Suggested January 2024 How To Block Or Allow A Wifi Network In Windows 10

Block a WiFi Network

In the command prompt window, execute the below command to block the WiFi network. Replace “WiFi Network Name” with the actual SSID or network name.

netsh wlan add




block ssid


"WiFi Network Name"




As soon as you execute the command, said WiFi network will be added to the blacklist filter, and you will be no longer be able to see or connect to it.

netsh wlan delete filter permission=block ssid="WiFi Network Name" networktype=infrastructure

If you don’t remember the actual name, then use the below command. It will list the names of all the allowed and blocked WiFi networks.

Allow a WiFi Network

Just as you can block select WiFi networks and allow all other networks, you can allow select WiFi networks and block everything else. This kind of whitelisting is useful when you want your system to only connect to the networks you trust.

Just like before, open Command Prompt with admin rights and execute the below command to allow a WiFi network. Replace “WiFi Network Name” with the actual SSID.

If you have more networks, then repeat the command while replacing the name to add more WiFi networks to the whitelist filter. Once you are done adding, use the below command to block all other not-whitelisted networks.

netsh wlan delete




allow ssid


"WiFi Network Name"




In the future, if you decide you no longer have the need to whitelist specific networks and block all others, use the below command. It will delete the “deny all” filter and allow all WiFi networks along with the ones in the whitelist.

netsh wlan delete




denyall networktype

Limited Network Connectivity In Windows 11/10

Internet connection availability and access in Windows is indicated via an icon residing on the taskbar. If you see a yellow triangle exclamation mark on Network icon, it may mean that your Windows 11/10/8/7 PC has Limited Network Connectivity. There can, however, be other reasons for this issue. To troubleshoot and resolve this issue, you may try some of the troubleshooting steps listed in this post, and see if any help.

Fix Limited Network Connectivity in Windows

A Limited Network Connectivity message means that you have a weak connection or you have used a wrong passcode. Specifically, this is what it means:

Your computer detects that a network is present and operating. That means that it detects that the network cable is plugged in, or that it was able to connect to a wireless access point. Your computer’s request for an IP address went unanswered.

Many times, the problem appears because of wrong icon mapping. So the first thing you should do if you see a Limited Network Connectivity message is to ensure that all your cables are connected properly and then reboot your router and restart your computer. Turn off your Wi-Fi interface and turn it back on again. Restarting the computer helps reset the internal modem. This will help get rid of the problem in most cases.

In case this does not help or if the issue frequently occurs, see if any of this helps you:

Recreate the Network profile

Reset Winsock

Renew IP address

Run Internet Connections or Network Adapter Troubleshooters

Update NIC driver

Reset TCP/IP

Reset Windows firewall settings

Disable IPv6

Use Network Reset

Restart Network List Service.

1] Recreate the Network profile

Delete the Network profile and re-create it again. To delete it, run command prompt as administrator, type the following and hit Enter:

netsh wlan delete profile name=type-wireless-profile-name 2] Reset Winsock

Reset Winsock. Open an elevated CMD, type the following and hit Enter:

netsh winsock reset catalog

Then turn off the modem and after a minute turn it on again.

3] Renew IP address

IPConfig is a tool built into Windows, that displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol DHCP and Domain Name System DNS settings. If you have a bad IP address, then renewing your IP address this way may help solve your internet problems.

Type cmd in start search and press Ctrl-Shift-Enter to run CMD as admin.

Type the following to let go of the current IP address and hit Enter:

ipconfig /release

Next type the following to obtain a new IP address and hit Enter:

ipconfig /renew 4] Run Internet Connections or Network Adapter Troubleshooters

Run the built-in Internet Connections or Network Adapter Troubleshooter. To access it, navigate to Control PanelAll Control Panel ItemsTroubleshootingNetwork and Internet.

5] Update NIC driver

Reinstall or Upgrade the Network Interface Card or NIC driver to the latest version. Open Devices Manager, expand Network Adapters and update the concerned driver.

6]  Reset TCP/IP

Reset TCP/IP.  If you cannot connect to the Internet, your Internet Protocol or TCP/IP may have been corrupted, and you may have to reset TCP/IP. TCP/IP is one of the core components required by your Windows computer to connect successfully to the Internet. To do this, open an elevated command prompt, type the following and hit Enter:

netsh int ip reset resettcpip.txt 7] Reset Windows firewall settings

Reset Windows firewall settings to default. If this does not help, temporarily disable firewall and antivirus on your PC to find out if that is the cause.

8] Disable IPv6

Disable IPv6 and see if it helps.

9] Use Network Reset

The Network Reset feature in Windows 10 will help you reinstall Network adapters and reset Networking Components to their original settings.

10] Restart Network List Service

This post offers more ideas on how to resolve Network & Internet connection problems.

