SmartScreen is a cloud-based anti-phishing and anti-malware component that’s come packed in all Windows 8 (8.1) and Windows 10 versions. This security component is also used in several browsers and programs like Internet Explorer, Microsoft Edge and Outlook.com. Although this program is quite useful, there’ve been reports that SmartScreen is apparently blocking Microsoft’s own apps from opening. According to some users, they only get the “Windows SmartScreen can’t be reached right now” error message every time they try to open apps from the built-in Windows suite like Photos, Mail, Alarms, Maps, etc. Whenever Windows SmartScreen is either down or unreachable on an end-user PC, your computer won’t be able to download anything in both official and unofficial channels. This error might be due to a corrupted Windows account, or it could be that SmartScreen is disabled from the Windows Defender Security Center or it might be down due to an MS issue. In addition, the error might also be caused by a proxy entry.

Option 1 – Make sure that SmartScreen is enabled

Before anything else, the first thing you must do is to check if SmartScreen is even enabled as it might be the reason why you’re getting the error. You can verify this by simply going to the Windows Defender Security Center. To do so, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “ms-settings:windowsdefender” in the field and hit Enter to open the Windows Defender Security Center.
• After that, click on the Open Windows Defender Security Center button located under Windows Security.
• Then click on App & browser control.
• From there, make sure that the Check apps and files toggle is set to Warn and then check the same thing for Microsoft Edge and SmartScreen for Microsoft Store apps.
• If it turns out that SmartScreen is indeed disabled, you have to restart your computer after making some changes and then check if the issue is fixed upon the next startup.

Option 2 – Check if SmartScreen is down for maintenance

Another possible reason why SmartScreen is not working is that it might be scheduled for maintenance. When SmartScreen is scheduled for maintenance, it will become unreachable for a lot of users at the same time and so before you go over unnecessary troubleshooting steps, you need to verify if SmartScreen is down for maintenance or not.

Option 3 – Try to disable the proxy server

If applicable, you can try to disable the proxy server to fix SmartScreen. There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. In some instances, certain proxy servers can interfere with the SmartScreen component and cause it to become unusable. However, if you are not using a proxy server, just skip this option and proceed to the next one, otherwise, follow the steps below to disable the proxy server.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “ms-settings:network-proxy” in the field and hit Enter to open the Proxy tab under Settings.
• After that, scroll down to the Manual proxy setup and make sure that the toggle button of the “Use a proxy server” option is turned off.
• Now restart your PC and check if the problem is fixed upon the next startup.

Option 4 – Try to create a new Windows user account

There are some users who were able to fix the problem by simply creating a new Windows user account. Although this solution will make you lose a couple of settings enforced through your user account, it’s actually effective in circumventing the “Windows SmartScreen can’t be reached right now” error. To create a new Windows user account, here’s what you have to do:

• Tap the Win + R keys to open the Run dialog box.
• And then type “ms-settings:otherusers” in the field and hit Enter to open the Family & other people tab under the Accounts menu.
• After that, click on the “Add someone else to this PC” option and then click on “I don’t have this person’s sign-in information.
• Next, insert the user credentials like emails, password, birth date, etc., and then click Next. Take note that if you want to create a new local user account, just click on Add a user without a Microsoft account.
• After you’re done creating the new Windows user account, click the start icon and then click the account icon and choose to Sign out.
• After you’re logged in, check if SmartScreen now works properly or not.

As you know, Windows 10 comes with the option to create Mobile Hotspot for other devices. This allows you to share your Ethernet connection. However, there are times when one of your devices might fail to reconnect to the mobile hotspot again. For instance, you moved out of the Wi-Fi range because you have somewhere to be and whatnot and when you’re back you find that you are now unable to reconnect to the Windows 10 Hotspot or the shared network. Although you can always restart the mobile hotspot to resolve the problem, however, it might only be a temporary fix. So in this post, you will be given options for a much better solution to the problem. This kind of problem seems unusual and does not occur that often. To fix it, you can try to set up DNS on your Windows 10 device and then configure the settings on the mobile device. It seems that what’s happening here is that the mobile device is unable to lock on to the Mobile Hotspot when the IP address changes for some reason.

