Installing a Windows 10 upgrade is definitely not an easy task since the process is not always smooth sailing and you could encounter some errors when doing so. This isn’t unusual since there are various software configurations and hardware configurations as well as services it depends on in order to properly work. So if any of them malfunctions or becomes corrupted, it will affect the process which will result in errors like the error code 0x80300002. When you encounter this kind of Windows Update error, you will see the following error message on your screen:

“We couldn’t install Windows in the location you choose. Please check your media drive. Here’s more info about what happened: 0x80300002”

You can encounter this kind of error if there is corruption in the partition table of the drive where the installation is in progress. In addition, corruption on the Media device could also cause this problem. So if you encounter this error when running Windows Setup, read on as this post will guide you in fixing it. There are several ways to resolve this issue. The first thing you can do is to verify the compatibility between the BIOS and the installation media. You could also try recreating all the partitions as well as recreating the bootable USB drive. For more detailed information, follow the given options below.

Option 1 – Check if the BIOS is compatible with the installation media

The first thing you can do to fix the error is to check if there are any compatibility issues between the BIOS and the installation media you’re using. This is actually one of the most likely reasons why you’re getting the error since this is a complicated point for the Windows installation process. If the installation media is based on GPT, then your BIOS must be based on UEFI. So if you have your bootable media with the MBR partitioning, you need to set your BIOS to Legacy.

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the “Legacy” option. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to Legacy and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Try recreating a new bootable drive

• Insert your USB drive into your PC.
• Tap the Win + R keys to open the Run dialog box and type in “cmd” and tap Enter to open the Command Prompt. Alternatively, you can also search for “cmd” in the Cortana search box to open Command Prompt.
• Once you’ve opened CMD, type in this command to open the DISPART utility – diskpart
• After that, you should see a new black and white window that would say, “DISKPART>”.
• Next, type in “list disk” in the command line and tap Enter to see the list of all the Storage devices as well as your hard disk connected to your PC. Here, you have to identify your disk’s number.
• Type in this command where “X” is the disk number you have identified and then tap Enter – disk X
• Type in this command and hit Enter to clear the table records and all the visible data on the drive – clean
• Now you have to recreate a new primary partition of the drive so you’ll have to type in this command and tap Enter right after – create part pri
• A new primary partition has been created so you have to select it by typing this command and tapping Enter – select part 1
• Now you have to format it to make it visible to normal users by typing – format fs=ntfs quick

Note: If your platform supports the Unified Extensible Firmware Interface or UEFI, replace the “NTFS” with “FAT32” in the command on Step 10.

• After that, type in this command and tap Enter after – active
• Finally, type this command and hit Enter to exit the utility – exit
• After you prepare the image for the operating system, save it to the root of your USB Storage device.

Option 3 – Try to recreate all the partitions

If none of the first two options given above worked, then you can try to recreate all the partitions instead. All you have to do is restart the Windows installation process and wait until you get to the part that says, “Where do you want to install Windows?”. From there, you will see options like delete, format, extend, create new partitions, and many more. Now you have to select the Delete all the partitions options and then use the “New” button to create new partitions. Just make sure that you have one primary partition at least where you can install Windows 10. After that, continue the installation of Windows on the new partition. Keep in mind that when you create a new partition, it also recreates the partition table configuration which means that the chances of getting an error are very unlikely.

DOTA2 involves teams of five players each, where each player chooses a “hero” character. Each game has two teams pitted against each other, on opposite sides of a map. Once you start, you and your teammates try to level up by fighting and defeating heroes from other teams as well as non-player characters who exist within the game universe. Once you have a strong enough team, you would then try to attack an opposing team’s base. If you destroy their “ancient,” your team wins. The teamwork and interactivity required to play the game are some of its biggest attractions. You can text and voice chat as part of the Dota 2 gameplay, enabling you and your team to come up with strategies to take over your opponents’ base and fortifications. For this reason, a properly working microphone and headset are important if you are to get the most out of this exciting online game. However, there are many times when you find that there are audio dropouts when you try to speak into your microphone. The question “How do I get my mic to work on Dota 2?” is one of the most commonly asked on gaming forums related to this game. Here are solutions for why this can happen:

