Making your own Minecraft server in Windows
Minecraft has taken the world like a storm and if you tried it, you could tell why, procedurally created worlds, various modifications available and fun gameplay are just some of the things this game offers and it is non wonder why kids and adults are enjoying it. Minecraft is even more fun when you play with your friends on dedicated servers, where you all can adventure and build together. Sadly as everything costs, so does the Minecraft servers as well. Lucky you can create your own Minecraft server on your computer so your friends can join and play with you free of charge with just a little time you need to spend reading this guide and building one for yourselves. Without further delay let's dive right into it.

1. Install the most recent Java version

In order to run your personal server, you will need to own and have Minecraft: JAVA edition, not Windows 10 one. If you have this version of the game and it is already running it means that you already have JAVA as well but we will need to check to see if it is the latest version of JAVA, to check this do the following:
  • Press Windows and type in configure java followed by ENTER
  • Under the update tab, click on the update now button
  • If you have the latest version you are all good, if not follow the onscreen instruction on how to update it.
If by any chance you do not have JAVA installed you can get it here.

2. Prepare a dedicated location for your Minecraft server files

You can use any folder you like for your Minecraft server folder but it is highly recommended to create a new folder whose sole purpose will be to hold and run Minecraft server files. this will be very beneficial in the future when server files need to be updated or configured. Having things in one isolated space is always a good idea and keeping things organized is also a good idea.

3. Download, install and start the Minecraft: Java Edition server file

It is now time to download server files, you can get them here. Download the server.jar file and place it inside your server folder. Once everything is downloaded and prepared do the following:
  • Run the server.jar file, the first time it runs, the file will create some configuration files.
  • After additional files appear, there should be a text document called eula.txt. Open it with a text editor then change eula=false to eula=true.

4. Enable port forwarding on your router

This sep is required if you want to have people to play with you that are outside your router network, for example, if you want them to connect to your server from their home. If you do not wish to do this and want only people on your serves from your router network you can skip this step. Unfortunately, to enable port forwarding, you’ll need to make your computer on your local network to be accessible by other computers over the internet via a router. This will effectively make your port to be an open portThis can make your system vulnerable to malicious attacks. Once you’ve enabled it, set the default server port to 25565. You’ll need the Server IP address, which you can get by opening Command Prompt or PowerShell and run ipconfig. Your IP address is usually listed as IPv4 or IPv6 Address.

5. Run the Minecraft server

Simply double-click the server.jar file to run the server. If you want to have more control over it, use the command line.
  • Navigate to your Minecraft server directory using file explorer.
  • We will be using PowerShell instead of Command Prompt to enter commands. Hit Shift + Right-click on the directory window and select “Open PowerShell window here.
  • Once you are in the right directory, write the following command:
java -Xms1024M -Xmx1024M -jar {server file name} nogui
  1. Replace the {server file name} with the full name of .jar file. The command above will make the server run with no Graphical User Interface (GUI) and use 1024MB of allocated RAM space.
  2. If you want to enable the GUI, remove the nogui command. Additionally, you can edit the memory allocation for the server by changing the Xms and Xmx value.
  3. After the server is up, invite your friends to play by sharing your local or public IP address, depending on whether you are using a local or public network. For a local network, you can give the IPv4 or IPv6 Address earlier. For public networks, go to Google and type “what is my ip” to get the address.

A command is not recognized Error in Windows
A command is not recognized Error, what it is? If you are constantly using programs like CMD or DISM directly from the Run prompt, you might have wondered how they launched instantly and how is it that the Windows operating system is able to find them right away. For instance, when you create a shortcut of a program, the shortcut knows where exactly the program is located and launches it quickly. The Windows operating system keeps a list of paths where the most common system programs are located so when you use the Run prompt, it opens easily. The list kept by Windows is called the Windows Environment Variables. If something goes wrong with this list, the programs won’t work. So in this guide, you will be guided on how you can troubleshoot the problem where any command you use is not recognized as an internal or external command, operable program, or batch file. Before you start troubleshooting the problem, you need to make sure that the program you are trying to run really exists. In fact, this can also happen to the Run program which is pulled up using the Win + R shortcut. To check, go to C:\Windows\System32 and there, check if the program exists or not or you can also try searching for the EXE in the System 32 folder. After making sure that the program exists, refer to the instructions given below.

