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.

In case you don’t know, Microsoft Edge, the new default browser of Windows 10, is equipped with the essential tools that are needed to help web developers in testing their websites in the Edge browser. However, it is not without its flaws as there are instances when you could also encounter some errors when using DevTools. One of these errors is the “An error occurred while starting the profiling session” error. You can see this error message in the DevTools Memory Panel, worry not for this post will help you resolve it. A memory panel is one that primarily measures your memory resource usage and compares heap snapshots in different states of code execution. The Memory panel also provides profiling of three different types, such:

• Head Snapshot
• Record Allocation timeline
• Record Allocation profiles

Using a memory panel, you can find issues that affect the page performance in the most common scenarios like bloats and memory leaks. There are two steps you need to carry out to fix this error that’s associated with the Memory Panel of Microsoft Edge (Chromium) DevTools. First, you need to access the Microsoft (R) Diagnostics Hub Standard Collector Service. Second, you need to restart this service. For detailed steps, follow the instructions provided below. Step 1: Access the Microsoft (R) Diagnostic Standard Collector Service To access the Microsoft (R) Diagnostic Standard Collector Service, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “services.msc” in the field and hit Enter or click OK.
• This will open the Services Manager. Here, look for the Microsoft (R) Diagnostic Service from the Services panel that opens on the right-hand side.

Step 2: Now restart the Microsoft (R) Diagnostic Hub Standard Collector Service

• After accessing the Microsoft (R) Diagnostic Standard Collector Service, right-click on it and select the Restart option.
• Once it’s done, exit the Microsoft Edge Developer Tools as well as the tab.
• Next, open a new tab and navigate to your page and tap the F12 key.
• Now, try to check if profiling begins.

One of the most useful utilities on a Windows 10 computer is the Windows File Explorer. It is undeniably one of the File Managers out there full of features on all the platforms. However, it is not without its issues and one of the most common ones most users encounter is when you are trying to open a folder or a location on File Explorer and it displays a message saying, “Working on it…” as it tries to load the content of that location or folder. This kind of issue mainly occurs to computers that run on an HDD although that doesn’t mean that it can’t happen to other computers that run an SDD. And so if the File Explorer on your Windows 10 computer keeps getting stuck on the “Working on it…” message along with a green animation bar moving very slowly while loading the contents of the folder, then it’s best if you follow the options given below to resolve this problem.

Option 1 – Try deleting the contents of the Automatic Destinations folder

• Tap the Win + R keys on your keyboard to open the Run utility.
• And then type “%AppData%MicrosoftWindowsRecentAutomaticDestinations” and hit Enter to open this location.
• From there, select all the files and tap the Shift + Delete key combination.
• After that, you will get a prompt that will ask you if you want to delete all the files permanently, just click on Yes. This will delete all the Quick Access cache.
• Now check if you can now open a folder or a location without the “Working on it…” message.

Option 2 – Try to rebuild the Search Index

• First, open the Indexing Options using the Search bar.
• Next, click on the appropriate listing, e.g. Users folder.
• After that, click on the Advanced button. This will open a mini-sized window and from there, go to the Index Settings tab.
• Then click on the “Rebuild” option under the Troubleshooting section.
• Now click on OK after the rebuilding is completed. This should rebuild the search index for all the files and thus, fix the File Explorer stuck on the “Working on it…” message.

Option 3 – Try to optimize the folder for General Items

You might also want to try optimizing the folder for General Items as it can help the File Explorer to load the contents faster.

• Just right click on the folder that takes time to load the contents in it and is showing the “Working on it…” message.
• After that, click on Properties to open the Properties mini window.
• From there, go to the Customize tab and click on the drop-down menu to “Optimize this folder for” under the “What kind of folder do you want?” section and then select General Items.
• Then check the checkbox with a label that says, “Also apply this template to all subfolders” and click on the OK button to save the changes.
• Restart File Explorer and check if the problem is now fixed or not.

Option 4 – Try performing a System Restore

Running System Restore can also help you resolve whatever issue that’s causing the “Working on it…” message. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Update and Shutdown/Restart is not working. As you have probably noticed, every time a new update is released and is downloaded on your Windows 10 computer, the operating system replaces the Restart and Shut down button with “Update and Restart” as well as “Update and Shut down”. This is most likely done so that you won’t miss the update. However, some users noticed that there are times when these buttons still continue to display the same message even if they’ve already performed the required operations such as shutting down or restarting their PCs. Cases like this happen when an update wasn’t installed properly or has failed which is why your computer keeps on prompting you to Update and Shutdown every time. To fix this dilemma, follow the options laid out below.

