Installing or updating Google Chrome does not always go smoothly as there are times when it also encounters some errors like the error code 0x80072EE7. This kind of error in Chrome is most likely caused by the Windows Firewall or third-party Firewall (if you’re using one) that blocks the installation or update process. Aside from this known culprit, there are also other factors to consider such as corrupted or incompatible installation files or it could also be caused by some issue with your internet connection. If you face this kind of problem when installing or updating Chrome, you will see the following error message on your screen:

“An error occurred while checking for updates: Unable to connect to the Internet. If you use a firewall, please whitelist GoogleUpdate.exe. (error code 7: 0x80072EE7 — system level).”

Whatever the cause of this error is, you need to use the options prepared below to fix it.

Option 1 – Whitelist the “googleupdate.exe” in Firewall

If the issue is really caused by the Firewall, you need to whitelist the googleupdate.exe program to fix the error. To do that, follow these steps:

• Tap the Win + E keys to open the File Explorer.
• Next, copy and paste the following location in the address bar and tap Enter to go there.

nslookup is a command-line tool that helps in finding the DNS records of a website. It sends a name server query to the DNS and obtains the corresponding IP address. Aside from that, it can also perform some complex functionality such as finding details about FTP server, Mail server and many more but most of them are used by administrators. The best thing about nslookup is that it queries the DNS server directly and it does not rely on the cache. On the other hand, there is another tool called PING that is used to verify connectivity. PING sends a packet of information to the IP address or Domain and gets back a response in the form of packets. So if everything goes well, all packets are received but if not, it will help you find out where the delay in the network exactly is. However, the ping command does not always attempt a DNS lookup which means that it might be using the DNS cache and use the IP address available in that table. Although both nslookup and PING help you in identifying the host or IP address, however, they don’t always work and sometimes fail. So if your nslookup works but ping fails on your Windows 10 PC when querying the IP address of a website then it could be caused by many reasons. It could be that the nslookup queries work for you but when you try to use PING, it fails. For instance, if you open the abc.com website, here’s how it will look like:

nslookup xyz.com Server: dns.company.com Address: 192.168.1.38 C:> ping xyz.com Ping request could not find host xyz.com. Please check the name and try again.

The domain is converted into an IP address and then data is sent to that IP address when you use PING. So when a reply comes back it means that the data is going back and forth to that domain without any problem. However, if the DNS fails to resolve the IP address of the website or if your PC does not attempt a DNS lookup, you will receive a similar error message that says, “Could not find host” and so on. To resolve this issue, here are some options that might help.

Option 1 – Reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the issue with nslookup and PING. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 2 – Force Windows to do a DNS lookup using FQDN

• Go to Settings > Network & Internet > Status > Change adapter options.
• From there, right-click on the network and select Properties.
• Next, in case you’re using IPv6, from the list of connections available in the list, select Internet Protocol Version 4.
• Then click on Properties and click Advanced.
• After that, switch to the DNS tab and select “Append these DNS suffixes (in order)” and click on the Add button and then add “.” as a suffix so that each time you query using PING and another tool, it will add a “.” at the end and will force the lookup.

Option 3 – Make sure that there is only one default gateway

If your computer has more than one NIC connected and there are multiple default gateways, then it will most likely create confusion which is why you need to remove the default gateway from the configuration of all NICs and make sure that there is only one default gateway.

Option 4 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the nslookup and PING issues. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Check the Windows Host file

You can also try to cross-check the Windows Hosts file to find out if the website you are trying to open has been blocked, because if it is, then it’s no wonder why PING fails even when nslookup works. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.

Option 6 – Delete the WLAN Profiles

Deleting the WLAN Profiles might be a good idea if you are not able to connect to the internet on your computer and if you’re using Wi-Fi. It could be that the networks that were connected previously have gone rogue which is why it is not connecting properly. And so deleting the WLAN profiles might help you in fixing the issue with nslookup and PING.

Option 7 – Reinstall the Network Adapter Drivers

• Tap the Win + R keys to launch the Run window and then type in the “msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and select “Uninstall device”.
• Restart your PC.

What is error code 0x80070103?

When visiting the Windows Update Website or the Microsoft Update Website to download the latest update for hardware drives, you could possibly receive Error Code 0x80070103 when clicking on the update driver. This error code occurs when Windows tries to download a piece of identical hardware for a second time. It could also occur when Windows tries to update a currently installed driver to an unsuitable version of that driver.

Solution

Further Information and Manual Repair

There aren’t many ways to handle this issue. Below are two methods of fixing Error Code 0x80070103.

