Windows Terminal is a new free Microsoft terminal sort of application. When you open either Power Shell or Command Prompt in Windows they will be opened in different windows, and if you want several of each you will have several windows of each on your screen. Windows Terminal fixes this by opening each of the Instances of Command Prompt and Power Shell as separate tabs inside itself making it much easier to manage multiple instances of named applications. You can also run both Power Shell and Command prompt tabs in the same Windows Terminal. Luckily running command prompt and power shell in different tabs is not the only thing you can do. Windows Terminal lets you choose your own theme, it has emoji support, GPU rendering, split panes, and many more customizable options. Windows 11 will have Terminal as the default command-line environment for opening Power Shell or Command prompt, even Windows Subsystem for Linux (WSL)

Setting Windows Terminal as the default application

If I was successful I have managed to show you that Windows Terminal is something that you should use even if you do not or cannot upgrade to Windows 11. You can use it inside Windows 10 also. First thing is to download and install it. You can get Windows Terminal from the official Microsoft website here: Windows Terminal page After download and installation are completed, open the Terminal app and select the down arrow menu, click Settings. Alternatively, you can use CTRL + + shortcut. Inside Settings by default Default Terminal application would be set to Windows Console Host Click on the Default Terminal application to bring a drop-down menu and choose Windows Terminal from the list. Now by default once opened Windows Terminal will use Power Shell as the default profile, however, you can change this by clicking on the drop-down for the default profile where you can choose between Command Prompt, Power Shell, Windows Power Shell, or Azure Cloud Shell. Pick one that you prefer, click on Save and it will be opened as default on the next run.

Microsoft store is ready and prepared for Windows 11 official release on October 5^th and it is coming with some surprises. It has officially confirmed that many open source and free applications will be in it like Opera, VLC, discord, Libre office, etc. It seems that Microsoft wants to place its store as one place to go for all of your software needs. Another great surprise is the coming of Epic games store implementation. It was officially confirmed but not explained in detail, will we have Epic store opened in Windows store or we will only get installer as a package we will see but this is some great news. As for how it states now, it seems that the Windows store aims to eliminate searching the web for applications and bring them all into one environment with reviews and ratings so you know which one to install and use. It also features a great search engine to find proper applications for your needs. The new store will come to Windows 10 as well but after all Windows 11 has been mostly released and adopted. So expect it via update in two or three months' time. It would be great if some larger companies decide to join MS stores like Autodesk, Adobe, the Foundry, etc so you can install everything you need from it but one can only hope.

Error 0x80070780 is a particularly nasty error since it means we can not access files on our hard drive. This might be an important file from work or anything similar and it can be frustrating when we can access it. In this article, we will address solutions to this error so you can continue with your activities where you have left off.

If you were trying to update your Windows 10 computer and failed due to Error Code 0x80240438, then you’ve come to the right place as this post will give you a couple of suggestions you can check out to resolve this error. You can encounter Error Code 0x80240438 not just in Windows Updates but also in Microsoft Store. This is due to the fact that the delivery mechanism for both Windows Updates and Microsoft Store is common and interdependent. This is why a lot of Windows Update and Microsoft Store error codes are similar. And so fixing them won’t be that hard as well since most methods are basically the same. When you encounter this kind of error in Windows Update or Microsoft Store, you will see the following error message on your screen:

“There were some problems installing updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help – (0x80240438).”

To resolve Error Code 0x80240438, here are some potential fixes you need to check out:

Option 1 – Try to run the Windows Update Troubleshooter

The Windows 10 Store Apps Troubleshooter will help you in fixing the Error Code 0x80240438. 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.

There are times when you encounter problems like Error Code 0x80240438 due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program and Windows Defender Firewall for the meantime and check if it fixes the error or not.

Option 3 – Disable the Proxy server

You can also try to disable the Proxy server for your LAN to fix Error Code 0x80240438 especially if your computer was attacked by some malware or adware recently. In such cases, there is a chance that the malware or adware has changed your network settings in order to generate intrusive advertisements. Thus, you have to disable the proxy server and you can do that by following these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.

“This setting allows you to remove access to Windows Update. If you enable this setting, all Windows Update features are removed. This includes blocking access to the Windows Update Web site at http://windowsupdate.microsoft.com, from the Windows Update hyperlink on the Start menu, and also on the Tools menu in Internet Explorer. Windows automatic updating is also disabled; you will neither be notified about nor will you receive critical updates from Windows Update. This setting also prevents Device Manager from automatically installing driver updates from the Windows Update Web site.”