Modify the Windows Environment Variables:

  • Step 1: Tap the Win + X keys and then select System. After that, it will open the section where you can see all the properties on your computer.
  • Step 2: Next, select the Advanced system setting located on the left pane and click on the Environment Variables.
  • Step 3: After that, locate Path under the System Variables and select EDIT.
  • Step 4: Before you edit, you need to copy the entire string and paste it into the Notepad app so that in case something went wrong, you can paste it back.
  • Step 5: Next, look for the directory path, “C:\Windows\System32”. If you can’t find it, try adding a semi-colon at the end.
  • Step 6: Afterwards, click OK to save the changes made and then exit.
  • Step 7: Now restart your computer as all the paths are picked up when your computer restarts.
Note: Now all you have to do is to try executing the programs once again – the ones where you got the error, “ is not recognized as an internal or external command, operable program or batch file” every time you open them and then see if you can now open these programs or not.

Brave and Vivaldi are blocking google FLoC
FLoC is Google’s alternative to third-party cookies and is based on machine learning. This will allow the browser, any browser, to anonymously study how users are browsing and then group them into ‘cohorts’. Following this, you will be served ads based on your cohort and not on your individual data. So, you are still going to be targeted with ads but in a more anonymous manner. Google claims that this will improve user privacy since this “federated learning” happens on the user’s device and artificial intelligence-based learning involves sharing lesser users than what happens with third-party cookies. If something like this gets widely adopted by ad companies and services, it should “protect users” from tracking methods that are more intrusive than third-party cookies, like browser fingerprinting.

Who is against it?

Privacy-focused browsers DuckDuckGo, Brave, and Vivaldi have all warned users against FLoC and have said that they are going to block it on their end. Brave says that Google FLoC has a design that does not respect the customer’s privacy and consent. It has been designed to provide browsing behavior and interest data with any website that users may interact with, and this process does not involve fully informed consent. Vivaldi, another popular Chromium-based web browser, has also made its stance clear regarding the status of FLoC. The company said in a Reddit thread that the FLoC experiment does not work in Vivaldi. It happens because for FLoC to work, some features need to be enabled under the hood, but Vivaldi does not provide those options. The company also added that it plans to stop the entire FLoC component from being a part of the browser, regardless of how Google may implement it. Considering that Brave and Vivaldi have been privacy-focused browsers since their beginnings, the decision to stay away from FLoC is not surprising.

The thing is, the keyboard changes because sometimes we accidentally tap shortcuts like Win key + Space key or Alt + Shift or Ctrl + Shift which changes the keyboard pairs or language. Thus, if your keyboard language changes on its own, there are two ways to resolve it. First, you have to make sure that Windows 10 does not add keyboards without your permission. Second, you have to make sure that the shortcut keys don’t change the keyboard language. This second option is what we’re going to discuss in this post. You need to first set a different input method for each app window. To do that, you have to disable the change in layout. Refer to these steps:
  • Go to Settings > Language and input.
  • Next, type “switching input methods” to open the Advanced keyboard settings with this option inside.
  • After that, select the checkbox labeled as “Let me set a different input method for each app window” and then click the Save button.
  • Restart your computer.
Now that you’ve disabled the change in layout, you now have to find the keyboard settings. Just go to Settings > Devices > Typing > Advanced Keyboard settings. From there, you have the option to select which keyboard is going to be used for any app. When you change the keyboard every time you use an app, usually, Windows remember it so that you won’t have to set it up all over again. In addition, the Advanced keyboard settings page also allows you to override the default input method which could be different from the first one in your language list. Aside from that, there is also a Language bar option that comes in handy as you can quickly switch between keyboards. And if you removed it, you have the option to restore the language bar back as well. Now all that’s left for you to do is to change the Language Settings under the Administrative tab. A user from a forum that came up with this solution, reported that the issue occurred when he started typing in some program with non-Unicode characters which caused Windows to use the default system local language to interpret these characters even though the language is unavailable in the Language bar. To change the Language Settings under the Administrative tab, follow these steps:
  • Go to Settings > Time and Language > Language > Administrative language settings.
  • After that, click on Copy Settings under the Administrative tab.
  • Now make sure that all the Display language, Input language, and Format are English (United States) or any language you prefer.
  • Then mark the two checkboxes in “Copy your current settings to Welcome screen and system accounts & New user accounts”.
  • After that, click OK and then exit.
Note: You also have the option to disable those shortcut combinations which can change your keyboard settings accidentally.

