As you know, a Virtual Private Network or VPN is used to access a particular network from another network which is why it is also referred to as a mini-internet. Moreover, you can use it in two ways. One, you can use it to get you access to a closed server which means that you would not be getting access to the internet. Second, you can also use it to access a set of resources while at the same time get access to the internet. However, what if you want to access your resources at home even when you’re away? And what if you want to use the private server at home or at your office even when you’re away? This is where the callout for a VPN server for yourself comes in. And so in this post, you will be guided in how you can create a public VPN server on your Windows 10 computer. Follow each one of the given steps below to get started. Step 1: Find your IP address. This step is rather simple since all you have to do is open Control Panel > Network and Internet > Network and Sharing Center. From there, click on “Local Area Connection” and then click on Details where you’ll see your IP address next to “Autoconfiguration IPv4 Address”. Step 2: Next, set up port forwarding on your router. In this step, you will have to configure port forwarding in your router so that you would be able to connect to the VPN server through a public network like the internet.

• Log in to the Admin Panel of your router. You have to do this since your router will be the gateway for your access to the network.
• After you’re logged in, look for the “Port Forwarding” or “Applications and Gaming” or “NAT/QoS” menu tab and other similar names.
• Now you need to set the port number to 1723 for connections based on Point to Point Tunneling Protocol.
• Then save the configuration and reboot your router.

Step 3: Set up a VPN server on Windows 10.

• In the Cortana search box, type “ncpa.cpl” and click on the related entry from the search results.
• After that, tap the Alt + F keys to bring down the File Menu and then select New Incoming Connection which will open a mini window where you can allow the user accounts on the particular machine to access the VPN connection.
• On the other hand, you can also click the “Add someone” button so that you can add someone else to the whitelist that can access the connection.
• Now click on Next and you’ll see an option to select how people will connect to the network. Check the checkbox for the “Through the Internet” option.
• After that, you will see a page where you have to configure the network. Just select IPv4 and then click on Properties.
• From there, you will be asked to continue some additional settings like letting users access your Local Area Network or how IP addresses will be allocated to these users. Click on OK to save the changes you’ve made.
• Click on Allow Access after you configure the network. And if you want to, you have the option to print this information for future reference or for the client machine.
• Now click on Close to exit the configuration process.

Step 4: Allow the VPN Connections through the firewall In this step, you will have to allow the VPN connections through the firewall.

• In the Cortana search box, type “Allow an app through Windows Firewall” and click on the related search result to open the intended Windows Firewall settings.
• Next, click on Change Settings.
• Then scroll down to check if Routing and Remote Access is Enabled for both the Public and Private networks and click on OK.

Step 5: Set up a VPN connection on Windows 10 Now all that’s left for you to do is to set up a VPN connection on Windows 10.

• Go to Settings > Network and Internet.
• From the list of options given, click on VPN located on the left pane to see the related settings.
• After that, click on the “+” icon to add a VPN connection.
• Next, select Windows Default under VPN Provider and under the Connection Name, input your VPN’s name, and then enter the IP address you got from the VPN service provider under the Server name or address section.
• Now select PPTP under VPN type since it is the most commonly used protocol for VPNs.

Corsair is well known for RAM memory modules for PC but then it has expanded to PC peripherals and even selling some pre-build computers as well in past few years. New Corsair expansion now includes a laptop line, starting with their new gaming laptop Voyager.

Voyager laptop is packed with a mechanical keyboard and MacBook-like touch bar for your typing and pointing needs. It is built with a 16-inch QHD+ screen packing 240Hz that is run by Radeon 6800M GPU. Also inside lurks AMD 16 thread Ryzen 9 6900HS CPU, Wi-Fi 6E support, Dolby Atmos audio, and full HD 1080p WEB camera.

The keyboard has low-profile mechanical Cherry MX switches with per-key RGB lightning and above is what Corsair calls a macro bar, with 10 shortcut buttons and a small LCD in the center.

Corsair is also including a few features that tie in with its other products. Many of the company’s keyboards, mice, and other accessories use the ‘Slipstream’ USB wireless adapter, which is built into the Voyager laptop. The macro bar is also configured using the same software used for the Elgato Stream Deck, a popular product sold by Corsair.

As you know, each one of the applications that you use in your Windows 10 computer has its own set of permissions by default. These applications either allows or denies the interactions between a few other applications, depending on their own needs. This is why you might suddenly encounter a message that says,

“This app wants to access your pictures” or “This app wants to access your account info”

both of which are followed by two buttons that will ask you to Allow or Deny the action. You can always click on any of the given options. This will determine the permission of the application. Users in Windows 10 are given the option to either allow or deny applications in accessing their account information like name, picture and other account information. Thus, in this post, you will be guided on how you can change the Privacy settings of these apps to allow or deny them permission to access not just your account info but for all users, as well as specific apps in Windows 10. The user account information is part of the Privacy data in Windows 10 that you can control easily using the Settings app. In fact, you can revoke or grant access permission for your account information, all the users and specific applications to do that, follow each one of the instructions provided below carefully.

