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 port. This 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

5. 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.
6. 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.
7. 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.

As you know, one of the most popular browsers these days is the Google Chrome browser. Browsing the web every day using your Chrome browser, leaves a trail of browsing history. Google uses the browser history to streamline and make the browsing experience a lot better. But there are times when Chrome users experience trouble in deleting their web browsing history, data, cookies, and cache. In this post, you will be guided through specific settings that will help you in getting rid of the browsing history in Chrome. There are several options you can take in clearing the browsing history in Chrome. But before you try them, you can try the basic one first using the following steps:

• First, click on the three-dotted icon and click on History from the menu.
• Next, click on the Clear browsing data option and select “All time”.
• Then select the type of history you want to delete.
• After that, click on the Clear Data button.

If clearing the browsing history in Chrome the old way didn’t work, then you can try to check out the options provided below.

Option 1 – Clear the cache using the File Explorer

The first thing you can do is to clear the cache by using File Explorer. To get started, refer to these steps:

• Tap the Win + E keys to open File Explorer.
• Next, navigate to the following paths:
  • C:/Users/YOURUSERNAME/AppData/Local/GoogleChrome/User Data/DEFAULT/Cache
  • C:/Users/YOURUSERNAME/AppData/Local/GoogleChrome/User Data/PROFILENAMECache
• From the given locations above, replace “YOUR USERNAME” with the user profile name you use and then search for a file named “Cookies”.
• Now delete its contents.

Option 2 – Reset Chrome

Resetting Chrome can also help you fix the error. This means that you will be restoring its default settings, disabling all the extensions, add-ons, and themes. Aside from that, the content settings will be reset as well and the cookies, cache, and site data will also be deleted. To reset Chrome, here’s what you have to do:

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome.

Option 3 – Try to clean reinstall Chrome

There are instances when programs leave files behind after you’ve uninstalled them and the same thing can happen to Chrome so before you reinstall Chrome, you have to make sure that you have deleted the User Data folder. To do so, refer to the following steps:

• Hit the Win + R keys to open the Run dialog box.
• Next, type “%LOCALAPPDATA%GoogleChromeUser Data” in the field and hit Enter to open the User Data folder.
• From there, rename the default folder and name it something else, e.g. “Default.old”.
• After that, install Google Chrome again and check if the issue is now fixed.

There are times when an IT admin has to set up multiple IP addresses to the same network adapter. Setting up multiple IP addresses in scenarios like hosting various SSL sites, speed up traffic exchanges can help in avoiding being blacklisted in the SPAM filters, and so on. So in this post, you will be guided on how exactly you can assign multiple IP addresses to the network adapter in your Windows 10 computer. There are several ways to assign multiple IP addresses in a network adapter. You can do it using the Network Adapter settings or using the Netsh utility, as well as the Windows PowerShell utility. To get started, refer to each one of the options provided below.

Option 1 – Assign multiple IP addresses via Network Adapter settings

• Go to Settings first and from there, select Network & Internet, and then click on the Change adapter options. This will show you a list of both the physical and virtual network adapters in your computer.
• Next, double click on the Ethernet adapter where you want to assign the multiple IP addresses and then click on the Properties button.
• After that, you should see the Ethernet properties where you have to select the “TCP/IPv4” or “TCP/IPv6”.
• Once done, click on the Properties button and then select the “Use the following IP address” option under the General tab.
• Now you have to add an IP address, subnet, and default gateway to the network adapter and then click on the Advanced button.
• This will open the Advanced TCP/IP settings where you have to click on the Add button so you can add an IP address. From here, you can keep adding multiple IP addresses to the network adapter. You also have the option to add multiple gateways or DNS IP addresses.
• Once done, if you execute the “ipconfig” command, you should see all the secondary IP addresses listed.

Option 2 – Assign multiple IP addresses using the Netsh command

Another way to assign multiple IP addresses to your network adapter is via the Netsh command.

