In case you don’t know, Groove Music is due to retire its OneDrive streaming service this month. Despite that being the case, there is actually a workaround you can try to still continue enjoying music streaming. The app also allows you to play your own local files and if required, you can also modify or tailor the experience with new features – for instance, Groove Music brings an Equalizer to the settings of the app. As the name suggests, the equalizer allows you to tweak frequency responses to your liking. On top of being able to tweak individual bands, the equalizer supports few pre-set settings to enable quick changes. This post will guide you on the process of accessing and using the equalizer in the Groove Music app. To get started, refer to the instructions provided below. Step 1: You need to make sure that you are running the latest version of the Groove Music app or version 10.18011.1211.0 or higher in order to use the equalizer in Groove Music. If needed, you can check the version number from Windows Store. Step 2: Open Windows Store and then click on the ellipses icon and select the Downloads and Updates option. Step 3: Next, search for Groove Music and check its version number. Step 4: Now that you’ve verified the version number of Groove Music, you need to open the equalizer setting. It is enabled by default and to access it, click on the gear icon for Settings and select equalizer under the Playback settings. Step 5: After that, the Equalizer window will pop up. It is where you can configure the equalizer settings using the drop-down menu. Here are the following presets you can choose from:

• Flat
• Treble Boost
• Bass Boost
• Headphones
• Laptop
• Portable speakers
• Home Stereo
• TV
• Car
• Custom

Step 6: Drag the dots upwards or downwards to set your own preferences, as needed. Note: The only downside to this setting is that there is no shortcut available for quick access as you have to navigate through the Settings section manually to access it and change the preset configurations. In addition, the Groove Music app also works on the mobile version of Windows 10.

We are all waiting for the release of Intel’s Alder Lake series of processors and real-world results on its performance. Sadly lately it came to our attention that some games might have issues with the processor. Now before you go on the bandwagon on bashing Intel itself take note that it is not Intel’s fault at all. The issue that arises is mostly due to DRM software and how it works. As you might know or not, Alder Lake has two sets of cores, standard performance cores, and power cores, and with Intel’s Thread Director on-chip right cores will be used for the right tasks, and here lies the issue. DRM software might detect Thread Director as something suspicious and malicious, and then cut access to the game because of this. Intel, of course, has reached DRM manufacturers and places documentation about how software should be developed with this hybrid technology in mind. Of course, newer games will be updated if needed and everything will work fine, also games on GOG will work fine because of GOG’s policy of no DRM store but some older ones might be left in limbo. They could work fine but DRM might be triggered and prevent them from loading, usually, game developer itself removes DRM protection after some time but that is not really always the case and there is a chance that some games might simply just not work on Alder Lake CPU only because of DRM protection.

Conclusion

I will admit that I have not been a great fan of DRM in general, I understand that game developer want to protect themselves from piracy but how it looks they were not really successful with it. Even today single-player games get pirated on the day they are released and legally bought ones always make trouble for people that actually paid for them. I remember times when DRM was awful and you could install a game a limited number of times, luckily this was removed but it seems that many old habits still remain sadly and DRM is present even today in various forms. GOG is proof that people will buy DRM-free games and that they will support this kind of model. Maybe it is time to forget about fighting against piracy, you will not make it go away and people who do not want to buy games will not buy them, on other hand many users that do buy games, if they cannot use them they will rest to pirated version since that one will work. It is sad to see that pirated software can work better than a legal one and offer a more pleasant experience.

The Photos app in Windows 10 is the default photo viewer. However, there are times when it might encounter some problems while you use it. One of these problems in the Photos app reported recently is where users try to export or share the images and videos from the app but weren’t successful in doing so. This can be really quite a hassle in opening images on your computer, especially since the Photos app is the default photo viewer in Windows 10 and if you don’t have any other photo viewer app installed. This kind of problem in the Photos app can be noticed when you try to use the “Remix” function for both photos and videos. In other words, this problem can occur with just pictures, videos, as well as a combination of both. So if you are trying to watch a video using this app, then you wouldn’t be able to play it. In such a case, the only thing you can hear is the audio but you wouldn’t see anything except for a hazy purple screen that has not export or share option. There are several possible causes for this problem and it could be fixed by updating the display driver/graphics driver or disabling the hardware-accelerated video encoding. You could also try updating or resetting or reinstalling the Photos app. For more details, follow each one of the suggestions provided below.

Option 1 – Try to update the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the blank dialog boxes problem or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 2 – Try disabling the hardware-accelerated video encoding

The next thing you can do to fix the problem is to disable the hardware-accelerated video encoding in your computer. To do that, follow these steps:

• Open the Photos app and click on the visible three dots located in the upper right corner of the app and then select Settings.
• From there, you should see the version number of the app in the “About this app” section. So if your app is version 2018.18071.****0.0 or greater, you should see the Video section which has a toggle button.
• Turn that toggle button off to disable hardware-accelerated video encoding in the Photos app. This should fix the problem, if not, simply follow the next given options below.

