One of the essential parts of the Windows 10 operating system is the Microsoft Store as it is the distribution hub of numerous applications such as Netflix, Facebook, and many more. In fact, Microsoft is planning to make it a hub not just for UWP applications but also Windows Classic applications. Microsoft has already built a bridge with the power of Project Centennial which allows developers to migrate and upload their Windows Classic applications to the Microsoft Store. Although the Microsoft Store has been constantly improving, there are still times when you might face an error while using it. One of these errors is error 0x80131500. When you encounter this error, you will get the following error message on your screen:

“Try that again, Something happened at our end, Waiting a bit might help, The error code is 0x80131500 in case you need it.”

To fix this error, you can try changing your internet connection, toggle the date & time settings, change DNS, create a new user account, run the Microsoft Store Apps troubleshooter or reset the Microsoft Store as well re-register it using Windows PowerShell.

Option 1 – Try changing your internet connection

The first thing you can do is to change your internet connection. If you are using Ethernet, you can try to connect to a Wi-Fi connection instead and see if it helps.

Option 2 – Try to toggle the Date and Time settings

The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the error 0x80131500. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.

• Start by tapping the Win + I keys to open the Windows Settings.
• Next, go to Time & Language > Date & time.
• From there, turn the toggle on for the “Set time automatically and Set time zone automatically” option on the right-side panel.
• After that, click on Region & language located on the left side panel and make sure that the Country or region on the right-side panel is set to the country you live in.
• Now close the Settings app and restart your computer and see if it fixes the problem or not.

Option 3 – Try to change the DNS Server

In this option, you can try changing your current DNS settings to the Google Public DNS as it could also help in fixing error 0x80131500. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 4 – Try to create a new Administrator User account

If you have a standard account, you can try creating a new account but this time, you create an administrator user account and then see if the error is fixed or not. Note that you have to sign in with your main account before you can create an admin account.

Option 5 – Run the Microsoft Store Apps troubleshooter

The Microsoft Store Apps Troubleshooter will help you in fixing the error 0x80131500. This is a great built-in tool from Microsoft that helps users fix any app installation issues. So this is worth a try to solve the problem. This built-in tool also helps you fix the Windows 10 Store if it isn’t working. To use the Windows Store Troubleshooter, follow the steps below.

1. Tap Win + I keys again to open the Windows Settings panel.
2. Go to Update & Security and then go to Troubleshoot.
3. On your right-hand side, scroll down to find the Windows Store Apps and then click on the Run the troubleshooter option and see if it fixes the problem.

Option 6 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again and then try to install your app or update your computer again.

Option 7 – Try to re-register the Microsoft Store app via PowerShell

• Tap the Win + X key combination or right-click on the Start button and click on the Windows PowerShell (Admin) option.
• If a User Account Control or UAC prompt appears, just click on Yes to proceed and open the Windows PowerShell window.
• Next, type in or copy-paste the following command to re-register the Microsoft Store app and tap Enter:

powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRootWinStoreAppxManifest.xml

• Wait for the process to be completed and then restart your computer.

Portable small Bluetooth speakers are nothing new on the market, most of the time they have given the opportunity for music listening during picnics and walks in nature and also replaced some car speaker systems. The latest star in small portable speakers in JBL Clip 4, small in size, waterproof, and with an incredible high-quality sound.

Performance and quality

Out of the box and after first look speaker looks great, it has excellent design and is very intuitive to work with. Everything is laid out logically and you can start using it right away without reading instructions.

The sound quality is surprisingly very good and clear. I must say I have not expected this clarity and power from a speaker of this size. The volume range is also incredibly good and will fill most needs even on small picnics outdoors where you can hear it loud enough. One thing to mention is that even on their loudness levels sound is still clear without distortion which, to be honest, is to be expected from someone like JBL.

Where you can take JBL Clip 4

You can take it where ever you want, Its size and clip make it perfect for beach and pool trips. Speaker is waterproof and gas IP67 rating, meaning that sand and dirt will not affect it either. Do not take this speaker to your diving adventures since that will break it but a depth around 1 meter underwater should be safe. After your trip do not forget to wash Clip 4 with clean water so all dirt, salt, and other stuff are properly cleaned for longer life of the device.

How long it will play?