• In the Start Search, type “command prompt” and from the search results that appear, right-click on Command Prompt and then select the “Run as administrator” to open it with admin privileges.
• If a User Account Control or UAC prompt pops up, just click on Yes.
• After that, run this command: Netsh int ipv4 add address name="Local Area Connection" 192.168.100.100 255.255.255.0 SkipAsSource=True

Note: You have the option to set “SkepAsSource” since it depends on your needs using the Netsh command. When it is configured as true, the IP address won’t be used by the OS for outbound connections.

Option 3 – Assign multiple IP addresses via Windows PowerShell

• Tap the Win + X key combination and click on the “Windows PowerShell (Admin)” option.
• After opening Windows PowerShell as admin, use the NetIPAddress command so you can add more IP addresses. Execute this command: Get-NetIPAddress | ft IPAddress, InterfaceAlias, SkipAsSource
• Next, assign an IP address to a network adapter by executing this command: New-NetIPAddress –IPAddress 192.168.100.100 –PrefixLength 24 –InterfaceAlias “vEthernet” –SkipAsSource $True
• Now to modify the “SkipAsSource” parameter, use this command: Get-NetIPAddress 192.168.100.100 | Set-NetIPAddress -SkipAsSource $False

If you have multiple products with Windows on them, Copy & Paste text between them is easy as 1,2,3 and we will be happy to tell you how can you do it. Hello and welcome everyone, today we will see how can we share text information between 2 devices using Windows 10 in instant. In order for you to be able to share text information between devices, there are two prerequisites that you must meet. The first is that all devices must be connected to the internet, the second is that you must have a Microsoft account. If you have both of these things continue with the tutorial, if you do not have a Microsoft account go to Microsoft website and create one for free. Also, know that this option needs to be turned ON on all devices in order to work. So steps we will explain will have to be done on each device, if you already have some device logged in and connected to Microsoft account, you can skip setting it up. Click on ⊞ WINDOWS and click on settings. Then click on System. Once you are in the system, on the left tabs find and click on Clipboard. If you are not logged in to your Microsoft account do so on the right panel by locating Sync across devices and click on sign in. When you are signed in click on the option to turn it on. One option is turned ON, you will be greeted with two choices, to copy everything from the clipboard automatically or to choose text which you want to sync and paste it with ⊞ WINDOWS + V. Choose whatever better suits your needs, and you are done. Repeat these steps for other devices and you are done.

When we get ourselves a new USB stick, new hard drive, or any storage device not including optical drives they are usually preformatted and ready to be used out of the box. However, reformating them has several benefits and while we are reformatting we can choose in which file system format we want the memory to be formatted. In this article, we will compare and explore 3 typical and standard format options you can get while formating a new media in Windows 10.

FAT32

The oldest one on the list, coming all the way from DOS days. Great for devices that need to be plugged in different operating systems and for USB flash drives. Its advantages are compatibility with all major operating systems and little memory usage comparing to other ones. However, the file system is limited to file sizes of the maximum capacity of 4GB and partitions can not exceed more than 32GB.

NTFS

First introduced in Windows NT this file system offered slower performance than FAT32 and somewhat limited usability but the main advantages were more stability and fewer errors. Its main advantages are support for files larger than 4GB and partitions larger than 32GB along with the ability for on the file encryption, main disadvantage would be limited operating system usage, NTFS can not be used on systems that work on FAT32 like MS-DOS for example or older versions of Windows. The best usage for this file system is in internal hard disk drives and system drives.

exFAT

New kid on the block, well at least from the perspective of the previous 2. exFAT offers unlimited file sizes and unlimited partition sizes but at a price that is even more limiting than NTFS. Some Linux distributions will require a driver to be installed in order to see the exFAT partition. The best use is in storage, in external hard drives. That's it, 3 major file systems, we hope that you have managed to learn something new today, and remember to drop by tomorrow for more articles about advice, tips, tricks, and troubleshooting.