Method 1:

Method 2:

When trying to repair error code 0x80070103, if you find method one hard to follow, can contact Microsoft directly. Call up the help center number listed on their website, and a technician will be able to walk you through the process of ensuring the updater is not attempting to download multiple copies of hardware or trying to install unusable updates on your computer. Because the Windows Updater is set to a generic method of searching for updates, it may not be set to optimize the personal computer's settings. This is why you must select all of the optional update options and why this process is so long. It may be made easier by having a computer repairs technician walk you through it. However, if you want to automate the process of getting that problem solved, you can use a powerful tool to get the job done.

If you recently upgraded your computer or if you’ve just switched to a new Windows 10 PC, the most common errors you might encounter are the Windows Activation errors. This issue boils down to the Windows Activation server which has either failed to validate or recognize the license tied to the digital account. In this post, you will be guided on how to fix an activation error in an organization with an error code 0x8007007B. It contains this exact error message: “We can’t activate Windows on this device as we can’t connect to your organization’s activation server. Make sure that you’re connected to your organization’s network and try again. If you continue having problems with activation, contact your organization’s support person. Error code 0x8007007B.” Various computers are activated via the KMS licensing (Key Management Server) in organizations. Computers that are activated using this process do not get a permanent activation and have to stay connected to the organization instead of for at least 7 months or 180 days. It is common in Pro and Enterprise versions that are deployed in bulk for at least hundreds or thousands of computers. So imagine a user with a personal computer in the office who decided to leave the organization but will still have an activated Windows key. And so to prevent that from happening, organizations use the KMS licensing. Another possible cause of the error is in case some user used an organization key and later on, the PC just got upgraded or downgraded to a version that is not compatible with that copy of Windows. To fix this Windows Activation error, here are some suggestions that might help.

Option 1 – You can try connecting to the organization’s network and activate the computer. But before that, you need to first check if the computer actually belongs to an organization or not.

• Tap the Win + R keys to open the Run dialog box.
• Type “cmd” and hit Enter to open an elevated Command Prompt.
• After that type the vbs /dlv command and hit Enter to execute it.
• Next, check if the Product Key Channel says “GVLK”. If it does, then it means that your computer was activated using volume licensing.

Option 2 – Change Licence Key

If you’ve recently left an organization then it’s best if you buy another copy of Windows 10 and then change the license key. This time, make sure that the license key is for the same version of Windows. However, if it’s different, you need to format your computer.

Option 3 – You can try activating Windows 10 using a mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 4 – If you think that the issue is caused by some hardware changes, you can try using the Activation Troubleshooter.

There are times when users already have the license keys and were able to activate Windows. However, it doesn’t last long and only works for a while and it’s suddenly throwing up an activation error like this one. To use the Windows Activation Troubleshooter, just go to Settings and to Activation and then run the troubleshooter from there. If you've made some modifications to your hardware, you have to click the “I changed hardware on this device recently” option for further suggestions.

As you know, Windows 10 comes with the option to create Mobile Hotspot for other devices. This allows you to share your Ethernet connection. However, there are times when one of your devices might fail to reconnect to the mobile hotspot again. For instance, you moved out of the Wi-Fi range because you have somewhere to be and whatnot and when you’re back you find that you are now unable to reconnect to the Windows 10 Hotspot or the shared network. Although you can always restart the mobile hotspot to resolve the problem, however, it might only be a temporary fix. So in this post, you will be given options for a much better solution to the problem. This kind of problem seems unusual and does not occur that often. To fix it, you can try to set up DNS on your Windows 10 device and then configure the settings on the mobile device. It seems that what’s happening here is that the mobile device is unable to lock on to the Mobile Hotspot when the IP address changes for some reason.

Option 1 – Try changing the DNS settings on your laptop

In this option, you need to make sure that IPv4 and IPv6 are selected on your Ethernet connection. You also have to change the Preferred DNS server as well as the Alternate DNS server to 8.8.8.8 and 8.8.4.4, respectively. You also have to validate the settings before you exit just to ensure that you’ve entered everything correctly. After that, open Command Prompt and run the ipconfig command and then take note of the IP address, Gateway DNS 1 and DNS 2.

Option 2 – Try changing the Wi-Fi settings on your mobile device

This option should be mostly the same on all your mobile devices. And given that OEMs build their customization and skin, you might have to fiddle around a little to get the settings. Refer to the steps below to change the Wi-Fi settings:

• Go to the Settings of your mobile device and tap on Wi-Fi.
• Then click the Mobile Hotspot connection that you’ve created on your laptop.
• After that, input the password and tap the Advanced options.
• From there, tap on IP settings and select the Static option instead of DHCP.
• Now you have to enter the IP address, Gateway, DNS 1, and DNS 2 of the laptop you’ve taken note of earlier and that’s it.