JBL claims that the battery will last 10 hours of continuous play. Note that this is meant probably on the largest volume setting so when you use it on lower settings battery is lasting longer. Playing of course on low volumes will extend playback time even longer but here we come at one feature that I do not like, there is no indication of any kind how much battery is left in the speaker, the only indication is a red light when the battery is almost empty which means you could be outside at that point and did not know that low battery was there in the first place when you were packing. Some battery indication would be a great addon.

More stability for JBL Clip 4

The clip itself has been improved from the previous Clip 3 model, it is wider, it goes all the way around the casing, and feels overall better and more stable. Since the clip is now all around casing this means a wider opening can be made making it fit around stuff Clip 3 was not able to.

Conclusion

All in all, Clip 4 is an incredible speaker and one that would highly recommend, the price goes around 79 USD but it can be found even as low as 50 USD on discounts and promotions and if you manage to get one at that price it is a great buy. Sound is good, portability is great, dirt and waterproof are excellent and battery life is really good.

For a while now, Microsoft has been working hard to add various built-in troubleshooters in Windows 10. In fact, there is a troubleshooter for almost every standard or common error in Windows 10. And now with the newly released Windows 10 v1903, Microsoft has added the Recommended Troubleshooting which allows Windows 10 to automatically fix a lot of critical issues on your computer, and in this post, you will be guided on how you can turn on or off the Recommended Troubleshooting in Windows 10. The Microsoft Diagnostic & Feedback data only provides two settings – Basic and Full. So if you want to turn off the Recommended Troubleshooting for some reason, the only way to do so is to stop it from collecting complete data from your PC. And to turn it on or off, you can choose to switch between them. To do that, navigate to Settings > Privacy > Diagnostics & feedback and from there, select Basic under the Diagnostic Data section. After that, go back to Settings and go to Update & security > Troubleshoot. Once you’re there, you should see a warning message saying, “Share Full Diagnostic data to get additional troubleshooting recommendations”. Based on the message, Microsoft will only offer the recommended troubleshooting based on the Full Diagnostic data which it collects from your computer. On the other hand, if you know how to navigate and use the Windows Registry, then you can enable or disable the Recommended Troubleshooting via Registry Editor but before you proceed, make sure that you create a System Restore point. Once that’s covered, follow these steps:

• Tap the Win + R keys to open the Run dialog box and type “regedit” in the field and tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoft
• From there, look for the key named “WindowsMigration”. If you can’t find it, just right-click on the left pane and create a new key and then name it “WindowsMigration”.
• After that, create a DWORD “UserPreference” and double click on it to set its value to “0” if you want to turn it off or “1” if you want to turn it on.
• Exit the Registry Editor and restart your computer to apply the changes made.

Note: The Recommended Troubleshooting functionality can look into the error logs sent back to the Microsoft team and use an algorithm to set up a solution for you and they’re nothing but Diagnostics and Feedback data that Windows collects and sends back to Microsoft. Moreover, the recommendations are only visible if you are connected to the internet, else it will show the same message.

As you know, Microsoft’s consumer cloud storage platform is none other than OneDrive. It is where users can save any of their files albeit it’s mostly used to store common files like documents and photos. However, there are times when you might encounter some problems when saving these files. Recently, some users reported that they had problems saving Word documents to OneDrive and if you experience the same issue, then you’ve come to the right place as this post will guide you on how to resolve it. According to users who encountered the problem, when they try to save Word documents on OneDrive, an error message appears instead stating, “This is not a valid file name”. This kind of error only occurs when the file is opened from within OneDrive for saving in a different folder. In other words, if the file is saved in the same folder, the error won’t pop up but if it is saved in a separate folder, that’s when the error appears. Worry not though for fixing this error is not complicated and won’t take too long. It seems that this error is due to the 259-character limitation when creating and saving files as far as the Office products are concerned. To resolve it, there are several workarounds you can check out. Before you proceed with these workarounds, make sure that you have a stable internet connection.

Option 1 – Try renaming the file with a shorter name

The first thing you can do to fix the problem is to rename the file with a shorter name. Just right-click on the file and select the Rename option from the menu and then type in the new name and click OK or tap Enter to rename the file.

Option 2 – Try renaming the folders where the file is located

Like what you did in the first given option, all it takes is a right-click but this time on a folder. Rename the folder with a different name and save the changes made and then check if you can now save the Word document on OneDrive.

Option 3 – Try moving the file to a folder with a shorter path

If the first two options didn’t work, you can try moving the file to a folder with a shorter path. Note that it is not the same as doing it locally on a Windows 10 computer so you have to right-click on the file and select the “Move to” option. After that, locate the folder where you want to move the file and select it and then click on the Move button to complete the task.

