Fix Wi-Fi doesn't have a valid IP configuration

In today's time, Wi-Fi is a common occurrence, each household has it, on town squares, there are free Wi-Fi hotspots, etc. But sometimes when relaxing at home WI-Fi can fail on us and stop working. If this happens to you do not lose your mind because we have several troubleshooting help tips and ways to get it back quickly so you can continue with your browsing and using your internet.

wi-fi router

Restart the Router and Computer

Yes, we will start with this typical cliche in IT and tech in general. Surprisingly this method still proves over and over again to be true and effective. Over time some electric components simply start working a little bit differently, electrostatic electricity can accumulate on some parts and they can cause issues. By turning off the device and leaving it for some time you are discharging accumulated electrostatics and placing it again into normal working mode.

Unplug your router and leave it for at least 30s like that, a full 1 min is recommended, and then plug it back. Turn it on and restart your computer in order to reboot addresses.

Reset DHCP

If simple have you tried unplugging it and plugging it back in did not work let us reset DHCP. Click on the start button and type in PowerShell, then click on Run as administrator. Once inside the PowerShell type in the following command followed by ENTER: ipconfig /release and after the command finishes, type in: ipconfig /renew also followed by ENTER key. Try the connection again.

Reset TCP/IP stack

The next thing that we will try if the previous one failed is to reset the TCP/IP stack to eliminate corruption of settings files. Like in the previous step, press Start and type in PowerShell and click on run as administrator. inside type in: netsh int IP reset and press ENTER key. Wait for the process to finish and reboot your PC.

Reset WinSock

WinSock is yet another part of Windows OS that is responsible for network communication and resetting it could solve the issue. Again go to PowerShell as described in previous steps and type in this time: winsock reset and press ENTER. Wait for the process to finish and restart your computer.

Other things you can try

Change TCP IP setting back to automatic if you have set manual Ip address on your computer.

Update your network driver via the manufacturer's website of your network adapter. There is a chance that somewhat updates are available to address some issues discovered.

Factory reset your router on the back by locating the reset button on it and pressing and holding it for around 10s.

Turn off your firewall and antivirus protection in order to eliminate it from blocking your internet access.

Change Legacy to UEFI without reinstalling
There are some new generation motherboards for laptops and PCs that bring in support for both the Unified Extensible Firmware Interface or UEFI as well as the Basic Input Output System or BIOS. The main advantage of UEFI over the traditional BIOS is the fact that UEFI supports a hard drive that has a capacity of more than 2 terabytes. However, the disadvantage of UEFI is that it only supports the x64 Windows operating system versions and that the hard drive is supposed to use the GPT structure. So if your PC is compatible with and supports UEFI and you want to change from Legacy to UEFI, then you’ve come to the right place as this post will guide you on how you can exactly do that without having to reinstall it. There are two ways to change Legacy to UEFI. You can convert MBR to GPT using either the built-in utilities in Windows or using the Recovery Environment. Before you proceed, make sure that your computer fulfills the following prerequisites:
  • Your PC’s motherboard should support both Legacy and UEFI.
  • Your PC should be running at least the 1703 Windows 10 version or newer on an MBR partition.
Once you’ve made sure that your computer covers the aforementioned prerequisites, refer to the given options below.

Option 1 – Convert MBR to GPT via Windows built-in utilities

  • In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
  • After that, execute this command: exe /convert /allowfullOS
  • Now, wait until the process is completed since you can track its process on your screen.
  • Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
  • Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
  • Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Convert MBR to GPT via the Recovery Environment

  • When the message appears on your screen while running Windows Setup, you need to tap the Shift + F10 keys to open Command Prompt.
  • Make sure to run Command Prompt as admin and then execute this command: exe /convert
  • After that, wait until the process is completed. When it’s done, you have to go to the BIOS just like in the first given option above.
  • As mentioned, you can usually find the Boot Mode under Boot > Boot Configuration. Once you’re there, set it to UEFI.
  • Now save the changes made and exit as your computer will restart.

To check the integrity of the Hosts file, refer to the following steps:
  • You have to navigate to this path inside File Explorer: C:/Windows/System32/driversetc
  • After that, look for a file named “Hosts” and right-click on it, and open it with the Notepad app.
  • Next, make sure that you write the block URLs in your computer in the list and then save the file.

Windows keyboard language changes on its own
If you have multiple keyboards, things can get quite tricky. There are times when the keyboard language changes on its own since the keyboard changes while you are typing. 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.

DownSpeedTest Removal Guide

DownSpeedTest is a Browser Toolbar Extension for Google Chrome that allows users to test their internet speed and convert files, however this speed test does not show proper values, nor even close.

Upon installation DownSpeedTest will replace your default New Tab page with its own Search Engine “MyWay.com” or “Search.MyWay.com”. This Search Engine camouflages itself as a “Enhanced Google Search Engine”, but all it does is allow more room for easier ad injection. In the background, this extension monitors user browsing behavior and records visited links, viewed products, clicked links and time spend on websites. This information is later used for Ad targeting.

While browsing the internet with this extension enabled you will experience additional ads, sponsored content, and even pop-up ads on some occasions. Due to its information mining behavior and aggressive ad placement, DownSpeedTest had been marked as a Browser Hijacker and it is recommended for removal.

About Browser Hijackers

Browser hijacking is a type of unwanted program, commonly a web browser add-on or extension, which causes modifications in the browser’s settings. There are lots of reasons why you may experience a browser hijack; but commercial, advertising and marketing are the major reasons for their creation. These are typically used to force hits to a specific site, manipulating web-traffic to generate ad-revenue. Even though it might appear naive, these tools are made by malicious people who always try to take full advantage of you, so that hackers could earn money from your naive and distraction. In a worst-case scenario, your browser could be hi-jacked to download malicious software that can do a lot of damage to your laptop or computer.

