Windows PowerShell is a powerful tool inside the Windows environment often overlooked by typical users which is a great mistake since it can offer a large array of functionality and usability and if used well can offer a unique working experience.
Today we will be using PowerShell to turn the WEB camera off so it can not be accessed, completely disabling it for use. You might want to do this for security reasons or just want to learn few new things. Whatever your reason might be, I am welcoming you to this tutorial and please do keep reading.
In order to disable the WEB camera first thing we need to do is to find a matching device ID. We will find this value inside the device manager, so press ⊞ WINDOWS + X to open the secret menu.
In the menu choose device manager and click on it.
When the device manager opens, expand the Imaging devices or Cameras section.
Right-click Integrated Camera or the primary webcam, and click Properties.
Go to the Details tab.
Under the Property section, click to select Matching device ID from the drop-down.
Right-click the value and select Copy
The next step is to download and install Windows Driver Kit (WDK)
Create and run a PowerShell script with the following parameters/values to disable the camera. Substitute the <FOLDER> placeholder with the actual name of the folder where your copy of Devcon is residing
$id = (Get-CimInstance Win32_PnPEntity | where caption -match '<PRIMARY CAMERA>').pnpDeviceID $ppid = "{0}{1}" -f '@',$id Set-Location c:\<FOLDER> Devcon status $ppid Devcon disable $ppid Devcon status $ppid
To enable the camera device, run the command below in PowerShell:
devcon enable $ppid
cd "folder location address"Step 5: After that, enter the following script to disable the security questions:
Update-AllUsersQAOnce you’ve completed the steps above, the Security Questions should be disabled and you will be notified with a message stating that the feature has been disabled. On the other hand, if you have a change of heart and you want to enable the Security Questions back, here are some steps you need to take: Step 1: First, open the PowerShell window as admin. Step 2: Next, run the same script with one more parameter such as:
Update-AllUsersQA -answer SecretAnswerStep 3: And that’s about it. Do not forget to replace the Secret Answer with your preferred one and once you’re done, it will be set as the answer for all the Security Questions. Step 4: Now all that’s left to do is go to the Settings app to change the answer to the questions and you should be good to go.
Virtual Reality or VR for short has come a long way from its infant stage and as 2022 is in half period we are looking at the VR market and reflecting on what has changed in one year. For starters, games have increased in quality and quantity while the hardware price has decreased making the whole VR experience a little closer to a wider audience.
Many companies have tried to get on the VR bandwagon but also many have failed. What remained are staples in VR hardware from large companies that have started with VR early and kept improving their headsets.
So with great pleasure, we are presenting the remaining best 3 virtual headsets so far of 2022 brought to you from Sony, Valve, and Meta.
If you want VR on consoles then there is really one option, and that is SONY VR. Premium Virtual Reality solution from SONY, sadly you can do this only on Playstation 4 and Playstation 5. Sony managed to pull off great quality hardware and packed with its exclusives on playstore at a very affordable price that is still cheaper than other products.
While waiting for the Sony PlayStation VR2 headset this one is still a great option and quality is still among the top of the game. From the time of its release until today, many AAA titles have been released for it as exclusives that you can not play any other way and some of them are really worth it.
Altho there are headsets like HTC Vive Cosmos Elite that have some features that place it as a better solution than Valve Index, Index is still an overall better VR headset as a whole product but its price is something that is keeping it still way out of reach of your standard user. The price, however, is really an illusion since it applies only when buying the system first time, you see Valve has created this headset as a modular design system making it upgradable meaning that you can, for example, buy newer controllers only and they will work perfectly with rest of hardware.
The modular design will save you money when you want to upgrade your VR system but as said entry price is steep. Besides its somewhat higher price than competitors, it is also notable that Index is a positional tracking VR set which means that it relies on a base station in order to locate the user. This means that once set, it is not so easy to change its location of use.
However, its quality and steam use are unmatched, high-quality games and compatibility that no other headset with steam will even pull off probably make Index one of the 3 best headsets out there. Half-life Alyx, arguably and currently one of the best VR games ever made so far was specifically designed for Valve Index and other games are behaving also incredibly nice with this headset, so if you want a great powerhouse for PC VR gaming, you will no go wrong in purchasing Valve Index.
Cheapest of the three and coming in various iterations, Meta has established itself from the beginning as a leading player in VR technology with its oculus line of products. Quest 2 is the next product in their line and it comes with 128GB and 256GB versions.
Meta has removed the need for the Facebook account for its VR systems and now you can use them without the need to send any kind of data to meta. Priced fairly for its entry 128 models this standalone VR set improves in any way possible from its previous iteration and sets the bar for what will come in VR's future.
Offering both wired and wi-fi connection with its standalone battery Quest 2 also is packed with a large library of games and it is user friendly as your typical game console but still allows some under-the-hood tinkering if you wish so.
Also, Meta's Vr solution since it uses inside-out tracking makes it incredibly easy to just pick it up and carry it with you wherever you go.