Note: If you are already connected to the Mobile Hotspot, long press on the Wi-Fi network and select the Modify Network option and then follow the steps given above to change from DHCP to static. Once you’re done, your mobile device should now be able to connect to the Windows 10 Mobile Hotspot all the time.

Error Code 0x80072F8F - What is it?

Error Code 0x80072F8F manifests in one main way. It is known to appear as early as Windows 7, and mainly deals with an error that occurs in the update process, or when the computer is trying to connect to the online activation service. It can appear when the activation fails to verify the product key. The error code will present itself when the system realizes that the PC's date and time are incorrect. Error Code 0x80072F8F will also appear if the computer has determined that the time zone settings on the computer are not accurate.

When Windows is going through the installation process and is verifying all of the information associated with the computer, Error Code 0x80072F8F will arise, indicating that the information in the computer's settings is not valid. Correct times and dates are necessary when using serial validation keys to install Windows. When these settings are outside of the tolerated window, the problem will arise.

Error Causes

There is only one main symptom to look out for, and it will manifest during a Windows installation. In the midst of the installation, the computer will not be able to proceed with the installation if Error Code 0x80072F8F has popped up. Because the information cannot be verified, Windows will not be able to continue the installation process when the time settings are not accurate. This interrupts the process, causing the need to edit the settings, restart the computer, and try again. It is imperative to be sure that the date and time on the computer are inside of the tolerated window for the serial key.

• This error code will not give any information on how to correct it.
• Windows Error 0x80072F8F is displayed on the screen.
• The error code appears when typing the Windows serial key and proceeding.

Further Information and Manual Repair

When experiencing Error Code 0x80072F8F, the date and time need to be corrected in the computer settings menu, and then verify the correct time zone settings.  There are a few different ways to edit the time and date settings, and one may need to even edit the time zone settings. After this, restarting the computer may be needed. When booting into Windows, the validation code should be activated within 30 days of obtaining the serial number.

• Method One

Check the time and date settings.

1. Open the Start menu.
2. Select Settings, then Time and Language, then Date and Time.
3. Check and make sure that the PC is operating at the correct time and date.

• Method Two

Ensure that the computer is connected to the internet.

1. Enter “network troubleshooter” into the search box located on the taskbar.
2. Select “Identify and Repair Network Problems”.
3. Follow the instructions that are given on-screen. This will fix any problems that the network is experiencing.

• Method Three

Review the timezone.

1. Open the Start menu.
2. Select Settings, then Time and Language, then Date and Time.
3. Check to make sure that the correct timezone is selected from the drop-down menu.

• Method Four

Reboot the PC and check if that fixes the problem. This may help in the event that the network troubleshooter does not detect a problem.

After completing these steps to edit the time, date, and time zone settings, it may be necessary to restart the computer. This is to ensure that the computer will save and recognize the new settings. After restarting, continue the process as intended and enter the product key. The computer will now be able to verify the product key since the time and date will be recognizable. The Windows installation should proceed as normal and complete successfully when the time, date, and time zone are inside of the parameters for the Windows product key.

In short, if it is not, the computer will not be able to recognize the product key, thus will not be able to install the Windows product. Generally, the fix is quite simple and does not take much time at all, but it is very important.

USB storage devices are used to store small and even big files, depending on their sizes. Usually, the sizes of the USB vary from 2GB up to 16GB. And as time passes, they have advanced quite a bit and now it’s common to find USB sticks with a capacity of 32GB, 64GB, or even 128GB. And since they now have large capacities, USB storage devices are often used for storing backups of system data as well as creating an image. However, there are times when you might encounter an error message while trying to create a backup or image on your USB device. The error message states:

“The drive is not a valid backup location.”

One of the causes of this problem is that Windows was not able to recognize the USB drives as a valid backup location since USB storage devices weren’t previously large enough to store system images. To fix this error, here are some possible solutions that might help.

Option 1 – Try creating a sub-folder in the USB drive and backup all the images there

The first thing you can try to do is to create a sub-folder on your USB device. This is one good way you can bypass the USB drive limitation. How? Refer to the steps below.

• First, right-click on the USB storage device and select Format.
• Next, select NTFS as the File System and check the box next to Quick Format.
• After that, click on Start to initiate the formatting process.
• Once the formatting process is completed, open the USB drive and right-click anywhere inside its main drive window, and then select New > Folder.
• Then name the folder to be created as “Image (or anything you please)”.
• Afterward, right-click on the folder and select Properties.
• From there, go to the Sharing tab and click on Share.
• Now check if the Permission level on the System owner which should be your username is labeled as “Owner”.
• Then try to back up your files again using your USB drive while keeping the sub-folder as the backup location.