Allow or deny apps permission to account info for yourself:

Step_1: The first thing you have to do is open Settings. From there, select Privacy. Step_2: After that, scroll and look for Account info and select it. Step_3: Now turn off the toggle button for the “Allow apps to access your account info” option if you want to deny apps permission to your account info. But if you want to allow them access, simply turn the toggle button on. Keep in mind that when you allow access or permission, you can select which apps can access your picture, name, and other account info by simply using the settings on the page you’re currently in.

Now if you want to allow or deny apps to access your account info for all the users, here’s what you have to do:

Step_1: First, open Settings and click on the icon for Privacy. Step_2: Next, scroll down until you see the Account info located on the left side and then click on it. Step_3: After that, click on the Change button under the “Allow access to account info on this device” section. If you want to deny account info access for all other users, then turn the toggle button off. Doing so will automatically disable not just the account info access for all users but also for all the apps as well.

On the other hand, if you want to allow or deny account info access to specific apps, you can do so by following these steps:

Step_1: As you did earlier, go to Settings and click on the Privacy icon. Step_2: After that, scroll down and select Account info located on the left side. Step_3: Now turn on or off the toggle button under the “Choose which apps can access your account info” section if you want to deny or allow specific apps permission to access Account Info. If you’ve turned on the toggle button under the “Allow apps to access your account info”, all the apps get access permissions by default.

There are times when it is really inevitable to delete your hard drive partitions especially if you are already running low on disk space in your Windows 10 computer. Users typically delete the volume which is not being used in such cases in order to free up some space for the volume that’s running low on disk space. To resolve the problem, users tend to use the Disk Management utility to delete hard drive partitions. However, some users reported that the “Delete volume” option is not available as it is grayed out. Thus, users aren’t able to delete hard drive partitions and aren’t able to free up disk space. This kind of problem usually occurs when there is a Page file on the volume that you are trying to delete and so on. Oftentimes, this issue is mistaken for the problem where you are unable to delete an EFI-protected partition. However, in this case, not only you are unable to delete EFI-protected partition but also NTFS file systems. This is really hard to deal with but worries not for there are some potential fixes you can check out to resolve this problem.

Option 1 – Try to manage the Page file in the Partition

As mentioned earlier, if a Page file exists in a partition, you won’t be able to delete it. The page file is what stores your data when the system’s random access memory fills up. To resolve this, follow these steps:

• Go to the Start menu and type “View advanced system settings” in the field and open it from the search results.
• Next, click on Settings in the Advanced tab.
• On the new window that pops up, go to the Advanced tab and select Change.
• Next, uncheck the checkbox of “Automatically manage paging file size for all drives” and highlight the drive you want to delete.
• Then select “No paging file” and click on Set.
• Now click on the Apply and OK buttons on all the windows and restart your computer.

Option 2 – Delete storage partition via Command Prompt

• Tap the Win + X keys or right-click on the Start button and select Command Prompt (Admin) or you could also type in “cmd” in the Cortana search box and right-click on the Command Prompt icon and then select the “Run as Administrator” option from the context menu.
• Once you have Command Prompt pulled up as admin, type in and enter this command – diskpart
• After entering this command, the Diskpart Utility will start. Diskpart Utility is a command-line-based utility just like Command Prompt but it will get a UAC Prompt after you invoke it so you have to click Yes for the UAC Prompt.
• After that, type in list volume and tap Enter to see the list of all the partitions created on your PC. This includes both types of partitions that are visible to the normal users in the File Explorer as well as the ones that are created by Windows 10 by default which helps it in storing the boot files and other essential system files.
• You should see a list of all the partitions made on your computer. Select the partition you want to delete by its Unique Identification number as Volume X where X denotes the Unique Identification Number.
• Next, type in the select volume number command and hit Enter to select the desired volume.
• Then delete the volume you’ve selected and type in the delete volume command and hit Enter to delete the volume you just selected and convert it into unallocated space.

Option 3 – Delete storage partition via Windows PowerShell

• Start by tapping the Win + X keys or simply right click on the Start button and select Windows PowerShell (Admin) or you could also type in “Windows PowerShell” in the Cortana search box and right-click on the Windows PowerShell icon and select the “Run as administrator” option.
• Once you’ve opened the Windows PowerShell, type in the Get-Volume command and hit Enter to get a list of all the partitions on your PC.
• Next, select the drive letter you want to delete and then type in the Remove-Partition –DriveLetter command and hit Enter to delete the selected partition. Note that you need to replace the drive letter with the letter of the partition you want to get rid of.
• After that, it will ask you for confirmation. Just hit the Y key for Yes or hit the A key to say Yes to All. This will delete all the partition you’ve selected and will move them in as unallocated space.