1. You are logged in to another computer that is running the STEAM client

   While entirely rare, there are cases where the microphone in Steam is disabled because the same account is active and in use on a different computer. It may not notify you that your account is in use elsewhere. If this is the error, try to log out on other devices and then test it on only one system. If you cannot access the other computer that has access to your account, then change your password. This will automatically disconnect your Steam account from the other computer and let you enjoy voice chat in Dota 2 and other Steam games.

2. Your microphone is not properly set up in Dota 2

   From the main Dota 2 menu, before you start a match, you can set up your microphone for voice chat. At the top, left-hand corner, click the gear icon to open Settings Select the AUDIO tab and ensure that the Sound Device and Speaker Configuration are set to default. On the same tab, activate Voice (Party) and set your Push to Talk shortcut key for your team. Select the appropriate Open Mic Threshold using the slider at the bottom of this tab to get your microphone recorded at a comfortable level.

3. The Windows Audio Enhancements setting is turned on

   If you still cannot get your microphone to work properly, then your problem could be Windows Audio Enhancement. It is possible to get your microphone to work with Dota 2 by disabling these features. Right-click your volume icon on the system tray and select Recording Devices. Choose your active microphone then click its Properties button. On the Microphone Enhancements tab, make sure the checkboxes marked Voice enhancements and Acoustic Echo cancellation is unchecked Reboot your PC and retry using your microphone to chat.

4. Your audio drivers need to be updated

   If you try all of the steps above and still have Dota 2 not recognizing your mic input update mic drivers by going in device manager and choosing update driver.

In case you don’t know, Microsoft has included an Enhanced Search Mode in the new Windows 10 v1903. This new Enhanced Search mode, compared to the Classic Mode, indexes everything on your Windows 10 computer, and in this post you will be guided on how you can disable this new feature as well as discuss how it is different from the Classic Search mode. Over the years, the Windows 10 Start Search has changed. When you tap the Start button and when you type, the results that appear are categorized into Apps, Documents, Email, Web, Folders, Music, People, Photos, Settings, Videos, and many more. This is the reason why the Enhanced Mode was brought into the picture. So unless everything is indexed, this new feature wouldn’t be of much use. A Classic Search is the term used for the old search technique in Windows 10. The Classic Search mode is restricted to Libraries and Desktop and end-users can only select to customize the search location by adding them manually to the indexer. To simply put it, it would only index files and folders which you want to get indexed and if the search term is not in the index, it would initiate the regular search which would take quite a while and this is where the Enhanced Windows Search comes in. It indexes everything as it is its default nature which is the exact opposite of the Classic Search mode. This feature allows you to exclude folders where the Search will not look and index anything that could be personal to you. In addition, it can also impact the life of the battery of laptops, if you are using one. The initial crawl of your data will take place only when connected to power and during that time, both the CPU usage and battery will take a bit of a hit.

To enable the Enhanced Search Mode in your Windows 10 computer, here’s what you have to do:

Step 1: Go to Settings > Search > Searching Windows. Step 2: Next, click on the radio button for Enhanced. Step 3: After that, select the folders which the Windows Indexer should exclude from the Enhanced Search mode. And that’s about it. The next time you search anything on your computer, Windows will be looking at all the locations except for the ones you excluded and the results will be a lot faster compared to the Classic Search. Now that you’ve enabled the Enhanced Search mode, there are two settings you need to check out.

• Advanced Search Indexer Settings – this setting allows you to configure how or where Windows will search or what file types it will search in your computer. It will also open the same setting that’s available in the Classic Search.
• Run the Indexing Troubleshooter – when you click on the Indexing Troubleshooter, it will start to troubleshoot any Search and Indexing issues on your Windows 10 computer and fix them automatically.

