, touchpad, you have to check the power configuration of that device. To do that, go to the Device Manager and disable the device’s “Allow this device to wake the computer” option in its Properties Step 6: Check the Sleep Advanced Settings

• Click on the Windows key and type “control panel” in the field and select the related search result.
• Next, select the Security and Maintenance option and click on the Power Options.
• After that, you have to select the Change Plan Settings but keep in mind that this option is barely readable so you need to read each option carefully.
• Now click on the Change advanced power settings button and a new window will appear.
• Then look for the “Sleep” option and expand it. Make sure that the “Allow hybrid sleep” option is on.
• Reboot your computer and check if your computer now functions properly. If it still didn’t work, you may have to reverse the changes you’ve made.

On the other hand, you could also run the Power Troubleshooter to resolve the Sleep state issue. This built-in troubleshooter will automatically fix any power-related issues in your computer.

Windows comes with a built-in backup solution. However, if it failed because of an internal error, you will encounter an error message saying, “The backup application could not start due to an internal error, Server execution failed (0x80080005)”. When you get this kind of error, it means that it did not start and the process failed with a Server execution error. If you got this kind of error worries not for this post will guide you in fixing the problem in your Windows 10 computer. The Windows Backup service is an excellent feature in Windows that only works on the NTFS file system and if you want to use this make sure that you have formatted your files system to NTFS. It is performed by the Volume Shadow Copy, all you have to do is right-click on any folder and if you see the “Previous versions” option, this means that a backup process runs from time to time and can bring back old files when needed. To resolve the “The backup application could not start due to an internal error”, here are two suggestions you can check out.

Option 1 – Check if the Volume Shadow Copy service is running and restart it

The first thing you need to do is check if the Volume Shadow Copy service. To do that, refer to the following steps:

• Click on Start and type “cmd” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, type “net stop sdrsvc” and hit Enter to execute the command in stopping the Volume Shadow Copy service.
• Next, type the “net start sdrsvc” command and hit Enter to start the service again.

Note: You can also restart the service using the Windows Services Manager.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager.
• From there, look for the Volume Shadow Service (sdrsv) from the list of services. Its Startup type should be set to Manual by default.
• Restart the service and if you don’t encounter any error while you turn it on, re-run the backup service and see if the backup process runs successfully.

Option 2 – Try to run the Volume Shadow Copy Service in a Clean Boot State

If the first option didn’t work and the service still keeps on failing even though the service is running, you can try putting your computer in a Clean Boot State and then try to run Windows Backup again.

• 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.)
• Now try to run the Volume Shadow Copy service again and see if the process goes smoothly.

Note: You might also want to delete all the files in the backup solution if you want to start fresh with the backup solution. Just go to C:/System/Volume/Information/Windows Backup and take ownership of the folder. After that, make sure to stop the Volume Shadow Copy service and then delete all the files inside it.

Error Code 8024402C – What is it?

When upgrading to Microsoft Windows 10, some users may encounter Error Code 8024402C. This error, while attempting to update, is a result of five possible issues. The error code itself is not a critical concern, yet while the error is occurring, users will not be able to upgrade their Windows software. As with any Microsoft error code, even if it is not critical, it is recommended that the error be addressed sooner rather than later. An insignificant error now could lead to a larger, more catastrophic error later on. Common symptoms include:

• A dialog box appears with the Error Code 8024402C when attempting to upgrade to Microsoft Windows 10.
• Your current version of Windows is unable to recognize the need for an update to Microsoft Windows 10.

Recently, a number of users reported that they were not able to run PLEX and other similar streaming services ever since a Windows Update was automatically installed in the system. The error in these streaming services has something to do with a missing Mfplat.dll DLL file from the Windows Media Feature Pack. On the other hand, some users also reported that the mfplat.dll error occurred on several games as well which used the Media Feature Pack. Usually, the mfplat.dll error is caused by the missing Media Feature Pack in Windows 10. Although most of the time the Media Feature Pack is installed by the application that needs it or through Windows Update automatically, there are just certain installers that do not have it. It could be that the Media Playback service was disabled by a particular Windows Update. Aside from that, the error might be because your computer is using Windows 10 N – a Windows 10 version that does not include the Media Feature Pack by default. Whatever the cause may be, you can troubleshoot the problem with the help of the options given below. But before you go on, keep in mind that downloading the missing DLL file and copying it to the folder of the program where you encounter the error won’t really help and will only make things even more complicated.

