How To Fix Error 0x00000050

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”.
• Clear the “Load Startup items” check box 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.)
• 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 have encountered the NO_USER_MODE_CONTEXT Blue Screen error when using your computer, read on as this post will walk you through a couple of suggestions you can try to resolve this Stop error. This kind of Blue Screen error can occur when a program is trying to leverage the use of a system driver but fails to do so. Some of the common causes of this BSOD error are incompatible or corrupted drivers, incorrect configuration of entries in the Registry, damaged memory locations, malware infection, and many more. In addition, this Stop error does not often occur and indicates that an attempt to enter user mode with no context was made. If this is the first time you’ve restarted your computer after you’ve installed additional hardware, you have to remove the hardware and then restart your computer once again and then check the Microsoft Hardware Compatibility List to confirm that the hardware and its drivers are compatible with your operating system. If it doesn’t help, you can check out the given suggestions below to fix the NO_USER_MODE_CONTEXT Blue Screen error in Windows 10.

A black screen error inside Windows 11 is a typical screen turning to solid black without any error message. This can be very annoying since it can randomly appear out of nowhere and it will appear while you are using the computer. Worry not, this is not a serious error and we have several solutions for it, so please keep reading and try them as presented in order.

Restart graphic driver

This is the first thing to check if the issue is due to software or driver malfunctioning, there is a shortcut for rebooting graphic driver inside Windows 11. Press WINDOWS + CTRL + SHIFT + B to reboot the graphic driver and see if this fixes the issue. A beep sound should be heard during this process and the screen should turn back to normal.

Check connections

Sometimes the screen can go black due to a faulty connection or cable. If you have it at your hand try a different cable or slightly and gently nudge the existing one to see will screen flicker. If you are on a laptop try gently moving the lid from back to front and pay attention to the screen. If screen flickers or picture returns with this method, cable or connector needs to be replaced.

Clean your computer

The black screen can be because the computer is overheating. If this is the case either fan inside is not working properly or there is a lot of dirt and dust that needs to be removed so airflow can be established again for proper cooling.

If you own an iPhone, iPad, or iPod you might be aware of the phenomenon of connecting and disconnecting your device. In one moment device is connected and then it somehow loses connection and you have to plug in back again to be recognized. In this troubleshooting guide, we will address ways to eliminate this issue and to connect and have your devices working properly. We will go from the most common ones to the most uncommon so it is advisable to try solutions in order to how they are presented.

1. Check cable

   The most common issue with this kind of behavior comes from a broken cable if you have the opportunity try another working cable to see if the device will behave differently. If everything is working fine with another cable, the issue is in the previous cable.

2. Check USB ports and Cable Jack

   Usually, it is a cable issue, but it can also be a USB jack on cable or even a USB port on a PC, try putting the jack into another port to see if this will solve the issue.

3. Check device settings

   From updates on your device comes a change of setting about privacy which can reflect on connection with the computer. In order to eliminate this, you will need to reset your device. Go to device settings and go to general Scroll down until you find the reset section and go into it In the reset, section click on reset location and privacy You will have to authenticate using your pin/passcode in order to complete the reset function Enter your passcode (or use any other authentication method you have chosen) and you can now reset the Location and Privacy settings. Click on reset Connect the device to PC and choose trust this device

4. Update iTunes

   Outdated iTunes can also be a problem with this particular issue. Go to the apple website and download the latest version of iTunes or updating it via apple updater.

There are cases when you encounter some issues while updating your Windows 10 computer. One of these issues is the error 0x80240034. This particular error is a Windows Update Error that appears on the Windows Update pane every time an update fails to install. When this happens, your Windows Update will only get stuck at 1% and nothing happens afterward and eventually fails. If you click on the View Installed Update History, you will see the error code 0x80240034 for the failed updates. You will see this error each time you try to update your Windows PC. Take note that this issue doesn’t only happen to a specific version of the Windows Update but on various different Windows builds based on many users. What’s more, is that some users are also seeing a different error code when their Windows Update fails but they still end up seeing the error code 0x80240034 when they check the Windows Update history. At the time of writing, it isn’t determined yet what really causes this error but it’s most likely due to some corrupted files in the computer which is why the most common solution you can try is resetting the Windows Update cache. On the other hand, other users also resolved the issue by using the ISO and selecting the “Do not keep previous settings” option during the Windows Update so it might be something to do with transferring the previous settings through the update client. For clear instructions in fixing this issue, refer to the two options provided below.

Option 1 – Try to clear the Windows Update Cache/Distribution Folder

As mentioned earlier, a lot of users tried clearing the Windows Update cache to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Step 1: Tap the Windows key once.
• Step 2: Next, type in “command prompt” in the Windows Start Search, and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option from the context menu.
• Step 3: After opening Command Prompt, type in “net start wuauserv” and hit Enter.
• Step 4: Then type in “rmdir %windir%SoftwareDistribution /S /Q” and hit Enter.
• Step 5: Now type in “net start wuauserv” and hit Enter. Once it’s done, try updating your Windows PC again, it should now work just fine.