Option 1 – Try changing the DNS settings on your laptop

In this option, you need to make sure that IPv4 and IPv6 are selected on your Ethernet connection. You also have to change the Preferred DNS server as well as the Alternate DNS server to 8.8.8.8 and 8.8.4.4, respectively. You also have to validate the settings before you exit just to ensure that you’ve entered everything correctly. After that, open Command Prompt and run the ipconfig command and then take note of the IP address, Gateway DNS 1 and DNS 2.

Option 2 – Try changing the Wi-Fi settings on your mobile device

This option should be mostly the same on all your mobile devices. And given that OEMs build their customization and skin, you might have to fiddle around a little to get the settings. Refer to the steps below to change the Wi-Fi settings:

• Go to the Settings of your mobile device and tap on Wi-Fi.
• Then click the Mobile Hotspot connection that you’ve created on your laptop.
• After that, input the password and tap the Advanced options.
• From there, tap on IP settings and select the Static option instead of DHCP.
• Now you have to enter the IP address, Gateway, DNS 1, and DNS 2 of the laptop you’ve taken note of earlier and that’s it.

Note: If you are already connected to the Mobile Hotspot, long press on the Wi-Fi network and select the Modify Network option and then follow the steps given above to change from DHCP to static. Once you’re done, your mobile device should now be able to connect to the Windows 10 Mobile Hotspot all the time.

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.

If you have received a BSOD error message that says, “Tcpip.sys”, read on as this post will show you how you can fix the problem. The “Tcpip.sys” means Transmission Control Protocol over Internet Protocol. It is a library of a set of rules that are used to interconnect different devices all over the internet. The Tcpip.sys file is a driver and if a BSOD error message includes this one, it could only mean that the driver file is corrupted or incompatible with your system or there are some conflicting programs installed in your computer. To fix this error, you can try the following workarounds. Make sure to carefully follow each one of them.

Option 1 – Check for conflicting or incompatible programs by putting your PC in a Clean Boot state

As mentioned, the “tcpip.sys” BSOD error might be caused by some problematic programs that clash with your existing operating system. Several users reported that numerous programs that are supposedly designed to enhance computer performance are causing conflict in the system instead. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• 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” checkbox 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” checkbox.
• 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.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

Option 2 – Disabling Antivirus Software

There are cases when the “tcpip.sys” BSOD error is caused by the antivirus program installed in your computer that’s blocking some essential operations. Because of this, the operating system fails which throws up the BSOD error. As you know, the antivirus program is designed to protect the computer and monitor every action in the system. However, there are instances when the antivirus program gives false positives and shuts down some modules even if it’s harmless. So this could be the case for the “tcpip.sys” error. To verify if the problem is indeed caused by the antivirus program in your computer, you need to temporarily disable it. After you’ve disabled it, restart your PC and then check if the problem’s fixed or not.

Option 3 – Try to update all your Drivers

From time to time, drivers get corrupted or outdated so it’s no surprise that they conflict with the operating system and cause errors like the “tcpip.sys” BSOD error. To fix the problem, you need to update all your drivers especially the network driver since the “tcpip.sys” error is closely related to this driver. Follow the steps below to update your drivers.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.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. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it. After that, you could also check if there’s a new update of the game you’re getting the issue of the black bar.

I do not know about you, but I prefer to set my Windows to be more to my liking and not how Microsoft thinks it should be. Let’s face it, not all users feel comfortable whit Microsoft settings and idea how things should be. One of the things I particularly did not like even in Windows 10 is icons that come by default on my taskbar, now so far, well until the latest Windows 11 update you could remove default taskbar icons the same way as in Windows 10, just right-click on them and unpin, sadly with latest update build on Windows 11 this option has been removed. In order to remove default icons from the taskbar, one must go now to Windows 11 settings and choose from there which one you would like to be placed on it. Of course, this is nothing game-breaking but it still feels strange why the standard option has been removed, it just makes no sense but lately not many things that come from Microsoft do.

If you are having issues with your network connection and you have it configured to DHCP, then you shouldn’t have any issues in figuring your IP address out. If you want to prevent conflicts between network devices and enable their easy management, then you have to set a static IP address in your Windows 10 computer, worry not for this post will show you how it’s done. The IP addresses for computers are usually configured to the Dynamic Host Configuration Protocol or DHCP automatically by the respective router. This is really convenient since the devices instantly connect to your network and through this, you can save yourself the trouble of configuring the IP address for each new device manually. However, there’s a shortfall in the process – the computer’s IP address can change every now and then. Moreover, you might also find it a lot easier to share a printer or configure a Port forwarding when you set a static IP address. There are three ways to do it – you can set it via Control Panel or Windows Settings or using Windows PowerShell. For more details, follow the options provided below.