Option 1 – Install the Media Feature Pack for Windows 10 N version

As mentioned, the Windows 10 N version does not come with Windows Media Player. Meaning to say, the Media Feature Pack is also not installed by default or won’t be updated by the Windows Update component. So if you are not quite sure what Windows 10 version you currently have installed, refer to these steps:

• Tap the Windows key + S and then type “about” in the search box.
• From the search results, click on the “About your PC” to open the About tab of the Settings app.
• Afterward, scroll down to the Windows specifications and check your Windows version under Edition.

Note: If you’ve determined that your computer is using the Windows 10 N version, you need to install the appropriate Media Feature Pack for your computer. How? Refer to the steps below:

• Click this link to download and install the Media Feature Pack from Microsoft’s official website.
• Upon installation, select the edition you want to install using the drop-down menu and then click on Confirm. Take note that there are few reasons why you’d want to install the older version since most streaming services like PLEX and most games usually require version 1803.
• After that, wait until the request is validated. The download should begin in a few minutes automatically.
• Once the download is completed, open the installation executable file and follow the next on-screen instructions to install the Media Feature Pack on your computer.
• Restart your computer. After your computer has rebooted, open the application where you’re getting the mfplat.dll missing error and then check if the problem is now fixed.

Option 2 – Enable Media Playback via Command Prompt

If you encounter the mfplat.dll missing error when you attempt to run PLEX or other similar streaming service and you’ve already verified that the Media Feature Pack is indeed installed, you might want to try enabling it using an elevated Command Prompt. There are cases when a particular Windows Update ends up disabling the feature and creates the grounds which results in the mfplat.dll missing error. Thus, you can have to enable the feature via Command Prompt.

• Tap the Win + R keys to open the Run dialog box.
• Then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• Next, click on Yes if a User Account Control prompt pops up.
• After opening Command Prompt, copy and paste the following command and hit Enter to execute it:

dism /online /enable-feature /featurename:MediaPlayback

• Close Command Prompt and then open the app once again to check if the problem is now fixed.

Option 3 – Try extracting a copy of the mfplat.dll file from the windows.old directory

If you encounter the error shortly after you just upgraded to Windows 10 from an older version, the best thing you can do to resolve the problem is to use windows.old directory to fetch an old copy of the mfplat.dll file. To do so, follow the steps below.

• Go to the Windows drive and then look for the windows.old directory where it preserves a copy of your old operating system as well as associated files in case something goes out of hand during the upgrade process.
• After that, open the windows.old folder and then go to the syswow64 folder.
• Next, from the syswow64 folder, copy the mfplat.dll file and paste it to C: windows syswow64.
• Restart your computer and check if the error is now resolved or not.

As you know, Windows Hello offers you quick access to computers since you can log in to your Windows devices three times faster compared to passwords with the help of the camera via Face recognition and fingerprint reader. This way, Windows Hello will recognize you right away. However, there are also times when you might encounter some problems when using Windows Hello. For one, if you are trying to add the PIN method to Windows Hello on your Windows 10 computer but you suddenly encountered an error code of 0x801c004d or if you are trying to use your existing pin and you encounter an error code of 0x80070490 along with an error message that says, “Not recognized”, then read on as this post will guide you on how you can fix both of these errors. Here is the complete content for both errors:

• “0x801c004d – Unable to enroll a device to use a PIN for login”
• “0x80070490 - Not recognized, Pin and fingerprint are no longer options for signing in”

If you got any of these two errors, there are several potential fixes you can check out to resolve them. You can try to check for any Windows Updates or create the PIN again or check the CNG Key Isolation Service. You could also try to reset the TPM or create a new User Account. For more information, follow the instructions provided below.

Option 1 – Try checking for any available Windows Updates

The first thing you can do is to check for any available Windows Updates. It is possible that your computer may be outdated and is the reason why you’re having troubles with Windows Hello. To check for Windows Updates, just go to Settings and from there, head over to the Update and Security section and click on Windows Updates located on the left pane, and then click on the Check for Updates option. Wait until the process of checking updates is completed and if it finds new updates, install it. After you install the new Windows Updates, check if you can now add the PIN on Windows Hello or not.

Option 2 – Try creating the PIN again

The next thing you can do is to create the PIN again by signing out and signing in again and then try creating the PIN once more. If this does not work, you can try restarting your computer and creating the PIN again. You could also try removing the PIN and then change it.

