Unhandled Exception occurred in Application

If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites. If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:

“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”

And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.

Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs

Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.

Option 2 – Try to disable security.enterprise_roots.enabled

The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.

• Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
• After that, if an info message appears, confirm it.
• Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
• Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.

Recently, a number of Windows 10 users reported that they were not able to use Cortana properly because it wasn’t able to connect to the internet. According to these users, Cortana won’t connect to the internet even when their internet connection is stable. According to security experts, this issue is confirmed to occur only with Microsoft accounts. This problem might have something to do with a proxy server that interferes with Cortana. There were reports that this issue was caused by a proxy that was filtering the network connection which also happens to interfere with Cortana’s ability to adapt search results and queries based on the user’s location. It could also be caused by some glitch in the home network or your Microsoft account information is inconsistent or your Microsoft account has to be verified. Here are some suggestions that could help fix the connection issue in Cortana, just start with the first one and work your way down until you encounter an option that fixes the problem.

Option 1 – Restart or reset your modem or router

The first thing you can try is restarting or resetting your modem or router. All you have to do is unplug the power cable of the modem and then plug it back in after a few seconds. You could also use the reset button of the modem at the back if it is one. But before you press the reset button, keep in mind that it will erase all the connection credentials and it will be set back to its default settings. After rebooting the network, you can restart your computer to force your modem or router to reassign an IP address to your computer.

Option 2 – Restart Cortana

Restarting Cortana can help you resolve the issue.

• To restart Cortana, open the Task Manager, right-click on Cortana and select the “End process” option.
• Then go to the File tab and select “Run new task”.
• After that, type in “cortana.exe” and press Enter to restart the process.

Option 3 – Try to remove Proxy

Removing the Proxy might also help you in fixing the connection issue in Cortana. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 4 – Open another app that uses a Microsoft account

This might seem like an odd fix, however, a couple of users tried doing this and it worked for them as it allowed Cortana to connect to the internet again. In this option, you just have to launch another app that uses your Microsoft account information in the same way as Cortana, for instance, the Store app. Once you open the app, a prompt should appear along with a dialog box that allows you to update your Microsoft account with the information required. After that, restart your computer and check if Cortana is now able to connect to the internet or not.

Option 5 – Verify your Microsoft account

In some cases, Cortana might not be able to connect to the internet because your Microsoft account is no longer verified. This usually happens when you use a two-step authentication system with your Microsoft account. To verify it, just open Settings and click on Accounts. After that, check if you have a Verify hyperlink under your Microsoft account or not then click on Verify. Afterward, follow the next on-screen prompts to verify your Microsoft account. Once your account is verified, restart your computer.

Option 6 – Reset Cortana settings

• Open Cortana and go to the Settings section where you’ll see the “Turning off Cortana clears what Cortana knows on this device, but won’t delete anything from the Notebook. After Cortana is off, you can decide what you’d like to do with anything still stored in the cloud” option. Turn this option off.
• Restart your PC.
• After your computer boots, launch Cortana again and check.

In case you don’t know, Windows contains a feedback mechanism that generates error reports from hardware and software problems. These reports are temporarily stored in the system and send them back to Microsoft so that it can find solutions to the reported problems and fix them in the upcoming updates.  However, as time goes by, these reports actually take a lot of space in your computer which is why end-users like you are free to delete them with the help of the new Free Up Space feature in Windows 10. As useful the Free Up Space feature may be, there are times when you won’t be able to use it for some reason which is why in this post, you will be guided on how to use alternative ways in deleting very large System queued Windows Error Reporting file, some of which may run in Gigabytes. Every time the Windows Error Reporting or WER sends out an error file and looks for a solution, the WER server at Microsoft sends out a solution instantly. And if the solution is under investigation or is unknown, then you will be notified about it right away and will be asked for more details. As mentioned, even though the Free Up Space feature in Settings will be able to clear the error reporting files, there are instances when it won’t be able to delete very large System queued Windows Error Reporting files. Alternatively, there is an option to delete these files using the Disk Cleanup Utility. Feel free to select which option you’d like to use to get rid of Windows Error Reporting Files.