If you enable this policy setting, you can configure one of the following notification options:

• 0 = Do not show any notifications: This setting will remove all access to Windows Update features, and no notifications will be shown.
• 1 = Show restart required notifications – This setting will show notifications about restarts that are required to complete an installation.
• Now you need to exit the Group Policy Editor and restart your computer for the changes to take effect.

Option 5 – Try resetting the Windows Update folders

Resetting the Windows Update folders can also help in fixing the error in both Windows Update and Microsoft Store. All you have to do is delete the contents in both the SoftwareDistribution folder and reset the Catroot2 folder as well.

Option 6 – Try downloading and installing the Windows Updates manually

Error Code 0x80240438 might be due to a Windows Update that has failed. So if it is not a feature update and only a cumulative update, you can download the Windows Update and install it manually. But first, you need to find out which update has failed, and to do so, refer to the following steps:

• Go to Settings and from there go to Update and Security > View Update History.
• Next, check which particular update has failed. Note that Updates that have failed to install will be displayed under the Status column which has a label of “Failed”.
• After that, go to the Microsoft Download Center and look for that update using its KB number and once you find it, download and then install it manually.

Note: You can also use the Microsoft Update Catalog, a service from Microsoft that provides a list of software updates that can be distributed over a corporate network. With the help of this service, it can be easier for you to find Microsoft software updates, drivers as well as fixes.

Windows 11 has brought some bad reviews for its inability to change the taskbar location to the screen. Luckily we can still hide it if needed. In order to hide the taskbar from the screen follow these simple instructions:

1. Right-click the taskbar itself and select “Taskbar Settings” in the tiny menu that pops up or open Windows Settings and navigate to Personalization > Taskbar
2. Click on Taskbar Behaviors
3. Check the box next to Automatically hide the Taskbar
4. Close settings

As soon as you click on the box to hide the taskbar Windows 11 will apply your settings and hide the taskbar, you will get one line at the very bottom of the screen indicating that the taskbar is still present, just hidden. When you reach the bottom of your screen with the mouse it will pop up and be visible again, just like in all Windows so far.

If you suddenly get a message telling you that “Your Windows license will expire soon, You need to activate Windows in Settings” on your Windows 10 computer but you know that your Windows 10 is already activated. Worry not for this post will help you get rid of that error message right away. Before you get started, make sure that you have the Windows product key with you. If you don’t, you can get it by running the following command in an elevated Command Prompt:

wmic path SoftwareLicensingService get OA3xOriginalProductKey

Take note of the product key and then proceed to the options given below.

Option 1 – Try activating Windows 10 again or use another product key

• If you’re sure that you have the correct product key, click the Go to the Settings button.
• After that, click the Activate button once again.
• If you have another license key, you can also use that as well, just simply click on the Change product key.
• Then enter the new product key and click on Activate. That should fix the problem, if it doesn’t, refer to the next option below.

Option 2 – Try to reset the licensing status

• Click the Start button and then type “cmd” in the Search box and then tap Ctrl + Shift + Enter to open an elevated Command Prompt.
• Next, type the “slmgr –rearm” and hit Enter to reset the licensing status.
• Restart your computer and check if the error is now gone or not.

Option 3 – Try uninstalling the product key and re-enter it once more.

• The first thing you have to do to uninstall the product key is to know the Activation ID of your Windows installation. To do so, open an elevated Command Prompt and type this command, and hit Enter – vbs /dlv
• After you enter the command, you should see the licensing status and Activation ID. And to get all the Activation IDs of all the installed Windows versions, key in this command and hit Enter – vbs /dlv all

Note: The “/dlv” parameter will give you the license information for the installed operating system.

• After you enter the second command, you should see a Windows Script Host window with all the Windows licensing and activation status. Take note of the Activation ID.
• Next, in the same elevated Command Prompt, type this command – slmgr /upk <Activation ID>

Note: In the third given command, “/upk” stands for “uninstall product key”. This parameter uninstalls the product key of the current Windows edition.

• Restart your PC. After that, your computer will be in an unlicensed state so you need to re-enter the product key again.

Option 4 – Try rebuilding the Tokens.dat file.

The issue might be caused by a corrupted Tokens.dat file. The Tokens.dat file is a digitally signed file that stores most of the Windows Activation files so if it is corrupted then no wonder you’re having activation issues. To rebuild the Tokens.dat file, refer to these steps:

• From the WinX Menu, open an elevated Command Prompt.
• After opening Command Prompt, you need to type each one of the following commands and after you type each command, hit Enter.
  • net stop sppsvc
  • cd %windir%ServiceProfilesLocalServiceAppDataLocalMicrosoftWSLicense
  • ren tokens.dat tokens.bar
  • net start sppsvc
  • exe %windir%system32slmgr.vbs /rilc
• Now restart your computer.