Restoro box imageError Causes

Error code 0xc004fc03 in Windows 10 usually occurs due to issues related to a Windows user’s network. Your computer may be having problems connecting to the Internet or your firewall may be blocking or interrupting your device’s ability to activate Windows 10. In some cases, users may simply need to wait a day or two to reattempt to activate their system using a valid product key, as there may be an issue with the Windows activation servers.  Failure to promptly fix this error code might result in other Windows 10 error messages, such as error code 0xc004f034.

Further Information and Manual Repair

To rectify the error code, Windows 10 users will need to perform manual repair procedures that fix the underlying problems causing error code 0xc004fc03. These procedures may include reconnecting to one’s network, checking your firewall settings, or activating your Windows operating system via phone. The manual repair methods are simple and do not require technical knowledge of the Windows operating system. If your attempts at manually repairing this error code fail, however, you may need to try a few other procedures.

Method One: Verify Internet Connection

To check your Internet connection, you’ll need to access the Network & Internet tab in Windows 10. Follow the instructions below to access this tab and fix Internet connectivity issues if they are preventing you from activating Windows on your machine.

  • Step one: Click the Start button and select Settings
  • Step two: Select Network & Internet
  • Step three: Click the Status section of the Network & Internet tab

If your status shows that you are not connected to a network, you will need to fix your connection. Simply use the Network Troubleshooter to troubleshoot your connection. You will be able to activate your copy of Windows once your connectivity issues are resolved.

If, however, the problem persists and error code 0xc004fc03 occurs during the activation process, this simply means that the existence of the error code is not due to connectivity or networking problems. In such a case, move to the next manual repair method listed below and follow the exact instructions given.

Method Two: Check Firewall Settings

Windows Firewall protects your PC from hackers, worms, and other malicious programs. However, in some cases, it may result in error codes like error code 0xc004fc03. If your firewall is interfering with the Windows 10 activation, you’ll be able to rectify the problem by simply adjusting your settings. Follow the steps below to check – and adjust if necessary – your Windows Firewall settings.

  • Step one: Click search bar and type firewall
  • Step two: Select Windows Firewall
  • Step three: Select Turn Windows Firewall on or off

In some cases, Windows users may not be able to adjust settings within the Windows Firewall tab, as your firewall settings may be controlled by a third party antivirus software. If this is the case, open the antivirus software and turn off the firewall if the software does not prevent you from making such changes to its settings.

Note, however, that you will need to readjust the settings as soon as you activate your version of Windows 10. This is due to the fact that turning off your firewall settings permanently may lead to exposure to worms and other malicious programs.

Method Three: Activate Windows by Phone

Activation of Windows via phone is another option for individuals experiencing error code 0xc004fc03. The activate by phone option in the Update & Security tab will be available once you fail to activate Windows 10. To complete this manual repair method, follow the steps below.

  • Step one: Select Settings
  • Step two: Click Update & security
  • Step three: Select Activate by phone
  • Step four: Follow the instructions provided thereafter.

This is one of the most effective ways to fix error code 0xc004fc03. If the issue persists, however, you can proceed to the last resort.

Method Four: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.