Option 1 – Try restarting the File Explorer

Restarting the File Explorer can definitely help you fix lots of issues especially when there is some issue with the user interface including this one.

• On the right side of the Taskbar, right-click on any open spot.
• Then click on Task Manager.
• Next, scroll down until you see Windows Explorer.
• After that, right-click on it and select Restart.
• If you are able to kill its process, you have to tap the Win + R keys to open the Run dialog box and type “explorer.exe” in the field, and hit Enter to launch the Windows Explorer.

Option 2 – Try running the Windows Update Troubleshooter

As you know, Windows 10 has various auto-repair built-in tools to help users fix small issues which used to get fixed manually. And in this case, you will need the Windows Update Troubleshooter to fix the issue.

• Go to Settings and click on Update and Security.
• From there, click Troubleshoot and click on Windows Update and then click the “Run the troubleshooter” option.
• After that, it will try to detect and automatically fix common issues in the Windows Updates which can be resolved by Windows itself. Note that the process may take several minutes before it completes so you need to wait until it’s done. Once it’s done, in case you have some pending update that wasn’t realized by the system early on, it will apply the fix right away and restart the Windows Update service.

Option 3 – Try setting the Power button to Shut down

In case the first two options didn’t work out, you can try changing what the power button does. To do that, refer to these steps:

• Go to Control Panel > Power Options.
• From there, select the “Choose what the power buttons do” option from the left side.
• Then set the Power button setting the “When I press the power button” option to “Shut down”. After that, it will shut your computer down without installing the updates but obviously, this is only a temporary fix.

Option 4 – Turn off your PC instantly without updating it

• Tap the Win + R keys to open the Run dialog box.
• Type in “shutdown -s -f -t 0” in the field and hit Enter if you really want to turn off your computer without any delay.
• You could also tap the Ctrl + Alt + Del keys and select Shut down from the bottom right menu.

Just like the third option, this is also only a temporary fix.

Option 5 – Try running the Windows Module Installer

The Windows Module Installer is a built-in service in Windows 10 that allows you to fix the stuck Windows Updates in your computer. To use it, follow these steps:

• In the Cortana search box, type in “cmd” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• Once you’ve opened Command Prompt as admin, type the SC config trustedinstaller start=auto command and tap Enter.
• After the command is executed, you will see the “[SC] ChangeServiceConfig SUCCESS” message displayed on the Command Prompt console.
• Now exit Command Prompt and then check if the buttons are now back to normal.

Option 6 – Put your PC in a Clean Boot State

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

Installer Error 1603 - What is it?

Installer Error 1603 message occurs during the installation of the Microsoft Windows installer Package. The error message is often displayed as the following:

'Error 1603: A fatal error occurred during installation.'

It indicates a problem occurred during the installation process and unsuccessful installation.

Solution

Error Causes

The installer error 1603 may occur if:

• The folder you are trying to install the Windows Installer package to is encrypted
• The system account does not have full control permissions
• Incorrect installation
• Registry issues

The Google Chrome browser checks the SSL Security Certificate of the website that you are trying to open. However, if Chrome is not able to check the certificate then you might encounter an error related to the SSL Certificates which you might face when browsing the web. This particular error is the ERR BAD SSL CLIENT AUTH CERT error which is caused by many factors such as the computer’s Time, Cached Data is corrupt, Date is out of sync, as well as third party software installed in your computer is the one that’s blocking the site and many more. The ERR_BAD_SSL_CLIENT_AUTH_CERT error might also be coming from the website’s end. It could be that the server is rejecting the certificate the client website is sending. The certificate might have already expired or the server may not trust its issuer – whichever the case may be, here are some options you can check out to fix the error.

Option 1 – Sync Date and Time

The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the ERR_BAD_SSL_CLIENT_AUTH_CERT error. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.

• Right-click on the Taskbar and click on the Adjust Date and Time option.
• Next, click on the Sync Now button to synchronize the Date and Time with the Microsoft Servers.
• Now make sure that the Time Zone that’s set on the same page is correct.