Option 1 – Delete Windows Error Reporting Files via Settings

• Go to Settings.
• From there, go to System > Storage > Free Up Space and then click on it to launch it.
• Afterward, give it some time to populate all the files and folders. Once it’s done, select “System created Windows Error Reporting files” to mark its checkbox while leaving the other options unchecked.
• Next, click on the Remove files button to delete all the Windows Error Reporting files from your computer.

Option 2 – Manually delete the Windows Error Reporting Files

• Tap the Win + E keys to open File Explorer.
• Next, enable the Hidden Files view from the menu.
• Then go to C:/ProgramData/MicrosoftWindowsWER.
• From there, you will see various folders like LocalReportArchive, ReportArchive, ReportQueue, and Temp.
• Open each one of the aforementioned folders and delete the archive files. Note that these files will have names similar to “00c58c1f-b836-4703-9bcf-c699ca24d285”.

Note: If you are not able to delete any of these files, you have to take ownership of the folder. To do so, refer to these steps:

• Right-click on the folder and then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.

On the other hand, if you do not want to go through all these troubles in deleting the Windows Error Reporting files, you can just disable it especially if it already becomes a daily annoyance as the files generate every day and their sizes are mostly gigabytes. And besides, there are times when these files do not make it to the Microsoft WER server and end up only occupying a lot of space for nothing.

If it didn’t work, you can try to execute this command instead: FOR /R C: %G IN (*.dll) DO "%systemroot%system32regsvr32.exe" /s "%G"
• Once it’s done, restart your computer.

Windows has a lot of built-in tools that help you fix tons of system-related issues. One of them is the System File Check which is the tool you can use to conveniently replace potentially corrupted or missing system files with good ones. But what happens when it does not work? Well, you’ve come to the right place as in this post, you will be guided on how you can replace a corrupted single Windows system file manually with a known good copy of the file if the System File Checker scan is not working. When you encounter this issue with the System File Checker, it will be unable to replace the corrupted system files and returns an error message instead. And so to fix and replace corrupted system files in your Windows 10 computer without the help of System File Checker, you can refer to the instructions provided below. Step 1: First, you need to open the log files listed below and identify which particular file has been corrupted:

• %userprofile%Desktopsfcdetails.txt
• Log %WinDir%LogsCBSCBS.log

Step 2: You will see all the details on the given log files. Once you find out the name and the path of the file, you have to take ownership of this corrupted system file. Step 3: To take ownership of the corrupted file, you need to pull up Command Prompt by tapping Win + R keys on your keyboard and then type “cmd” and tap Enter. Step 4: After opening Command Prompt, type and enter the command below to execute it:

takeown /f FileNameAndPath

Note: In the given command, “FileNameAndPath” represents the name and the path of the corrupted file. For instance, the corrupted file is named “wuapi.dll”, then you need to type “takeown /f C:/Windows/System32/wuapi.dll” Step 5: Next, you need to grant administrators full access & control to the corrupted file and you can do that via Command Prompt again. Step 6: In the elevated Command Prompt, type and enter the following command to execute it:

icacls FileNameAndPath /GRANT ADMINISTRATORS:F

Note: We’re going to use the wuapi.dll again as an example. So the command should be like this: icacls “C:/Windows/System32/wuapi.dll /grant administrators: F”. Step 7: Now all that’s left to do is replace the corrupted system file with a good copy from a trusted source. Once you have a copy, open an elevated Command Prompt again and execute the following command:

copy NewFileLocation FileNameAndPath

Note: In the command given above, the “NewFileLocation” is the location where you have saved the copy of the file. For instance, if you’ve saved it on your desktop, this is how it should look: “copy C:/Users/<username>/Desktop/wuapi.dll C:/windows/system32/wuapi.dll”