Option 4 – Try making some changes in the document

You could also try to make some modifications to the document. Once you’ve done that, click the File tab and select the Save As option and then go to the folder where you want to save the file and tap enter.

5 Windows 10 Upgrade Errors

The recently released Windows 10 captivated the mass but its rollout, polished as it might have been, proved everything but seamless. Surf the Internet and you’ll get the gist. People are complaining and they need assistance. Assistance with what you might ask? Many have attempted to make an upgrade but failed after encountering various strange combinations of letters and numbers. These are none other than error codes. If you’ve tried and failed, feast your visuals below as you might encounter one of these 5 Windows 10 Upgrade errors.

Error Code 0x80073712

Encountering error code 0x80073712 in no way implies that you need to throw out your computer system and acquire a new one. Not at all! This error code simply means that a very important file to Windows might have gone missing or corrupted. This file is crucial to Windows update so without obtaining this file, you won’t be able to proceed with the update.

Error Code 0x800F0923

Likely, there are many programs and drivers installed on your computer. They all play a vital role. However, if you’ve received error code 0x800F0923, it might be time to consider or turn your eyes to installed drivers on your system. Why? Error code 0x800F0923 means that there’s a driver or driver on your current Operating System that’s not compatible with Windows 10. There’s clearly a dilemma here.

“We couldn't complete the updates. Undoing changes. Don't turn off your computer.” Or “Failure configuring Windows Updates. Reverting changes”

That’s a pretty odd error but I will say it's slick… That Windows 10 upgrade error is straightforward. Microsoft is just letting you know that they won’t be able to complete the update to Windows 10 and so they are putting your computer back to where it was. How nice of them.

The error messages above are pretty generic and will manifest when the upgrade fails for one reason or the other. To resolve this issue, you’ll most definitely have to decipher what error code was presented. Identifying that will provide a glimpse into exactly what steps you need to take.

The Update Isn't Applicable to Your Computer

I don’t know about you but I strongly believe Microsoft is subtly letting you know that your computer system is old and needs to be thrown out. Also, this update could imply that your PC needs to install important updates to rev you up to the requirements. All relevant updates to your computer must be installed before you can get past this stage.

Error… “Something Happened”

This Windows 10 upgrade error has been the talk of the Internet. In fact, users of Windows OS have been making it a mockery. Clearly, not many have had success after encountering this error. Obviously, “something happened” but it’s just not easy to decipher what went wrong. Microsoft is still trying to figure it out.

As you know, you can find the number keys in two spots on your keyboard – one is above the letters while the second one is at the number pad. Recently, a number of users reported not being able to type any numbers on their keyboards while some reported that their keyboards only type numbers. This issue could occur on both sets of the number keys or on the one at the number pad. This is a rare situation and seldom happens to users. So if you are one of the few who experience the same problem then you’ve come to the right place as this post will guide you on what you can do to fix the keyboard issue. This issue is most likely due to a switched-off number pad, outdated or corrupted keyboard drivers, turned on mouse keys or it might have something to do with the physical connections. Whatever the cause is, here are some options you have to try to resolve the problem.

Option 1 – Try to enable Numlock

The first thing you can do to fix the issue with the keyboard is to enable the Numlock since one of the most common reasons for this kind of problem is where the keyboard won’t type numbers because the Numlock key is disabled. Thus, you have to enable this key by pressing it once to enable the number pad.

Option 2 – Turn off the Mouse key

• From the Start Menu, go to Control Panel.
• Navigate to Ease of Access Center.
• Then select the option “Make the keyboard easier to use”.
• Navigate to the option “Control the mouse with keyboard” and then uncheck the “Turn On Mouse Keys” option to turn off the Mouse key.
• Click on Apply and then on OK to save the changes made.

Note: The problem with the keyboard could stem down to a simple issue in its settings so if you have successfully followed the steps for this solution then you should be able to fix the problem.

Option 3 – Reinstall, update or rollback your keyboard driver

Once you’ve determined that the problem is in the software part of the keyboard, it is now time to try to reinstall, update or roll back your keyboard drivers. To reinstall the driver for your keyboard, refer to these steps:

• From the WinX Menu, open the Device Manager.
• In the Device Manager, you should find your laptop’s keyboard under the “Keyboards” option. Right-click on it and select the “Uninstall” option.

