If you have been using Windows for quite some time now then you’re probably aware of the BIOS or UEFI password. This password lock is the one that ensures you enter the set password even before your Windows PC boots up. However, there’s just one downside with the BIOS or UEFI password – there is no recovery option, unlike your Microsoft account. Worry not though for this post will guide you on how you can set or recover a BIOS or UEFI password on your Windows computer. The BIOS or UEFI passwords are stored at the hardware level which means that unless the OEM wants or has configured a way to recover the password, it is pretty much impossible to reset it. There are times when they are so strict that the only way to get through it by contacting customer care. Note that any Windows computer with this lock can’t be unlocked by trying to reinstall Windows. In this post, you’re going to have to remove the CMOS battery temporarily, clear unknown BIOS/UEFI passwords using the bios-PW website as well as call customer care. For more details, refer to the options provided below.

Option 1 – Remove the CMOS battery temporarily

In case you didn’t know, every motherboard comes with a CMOS battery which helps the computer system to keep the clock ticking and in making sure that the BIOS settings are not lost when the computer is powered down. Every time a computer is turned on, the CMOS battery ensures that the information is available for the computer to boot up. So when you remove the CMOS battery temporarily, say about 30 seconds or a minute, the settings will be lost. There are some motherboards that are built-in ways that when you remove the battery for long, it will reset everything including the password for the BIOS or UEFI.

Option 2 – Clear the unknown BIOS or UEFI passwords using a bios-PW website

If the first option didn’t work, you can try using this BIOS Password website at http://bios-pw.org/ to clear the password.

• When prompted by the BIOS, enter the wrong password a couple of times as doing so will lock you out of the system.
• After that, you will see a new number or code on the screen which will include a message about System Disabled [XXXXX] Service TAG [YYYYY].
• Next, open the BIOS Password website and enter the XXXXX code in it and make sure to tap the Shift + Enter keys or just enter.
• Now it will open multiple unlock keys which you can use to clear out the BIOS or UEFI lock on your Windows PC.

Option 3 – Call the customer care

If the second option still didn’t work, you have to call customer care and follow their suggestions for they will walk you through fixing the problem using the service tag or might suggest that you visit a service center to make things easier for you. Note: You also have the option to set a BIOS or UEFI password. Although it isn’t recommended, you still can do it if you really want to. Remember that the BIOS or UEFI interface varies from OEM to OEM so you must find something related to either PASSWORD or SECURITY. You will have the following similar options:

• Supervisor password – it’s the same as the master password that can change important system settings.
• User password – with this password, any user can change minor settings.
• Master password – you can use this password for a hard drive or as a general password.

There are several OEMs that offer micro-control where you have to enter the BIOS password. For instance, you’ll have the option to skip for a normal restart, or when you select a boot device while you might have to enter the password for unattended reboots or when your PC is powered on, etc. And if you are here to remove the password, you need to find a remove password option in the same section. You will be prompted to enter the set password once and if it’s correct, it will remove the BIOS password. After that, you have to save and exit the BIOS then restart your computer and check if the settings are properly applied.

Recently, a number of users reported that they were not able to run PLEX and other similar streaming services ever since a Windows Update was automatically installed in the system. The error in these streaming services has something to do with a missing Mfplat.dll DLL file from the Windows Media Feature Pack. On the other hand, some users also reported that the mfplat.dll error occurred on several games as well which used the Media Feature Pack. Usually, the mfplat.dll error is caused by the missing Media Feature Pack in Windows 10. Although most of the time the Media Feature Pack is installed by the application that needs it or through Windows Update automatically, there are just certain installers that do not have it. It could be that the Media Playback service was disabled by a particular Windows Update. Aside from that, the error might be because your computer is using Windows 10 N – a Windows 10 version that does not include the Media Feature Pack by default. Whatever the cause may be, you can troubleshoot the problem with the help of the options given below. But before you go on, keep in mind that downloading the missing DLL file and copying it to the folder of the program where you encounter the error won’t really help and will only make things even more complicated.

Option 1 – Install the Media Feature Pack for Windows 10 N version

As mentioned, the Windows 10 N version does not come with Windows Media Player. Meaning to say, the Media Feature Pack is also not installed by default or won’t be updated by the Windows Update component. So if you are not quite sure what Windows 10 version you currently have installed, refer to these steps:

• Tap the Windows key + S and then type “about” in the search box.
• From the search results, click on the “About your PC” to open the About tab of the Settings app.
• Afterward, scroll down to the Windows specifications and check your Windows version under Edition.

Note: If you’ve determined that your computer is using the Windows 10 N version, you need to install the appropriate Media Feature Pack for your computer. How? Refer to the steps below:

• Click this link to download and install the Media Feature Pack from Microsoft’s official website.
• Upon installation, select the edition you want to install using the drop-down menu and then click on Confirm. Take note that there are few reasons why you’d want to install the older version since most streaming services like PLEX and most games usually require version 1803.
• After that, wait until the request is validated. The download should begin in a few minutes automatically.
• Once the download is completed, open the installation executable file and follow the next on-screen instructions to install the Media Feature Pack on your computer.
• Restart your computer. After your computer has rebooted, open the application where you’re getting the mfplat.dll missing error and then check if the problem is now fixed.

Option 2 – Enable Media Playback via Command Prompt

If you encounter the mfplat.dll missing error when you attempt to run PLEX or other similar streaming service and you’ve already verified that the Media Feature Pack is indeed installed, you might want to try enabling it using an elevated Command Prompt. There are cases when a particular Windows Update ends up disabling the feature and creates the grounds which results in the mfplat.dll missing error. Thus, you can have to enable the feature via Command Prompt.