The speed at which the CPU runs varies depending on any Windows laptop or desktop. And in case you don’t know, the CPU does not run at full speed all the time as it depends on how the operating system distributes the load so it works accordingly. However, there are instances when it runs at full speed especially if your Windows 10 computer is on a heavy workload. But if you find that even when your computer is already on a heavy workload and the CPU is still not running at full speed, then you need to look into this situation. To verify that your CPU’s speed, you can use any CPU stress test tool. This kind of issue is common on laptops compared to desktop computers since laptop runs on battery. The Intel Processor on laptops uses the Speed Stepping Technology which means that when you are doing some small tasks on your laptop, the processor’s speed is reduced. On the other hand, if this happens when you are using a heavy application, it can be due to a low charge on the laptop’s battery. Thus, Windows will try its best to keep the computer running for as long as possible by reducing the CPU speed or processor. But there are times when you are ready to sacrifice battery to make sure that the work gets done on time. To achieve that, here are some options you can check out.

Option 1 – Try setting the processor state to the maximum in Power Options

• Type “control” in the search box to view the classic Control Panel as well as the popular options.
• Next, click on Power Options > Change plan settings > Change advanced power settings.
• Then navigate to Processor power management > Maximum processor state.
• Now select 100% when it is on Battery and Plugged in.
• After that, expand the System cooling policy option and make sure to set it as Active to make sure that the battery won’t overheat.
• Finally, apply the changes made to all the profiles of the power management and restart your computer. This will ensure that your CPU will run at maximum power at all times.

Option 2 – Try to update or disable the Intel Power Management driver

The next option you can try is to update or disable the Intel Power Management driver. The Intel-powered computers have dedicated software that controls CPU speed and Fan speed when it needs to save battery. You can try disabling it temporarily and check if there are any changes with the CPU fan speed.

• First, restart your computer by holding the Shift key to boot your computer into Troubleshooting or Advanced mode.
• Next, go to Troubleshoot > Advanced Options > Command Prompt.
• Then change the directory to C:/Windows/System32/driver and then rename the file named “Intelppm” by entering the “ren intelppm.sys intelppm.sys.bak”.
• Now restart your computer.

Note: If you were not able to find the drivers in C:/Windows/System32/driver, check if they are available under C:/Drivers/IntelPPM. After that, the CPU speed should change now with the Intel driver missing from the system. And in case you want to enable it, simply follow the same steps given above and rename the file again.

Option 3 – Try disabling the IPPM using the Command Line or Registry Editor

• Command Prompt:
  • Tap the Win + R keys to open the Run dialog box and type “cmd” and tap Enter to open Command Prompt.
  • Next, type this command and hit Enter: sc config intelppm start= disabled
  • The “sc config” command you entered modifies the value of a service’s entries in the registry as well as in the Service Control Manager database.
• Registry Editor:
  • Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
  • Next, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesintelppm.
  • From there, double click on the intelppm and change the Start key value to
  • Now close the Registry Editor and reboot your computer.

Note: The steps given will make sure that the CPU will run at maximum power at all times.

One of the primary packages that install the Windows Media Player is the Media Feature Pack among other related files that are needed by the associated software products. And one of the essential DLL files in that package is the mfplat.dll file which is needed by various games and streaming services. So if this DLL file goes missing, you will most likely encounter any of the following error messages:

• “mfplat.dll missing”
• “The application failed to start because mfplat.dll was not found.”
• “The program can’t start because mfplat.dll is missing from your computer.”

In other circumstances, the Media Feature Package does not come pre-installed with the main Windows package especially for those who use Windows N, thereby causing the error to pop up. The main cause of this problem is that users who use Windows 10 N do not have the Media Feature pack pre-installed with the installation package. Aside from that, the installation package could go missing after a few Windows Updates or if you have uninstalled it by accident. To resolve this problem, you need to check out each one of the given options below.

Option 1 – Try to 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 2 – Try installing 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 have verified that your PC 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 3 – Try to extract 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.
