New Windows vulnerability discovered

The MP4 MIME-type is a video type that is mainly configured in IIS or Internet Information console. It is the one that instructs a web browser to use the default video application when running MP4 files from websites. MIME which stands for Multipurpose Internet Mail Extensions which offers a way to identify files on the Internet-based on their format and nature. For example, when a content-type header value like MP4 is defined in an HTTP response, the browser can be configured to open the file with the proper plugin. However, there are some servers that don’t have an associated MIME type to support MP4 files and so they fail to play these files. In such cases, you will encounter the “Unsupported video type or invalid file path” error, especially when you use the Internet Explorer browser in Windows 10. To fix this problem, you may have to configure the MP4 MIME type in IIS but you might find that IIS is not enabled in Windows 10 which is why you need to turn it on or enable it first. For more details, refer to the following instructions below.

Step 1 – Enable IIS:

• Open Control Panel and go to Programs > Programs and Features.
• From there, select “Turn Windows features on or off” to mark its checkbox.
• After that, select “Web Management Tools” and expand its menu and look for “IIS Management Console”.
• Click the OK button and then wait for a couple of seconds to allow Windows to successfully apply the changes made.

Step 2 – Configure the MP4 MIME type in IIS:

• Go to Control Panel and from there, access Administrative Tools.
• Next, click “Internet Information Services Manager” from the list of given options.
• Once confirmed, it will open the IIS console where you have to click the name of your IIS Server located on the left panel. This will enable several options in the central details section.
• Now double click on the icon with the label “MIME Types”.
• After that, you should see an “Add” link option on the right panel. Click on the link to open a configuration dialog box.
• Then type “.mp4” in the File Name Extension field and enter “video/mp4” in the textbox of the MIME Type.
• Click the OK button to save the changes made. This should fix the “Unsupported video type or invalid file path” error on your Windows 10 computer.

Step 3 – Reset your browsers:

Mozilla Firefox

• Open Firefox and click the icon that looks like three stacked lines located at the top-right section of the browser.
• Next, select the question mark icon from the drop-down menu.

If you suddenly receive an error saying, “Error 105 (net:: ERR NAME NOT RESOLVED): Unable to resolve the server’s DNS address” when browsing the web, then this means that the DNS lookup has failed. This kind of error is one of the most commons ones you can encounter while using the Chrome browser. And since it’s a pretty common error, the solutions for this one are pretty easy as well.

Option 1 – Disable both the Antivirus and Firewall temporarily

There are times when antivirus programs and the firewall blocks a website that they consider to be malicious or even because of false-positive effects. Thus, you need to disable these programs temporarily as it might be the reason why you’re getting the “Error 105 (net:: ERR NAME NOT RESOLVED): Unable to resolve the server’s DNS address” error in Chrome.

Option 2 – Check the Network Cables and restart the router then reconnect

Of course, the next thing you have to do is to check if the network cables connected to your computer or router are properly connected. And if your computer is connected via Wi-Fi, you need to make sure to restart your router once. In addition, you can also forget the Wi-Fi your computer is currently connected to and then try reconnecting again to see if it would work.

Option 3 – Try running the Chrome Cleanup tool

You might want to run Google Chrome’s built-in Malware Scanner & Cleanup tool as it could also help in getting rid of any unwanted ads, pop-ups, and even malware, as well as unusual startup pages, toolbars, and anything else that might overtake the network and could affect the performance of the browser.

If you encountered an error message that says, “Unhandled exception has occurred in your application”, when you start your Windows 10 computer, read on as this post will guide you on how you can fix it. This kind of error usually appears in a Microsoft .NET Framework window and it mostly pops up as soon as you turn on your computer. Here’s the complete context of the error message:

“Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.”

When this error occurs, your computer may freeze or display other suspicious behavior at times. Either way, there are several options you can check out in this post to resolve this issue, so read on. This kind of error could be caused by several factors. It could be due to your antivirus program or other third-party programs installed on your computer. It is also possible that the installation of the Microsoft .NET framework id corrupted or some of its installation files are corrupted. Thus, to fix the error, there are a few suggestions you need to follow such as:

Option 1 – Try to temporarily disable your anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed on your computer. Thus, disabling them or any security software installed in your computer is always a good idea you can try when you’re not able to access the shared drive in your computer. There are times when you encounter problems like the “Unhandled exception has occurred in your application” error due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program in the meantime and check if it fixes the error or not.

Option 2 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• 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”.

• 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.)
• Once your computer has restarted, check if the error is now gone. If it is, then the culprit is some third-party program. Thus, you have to enable the third-party programs one by one to find out which one of them is causing the the “Unhandled exception has occurred in your application” error.

Option 3 – Try to run a System File Checker scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be the cause why you’re getting the “Unhandled exception has occurred in your application” error. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Now restart your computer and see if the problem is fixed or not.

Option 4 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual check especially if you are getting this issue of abnormal program termination.

• Install some qualified drivers – A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.
• Download and install or Update DirectX – As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.
• Install the Microsoft DirectX End-user runtime – The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.
• Update or install the .NET framework – The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.

If you suddenly see a black border in your computer’s display then you might be wondering how come this happened but worry not for this post will give you a couple of suggestions that could help you resolve the problem.

Having the latest applications is often preferred for most users but sometimes we have some old applications which have not been updated or simply we just want to run oldie on our computer because it does everything we need and we do not want to upgrade in order to save some money. The issue is presented sometimes when we try to run an old application in Windows 10 and some components are missing in Windows itself or the application is simply coded in a way to work on older Windows versions. If by any chance you have this issue then this guide is for you since we are going to show you how to run old applications in Windows 10. This guide is made in a way to takes into account that the application itself is completely installed on your Windows 10 machine if you can not even install the application you will need to search solution for that particular application since that can not really be generalized and pinpointed issue, every application is different.

Running old applications using the compatibility option

All of that being said, let's start that old app you have. First thing is to locate an executable file or shortcut of the desired application. Once it is located, right-click on it to bring up the menu, and all the way to the bottom you will find properties. Left-click on properties. The application settings screen will open, in upper tabs locate Compatibility and left-click on it. After the click, you will find yourself in application compatibility settings. In this window, you will face different options to run the chosen application in various modes in order to make it run. How settings are self-explanatory and different applications will need different settings sadly we can not cover them all but your safest bet is to run them in an environment where they have worked. For example, if the application was working fine in Windows XP and required administrator privileges, check Run this program as an administrator and Run this program in compatibility mode for Windows XP.
