As you know, networks that are domain-based are common in organizations and companies. These domain-based networks require multiple computers to be controlled through a single node known as a server. And the one that sets certain policies and restrictions on every system that is joined to the domain is the server administrator. So if you want to add your computer to a domain, you need to have the following information available:

• The domain name
• A user account name that’s registered in the active directory associated with the server
• Windows Enterprise, Pro, or education version

In this post, you will be guided on how you can join or remove a domain. To get started, follow the given instructions below.

Option 1 – Joining a domain

• First, you need to connect your computer to the network associated with the server since your computer and the server have to be on the same network.
• Next, click the Start button and then click on the gear-like icon for Settings to open it.
• After that, navigate to this path: Accounts > Access work or school.
• Then click on Connect. This will open a new dialog box and from there, select the “Join this device to a local Active Directory domain” option.
• Afterward, you will be asked to enter the username and password of your domain account.
• Now select your Account type and when you proceed, you have to restart your computer. Your domain account should now be created.

Option 2 – Removing a domain

• You need to open the Windows 10 Settings app.
• And from there, go to this path: Accounts > Access work and school.
• Next, select the account you want to remove from the domain and then click on Disconnect.
• A prompt will then appear that says, “Are you sure you want to remove this account? This will remove your access to resources like email, apps, network, and all content associated with it. Your organization might also remove some data stored on this device”. Just click on Yes.
• This will give you a Disconnect from the organization prompt.
• Now click on Disconnect and select Restart now to restart your computer. This will complete the removal process of the domain.

Same as in Windows 10, Windows 11 also features a lock screen. IN this lock screen by default, you will see a clock and date above the standard Windows 11 background. Not all users will be happy with this choice but do not worry, you can choose and customize your lock screen to better suit your idea of it.

To personalize the lock screen do:

1. Right-click on Desktop and select Personalize
2. Click on the lock screen
3. Choose one of three options and customize it

   • Personalize Your Lock Screen

     this option will let you set a custom image or slideshow for your lock screen. Choose either one that best suits you. Under selecting picture or pictures for the slide show you can uncheck the option to see tips, tricks, and facts on your lock screen.

   • Lock screen status

     when clicking on this option you can select the application widget that you wish to be shown on the lock screen like weather, mail, calendar, etc. Choose if you would like one by clicking on it.

   • Show the lock screen background picture on the sign-in screen

     as self-explanatory this switch will enable or disable chosen lock screen wallpaper on your login credentials screen.
4. Close settings

All settings will be automatically saved and applied and when you wish to lock the screen easiest way is to press ⊞ WINDOWS + L shortcut on your keyboard.

As you probably know, Windows 10 does not offer lots of choices for its Regional settings depending on where you are and what locale you work with or belong to. The standard region settings for Windows 10 allow users to select one set of formats for the calendar and more. However, this has somewhat changed in the Windows 10 v1809. If you don’t want such a change, you can just override the default regional format settings in the Windows 10 Improved local experience. So in this post, you will be guided on how you can do such a thing. Follow the given instructions below to override the default Regional Format settings in Windows 10. Step 1: Go to Settings > Time and Language > Region. Step 2: From there, the default region is what Windows and apps might use to provide you with local content. However, this won’t be much of use if you work for a different locale and need to have different format settings like Calendar, Dates, Times, Currency, and First day of the week, all of which you can modify under the Regional format. Step 3: You need not reboot your Windows 10 computer after changing. On the other hand, some of the apps will have to close and launch again in order to apply the new format. Thus, if you need to use apps that are of different locales, you will only see the changes after you re-launch the app. Note: You can also select a different language that makes more sense to you. In other words, if you prefer more common words to standard words for your Windows 10 computer, then this is definitely the way to do it. This local format will be used for messages, menus, navigation, settings, and other topics. Step 4: Look for a link that says “Add a Windows display language with local experience packs” under Languages. In case you don’t know, Local Experience Packs are Microsoft Store apps that deliver Windows display language quality improvements. So once you click the link, it will download the packs from the Microsoft Store. In addition, Windows has already begun using AI or Artificial Intelligence as well as neural network-based Machine Learning for Windows localization. And as the number increase, the Machine language improvements and feedback from users will help in making the translations a lot better and make them available to even more languages. All in all, it’s pretty much an interesting and a good move for Microsoft as the demands for topics and machines to be available in local languages have been increasing for the past couple of years.

It is no secret that Fortnite is one of the most played games in the world. Epic has done a great job offering it to plenty of other platforms with cross-play feature meaning that you can play with your friends no matter on what platform they are on. But how Fortnite is a piece of software which is constantly updated and maintained it is pretty normal to have some bugs or issues from time to time. One of the before-mentioned issues is a connection issue or unable to connect to game servers. In our article, we will go through common fixes and solutions in order to get you back in-game as fast as possible. Keep on reading.

Check the Epic Games Status page

Check the Epic Games Server Status page to make sure all systems are operational. If the issue you’re experiencing is related to an outage or system-wide issue, you won’t be able to connect to the Epic Games Launcher or Fortnite until it's resolved.

