ERR_CERT_COMMON_NAME_INVALID error in Chrome
In case you don’t know, when you visit a website that uses HTTPS, it also offers an SSL certificate to the browser in order to verify the website’s identity. Although it may contain lots of things inside it, one of them is the URL of the website. So if the certificate does not match the URL to what you entered, you will most likely get the “Server’s certificate does not match, ERR CERT COMMON NAME INVALID” error which indicates that the connection is not private and the site may try to steal your data but worry not, as this post will guide you in resolving this issue.

Hard drive shows wrong free space
If you are using your computer and you notice that Hard drive shows high space utilization even if you only have a few applications installed on your computer, then you’ve come to the right place as this post will guide you on what you can do to sort this problem. Upon noticing the odd state of your hard drive and you check the actual volume that’s occupied by the apps in your drive and you see that they are not really occupying a lot of space. This kind of issue could indicate that your hard drive is not showing the correct value for the free storage space of the drive-in your Windows 10 computer. This kind of problem could be passed off as a system bug, however, it could also be a serious problem. In fact, as you are aware, there are hidden folders and files in your computer that could be occupying space and since most of them are associated with system applications, you might not realize it unless you thoroughly check the folders.

The most common causes of the issue are as follows:

  1. The system information folder might be utilizing a lot of space. If you wonder where the information for the system restore points is stored, they are stored in the system information folder which in turn is stored in the drive as a hidden file.
  2. An issue with system maintenance could cause the problem.
  3. Malware or some other software might have created an undetectable hidden file.
  4. Space could be occupied by the trashbin folder.
  5. These hidden files could occupy significant space in the folder, thus slowing down the system and impacting its performance. If you face this issue, try our suggestions and see if they help you.
  6. Run ChkDsk
  7. Clear all Junk files
  8. Reduce the space occupied by the system restore points
  9. Run the System Maintenance troubleshooter

Option 1 – Run CHKDSK utility to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.
  • Tap the Win + S keys to open the Search box.
  • Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
  • After opening an elevated command prompt, copy and paste the following command and hit Enter:
CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]
Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.
  • Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
  • If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
  • After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
  • Wait until the process is completed and then restart your computer.

Option 2 – Try to delete the temporary files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.
  • Open Setting > System > Storage from the WinX Menu.
  • From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
  • Next, find a link that says “Free Up Space” and click it to open.
  • After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space: 
    • Windows Upgrade Log Files
    • The system created Windows Error Reporting Files
    • Thumbnails
    • Temporary Internet Files
    • Previous Windows Installation Files
    • Delivery Optimisation Files
    • DirectX Shader Cache
  • Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
  • Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix the error.

Option 3 – Try to reduce the space occupied by the system restore points

In case you don’t know, system restore points actually occupy a significant space in your computer which is stored in the System Information folder. Thus, you need to check the size of this folder and unhide the folders and files and then click on the folder. The size of the folder should be displayed in the right pane of the window. To fix the storage space problem, you could delete all the old System Restore Points as well as Previous versions of files or you could also restrict the disk usage of the System Restore points.

Option 4 – Try to run the System Maintenance troubleshooter

The problem could also be caused by the System Maintenance and to fix it, you have to run the System Maintenance troubleshooter by following these steps:
  • In the Windows Search bar, type “control panel” and double click on Control Panel from the search results.
  • Next, go to this path: Control PanelAll Control Panel ItemsTroubleshootingSystem and Security.
  • After that, click on the System Maintenance troubleshooter to run it.

About Browser Hijackers

Browser hijacking is actually a form of an unwanted program, often a web browser add-on or extension, which then causes modifications in the browser’s settings. Browser hijackers can do a variety of things on your PC. The idea would be to force users to visit certain sites that are looking to increase their visitor traffic and generate higher ad income. A lot of people assume that these kinds of sites are legitimate and harmless but that is incorrect. Almost every browser hijacker poses an actual threat to your online safety and it is important to classify them under privacy risks. They do not just screw up your web browsers, but browser hijackers could also modify the system registry, leaving your computer or laptop susceptible to other forms of hacking.

Browser hijacking signs and symptoms

Signs that your web browser is hi-jacked include: 1. the home page of your web browser is changed suddenly 2. you find yourself regularly directed to some other web page than the one you actually meant 3. The default search page of the browser is changed 4. you find many toolbars in your web browser 5. you see a lot of pop-ups on your computer screen 6. your internet browser starts running sluggishly or displays frequent glitches 7. Inability to navigate to particular sites, particularly anti-malware as well as other security software sites.