Option 3 – Try to update the Microsoft Photos app

• Open the Microsoft Store and click on the three horizontal dots for the menu located on the top right portion of the window to see the options.
• Next, select Downloads and updates and then click the Get updates button in the top right. This will install any pending updates for all the apps including the Microsoft Photos app using the Microsoft Store.

Option 4 – Try resetting the Photos app

• To get started in resetting the Photos app, open the Windows 10 Settings.
• Then go to Apps > Apps & features.
• After that, scroll down until you see the Photos app option – click on it and open its Advanced options.
• From there, you will see the Reset button, click on it and click and then click on it once more to confirm.

Note: The process may take a couple of minutes to complete. Once it’s done, open the pictures again using the Photos app.

Option 5 – Try reinstalling the Photos app

If none of the options given above worked, then you might want to consider reinstalling the Photos app. Unlike what most users think, it isn’t really that hard reinstalling preinstalled apps as you have the Windows PowerShell for that. To use this program in reinstalling the Photos app, follow these steps:

• Open the Windows PowerShell program with admin privileges and key in the following command:

Set-ExecutionPolicy Unrestricted

• After that, execute this second command to re-register and reinstall the Microsoft Photos app.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

Note: In the command given, do not forget to replace the “PackageFullName” with the actual package name for the Photos app. After executing the command, it will uninstall the Photos app from your computer so you need to install it again from the Windows Store by simply looking for it. Once you found it, just click on install to start the installation process.

Many Windows 10 users often change the IP addresses of their computers’ network adapter in order to connect to the internet or network they belong to in times when there is no automatic connection for their computers. In most cases, access to modifying this setting is restricted for some odd reason even if you are an administrator. So if you are one of the users whose Windows 10 VPN IPv4 Properties are not working, this post can help you remedy that so that you can open and edit the IPv4 Properties on your Windows 10 PC. The common way to change IP settings is by going to Settings > Network and then to Internet > Change adapter options > Select Network adapter > right click and open Properties. From there, you can select TCP/IP 4 and modify it. If you aren’t able to do this, refer to the instructions laid out below to troubleshoot the problem in accessing the IPv4 Properties.

Option 1 – Try using PowerShell to manually set the IPv4 properties

As you are not able to set it using the interface, you can do so using PowerShell instead. Note that this option will only work for you if you run PowerShell with administrator privileges. After opening PowerShell, according to many users, you have to run the this command – set-DnsClientServerAddress -InterfaceAlias “Ethernet” -ServerAddresses xxx.xx.xxx.xxx,x.x.x.x,xxx.xx.xxx.xxx,x.x.x.x Usually, Ethernet is the name of your network adapter which is set by default. If you want to see the actual name of your network adapter, you can just type this command and tap Enter after doing so – Get-NetAdapter -physical | where status -eq 'up' After entering the given command, you will see a list of active Ethernet adapter in your computer as you can see on the image above. Note that the 4 sets of X like the one on the image below should match with the sequence:

Option 2 – Try editing the rasphone.pbk files

The rasphone.pbk files stores property for the connections and since you are not able to access the IPv4 properties, it is most likely that it has been disabled here. The good thing is that you can open these files and edit them using Notepad. Refer to the steps below to do so.

• Open the Windows Explorer and then enable the show hidden files option.
• After that, look for the files at this location – C:Users <username>AppDataRoamingMicrosoftNetworkConnectionsPbk_hiddenPbkrasphone.pbk
• Then right-click on it and select the “Open with” option and choose the Notepad app.
• After opening the file, look for “IpPrioritizeRemote” from the long list.
• Once you found it, set its value from “1” to “0”.
• After that, look for “IPInterfaceMetric” and set its value to “1” and tap Ctrl + S to save the changes you’ve made, and then exit and try accessing the IPv4 properties again. It should work, but if you’re still unable to access it, try the next option below.

Option 3 – Enable the Split Tunneling if you use VPN

All data goes back and forth when you are using a VPN service on your computer. And since you are using VPN, it could be that it disables the IPv4 interface. If that’s the case, you need to stay connected with both the local network and VPN and to do so, you have to enable Split Tunneling. How? Follow these steps:

• Open PowerShell with administrator privileges.
• Next, type in “Get-VpnConnection” and tap Enter. After doing so, it will give you the exact name of your VPN.
• After that, type in “Set-VpnConnection -Name “yourVPNName” -SplitTunneling $True” and tap Enter. Once you enter the command, it will free your IPv5 settings so that you can change it to connect with your local network if you prefer it to.