Option 5 – Try running the Windows 10 Activation Troubleshooter

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 6 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

As you know, Windows operating system comes with tons of features. Some of which are not intended to be used by normal customers or users directly which means that only a small percentage of the huge user base of the operating system leverages the use of such features. However, they’ve added some major value to the feature list of the operating system. You can find these features under the “Turn Windows Features on and off” option. This indicates that if you want to, you can just type in “Turn Windows Features on and off” in the search box and then enable any feature that you want to enable. Aside from that, there are other ways you can disable or enable the optional Windows Features in your Windows 10 computer.

Option 1 – via Control Panel

• Open Control Panel and select Uninstall a Program.
• After that, select the “Turn Windows features On or Off” option on the left side.

Option 2 – via Command Prompt

• If a User Account Control or UAC prompt appears, click on Yes.
• Next, type in the following command to see the list of the available features.

DISM /online /get-features /format:table | more

• Now all you have to do is copy the name of the feature that you want to enable and for you to do that, you need to execute the following command:

DISM /online /enable-feature /featurename:[Enter the name of the feature here] –All

Note: Now if you want to disable a feature that’s already enabled in your computer, refer to these sub-steps:

• First, you need to check what features are enabled, and for you to find out, enter this command: DISM /online /get-features /format:table | find “Enabled" | more
• And if you want to check the detailed information about a particular feature, you can enter this command: DISM /online /get-featureinfo/featurename:[Enter the name of the feature here]

Option 3 – via Windows Powershell

As you know, the Windows Powershell is a very important tool in Windows 10, and a powerful one at that since you can do a lot of things using this command line. So while you use this tool you need to populate the list of available features first and then you have to download the feature your desired feature.

• Search for PowerShell in the Cortana search box and then run it with administrator privileges.
• Next, type in the following command to populate the list of available features:

Get-WindowsOptionalFeature –Online

• After that, enter the following command to install any feature you want to enable from the list of available features:

Get-WindowsOptionalFeature -Online -FeatureName *Type feature name*

• Now enter the following command to enable your desired feature:

Enable-WindowsOptionalFeature -Online -FeatureName “Type feature name” –all

• And if you want to disable any enabled feature, just enter the following command:

Disable-WindowsOptionalFeature -Online -FeatureName “Type feature name”

Option 4 – via an external installation source

You also have the option to fetch the latest features from an updated offline source. The source could be an ISO any other type of image or just a folder. So you need to decide if you want to use Windows Powershell or Command Prompt.

• If you want to use Command Prompt, just enter this command: exe /online /enable-feature /featurename:< /All /Source:<Enter the path of the feature here>
• If you want to use Windows Powershell, use this command: Install-WindowsFeature –Source “<Enter the path of the feature here>”

Note: If you want to get the latest features, you need to get the latest version of the image of the operating system that you are trying to install the feature from.

As you know, Excel sheet is frequently acclaimed as one of the most useful software that allows users to create spreadsheets, crunch numbers as well as prepare a business report. Usually, tapping the arrow keys to move from one cell to another. However, there are times when you might experience trouble in tapping them – for instance, they won’t work when you tap them. This kind of problem can be quite frustrating since no matter what you do, especially when you tap the arrow keys, instead of a single cell, it moves the entire spreadsheet. If you are one of the users who experience this problem, worry no more for this post will guide you on what you can do to fix it. When arrow keys won’t function as intended in Excel spreadsheets, it could be due to unintended behavior of the Scroll key or it could be related to some issues with the keyboard driver. Whatever the cause is, here are some suggestions you can check out to fix it.

Option 1 – Try to disable the Scroll Lock

The first thing you can do to fix this problem with arrow keys is to disable the Scroll Lock. Although doing this is easy, newer laptops don’t actually come with it so if your keyboard does not come with a scroll key, all you have to do is tap the Fn key and disable Scroll Lock. Aside from that, you could also use the on-screen keyboard to turn off the Scroll Lock. You will see its status on the Excel sheet which will help you to double-check. Moreover, you could also tap the Shift + F14 keys to toggle off the Scroll Lock. To use the on-screen keyboard to turn off Scroll Lock, follow the steps below.

• Tap the Windows key and type “on-screen keyboard” and then tap Enter.
• Once the on-screen keyboard is opened, you should see that the Scroll Lock is on the “On” position since the ScrLk keys are in blue.
• Like pointed out earlier, you can utilize the Scroll Lock indicator located in the status bar as well as disable or enable the scroll key by using this feature on Microsoft Excel.