• Tap the Win + R keys to open the Run dialog box.
• Then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• Next, click on Yes if a User Account Control prompt pops up.
• After opening Command Prompt, copy and paste the following command and hit Enter to execute it:

dism /online /enable-feature /featurename:MediaPlayback

• Close Command Prompt and then open the app once again to check if the problem is now fixed.

Option 3 – Try extracting a copy of the mfplat.dll file from the windows.old directory

If you encounter the error shortly after you just upgraded to Windows 10 from an older version, the best thing you can do to resolve the problem is to use windows.old directory to fetch an old copy of the mfplat.dll file. To do so, follow the steps below.

• Go to the Windows drive and then look for the windows.old directory where it preserves a copy of your old operating system as well as associated files in case something goes out of hand during the upgrade process.
• After that, open the windows.old folder and then go to the syswow64 folder.
• Next, from the syswow64 folder, copy the mfplat.dll file and paste it to C: windows syswow64.
• Restart your computer and check if the error is now resolved or not.

Dune, arguably one of the best science fiction novels ever written was brought to a big screen first time by David Linch. Sadly movie itself went through development hell and a lot of troubles and the end result was somewhat strange. The audience was divided on it, some hated it, some loved it but for sure it left a mark in cinema history. Years have passed and just when people forgot about ever receiving another try on a book adaptation Denis Villeneuve has brought his vision of Frank Herbert's novel into its full glory on a big screen. The interesting thing about this new Dune movie was that from the start Denis envisioned it as a two-movie part openly saying that book itself is too complex to be done in a single movie. But, the issue arises when information about Dune part two was hanging on a thread on how well Dune part one will be received and performed in the box office. This naturally brought all kinds of speculation and worry among fans of the franchise, especially because the movie itself was really good and well made. Well for all of you fans and people who wanted to see a continuation of the story can rest at peace now since the Legendary picture has officially announced and green-lighted Dune part two. The budget was given and we can expect part two at the beginning of 2023.

The Windows Subsystem for Linus, also known as WSL, is a useful and excellent tool for developers. However, it isn’t without flaws as users can still encounter some errors when using it. One of these errors is the error code WslRegisterDistribution, 0x8007019e,0x8000000d. Although it seems like the error is have something to do with the installation of WSL, it could be a false positive since some users who’ve installed WSL still encountered the same problem. Here’s the context of the error:

“Installing, this may take a few minutes… WslRegisterDistribution failed with error: 0x8007019e/0x8000000d Error: 0x8007019e/0x8000000d The parameter is incorrect. Press any key to continue.”

Error code 0x8007019e or 0x8000000d could be due to the absence of supporting Windows 10 features since the error does not even let one use the WSL-based command line. If you are one of the users facing this problem, then you’ve come to the right place as this post will provide you with a couple of suggestions to fix it. There are two options you can check out to fix the problem, but before you do that, you need to make sure that the Windows Subsystem for Linux feature is enabled. The two options include enabling WSL using the “Turn Windows features on or off” option and using the Windows PowerShell.

Option 1 – Try to enable the WSL using the “Turn Windows features on or off” option

• To get started, search for “Turn Windows Features on or off” in the Start Search and click on the appropriate result to open a dialog box.
• After that, you will see a populated list in the dialog box and from there, look for the “Windows Subsystem for Linux” option.
• Once you find it, select OK. This will search and install the system files needed and ask you to restart your computer.
• Restart your computer. The Linux distro should now work without any trouble.

Option 2 – Try to use Windows PowerShell

The next thing you can do to fix the error code 0x8007019e or 0x8000000d is to use Windows PowerShell.

• Tap the Win + X keys and click on the “Windows PowerShell (Admin)” option to open Windows PowerShell as admin.
• After that, execute this command to enable the Windows Subsystem for Linux feature: Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

OEM Partition, also known as System Reserved Partition, is placed by the OEM to help users recover their computers or bring back the original state of the computer when it was bought. If you’ve observed that a part of your hard drive says “Healthy (OEM partition)” in the Disk Management and it occupies space in GBs, then this means that it’s normal and there’s nothing to worry about except that part of the storage space is not available and even when you right-click on it, the only thing it displays is the Help menu. Thus, in this guide, you will be guided on how you can merge as well as delete an OEM partition in your Windows 10 computer. Since the Disk Management tool in Windows won’t let you merge or delete the OEM partition, you can just use the built-in command-line tool known as Diskpart. Note that you have to be extra careful when you run the commands as it could mess your computer up and before you proceed with the instructions provided below, make sure that you create a System Restore point first. Once you have that covered, follow the instructions below. Step 1: Tap the Win + R keys to open the Run dialog box and type “cmd” in the field and tap Enter to open the Command Prompt. Step 2: Next, execute this command to launch the Diskpart tool: diskpart Step 3: Execute this second command to view the list of the disks in your computer: list disk Step 4: Now select the disk you want to manage by executing this command: select disk x Note: In the command above, replace “x” with the letter of your disk. Step 5: After that, execute this command to display all the volumes or partitions: list partition Step 6: Now execute this command to select the partition you want to delete: select partition x Note: You have to replace “x” with the partition you want to delete. Step 7: Once done, execute this command to delete the selected partition: delete partition override Step 8: Afterwards, execute this command to merge the OEM partition with the adjoining value: Extend Note: if you only want to merge part of the partition, you need to use this command “extend [size=<size>]”. For instance, you want to extend its size by 5GB, then you need to type “Extend size=5000”. The size you set is the size you select from the OEM partition. This will extend the selected volume by size in MB or megabytes.