Option 2 – Update the USB Controller Drivers

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
• Restart your PC and then click the “Search automatically for updated driver software” option.

You also have the option to update the motherboard and the USB driver from the manufacturer’s official website.

Option 3 – 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.

A lot of Windows 10 users prefer the black theme on their computers and when you see anything but black it can get quite annoying. Such as is the case of the Taskbar which, as you know, is usually dark, however, when you take a look at the Cortana search bar, instead of seeing black, you’ll see that it has turned white. To fix this issue, read on as we will provide you some options you can try to set the Cortana search bar back to black. Before you proceed, take note that the options provided below will change all white search boxes to black and that one of these options needs administrative privileges.

Option 1 – Try changing the default App mode

As you know, Windows 10 has two modes, namely the Light and the Dark. Thus, you can switch to the Dark mode so that your Cortana search bar will be black as well. However, remember that it will completely change everything into dark mode so there will be no more Light mode elsewhere.

• First, you need to click on the Start button and then click on the cog icon to open the Windows 10 Settings.
• Next, from the Settings Menu, select Personalization and then select Colours from the left pane.
• Then scroll down until you see the “Choose your default app mode” option and select “Dark”.

After you apply the changes, it will change the Cortana search bar into black instantly. Aside from that, you will also see the User Interface changing into dark mode.

Option 2 – Try changing the Registry value

If you are well-versed in editing registry keys, then you need to try this option. But before you go over the steps below, make sure that you create a System Restore point first so that if anything goes wrong, you can always go back to how it was before the changes were applied.

• Tap the Win + R keys to open the Run prompt.
• Then in the field, type in “regedit” and hit Enter to open the Registry Editor. If a User Account Control prompt appears, just click Yes.
• Now that you’ve opened the Registry Editor, navigate to the following key:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionSearchFlightingWhiteSearchBox

• After that, double-click on the “Value” key located on the right pane and set the value to “0” instead of “1” and then click Ok to save the changes made. You should now see a black or grey text box color instead of white.

Option 3 – Try changing the Region

In some forums, a lot of users stated that changing the Region also worked out for them in changing the white Cortana search bar to white. Thus, you need to change the region settings of your computer temporarily. To do so, follow the steps below.

• Type in “Regional Settings” in the box and then click it as soon as it appears from the search results.
• Next, make sure to select a region where Cortana is not available.
• Then select apply to that region. After that, it will change the Cortana search bar color to black.
• Now sign out and sign back in and revert to the original settings. But the changes you made earlier in Cortana will still remain.

If VirtualBox suddenly displays a black screen without any text or mouse cursor when you are trying to boot a guest operating system, then read on as this post will guide you in fixing such an issue. This black screen occurs when Windows 10 failed to provide a specific setting that VirtualBox requires. Consequently, you will not be able to install or use any guest operating system in VirtualBox even if your PC has virtualization support, the best thing you can do now is to fix this black screen issue. There are two ways you can fix this black screen in VirtualBox, you can either try to disable Hyber-V or disable 3D Acceleration. For more details, refer to each one of the given options below.

Option 1 – Try to disable Hyper-V

Hyper-V is a built-in virtualization tool available in Windows that helps users in creating a virtual machine as well as install a guest operating system without using any third-party tool like VMware, VirtualBox, and many more. However, the problem with this virtualization tool is that some systems cannot run it and VirtualBox simultaneously which is most likely why the screen abruptly turns into black. Thus, you have to disable Hyper-V to resolve the problem. How? Refer to these steps:

• In the Start Search, type “Turn Windows features on or off” and then click on it from the results.
• Once you’ve opened the Windows Features window, remove the checkmark from the Hyper-V box.
• Click the OK button and then restart your computer.
• Now try to use VirtualBox again and see if the problem is fixed.

Option 2 – Try to disable 3D Acceleration

The guest operating system will use the host computer’s GPU to render 3D graphics if you enable the 3D Acceleration for the virtual machine. To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem. In fact, a lot of operating systems have failed to use the 3D Acceleration for the guest operating system because of this black screen issue. To disable it, follow these steps:

• Open VirtualBox on your computer and select the virtual machine.
• Next, click on the Settings button and go to the Display section.
• After that, look for a checkbox named “Enable 3D Acceleration” located on your right-hand side and then uncheck it.
• Save the changes you’ve made and reboot your PC and see if you can now run the virtual machine without any problem.