• Remove the PIN by going to Settings > Accounts > Sign-in options.
• From there, go to the PIN section and click on the Remove button.
• You will be asked to verify your account to proceed in removing the PIN, enter your credentials.
• Restart your computer and then set up a new PIN.
• Once you’re done, restart your computer and check if the error is gone now.

Option 3 – Try checking the CNG Key Isolation Service

The CNG Key Isolation Service is the one that stores and uses long-lived keys in a secure process complying with the common criteria requirements and it is possible that the error could be related to this service. This service is hosted in the LSA processes and provides key process isolation to private keys and associated cryptographic operations as required by the common criteria. Thus, you need to check this service to see if it’s the one that’s causing the error.

• Tap the Win + R keys to open the Run dialog box and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, locate the “CNG Key Isolation Service” and once you find it, double click on it to open its Properties box.
• After opening its Properties, check its Startup type and select Manual. This is the default setting and if it is Disabled, then it’s no wonder why you’re getting errors with Windows Hello, thus, you need to enable it.
• Once done, restart your computer and check if you can now add the PIN to Windows Hello. If you still get the error, then you might want to try setting the CNG Key Isolation Service from Manual to Automatic and then click on the Start button and see if it fixes the error or not.

Option 4 – Try to reset the Trusted Platform Module or TPM

You might also want to try resetting the Trusted Platform Module or TPM to fix the error. You can do this by opening Windows PowerShell and then executing the “Clear-Tpm” command. After that, check if the error is now resolved.

Option 5 – Try to create a new User Account

You could also try to create a new User Account on your Windows 10 computer to fix the Windows Hello error. Once you have created a new local user or administrator account in Windows 10, check if you are now able to add the PIN from this newly created user account.

As of late, a number of users reported experiencing a problem where their Windows 10 computers get stuck on Airplane mode for some unknown reason. According to the affected users, they were unable to turn off the Airplane mode which means that their computers are also not able to connect to the internet. One of the possible reasons why this kind of issue occurs is that there could be a bug with the airplane mode or it could also be the doing of faulty network drivers or physical switch that’s turned on, and so on. If you are one of the few users who experience the same issue, then read on as this post will guide you on what to do if your Windows 10 computer gets stuck on Airplane mode. There are a couple of suggestions you can check out to resolve the problem. You can try to check the status of the Radio Management service, flush the DNS cache or you could turn off the airplane mode via system settings.

If your computer has a physical switch to turn on or off the airplane mode, then you might want to check that switch if you have one. Chances are, it could be the reason why you’re unable to turn off Airplane mode on your computer.

Option 6 – Try to make some adjustments in the Registry

• Tap the Win + R keys to launch the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESystemCurrentControlSetControlClass
• From there, edit the registry value of “RadioEnable” to “1”.
• Exit the Registry Editor once done, and restart your computer.

Error Code 0xd0000272 – What is it?

Error code 0xd0000272 occurs when Windows users are unable to activate their operating system. This usually occurs due to activation servers being busy or unavailable and affects Windows 8, Windows 8.1, and Windows 10 users. Common symptoms of the error code include the following:

• Inability to activate Windows operating system
• Message box with error code 0xd0000272

Solution

Error Causes

Windows users affected by error code 0xd0000272 usually receive a message stating that the “activation server is busy or unavailable”. Some users report the error is resolved on its own after a few hours, while others experience activation issues that resolve only after manual repair methods are implemented.

Further Information and Manual Repair

To improve your chances of resolving issues related to Windows activation error codes, use manual repair methods and procedures. These are often successful as they address the issues causing the error codes to occur, whether there be missing or corrupted system files, network connectivity issues, or invalid product keys.

As you already know, the Windows Sandbox is one of the new features in Windows 10. However, just like other new features, it also throws up errors and one of them is the error that states,

“Windows Sandbox failed to start, Error 0x80070057, The parameter is incorrect”.

This particular error in Windows Sandbox occurs due to its dependence on numerous components of Windows 10 that are related to Hyper-V and Virtualization mainly. To fix this error, there are several options you can check out. You can try to install any pending updates on your Windows 10 computer, as well as make sure that all the services related to Windows Sandbox are enabled.

All you have to do is go to the Windows 10 Settings app and then go to the Windows Updates section and click on the “Check for updates” button to check if there are any pending updates that are needed to be installed. This could fix the Windows Sandbox error.

Option 2 – Ensure that all the supporting processes and services are running properly