Option 1 – Set a static IP address via Control Panel

• Right-click on the network or Wi-Fi icon located in the Taskbar.
• Then select the “Open Network and Internet settings” option from the given list of options.
• Next, go to Wi-Fi settings and scroll down until you see the “Related Settings” section. Here, click on the “Change adapter options” link which will open a new window that will direct you to the Network Connections section of the Control Panel.
• After that, right-click on the network connection you want to set a static IP address for and then select the Properties option.
• Then select Internet Protocol Version 4 (TCP/IPv4) under the Networking tab and click the Properties button.
• Now switch the selector to the “Use the following IP address” option and make the entry for the following fields that correspond to your network setup.
  • IP address (Find it using the “ipconfig /all” command)
  • Subnet Mask (On a home network, it is 255.255.255.0)
  • Default Gateway (It is your router’s IP address.)

• Then check the “Validate settings upon exit” option to help Windows check your new IP address quickly as well as the other relevant information to make sure that it’s working.
• Once you’re done, click the OK button and close the network adapter’s properties window.

Option 2 – Assign Static IP address using Settings

• First, click on the gear icon for Settings and select the Network & Internet tab.
• Next, select Wi-Fi > Current connection where you’ll have to select the network connection your computer is connected to.
• After that, scroll down until you reach the IP settings section and then click the Edit button.
• Now click the drop-down arrow when the IP settings window pops up and select the Manual option.
• Now turn on the IPv4 toggle switch and set the static IP address. You also have to set the Subnet prefix length (subnet mask). For instance, if your subnet mask is “255.255.255.0”, then the subnet prefix length in bits should be 24.
• Afterward, configure the Default Gateway address and the Preferred DNS address and then save the changes you’ve made.

Option 3 – Assign the static IP address using Windows PowerShell

• In the Start Search, type “PowerShell” and right-click on Windows PowerShell from the search results to open PowerShell with admin privileges.
• After that, enter this command to view your computer’s current network configuration: Get-NetIPConfiguration
• Next, take note of the following information:
  • InterfaceIndex
  • IPv4Address
  • IPv4DefaultGateway
  • DNSServer

• Once you’re done, execute this command to set a static IP address: New-NetIPAddress -InterfaceIndex 15 -IPAddress 192.168.29.34 -PrefixLength 24 -DefaultGateway 192.168.29.1
• Afterward, change the default gateway with the default gateway address of your network and make sure that you change the InterfaceIndex number with the one that corresponds to your adapter and IPAddress with the IP address you want to assign to your computer.
• Now execute this command to assign a DNS server address: Set-DnsClientServerAddress -InterfaceIndex 4 -ServerAddresses 10.1.2.1
• Finally, save the changes you’ve made and restart 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.

If you are trying to update or upgrade your Windows 10 computer using the Windows Update and suddenly an “Error 0x800f0900” appears, then you’ve come to the right place as this post will help you resolve this Windows Update issue. When you encounter this error, you will see the following error message on your screen:

“There were problems installing some updates, but we’ll try again later. If you keep seeing this and you want to search the web or contact support for information, this may help: 2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4088776) – Error 0X800F0900”

This kind of Windows Update error is most likely caused by some corrupted files in the system. It is also possible that the Windows Database might have become corrupted as well. So if you are currently experiencing this problem, refer to the options given below and see which one of them works best for you.

Option 1 – Try running the DISM Tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt as admin.
• Then type in this command: exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 2 – Try running the System File Checker or SFC scan

The SFC scan or System File Checker is a built-in command utility in Windows that helps in restoring corrupted files as well as missing files that cause several issues in the computer like the Windows Update Error 0x800f0900. It replaces bad and corrupted system files with good system files. 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.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Perform a System Restore

You can also try to perform a System Restore as it can also help you fix the Windows Update Error 0x800f0900. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

Option 5 – Reset both the SoftwareDistribution and Catroot2 folders

You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder. The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.