Option 2 – Update Windows via ISO file

If option 1 didn’t work for you, you can try this second option of updating your Windows 10 computer using an ISO file which means that you will have to create a Windows 10 bootable media and use it to install the latest Windows 10 version. The most user reported that this option works and the reason why it does have something to do with the Windows Update client since the Windows Updates downloaded from the regular Windows Update client seems to create issues such as the error 0x80240034. However, issues like this one don’t occur when the very same Windows Updates are downloaded and installed via an ISO file. Take note that when using a Windows ISO file, you will be asked to choose what you want to do with the previous settings and apps. A lot of users opted for the “Not to keep the old Windows settings” option which has resolved the issue. So if you want to keep the previous settings then you must try to update Windows first while keeping the old settings. However, if it doesn’t work, you have to try installing the latest version of Windows without keeping the previous settings.

• Step 1: Click this link and then click the Download Tool Now button.
• Step 2: Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
• Step 3: Now select the ISO file option in step 5.
• Step 4: After that, you should now have an ISO file.
• Step 5: Next, go to the location where you’ve downloaded the ISO file.
• Step 6: Then right-click on the Windows 10 ISO file and select the Open with an option and then select File Explorer.
• Step 7: Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either: Nothing (clean install) or Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

Facebook has an algorithm inside it that can recognize your face in pictures and videos which is meant to help people tag friends when they upload media into Facebook. It is a neat feature meant to help all Facebook users but what if we do not want to be detected in pictures and videos? What if we do not want to be tagged? If you are one of the Facebook users that do not wish to be detected and recognized by Facebook in media keep on reading to find out how you can disable this option.

1. Open the Facebook website and log into your account.
2. Click on the arrow visible in the top menu bar.
3. Select the Settings & privacy option.
4. Click on the Settings option.
5. Switch to the Face recognition tab on the left-hand side.
6. Click the Edit button.
7. Select No from the drop-down list.

And you are done, you do not need to log out or restart facebook in order for changes to have an effect. Now you are free from face recognition and detection.

Error Code 80070103 –What is it?

Error code 80070103 affects Windows users who attempt to access the latest updates for hardware drivers using Windows Update. Windows 10 users who are affected by this error code will be unable to complete the upgrade process. This error code usually occurs due to the Windows Update attempts to download an incompatible version of a driver or a driver that is already downloaded on one’s device.

Solution

Error Causes

The cause of error code 80070103 in Windows 10 is usually easy to determine. This is due to the fact that the error code only affects users who attempt to access updates related to hardware drivers. In such cases, the error code will only occur if the Windows Update website or tool on your machine attempts to install a driver that is already present on one’s machine or the version of the driver is unsuitable for one’s machine due to lower compatibility.

Further Information and Manual Repair

Manual repair methods are very effective in helping Windows users fix problems related to error code 80070103 as well as other errors. These repair methods can usually be implemented by users with very limited technical skills. In some cases, however, you may need to contact a Windows repair technician, i.e. if you have problems following the manual repair method instructions provided or if the repair methods prove unsuccessful.

In the case of error code 80070103, the problem can be rectified by either hiding the update or reinstalling the hardware driver. Windows users can hide an update on the Windows Update website or via Windows Update within their machine’s Settings. However, users will need to contact their device manufacturer to reinstall hardware drivers in most instances. See below for further details regarding these manual repair methods.

Method One: Hide the Update

In the case where you are informed via an error message box that a driver, for instance, your graphics driver, is incompatible you may need to consider hiding the update to prevent error code 80070103 from reoccurring on your machine.

The incompatible issues will come about when the Windows Update website attempts to download a driver that is already on the device or one with a lower compatibility. When you hide the update, it is in essence, preventing Windows Update from offering this driver in the future. To complete this manual repair method, follow the steps below:

• Step one: Visit the Microsoft Update site 
• Step two: Select Custom on the Welcome page after completing the scan for the updates process
• Step three: Select Hardware, Optional.
• Step four: Open the second update for the graphics card, then select Don't show this update again check box.
• Step five: Review and install updates.

You may also complete this process by opening Windows Update within your computer’s settings, then selecting the Optional update or available link. Once you’ve done this, you may then select the updates you would like to install and hide the update that has resulted in the occurrence of error code 80070103.

Method Two: Reinstall Hardware Driver

In the case where you need to install a hardware driver, you will need to contact the manufacturer of your device. Once you’ve contacted the manufacturer or visit the manufacturer’s official website, you can then install the latest device drivers manually. Read the instructions for the installation of the latest drivers carefully. This will ensure you avoid any problems and improve your chances of successfully fixing error code 80070103.

After you’ve contacted your device manufacturer and completed the process of reinstalling the hardware driver, check Windows Update to see whether or not error code 80070103 has been rectified. If the problem was related to your hardware driver and you successfully reinstalled the driver, the error code will not reoccur when you attempt to download the latest updates for your hardware drivers.

However, you may need to take another approach if this manual repair method fails to fix error code 80070103. For instance, consider getting help from a Windows repair technician who is equipped with the skills and expertise necessary to offer a detailed inspection of your machine. Though the error code is related to one’s drivers, the fact that a Windows error code occurred may mean that your system needs a thorough evaluation as other issues may be present.

Method Three: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.