Exclamation mark on Network icon

If connectivity is limited and if only the local network is available, you will see an exclamation mark over the Network icon or the Wi-Fi icon. If you can connect and do not have Limited Internet Connectivity or if you do not want to be notified of it, you can make Windows not show this exclamation mark.

To disable this yellow triangle exclamation mark overlay icon, launch ‘Run’ dialog box by pressing Win+R in combination. In the empty field there, type regedit and hit Enter to open the Registry Editor. When prompted by UAC hit ‘Yes’.

Navigate to the following key:

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsNetwork Connections

Name it as NC_DoNotShowLocalOnlyIcon.

Close the Registry Editor and restart your computer.

If your version of Windows comes with the Group Policy Editor, Run chúng tôi and navigate to the following setting:

Here enable the Do not show the “local access only” network icon setting and restart your computer. This will disable the No Internet Access notification.

The yellow triangle exclamation mark overlay icon will now not show on the Network icon, even when you have Limited Network Connectivity.

TIP: See this post if your Windows Troubleshooter is not working, does not start, is stuck or closes before completing its job and you see an error message An error occurred while troubleshooting, A problem is preventing the troubleshooter from starting, with Error Codes 0x80070002, 0x8e5e0247, 0x80300113, 0x803c010b.

How To Use The New Network Sniffer Toolin Windows 10

Windows 10 offers an inbuilt Network Sniffer Tool — chúng tôi — to monitor internal packet propagation and packet drop reports. This tool can help you snoop around. The network and help you resolve the cause of network latency, identify impacted applications, and, when used with an additional set of tools, can provide insight into top metrics. In this post, we will show how you can use the new Network Sniffer Tool (PktMon.exe) in Windows 10.

Network Sniffer Tool chúng tôi in Windows 10

PktMon.exe or Packet Monitor is the new network sniffer or network diagnostic and packet monitoring tool. It is located in the Systems folder, which means you can invoke it from the Run or Command Prompt or PowerShell.

If the program reminds you about Netsh Trace Command, then you are right. Netsh Trace command helps you to enable and configure network tracing to assist you when troubleshooting network connectivity problems.

What can PktMon can do?

If you run PktMon.exe Help on the command prompt. Here is what you get:

filter: Manage packet filters.

comp: Manage registered components.

reset: Reset counters to zero.

start: Start packet monitoring.

stop: Stop monitoring.

format: Convert log file to text.

unload: Unload PktMon driver.

And if you want further help on a specific command, then you can run help against that command. Here is how it looks like:

pktmon filter help Commands list Display active packet filters. add Add a filter to control which packets are reported. remove Removes all filters.

PktMon.exe also comes with real-time monitoring and support for the PCAPNG file format.

How to use PktMon to monitor network traffic

Here is an example of how to use it with a simple example.

Create a Filter to monitor a port

Start Monitoring

Export Log into a readable format

This example is assuming that you want to monitor a port number on the computer, which might be having issues often.

1. Create a Filter

The primary option which allows you to monitor traffic is —filter. Using this option, you can create a filter to control which packets are reported based on Ethernet Frame, IP header, TCP header, and Encapsulation. If you run the below-mentioned program, you will get full details on what you can do with the filter.

pktmon filter add help

So coming back to our topic, let’s assume that we are going to monitor TCP port no 1088. It can be a port used by your custom application, which is crashing, and PktMon can help you figure out if the network is the problem.

Open Command Prompt or PowerShell with admin privileges

Create a packet filter using the command: “pktmon filter add -p [port]”

pktmon filter add -p 1088

You can then run the command “pktmon filter list” to see a list of added filters.

To remove all the filters run the command “pktmon filter remove”

2. Start Monitoring

Since this is not an automated program running in the background but works on-demand, you need to start monitoring manually. Run the following command to start monitoring packets

pktmon start --etw - p 0

It will start the monitoring and created a log file at the mentioned location. You will have to manually stop using the “stop” argument to stop the logging, or it will end when the computer shuts down. If you run the command with “-p 0” then it will only capture 128 bytes of a packet.

Log filename: C:Windowssystem32PktMon.etl Logging mode: Circular Maximum file size: 512 MB 3. Export Log into a readable format

The log file is saved into chúng tôi file which can be converted into a human-readable format using the following command

pktmon format chúng tôi -o port-monitor-1088.txt

Having done that, while you open the file in notepad, and read it, to make sense, you will have to use the Microsoft Network Monitor. It can directly read the ETL file.

That said, Microsoft is expected to start rolling out support for real-time monitoring, which was expected in Windows 10 2004 – but I do not see that that option yet.

How To Open Or Run A Jar File On Windows 11/10

What is Java executable JAR file?

