The world today is still sadly under pandemic and by the looks of it, COVID-19 is here to stay, well at least for some time in the near future. Razer seems to think so as well since their upcoming gear is not really what you would expect. Enter Hazel, a new and upcoming Razer smart mask.

Protection

Hazel mask has a high bacterial surgical N95 filter with fluid resistance that will protect you against large droplets and splashes. A detachable active ventilator regulates airflow and is capable of filtering around 95% of airborne particles. Mask comes with a special charging case that has an auto sterilization UV light that will kill bacteria and viruses inside the case interior while it charges. When the mask is recharging it will change color from red to green visually showing the level of the current charge. Mask of course has easy to replace filters inside ventilators and Razer is standing by that fully charged mask will last enough for full-day use. An active ventilation system brings cool air while releasing breathing heat at the same time drastically reducing CO2 inside the mask that could produce dizziness and headache. Silicon guard is on its edge gluing to around your face in order to prevent exterior air sneaking inside the mask and positioning it firmly so it does not rest on your lips in order for easier and clearer communication.

Hazel personalization and technical features

Hazel has a clear and transparent design making it better for social interaction since other people will be able to see your lips and smiles thus making it more natural. A low light mode that turns on automatically when it is dark outside is also aimed for easier communication. Speaking of communication, the mask comes with voice Amp technology that has a built-in mic and amplifier thus making your voice lines clear so you are not muffled when wearing the mask itself. Your friends and other people will be able to hear you like you are not wearing a mask at all. Thicker air loops apply less pressure on ears and can be adjusted for a more secure fit, while the mask itself can be custom-made to fit your face shape. And of course Hazel comes with 16.8 million colors and a suite of effects with Razer Chroma RBG

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. To fix the ERR_CERT_COMMON_NAME_INVALID error, here are some suggestions that might help.

Option 1 – Check the website’s certificate

If you own the website where you’re getting the error, then you might have to check if the website’s certificate is installed properly and configured on the server as it could be the reason why you’re suddenly getting the error.

Option 2 – 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 you’re getting the ERR_CERT_COMMON_NAME_INVALID error. 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 3 – 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 ERR_CERT_COMMON_NAME_INVALID error in Chrome. 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 4 – Run the built-in Malware Scanner and Cleanup Tool in Chrome

In case you don’t know, there is actually a built-in malware scanner and cleanup tool in Chrome that helps you get rid of any unwanted ads, pop-ups, and even malware, as well as unusual startup pages, toolbars, and other things that could affect the performance of the browser. In addition, this built-in tool in Chrome might also help in fixing the ERR_CERT_COMMON_NAME_INVALID error.

Option 5 – Reset Chrome

Resetting Chrome can also help you get rid of the error. Resetting Chrome means 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.

The Disk Management tool in Windows 10 is a built-in tool that contains a user interface used to manage disk partitions to administrators of the computer. There are lots of instances when you have to change the size of the hard disk partition or reduce the size and so on. This is where the Disk Management tool comes in. It’s useful as the command line interface can be quite confusing and risky for some users. However, there are cases when this tool stops working. A proof of this the reports submitted recently by some Windows 10 users. Based on the reports, the Disk Management does not load or respond. If you are having the same problem, read on as this post will give you some suggestions on what you can do to resolve the problem.

Option 1 – Try restarting the Disk Management Service

• Tap the Win + R key combination to open the Run dialog box.
• Then type “services.msc” in the field and hit Enter or click OK to open the Windows Services Manager.
• Next, scroll down in the service list until you see the Virtual Disk Service. Double click on it to open and then select Automatic.
• Click on Apply and OK to save the changes made.
• If it hasn’t started yet, you can just click on the Start button to start the Service. The Virtual Disk service provides management services for disk, volumes, file systems as well as storage arrays.
• Now save all the changes you’ve made and restart your computer. Then check if you can now use the Disk Management tool without any problem.

Option 2 – Try using the System File Checker scan

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 some issues with the Disk Management tool. To run the SFC command, follow the steps given below.

• Boot your PC into Safe Mode.
• 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 3 – Try using the DISM tool

Aside from the System File Checker, the DISM tool can also help you resolve the issue with the Disk Management tool. It helps in restoring the health of your computer.

• Open the Command Prompt as admin.
• Then type in this command: Dism /Online /Cleanup-Image /RestoreHealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Try using Diskpart and Fsutil

If both the System File Checker and DISM tool didn’t work, you can use command-line tools like diskpart and fsutil. These command-line tools are powerful but you need to be careful especially if you’re not that familiar with using them. However, it’s recommended that you have somebody who knows if you’re really inexperienced with this kind of stuff.