How browser hijacker infects PCs

Browser hijackers infect computers through malicious email attachments, downloaded infected documents, or by checking out infected internet sites. They also come from add-on programs, also called browser helper objects (BHO), web browser extensions, or toolbars. Other times you may have unintentionally accepted a browser hijacker as part of a software program package (generally freeware or shareware). Popular examples of browser hijackers include Conduit, CoolWebSearch, Coupon Server, OneWebSearch, RocketTab, Delta Search, Searchult.com, and Snap.do.

The best ways to get rid of browser hijackers

Some hijackers could be removed simply by uninstalling the related freeware or add-ons from the Add or Remove Programs in the Microsoft Windows Control Panel. Sadly, the majority of the software packages utilized to hijack a web browser are deliberately designed to be hard to detect or remove. Besides, browser hijackers can modify the Windows registry so it can be very difficult to fix manually, particularly if you are not a very tech-savvy person.

Can’t remove Bluetooth mouse & keyboard
Windows 10 supports various devices to get connected to which makes it quite a flexible operating system. The connection varies on the fact that the device can be connected either with Bluetooth or other wireless and wired connection. However, no matter how great the features are, there a few times when they bring in some bugs too. One of these bugs won’t allow you to either remove or reinstall the Bluetooth mouse and keyboard device from your Windows 10 computer. So if you are currently experiencing this problem, read on as this post will guide you in fixing it. Before you go over the suggestions laid out below, you need to create a System Restore Point first since, in one of the options, you will be making some changes with the registry files as well as some critical Windows settings. Once you have that covered, refer to the following options.

Option 1 – Configure the Bluetooth Services

The first thing you can do is configure Bluetooth Services.
  • Tap the Win + R key combination to open the Run dialog box.
  • After that, type “services.msc” in the field and hit Enter to open the Windows Services Manager.

    • Bluetooth Audio Gateway Service – Manual (Triggered)
    • Bluetooth Support Service – Manual (Triggered)
    • Bluetooth User Support Service – Manual (Triggered)
  • Now click on the Start button to start all the aforementioned services and then check if you can now remove or reinstall the Bluetooth mouse and keyboard device.

Option 2 – Try running the Bluetooth Troubleshooter

As you know, Windows 10 has various troubleshooters with user-friendly interfaces where you can utilize them to fix issues in your PC. And since you’re dealing with some Bluetooth problem, you have to run the Bluetooth Troubleshooter.
  • Open the Windows 10 Settings.
  • Then go to Update & Security > Troubleshoot.
  • You should find the option for Bluetooth on your right-hand side – click on it then click on the “Run the troubleshooter” option.

Google's Pixel smartphone is one if not the best Android smartphone on the market. It regularly gets updates and Google is really trying to keep it as a top choice for Android smartphone users. One of the new things that Google has released for its smartphone series is a new emergency dialer.

google pixel 6

With an emergency dialer, you will be able to quickly access local contact information for police, fire, and medical services. This dialer is able to contact before mentioned services even when the phone is locked and when you are traveling.

The idea is to quickly access the default emergency number no matter in which country you are currently in, service will find the appropriate number and set it as default so if you need it there is no delay in searching for the appropriate number and dialing it.

Once the service is enabled on the device you can swipe up and tap Emergency call without unlocking your phone or you can press and hold the power button for five seconds and tap Emergency.

If you have a Pixel smartphone go to the Google support page and follow instructions on how to enable this service. It costs nothing and it could potentially even save your life.

Fix Windows Update Error 0x80240034
There are cases when you encounter some issues while updating your Windows 10 computer. One of these issues is the error 0x80240034. This particular error is a Windows Update Error that appears on the Windows Update pane every time an update fails to install. When this happens, your Windows Update will only get stuck at 1% and nothing happens afterward and eventually fails. If you click on the View Installed Update History, you will see the error code 0x80240034 for the failed updates. You will see this error each time you try to update your Windows PC. Take note that this issue doesn’t only happen to a specific version of the Windows Update but on various different Windows builds based on many users. What’s more, is that some users are also seeing a different error code when their Windows Update fails but they still end up seeing the error code 0x80240034 when they check the Windows Update history. At the time of writing, it isn’t determined yet what really causes this error but it’s most likely due to some corrupted files in the computer which is why the most common solution you can try is resetting the Windows Update cache. On the other hand, other users also resolved the issue by using the ISO and selecting the “Do not keep previous settings” option during the Windows Update so it might be something to do with transferring the previous settings through the update client. For clear instructions in fixing this issue, refer to the two options provided below.