Option 2 – Try turning on the Sticky key

If disabling the Scroll Lock did not fix the problem, you can try turning on the Sticky Key instead. A lot of users reported that this option fixed the problem for them. So you should try to turn on the Sticky key and to do that, follow the steps below.

• First, type “control panel” in the Start Search and click on Control Panel from the search results.
• Next, select the “Turn On Sticky Keys” option and click on OK.
• After that, go back and uncheck the “Turn On Sticky Keys” option. This should fix the malfunctioning arrow keys on Excel.

Option 3 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to these steps:

• 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.

Option 4 – Update the keyboard driver

You can also update the keyboard driver to fix the problem. There are cases when an outdated or corrupted driver can fix the problem. To do so, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, look for the keyboard driver and click on it.
• Next, right-click on the keyboard driver and select the Update driver option.
• After that, click the “Search automatically for updated driver software” option to proceed.

Option 5 – Reinstall the keyboard driver

If updating the keyboard driver didn’t help, then you might want to reinstall it. How? Follow the steps below.

• Tap the Win + R keys to launch Run.
• Type in 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. Look for the keyboard driver, right-click on it and then select “Uninstall device”.
• After that, unplug the device and restart your PC.
• Then plug your device back in. Assuming your device is connected to your PC, open the Device Manager again.
• Next, click on the Action button and click the Scan for hardware changes button. That should fix the problem

Note: You could also completely uninstall the driver and go directly to the manufacturer’s website and download the latest driver for your hardware and then install it.

Resource hogging is a term when one single application or few of them are taking all system resources for themself causing extreme slow down in the computer and nonresponsiveness. It can be a very frustrating and time-consuming experience and it can cost you money if you can not finish work on time due to this effect. I believe that everyone has experienced at least one slowdown in their IT carrier because of resource-hogging applications and most users do not know how to deal with this. We are here to help you with this issue. Just to be aware that this method shown here is not a method to miraculously speed up your PC or anything similar, this is to be able to detect and recover from extreme slowdowns. Hardware components are still very important and if you can upgrade your computer if it is outdated, please do it because new applications will require a more modern system, and not any kind of tips and tricks will save you from outdated hardware.

Identifying resource hogging app

Now when we got that out of the way let's talk about slowdowns, it is no secret that sometimes an application has bugs and memory leaks that can cause this kind of behavior, and sometimes the application simply takes up too much memory for any other application to work normally. The most simple and straightforward way is to bring up a Windows task manager and inspect running applications and services. You can bring task manager by the key combination of CTRL + SHIFT + ESC If the system is in deep memory deficit you will have to wait for the task manager to open and show itself on-screen. Once opened, click on more details if that view is not opened by default. Once the view expands you will see all running applications with how much RAM memory have they taken and how much CPU they are using.

What to do with app?

Now you are presented with a choice on what to do with the problematic application. If you press the end task button on the bottom right, Windows will kill the application and its processes but any unsaved work inside the application will be lost and unrecoverable in most cases. Or you can try to remove smaller applications running to free up more memory and CPU in order for the computer to catch up. Any choice you make is up to you, but be very careful not to kill Windows essential service by mistake, that will cause immediate system instability with high chances of a system crash.

Some Windows users are encountering the 0x800705b3 error code after failing to install a pending update on Windows 10. Most commonly this particular issue is reported to occur with Integrated webcam drivers updates and Bluetooth adapter driver updates. Follow the guide below in order to fix the issue and update your Windows successfully

Running the Windows Update Troubleshooter

The majority of users that were dealing with this issue reported that the issue was fixed after they ran the Windows Update Troubleshooter and applied the recommended fix.

1. Open a Run dialog box by pressing ⊞ WINDOWS + R. Inside the text box, type ‘ms-settings:troubleshoot’ and press ENTER to open up the Troubleshooting menu. Opening the Troubleshooting tab on Windows 10
2. Once you’re inside the Troubleshooting tab, move over to the right-hand section of the screen and click on Windows Update (under Get up and Running). Next, from the context menu that just appeared, click on Run the Troubleshooter.
3. Once you’re inside the Windows Update troubleshooter, wait until the initial scan is complete and see if a viable repair strategy is found.
4. If the scan has identified a strategy with the potential to fix your ongoing issue, click on Apply this fix and wait until the procedure is complete. Applying the fix Note: Depending on the type of fix that was recommended, you might need to follow an additional set of instructions before the fix will be properly imposed.
5. After you’ve done this, reboot your computer and wait for the next startup to complete.
6. Open Windows Update once again and see if the installation of this pending update is now successful.

