REevil is one of the most active and successful hacking groups connected to Russia and operating all over the world. The group recently demanded a huge bitcoin ransom for an attack targeting IT firm Kaseya in the USA. Since Tuesday blog and payment site run by REvil group cannot be longer reached without any kind of explanation or why. The reason behind the disappearance is unknown but has sparked speculation that the group may have been targeted deliberately by authorities. US President Joe Biden said he raised the issue with Vladimir Putin during a phone call on Friday, after discussing the subject during a summit with the Russian president in Geneva last month. Mr. Biden told reporters that he had "made it very clear to him...we expect them to act" on information and also hinted the US could take direct digital retaliation on servers used for intrusions. The timing of Tuesday's outage has sparked speculation that either the US or Russian officials may have taken action against REvil - though officials have so far declined to comment and cyber experts say sudden disappearances of groups are not necessarily uncommon. The development comes after a series of high-profile ransomware attacks which have hit major US businesses this year. The FBI accused REvil - also known as Sodinokibi - of being behind a ransomware attack on the world's largest meat processing company JBS last month.

If you encountered an error message saying, “We couldn’t find any drives, To get a storage driver, click Load driver” when you try to install Windows in a VirtualBox machine, then you’ve come to the right place as this post will guide you in fixing this error. This error message is displayed on the screen where you have to choose a partition to install the guest operating system. This error is most likely due to the lack of correct settings as well as a corrupted virtual disk. To fix this error, you have to remove existing storage devices, create a new storage device and select the correct ISO file.

For complete instructions, follow the given steps below.

Step_1: The first thing you have to do is remove all the existing Storage devices and since this option is already available in VirtualBox by default, there is no need for you to install any third-party software. Step_2: After that, open VirtualBox and select the virtual machine and then click the Settings button. Step_3: Next, switch to the Storage section and on your right-hand side, you will see “Controller: SATA” and two other sub-labels. From there, select Controller: SATA and then click on the red cross button that says, “Remove selected storage controller”. Step_4: Now click on the Add new storage controller icon and select the “Add SATA Controller” option from the given list. Step_5: Afterwards, click the “Add hard disk” button and select the “Create new disk” option, and then you have to create a new virtual disk for your virtual machine. Step_6: Verify if you have selected Dynamically allocated while you create the virtual hard disk. Once the process is completed, you will get a “.vdi” file in the list. Step_7: Next, click on the “Add optical drive” button and select the “Choose disk” option. Here, you have to select the ISO file and if you can find an ISO file in the given list, select it from there, else, you have to click the Add button and navigate to the folder where the ISO file is located. Step_8: Once you’re done, click the OK button and boot your virtual machine. You should see options instead of the “We couldn’t find any drives, To get a storage driver, click Load driver” error message. If you see the options, you can now create a new partition and start the installation process of the Windows operating system in the VirtualBox machine without any problem.

If you connected headphones to your Windows 10 computer to listen to audio but when you check it in the playback devices, you’re not able to find it, read on as this post will guide you in what you can do to figure out what exactly caused this kind of problem and how you can resolve it. This kind of issue could simply be with the headphone itself or the headphone port or your operating system. So if it turns out that the problem is with the hardware, you might have to replace the components. However, it is recommended that you troubleshoot the problem first before doing that. The most basic thing you can do is to try changing the headphone port, although this can be quite difficult since most computers don’t have any extra port for headphones if your computer has one, then give it a go. If it still didn’t work, follow each one of the options provided below.

Option 1 – Try to run the Playing Audio troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to update the Audio driver

If the error has something to do with software, chances are it might be related to the audio driver – it could be that the newest version of your Windows 10 does not work well with the old version of the driver. This is why you have to update your audio driver to the newest available version.

• Tap the Win + R keys to open the Run dialog box and then type in MSC and tap Enter or click OK to open the Device Manager.
• Expand the section of the Audio inputs and outputs.
• And then from the drop-down menu, select the Update Driver option and follow the on-screen instructions to install the latest version of the driver.
• Then also click on the option, “Search automatically for updated driver software.
• Restart your PC after the installation.

Note: If updating the Audio driver didn’t work, you can go to the website of your PC manufacturer and look for the support section where you can download the drivers for your computer. You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 3 – Try enabling the headphones from the playback devices

• Tap the Win + R keys to open the Run dialog box and type the “CPL” command.
• Tap Enter to open the Playback devices.
• Next, right-click on any open space section and check the boxes for the “Show Disconnected Devices” and “Show Disabled Devices” options.
• After that, this should help in displaying the headphones in the section of Playback devices.
• And if they are disabled, you can just right-click them to have them enabled.

There are times when you might notice that the Drive letter from the File Explorer is missing, right after you install an update in your Windows 10 computer. So if you are facing this issue right now, then you’ve come to the right place as this post will guide you on what to do to fix it. In case you don’t know, a drive letter represents a single alphabetic character which is through A-Z typically. This could be assigned to a physical disk partition, floppy disk drive or the removal device/ CD-ROM/ mapping network drive in your PC. In most cases, the drive letter “C:” is assigned to the first disk partition where the running Windows is installed. Thus, if the assigned letter is missing from either the Disk Management or the Windows File Explorer, it could result in inconveniences or will leave the partition inaccessible. To fix this problem, you can try to show the missing drive letters manually or make sure that the drive has a drive letter assigned in the Disk Management as well as assign the letter using a tweak in the Windows Registry. For more details, refer to the options provided below.

Option 1 – Try to show the missing drive letters manually

• Open the Folder Options from the Start Search and go to the View tab,
• Next, scroll down on the list of given options until you see the “Show drive letters” option and then check the box that’s marked against this option.
• After that, click on the Apply and OK buttons and then go back to the “This PC” window. You should now see the drive letters

Option 2 – Make sure that the drive has a drive letter assigned in Disk Management

As you know, every drive is assigned a drive letter in Disk Management. However, if it goes missing, you can still get it back through Disk Management. To do so, follow the steps below.

• Open Disk Management and from there, right-click on the menu of a partition or volume and you should see a function named “Change Drive Letter and Paths”.

Note: This function allows you to add the drive letter, remove the drive letter and change the drive letter. If the last option, namely, “Remove”, is selected and applied, the letter of the drive will be removed and won’t appear in Disk Management. Thus, this could be one of the reasons why a drive letter is missing.

• You need to click on “Add” to assign a letter to the selected drive in order to reverse the change. Note that you must assign the drive with the original letter because if not, the programs that rely on the original letter might not work as expected.
• If the original letter is already taken by a new drive, you need to change the letter of that new drive to another available letter.
• Then allocate the released letter of the targeted drive.

Option 3 – Try assigning the letter using a Registry tweak

The next thing you can do to fix the problem is to assign the letter using a tweak in the Windows Registry but before you do that, make sure that you create a System Restore point first, after that, follow these steps:

• Tap the Win + R keys to open Run and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMMountedDevices
• From there, check if a device is shown as being mounted at the specific drive letter and then right-click on that drive letter.
• Select the “Rename” option from the right-click menu to change the letter to any other available letter.
• Exit the Registry Editor and restart your computer.

Option 4 – Try to format the destination drive

Formatting the drive can also help you resolve the error. To format it, follow these steps:

• To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
• Next, right-click on the drive and select Format.
• After that, uncheck the “Quick Format” option and then format your drive properly.
• Now once the formatting process is finished, unplug the drive and plug it back in afterward.
• Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
• After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
• From there, right-click on the drive volume and select initialize disk.
• Next, select the correct partition type and proceed.

If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve this Activation error is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.
