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.

Still sitting on the fence about upgrading to Windows 11 because you don’t know what to expect? Interestingly, the new edition somehow manages to be both a total revamp and still very similar to its predecessor in many ways. It’s really something to experience for yourself.

We do want to give you a sneak peek, though. So here’s an overview of the biggest changes Windows 11 brings to the table.

What’s different in Windows 11?

1. Visual changes

The first thing anyone will notice after switching to Windows 11 is the striking visual difference. The entire interface is smoother, cleaner and more minimalistic than on Windows 10, even resembling the macOS in some instances.
Perhaps the most obvious change in appearance is the Start menu and Taskbar location, which is now at the bottom center. It’s actually very neat, but if you’re someone who loves familiarity, don’t worry, you can move it back to the left.

Moreover, you’ll notice that the Taskbar includes a Microsoft Teams icon by default (which you can, of course, remove) and that Live Tiles are gone. The News and Interests section has also been removed - or, shall we say, replaced. As opposed to Windows 10, news, weather forecasts and other information are now displayed as widgets.

To add to the cleanliness of the UI, Microsoft also enhanced the ‘Snap Layouts’ feature to help you better organize your windows and maximize screen real estate. It’s similar to app grouping on your smartphone. In Windows 10 this feature is slightly restricted, as it requires some manual resizing and dragging. In Windows 11, you can just hover over the minimize/maximize option on a window, select a layout and throw the windows in there. 

2. New accessibility features

Microsoft has certainly paid attention to accessibility with Windows 10, but Windows 11 takes this to a whole new level.

One of the ways Windows 11 has taken things up a notch is by adding the long-awaited ‘Live Captions’ feature and advanced Narrator options.

Live Captions apply both to media played on your PC as well as your own speech when you’re using the microphone. Keep in mind that, as with almost all kinds of subtitles, you have to be prepared for a potential delay. However, it’s barely noticeable and doesn’t take away from the usefulness of this awesome new feature whatsoever.

As for the Narrator, there are three new voice packs to choose from. Microsoft has tried to put emphasis on a more natural voice than we are used to. So, now you can choose between Aria, Jenny and Guy, who will read pretty much anything off your screen out loud. Aside from this, Microsoft has also expanded the list of braille displays supported by the Narrator feature. 
For users with anxiety or trouble concentrating, a welcomed addition is the Focus app, which is no longer part of the Clock app. It’s now separate and called ‘Focus Sessions’, automatically triggering the Do Not Disturb mode when activated. It blocks all pop-ups and flashes and lets you work in peace until you’re ready to switch it off.

3. Android apps

Android users may rejoice! Windows 11 supports the use of your favorite applications now. 

Microsoft has done this by integrating the Amazon Appstore to the Windows 11 Microsoft Store. From there, you can download your favorite Android apps and use them on your PC in a smartphone-like window.

Unfortunately not too many apps are supported at this time, but Microsoft is working on making the emulation possible for many more. Also, the option is only available in specific regions at this moment - check out if you’re one of the lucky ones.

4. Improved gaming performance

Avid gamers will be happy to hear that Microsoft has put some effort into streamlining Windows 11 for their gaming needs.

To give gamers a supreme visual experience, Windows 11 offers the ‘Auto HDR’ feature. As long as your monitor is HDR-compatible, this feature will automatically adjust the colors, brightness and contrast of games without any input from you. 

Another update is DirectStorage, which we were introduced to in Windows 10 already. In Windows 11, it’s been improved to tweak loading times and overall gaming performance efficiency even better. The predisposition for it to work optimally is that your device has an NVMe SSD. 

The Xbox Game Bar also helps gamers towards a smoother experience. It allows in-game screenshots, viewing processes that are running (similar to the Task Manager), monitoring the CPU and GPU performance and frame rate, integrating the Xbox App and more. There’s also a number of widgets you can now use with the Game Bar, for example the Spotify widget.

Another cool addition is the Xbox Game Pass, which unlocks hundreds of games to play on your Xbox App, with new additions coming in every month.

5. Smart App Control

Aside from a sleek new look and better accessibility for all users, Windows 11 also comes with a security power-up. Bear in mind that this feature is only available on clean Windows 11 installs. 

Smart App Control (SAC) is an AI-powered new feature designed to protect your PC from potential threats. It blocks untrustworthy apps and adware and helps detect potentially unwanted apps, maintaining your PC’s performance and keeping your system safe.

It comes with an ‘Evaluation’ mode, which you should definitely select when running SAC for the first time. That way, the app monitors your usage and assesses whether you’re a candidate for SAC. Some users need it to be on all the time, for others it might be too distracting. Evaluation mode will turn SAC on or off based on your usage.

Don’t disable SAC again unless you’re absolutely sure you don’t need it, since reenabling it will require a fresh install. We recommend you don’t turn it off, as it is a neat feature protecting your data and files from malware at all times.