Option 2 – Try clearing the browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BAD_SSL_CLIENT_AUTH_CERT. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.
• Now select every checkbox that you see and click on the Clear browsing data button.
• Then restart your Chrome browser and check if you can now open any website or not.

Option 3 – Try to check and fix any possible conflicts with third-party programs

Third-party programs like internet protection software could be interrupting the connection and causing the error. For some unknown reason, your antivirus program or firewall might be detecting the webpage you are trying to open as malicious or with less credibility which is why it is blocking the browser from opening the website. To fix that, if you have third-party programs installed like VPN, security software, or any add-on, or firewall, you can disable them temporarily and see if it fixes the problem and you’re able to pull up the website. After a while, you have to enable them back and configure their settings so that the website won’t get blocked again.

Option 4 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR_BAD_SSL_CLIENT_AUTH_CERT error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on. If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.

• Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
• Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
• From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.
• Restart the browser.

On the other hand, if you were using Firefox when you go the error, here’s what you have to do.

• Open Firefox and in the address bar, type “about:config” and hit Enter.
• If a warning appears, just click on the “I accept the risk!” button to proceed.
• Next, type in “TLS” in the search field and hit Enter.
• Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
• Now click OK and restart Firefox and do the same thing with SSL.

Option 5 – Try to update Google Chrome

You might also want to try updating your browser to its latest version and have it installed in your computer. After you install the update, check if you can now open the website you were trying to open earlier.

Option 6 – Get rid of any conflicting browser extensions

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
• Click the Recycle bin and select Remove.
• Restart Chrome and press Alt + F keys again.
• Proceed to On Startup and mark Open a specific page or set of pages.
• To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.

Note: If removing the browser extensions or toolbars didn’t work, you can also try to reset your Google Chrome browser.

• Open Google Chrome, then tap the Alt + F keys.
• After that, click on Settings.
• Next, scroll down until you see the Advanced option, once you see it, click on it.

If you recently upgraded your computer or if you’ve just switched to a new Windows 10 PC, the most common errors you might encounter are the Windows Activation errors. This issue boils down to the Windows Activation server which has either failed to validate or recognize the license tied to the digital account. In this post, you will be guided on how to fix an activation error in an organization with an error code 0x8007007B. It contains this exact error message: “We can’t activate Windows on this device as we can’t connect to your organization’s activation server. Make sure that you’re connected to your organization’s network and try again. If you continue having problems with activation, contact your organization’s support person. Error code 0x8007007B.” Various computers are activated via the KMS licensing (Key Management Server) in organizations. Computers that are activated using this process do not get a permanent activation and have to stay connected to the organization instead of for at least 7 months or 180 days. It is common in Pro and Enterprise versions that are deployed in bulk for at least hundreds or thousands of computers. So imagine a user with a personal computer in the office who decided to leave the organization but will still have an activated Windows key. And so to prevent that from happening, organizations use the KMS licensing. Another possible cause of the error is in case some user used an organization key and later on, the PC just got upgraded or downgraded to a version that is not compatible with that copy of Windows. To fix this Windows Activation error, here are some suggestions that might help.

Option 1 – You can try connecting to the organization’s network and activate the computer. But before that, you need to first check if the computer actually belongs to an organization or not.

• Tap the Win + R keys to open the Run dialog box.
• Type “cmd” and hit Enter to open an elevated Command Prompt.
• After that type the vbs /dlv command and hit Enter to execute it.
• Next, check if the Product Key Channel says “GVLK”. If it does, then it means that your computer was activated using volume licensing.

Option 2 – Change Licence Key

If you’ve recently left an organization then it’s best if you buy another copy of Windows 10 and then change the license key. This time, make sure that the license key is for the same version of Windows. However, if it’s different, you need to format your computer.

Option 3 – You can try activating Windows 10 using a mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 4 – If you think that the issue is caused by some hardware changes, you can try using the Activation Troubleshooter.

There are times when users already have the license keys and were able to activate Windows. However, it doesn’t last long and only works for a while and it’s suddenly throwing up an activation error like this one. To use the Windows Activation Troubleshooter, just go to Settings and to Activation and then run the troubleshooter from there. If you've made some modifications to your hardware, you have to click the “I changed hardware on this device recently” option for further suggestions.