Option 1 – Try to clear the Windows Update Cache/Distribution Folder

As mentioned earlier, a lot of users tried clearing the Windows Update cache to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.
  • Step 1: Tap the Windows key once.
  • Step 2: Next, type in “command prompt” in the Windows Start Search, and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
  • Step 3: After opening Command Prompt, type in “net start wuauserv” and hit Enter.
  • Step 4: Then type in “rmdir %windir%SoftwareDistribution /S /Q” and hit Enter.
  • Step 5: Now type in “net start wuauserv” and hit Enter. Once it’s done, try updating your Windows PC again, it should now work just fine.

Option 2 – Update Windows via ISO file

If option 1 didn’t work for you, you can try this second option of updating your Windows 10 computer using an ISO file which means that you will have to create a Windows 10 bootable media and use it to install the latest Windows 10 version. The most user reported that this option works and the reason why it does have something to do with the Windows Update client since the Windows Updates downloaded from the regular Windows Update client seems to create issues such as the error 0x80240034. However, issues like this one don’t occur when the very same Windows Updates are downloaded and installed via an ISO file. Take note that when using a Windows ISO file, you will be asked to choose what you want to do with the previous settings and apps. A lot of users opted for the “Not to keep the old Windows settings” option which has resolved the issue. So if you want to keep the previous settings then you must try to update Windows first while keeping the old settings. However, if it doesn’t work, you have to try installing the latest version of Windows without keeping the previous settings.
  • Step 1: Click this link and then click the Download Tool Now button.
  • Step 2: Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
  • Step 3: Now select the ISO file option in step 5.
  • Step 4: After that, you should now have an ISO file.
  • Step 5: Next, go to the location where you’ve downloaded the ISO file.
  • Step 6: Then right-click on the Windows 10 ISO file and select the Open with an option and then select File Explorer.
  • Step 7: Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either: Nothing (clean install) or Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

Repairing a corrupt Group Policy in Windows
If you recently made some changes in your Windows 10 computer using the Group Policy Editor but they were not reflected and you got errors instead, it could be that your Windows computer wasn’t able to read the Group Policy file (registry.pol). To resolve this kind of issue, you have to repair the potentially corrupted Group Policy using the options given in this post. .As you know, Group Policy is a feature in the Microsoft Windows Active Directory which allows an admin to make changes in the features on Windows PCs that are on the network. So if the modifications you just made weren’t successfully applied, then there could be something wrong with the registry.pol file on the client or it could also be that the Group Policy folder is missing. To fix this issue in the Group Policy, you need to refer to the given suggestions below and make sure that you have admin privileges as you execute them.

Option 1 – Try to delete or recreate the missing registry.pol file

The entire settings of the Group Policy are stored in the registry.pol file so if it went missing, all the changes you make will not be reflected. The good thing is that you can recreate it but if the file exists and is corrupted, you need to delete it first before you recreate it.
  • First, go to the C:/Windows/System32/GroupPolicy/Machine location.
  • And from there, check if the registry.pol file exists or not. If it’s there, just delete it permanently by tapping the Shift + Delete keys.
  • Now it’s time to recreate the file. Just open Windows PowerShell with admin privileges by tapping Win + X + A keys.
  • After opening PowerShell, type this command: gpupdate /force
  • The command you entered will recreate the registry.pol file and will refresh the Group Policy. Restart your computer.

Option 2 – Try recreating the secedit.sdb file

The security settings of Group Policy are stored in the secedit.sdb file so if you made some changes to security and they weren’t reflected, you can try to delete and recreate the secedit.sdb file instead of deleting the Group Policy file. All you have to do is navigate to the C:/WINDOWS/security/Database folder and look for the secedit.sdb file and rename it or move it to another folder. After that, restart your computer. Once your computer has restarted, the secedit.sdb file will be created again.

Option 3 – Try to reset the Group Policy to default

You can also try to reset the Group Policy back to its default state. There are several ways you can do that. You can either use the gpupdate or the secedit command in the Windows PowerShell to do that. Resetting the Group Policy will resolve any issues that could be caused by its current settings.

Option 4 – Try to perform System Restore

System Restore can also help resolve the Group Policy issue. It could be that prior to the issue, you’ve made some changes in the system that might have affected the Group Policy. To undo these changes, perform System Restore.
  • First, tap the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.
  • Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
  • After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Use the DISM tool

You can also try running the Deployment Imaging and Servicing Management or DISM tool. This tool will repair the Windows System Image as well as the Windows Component Store in your Windows 10 computer. So if there are any missing or corrupted folders and files, the DISM tool can restore and repair them. As a result, any system consistencies and corruptions will be fixed. To run this tool, follow these steps:
  • Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
  • After that, input each one of the commands listed below sequentially to execute them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • Dism /Online /Cleanup-Image /RestoreHealth
  • Once you’ve executed the commands given above, restart your computer.