Installing the pending Update Manually

Whether you’re experiencing this issue with an integrated webcam driver or with anything else, chances are you’ll be able to circumvent the apparition of the 0x800705b3 error by using the Microsoft Update Catalog to find, download and install the pending update manually.

1. Open your default browser and navigate to the root web page of the Microsoft Update Catalog.
2. Once you’re inside the Microsoft Update Catalog, use the search function (top-right corner of the screen) to search for the update that is failing.
3. After the search is completed and you get the list of results, look for an updated driver version that is compatible with your Windows version and CPU architecture.
4. Once you manage to identify the correct Windows Update, click on the hyperlink associated with the update that you want to install, then click the Download button and wait for the process to complete.
5. After the download is complete, use File Explorer to navigate to the location where you previously downloaded the update.
6. When you get to the correct location, right-click on the .inf file and choose Install from the context menu that just appeared. Note: If you have multiple failing updates with the same 0x800705b3, repeat the instructions above with every Windows Update that you’re having trouble installing.
7. At the end of this operation, reboot your computer and see if the problem is fixed at the next computer startup.

Enabling the Windows Installer Service

The Windows installer service is responsible for installing pending updates that get downloaded by the Windows Update component. If this service is disabled on your configuration, none of the updates waiting to get installed will get completed.

1. Press ⊞ WINDOWS + R to open up a Run dialog box. Inside the text box, type ‘services.msc’ and press ENTER to open up the Services utility.
2. Once you’re inside the Services screen, move over to the right-hand tab of the screen, scroll down through the list of services and locate the Windows Installer service. When you find it, right-click on it and choose Properties from the context menu that just appeared.
3. Once you are inside the Properties screen of the Windows Installer services, access the General tab, click on the Start button to force-start the service. Note: If you can, also change the Startup type to Automatic via the associated drop-down menu. However, depending on your administrator settings, this might not be possible.
4. Restart your computer and wait for the next startup to complete. Once your PC boots back up, attempt to reinstall the driver that was previously triggering the 0x800705b3 error and see if the issue is now fixed.

Performing a Winsock Reset

In case the 0x800705b3 error is related to some kind of network inconsistency (TCP or IP related), you might see Windows Updates failing due to bad data that forces the Windows to abort the installation of new pending updates. In this case, you should proceed by doing a complete Winsock reset procedure to fix the majority of the socket and temporary data-related issues that might cause this behavior. Several affected users have confirmed that this method was the only thing that allowed them to finally fix the Windows Update issue and install pending updates normally. Here are some step-by-step instructions that will walk you through the process of performing Winsock Reset:

1. Open up a Run dialog box by pressing ⊞ WINDOWS + R. Inside the text box, type ‘cmd’, then press CTRL + SHIFT + ENTER to open up an elevated Command Prompt. Accessing an elevated CMD prompt Note: When prompted by the UAC (User Account Control) prompt, click Yes to grant admin access.
2. Inside the elevated CMD prompt, type and taste the following commands in order and press ENTER after each one to effectively reset the TCP and IP data that might be responsible for the apparition of the 0x800705b3 error code:

   nbtstat -R
   nbtstat -RR
   netsh int reset all
   netsh int ip reset
   netsh winsock reset

3. Once every command above is processed successfully, you can go ahead and close the elevated Command Prompt and reboot your computer.
4. After the next startup is complete, repeat the installation of the Windows Update that was previously failing and see if the issue is now fixed.

Performing SFC and DISM Scans

If none of the ‘superficial’ causes have worked in your case, you should start considering some type of system corruption that might affect your computer’s ability to complete pending updates that are currently waiting to be installed. In case you find yourself in this particular scenario, you should run a couple of built-in utilities capable of fixing corrupted instances that might be currently affecting the Windows Update component. Our recommendation is to start with a simple System File Checker scan. An SFC scan will cross-check every Windows File against a local archive that maintains healthy copies. In case corrupted instances are found, this utility will swap the corrupted instance with the healthy equivalent.

Performing an SFC scan

Once the SFC scan is complete, reboot your computer and wait for the next startup to complete. After your computer boots back up, initiate a DISM scan. This utility works differently in the sense that it relies on a sub-component of Windows Update to download healthy copies for the corrupted Windows files that need to be replaced. Because of this, it’s important to make sure that you have a reliable Internet connection before initiating this operation.

Doing a DISM scan

After the DISM scan is complete, reboot your computer one final time and see if the issue is fixed once the next startup is complete.