A JAR file is an archiving format that not only stores directories and source files and can also be run as executable files. Such Java ARchive files can contain Java class files that will run when the JAR is executed.

While Archiver tools like 7-Zip can extract content from JAR files, but doing that is pointless – we need to execute the files just as we run the EXE files.

How to run a JAR file in Windows 11/10

Since Java or JAR files can’t run on Windows on their own, you need to install the Java Framework or what is popularly called Java. That said, Java files can be dependent on a particular version of Java. So the steps you need to take to open JAR files on Windows 11/10 are:

Download and install Java.

Set the System path

Run the JAVA file

Set Java file association

Establish a file association with Java runtime.

1] Download and install Java Framework

To run a JAR file on Windows, you need to install Java on your system. Go to Java Download Page, and install it. The default will install the latest version only. However, if your JAR file needs a different version of Java, you can download it from here.

Sometimes, an existing older version of Java can cause an issue. So, if you are facing such a problem, make sure to remove the older version first. Use the official Java Remover tool to get rid of it. Then install the latest version.

2] Set System Path for Java

Next, you need to set the JAVA_HOME path. It ensures that any JAVA file you run can find the necessary libraries for the program. You can also use the command line to echo the Java path to determine if it is correct.

3] Run a Java or JAR file

If you have a JAR file which is not running on its own, then you can use java JDK to run it. Open Command Prompt, and type java -jar name_of_jar_file.jar. It will execute the JAR file automatically.

4] Set the Java or JAR file association

The last step is to establish a file association with Java runtime. It will make sure that every time you run, you are not asked to select a program that can execute it.

Select ‘Choose another app.’

And then choose Select app from the computer.

You should see ‘Java(TM) Platform SE binary’ listed in this context menu but don’t select it.

Locate the file which can run the JAVA or JAR file which is available in the path we suggested above.

Make sure to check the box which says, “Always use this program.”

Once done, all future JAR files will automatically open with Java run time library. You should see the Java icon for all of these files.

How run Java JAR from command line?

You’ll need to use the java command to run a .jar file

If you don’t have java installed, you can fix that by installing the default-jre package.

We hope these tips were easy to understand and were of help to open or run a Java file on Windows 11/10.

How To Disable Startup Services On Windows 11 Or 10

If you no longer need a service to run at startup, suspect it is malware, or prefer it to run only when you need it, you can disable it. Here’s a quick tutorial on how to disable services from running at startup on Windows 11 or Windows 10.

See also: 30+ Windows 11 Services to Disable for Gaming Performance

A Windows service is a program that operates in the background to make things work. Similar to startup programs, there is a list of services that will run during the startup of your Windows PC. Most of these services are important and mandatory for Windows to work.

However, some programs have their own services set to run during Windows startup and continue to run in the background as you use your computer. These services are usually required for their corresponding programs or software to work properly. This is also why, even after you’ve stopped a program from running at startup in Task Manager, that particular program would still run during startup because it has a corresponding service that automatically starts it up.

Disabling a service that a program relies on will cause the program to stop working or give errors when you run it. While some of these services can be malicious or unknown, it’s best to uninstall the corresponding program that you suspect to be the culprit of your problem than to disable its service.

If you insist on disabling a service from running at startup, make sure that particular service is not a Microsoft service that Windows relies on to function properly. If you accidentally disable any of these crucial Windows-related services, you could possibly brick your Windows. But don’t worry, we will show you how to hide the sensitive Windows-related services in the tutorial below so that you don’t accidentally disable any of them.

To stop any service from running at startup on Windows 11/10, follow these steps:

Go to start menu (or press Win+R keys), type in MSCONFIG and open it.

Recommended: Check the checkbox that says “Hide all Microsoft services“. Doing so will hide all sensitive and important Microsoft services so that you don’t accidentally disable any of them and end up bricking your PC.

To disable a service from running at startup, simply uncheck the checkbox next to its corresponding service.

Services listed in the MSCONFIG window are all the services that would run at startup on your Windows PC. Usually, you will know what a service does by looking at its corresponding manufacturer. For example, if you have Apple devices and iTunes installed on your PC, you should be able to see several services related to it with the manufacturer shown as Apple Inc.

Before disabling any service, it’s important to understand what it does and how it affects your system. You can usually find this information by looking up the service name online. Microsoft’s Service Database is a good place to start.

Another way to determine which services to disable is to use the Task Manager’s “Startup” tab. This tab lists all the programs that start with Windows and provides information about their impact on system performance. If a program has a high startup impact, disabling its associated service may help improve system performance.

While MSCONFIG is a useful tool for managing startup services, there are other ways to do it as well. One alternative is to use the Services app, which provides a more detailed view of each service and its properties. To open the Services app, type “services.msc” into the Start menu or Run dialog box.