Use a wired connection

Wireless connections are not as stable as wired connections. This means that the signal can be unreliable and result in packet loss, connection problems, or higher latency or ping. Connect directly to your modem or router with an Ethernet cable to eliminate this possibility and have the fastest connection possible.

Disable your firewalls

Often the quickest way to fix connection problems due to firewalls is to temporarily uninstall and/or disable it.

Windows Firewall disable guide:

1. Click on Start.
2. Click on Control Panel.
3. Click on System and Security.
4. Click on Windows Firewall.
5. Click on Turn Windows Firewall on or off (You might need to provide the Administrator password at this step)
6. Under each Network location, select the Turn off Windows Firewall option

Uninstall any other firewalls

Using a third-party firewall may prevent you from being able to connect to the Epic Games Launcher, Fortnite, or another Epic Games product. We recommend removing any third party firewalls temporarily to see if this resolves your issue. If it does resolve the problem, make sure to add the following executables as exceptions to your firewall:

Epic Games Launcher

• C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win64\EpicGamesLauncher.exe
• C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win32\EpicGamesLauncher.exe

Fortnite

• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping.exe
• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping_BE.exe
• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteClient-Win64-Shipping_EAC.exe
• C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64\FortniteLauncher.exe

Contact your firewall manufacturer for instructions on how to add these as exceptions to it as this varies between them.

Unblock your network ports

Network ports allow certain types of data to be successfully sent over a network that is used by our services. If you have any of these blocked, it may result in you being unable to connect to our games or use our services properly. To unblock your ports on your router do the following:

Windows

First, you will need to get your default gateway and internal IP address:

1. Click on Start.
2. Type cmd and press Enter.
3. Type ipconfig and press Enter.
4. Take note of your Default Gateway and IPv4.

Configuring your router to unblock the ports

1. Open your web browser.
2. Type your Default Gateway into the address bar and press Enter. (A common Default Gateway is 192.168.1.1)
3. You may be asked for a username and password. This varies for each router. Before entering anything, try just hitting OK. If that doesn't work, try the common default username and password below: Username: admin Password: password If these don't work, you can check this website for a list of usernames and passwords based on your router model.
4. Locate the Port Forwarding page in the administration tool and click on it.
5. Make sure you have Port Forwarding selected and not Port Triggering as this is completely different.
6. On this screen, you will need to enter the ports and port ranges below with the correct protocol and local IP of which you took note of above: 80 (TCP/UDP), 433 (TCP), 443 (TCP), 3478 (TCP/UDP), 3479 (TCP/UDP), 5060 (TCP/UDP), 5062 (TCP/UDP), 5222 (TCP), 6250 (TCP/UDP), and12000-65000 (TCP/UDP).

If you have any trouble doing the above on your router, make sure to check out the router manufacturer's support site for additional instructions as these will vary from router to router.

One of the most common ways cybercriminals use to inject suspicious code into devices is by tricking users into installing a malicious program on a targeted device. Oblivious users are vulnerable to such tricks, which is why Microsoft has been working hard in the background to address this issue. Recently, Microsoft announced the availability of a sandboxed version of Windows 10 that runs inside Windows 10 in order to isolate suspected software to run inside it and protect the system from potential threats. This Windows Sandbox feature is a new feature that keeps your computer secure. It is a virtual disposable environment that you can enable. So if suspect any software of being malicious, you can run this software in an environment and ensure that it won’t interfere with any normal processes and would not jeopardize files on your computer. To simply put it, “Windows Sandbox is a new lightweight desktop environment tailored for safely running applications in isolation”. So if the Sandbox is closed, all the residual files, software, and other data are deleted permanently. To enable Windows Sandbox, refer to the instructions provided below. Step 1: You have to make sure that you are running either Windows 10 Enterprise Editions or Windows 10 Pro and that your computer is running build 18305 or newer. Step 2: After that, you have to enable Virtualization to let another instance of Windows 10 running in Sandbox mode. Step 3: Next, search for Windows Features on and off in the search box and then select the appropriate entry. Step 4: From the list, go to the mini window and check the Windows Sandbox and then click on OK. Step 5: Afterwards, in the Cortana Search box, search for “Windows Sandbox” and select the related entry to run it in an elevated window. Step 6: Then from your main computer (host), copy the executable file and paste it inside the Windows Sandbox environment. Step 7: Now run the executable file in the Sandbox environment and use it as you normally do. Step 8: Once you’re done, close the Windows Sandbox application and as mentioned, every data regarding the executable file and the temporary environment will be deleted. Step 9: And for the sake of safety, ensure that there are no modifications made to the host because of the executions in the Sandbox environment. You have the option to contact Microsoft for feedback related to Windows Sandbox. You can use the traditional Feedback Hub if you have any suggestions or any issues. Just fill in the appropriate details and select Windows Sandbox for the feature category under the Security and Privacy section. And if you have any issues related to the execution of and within Windows Sandbox, simply choose “Recreate my problem” then select Start capture to reproduce the issue, and once you’re done, select Stop capture.

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.