How one can know whether the browser is hijacked?

When your web browser is hijacked, the following might happen: your browser’s homepage has been reset to some unknown webpage; new bookmarks pointing to porn websites have been added to your bookmarks; the default browser configurations are modified and/or your default web engine is altered; you see unwanted new toolbars added; unstoppable flurries of pop-up ads show up on your computer screen; your browser gets slow, buggy, crashes regularly; you can’t navigate to specific internet pages, such as security software related websites.

How does a browser hijacker infect a computer?

Browser hijackers infect computers via malicious e-mail attachments, downloaded infected documents or by visiting infected internet sites. They can be included with toolbars, add-ons, BHO, plugins or browser extensions. Also, some freeware and shareware can put the hijacker in your PC through “bundling”. Browser hijackers could record user keystrokes to collect potentially important information leading to privacy concerns, cause instability on computers, significantly disrupt user’s browsing experience, and ultimately slow down the system to a point where it becomes unusable.

How you can fix a browser hijack

One thing you could try to eradicate a browser hijacker is to find the malware in the “Add or Remove Programs” list of the Microsoft Windows Control Panel. It might or might not be there. When it is, uninstall it. However, most browser hijackers are difficult to eliminate manually. Regardless of how much you attempt to get rid of it, it might come back over and over. Amateur PC users should never try for the manual form of removal methods, since it demands in-depth system knowledge to perform fixes on the system registry and HOSTS file. Anti-malware software is really effective when it comes to picking up and eliminating browser hijackers that regular anti-virus application has overlooked. If you’d like to get rid of persistent hijackers effectively, install the top-rated Anti-Malware software Safebytes Anti-Malware. Use a system optimizer (like Total System Care) along with your anti-malware software to fix various registry issues, remove system vulnerabilities, and improve your computer performance.

What To Do If You Cannot Install Any Anti-Malware?

Once you are in Safe Mode, you can try to install your antivirus application without the hindrance of the malicious software. Following installation, run the malware scanner to get rid of most standard infections.

Download the anti-malware program using a different browser

Web-based malware could be environment-specific, aiming for a particular web browser or attacking particular versions of the browser. If you’re not able to download the security program using Internet Explorer, it means virus is targeting IE’s vulnerabilities. Here, you should switch over to an alternative web browser such as Chrome or Firefox to download Safebytes Anti-malware software.

Install anti-malware on a thumb drive

Another solution is to save and operate antivirus software tool completely from a Pen drive. Follow these steps to use a USB flash drive to clean your infected PC. 1) Make use of another virus-free computer to download Safebytes Anti-Malware. 2) Insert the USB drive on the same system. 3) Double click on the downloaded file to run the installation wizard. 4) Choose the USB flash drive as the location for saving the software file. Follow the instructions to complete the installation process. 5) Now, plug the USB drive into the corrupted computer. 6) Double-click the Safebytes Anti-malware icon on the pen drive to run the application. 7) Run Full System Scan to identify and clean-up of all types of malware.

Fix Windows Activation Error 0xC004F212
Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:
“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”
Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:
  • Go to Settings and then select Activation.
  • After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.
The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.
  • Extract the Windows 10 ISO files using an extractor.
  • Then browse to the folder you created and go to the sources folder.
  • From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:
[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
Note: “xxxxx” is the KEY to your Windows version.
  • Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.
Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

Fixing the Machine Check Exception Blue Screen Error in Windows 10
BSOD or Blue Screen of Death errors are one of the toughest issues you can encounter in Windows 10 as well as the hardest ones to resolve as they simply shut the system down or restart it abruptly and claims that it isn’t possible to boot Windows again. One of the difficult BSOD errors is the Machine Check Exception BSOD error. The reason why it is hard to fix is that in most cases, it occurs soon after Windows loads which gives users little to no time in resolving it. To make things worse, the system also freezes right before it displays the blue screen error and shuts the system down. Usually, the Machine Check Exception Stop error occurs due to the failure or overstressing of the hardware components. And in the case of almost all Blue Screen of Death errors, the issue usually has something to do with the drivers. So if you frequently see this BSOD error from time to time, now’s the time to act on it by following the solutions given in this post.

Option 1 – Update the Device 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. Look for the device driver you and then select either “Update driver” or “Uninstall device”. 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.
  • If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.
  • Connect the device and Scan for hardware changes – you can see this option under Device Manager > Action.

Option 2 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that can be found on the Settings Troubleshooters page. To use it, refer to these steps:
  • Tap the Win + I keys to open the Settings panel.
  • Then go to Update & Security > Troubleshoot.
  • From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 3 – Try running the System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be causing the Machine Check Exception BSOD error. 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 4 – Run the Startup Repair

In the Blue Screen where the Machine Check Exception error is displayed, tap the F8 key to go to the Startup Settings where you can find Startup Repair and then run it. Note that this is a must-try option especially if you are unable to start your computer and if you can use your computer for a few moments.

Option 5 – Run the DISM tool

There are cases when the Machine Check Exception error is caused by the Windows System Image so you need to repair it using the DISM or Deployment Imaging and Servicing Management tool. The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:
  • Open the Command Prompt as admin.
  • Then type in this command: Dism /Online /CheckHealth
  • Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 6 – Try resetting the BIOS

If you have made some modifications in the BIOS that might have caused this error, you have to revert those changes to resolve the issue. On the other hand, if you have made a couple of changes and you do not remember which is which, you might have to reset the BIOS.

Option 7 – Try resetting Windows 10

To fix this BSOD error, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files.