Note: If you’re not quite certain about your laptop’s keyboard, you can uninstall all the keyboards if there’s more than one.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections

You can also try checking if the connection mode you are using for your keyboard is functioning properly. For instance, if you are using a Surface 2-in-device, you can clean the connection pins and see if it resolves the problem.

Option 6 – 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 Keyboard 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.

Error Code 80240020 – What is it?

Users who receive Error Code 80240020 when attempting to install and/or upgrade to Microsoft Windows 10, are receiving the error because the Windows 10 installation folder is either corrupted or unfinished. As a result of this error code, your download and the subsequent update will not process correctly. Users who receive this code do not have to do anything specific, as it might mean that they are attempting to update before their system is ready. These users can simply wait for their computer to prompt them for the update, and then follow the on-screen instructions for the update. However, if a user is seriously wanting to update to Microsoft Windows 10 prior to the prompt, there are ways around error code 80240020. Common symptoms include:

• A dialog box appears with the Error Code 80240020
• Microsoft Windows 10 upgrade is unsuccessful or freezes in the process of updating and displays the error code message.

Solution

Error Causes

This error is only caused by one type of issue, and that is unfinished or corrupted files being present in the Windows 10 installation folder.

• Files that are unfinished in the Windows 10 installation folder are a result of the download not processing correctly, therefore the update is not successful because your computer does not have the files that it needs.
• Files that are corrupted in the Windows 10 installation folder are a result of either a faulty download or preexisting corrupted files that need to be purged.

Until your system is ready to download the new Microsoft Windows 10 upgrade, you will be unable to install the upgrade. As stated, you have the option of waiting for your system to prompt you to download (which means that your system has made the necessary changes to its own files and is ready for the upgrade), or you can use the following steps to correct the issue yourself.

Further Information and Manual Repair

Users and Microsoft Tech Support personnel have discovered three methods to correct error code 80240020. Each of these methods should be attempted by someone who is comfortable with computer software and programs. Anyone who is not comfortable with software should either contact Microsoft Support or wait for their computer to prompt them for the Microsoft Windows 10 upgrade.

6. Once the files are deleted, open and run the CMD as the administrator and type “wuauclt.exe /updatenow”. Press ENTER.
7. Access the WINDOWS UPDATE folder from your control panel, the update and download should resume without further interference from the user.

As with any other error codes, if the above methods do not rectify the issue, it may be necessary to download and install a powerful automated tool to rectify error code 80240020.

Stop C00002lA Fatal System Error- What is it?

C00002lA Fatal System Error is a blue screen of death error that may occur when you start your Windows NT 4.0 based computer. This error causes the screen to turn blue and the system also shuts down. The stop C000021A error message is displayed in the following format:

Stop c000021a {Fatal System Error} The session manager initialization system process terminated unexpectedly with a status of 0xc0000017 (0x00000000, 0x0000000) The system has been shut down.

Error Causes

The stop C000021A error occurs when either Crsrss.exe or Winlogon.exe fails. When the Windows NT kernel identifies that either of these processes has failed, it stops and the error code stop C000021A appears on the computer screen. Here are some of the underlying causes for the stop C0000021A error:

• The incompatible third-party program
• Hard disk issues
• Service pack installation has failed
• Mismatched system files have been installed
• Bad and invalid registry keys

Further Information and Manual Repair

To resolve the stop C000021A Fatal System Error on your PC try the following solutions:

• Remove Incompatible Third Party Programs

If the error occurred after you recently installed a new program, then it is advisable to remove that program. The error occurs due to the incompatibility of the program. To remove the program go to the start menu and click on the control panel. Now click on Add/Remove Program tab and double click on the program name that you recently installed and remove it from the list. Once removed, not reboot your PC. Reinstall a compatible program and run it. It is most likely to resolve the issue. However, if the stop C000021A error still occurs, then it means the problem is critical. It is related to the registry.

• Repair and Restore the Registry

This procedure is slightly long and tricky. To try it, you need to be technically sound. Here’s what you have to do: first create a parallel installation of Windows NT. Start your PC to the parallel installation and then open the Registry Editor. On the Registry Editor’s Windows menu click HKEY_LOCAL_MACHINE on Local Machine and then click Load Hive. Now type the path %systemroot%system32configsystem into the System hive of the prior installation. Then click open. Here you will be prompted to enter the name of the key, type TEST.