Summary

Have we piqued your interest in trying Microsoft’s latest OS? It’s a pretty exciting new iteration, but we’ll let you find out for yourself. We hope you like it!

Interrupts are designed so that the resource requests don’t get into a headlock when it comes to the hardware level. To simply put it, it is used to break a loop that never ends. Aside from that, developers also designed levels in order to prioritize interrupts. It is also known as “Interrupt Request Level” or IRQL. And if you suddenly encounter a “Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL” error, this means that a driver has accessed a memory location illegally while NT is operating at a specific IRQL. The Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL is a fatal driver coding error and as an end-user, there isn’t much that you can do to resolve it but if you’re a developer, then this means that your code is trying to access an invalid memory location. You could check on different parameters such as memory location that was referenced and code addressed which referenced memory. The technical parameters are:

• a memory location that was referenced
• IRQL at time of reference
• 0 = read, 1 = write
• code addressed which referenced memory

As mentioned earlier, if you are an end-user, there is nothing much that you can do to resolve this problem, but worry not for there are still possible solutions that could help you in fixing it. Refer to the suggestions laid out below to fix Bugcode 0xA –IRQL_NOT_LESS_OR_EQUAL error.

Option 1 – Try running the Hardware and Devices Troubleshooter

The first thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem. To use it, refer to these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 2 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Run the Memory Diagnostic Tool to check for Memory leaks

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select the option, your PC will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Error 0xc0000225 is the error that occurs on system startup, most times error just disappears all by itself but in some cases, it can be really persistent and can even cause you not to be able to enter the system that could be a really annoying thing, especially if there is some important task waiting to be finished. In this guide, we will present you with solutions for this error and how to solve it so you can get back to work as soon as possible.

Solution if you can not log into windows due to repeating error

If an error repeats itself constantly and you are unable to boot into Windows itself you will need to prepare Windows boot USB. You can download the Microsoft media creation tool here and then use it to create a bootable USB with Windows 10. Once the USB is done reboot your system and boot from USB. CHoose repair Windows instead of install and follow onscreen instructions.

Solution if you can log into Windows

If you can log into Windows bring up the command prompt in administrator mode and type in it SFC /SCANNOW followed by ENTER, wait for the whole operation to finish, and then reboot the system.

If you were trying to copy, move modify or delete a folder or a file in your computer but you’re not able to do so and encountered an error instead that says, “Could not find this item, This is no longer located in <path>, Verify the item’s location and try again”, then you’ve come to the right place as this post will guide you on how you can fix this error. You can encounter this error when you delete, rename, open or copy a certain file which is often created by third-party software and lacks important information like file format, and so on. Although you can see these files in File Explorer, you might not be able to perform some operations in them. To fix this problem, you need to check out the given suggestions below.

Option 1 – Try to rename the file via Command Prompt

If you were trying to rename the file but unable to do so, you can achieve that by executing a command in Command Prompt. Make sure to follow the steps carefully.

• Type in “Command Prompt” In the Start menu to search for it or you could also click the search button right next to the Start menu and then right-click on the related result and select the option “Run as administrator” to open Command Prompt with admin privileges.
• Next, type in “cd” followed by the path where the file is located with this format – “C:/Folder1/Folder2/Folder3”. However, you have to omit the problematic file this time. To put it simply, the last folder in the command must be the folder where the file is located.
• After inputting the command, press Enter on your keyboard and then use the set of commands given below. Note that each command is a new line so you need to tap Enter after copying each line.
  • DIR /A /X /P
  • RENAME (the current name of the problematic file) (a non-problematic name)
  • EXIT

Note: Make sure that you only input the current name and the new name separated by a space. You must not write the brackets in the command. If everything goes well, you will now be able to operate the file like you used to before.

Option 2 – Try to delete the file using Command Prompt

On the other hand, if you were trying to delete the file instead of renaming it, you can execute another command in Command Prompt.

• Open Command Prompt with admin privileges like what you did earlier.
• Once you’ve opened Command Prompt, copy and paste the command given below and tap Entre after you do so. You also have to make sure that you key in the correct path where the file is located as well as its name.

rd /s \?X:badfolderpath

Note: In the command above, “X” is the placeholder letter so you must input the letter that corresponds to the drive’s letter where the file is located.

• After that, you will see the “Operation completed successfully” message on your screen. If you don’t, check if you’ve really inputted the correct location of the file or its name.

Option 3 – Delete the file without any extension

If the file you were trying to delete does not have an extension, this means that Windows does not know what to do with this file which is why it’s throwing an error message. The best thing to do in such cases is to delete the file especially if it takes up a lot of memory. To delete these kinds of files, here’s what you have to do:

• Follow the first two steps from the previous option above so you can navigate to the location of the file accurately just be careful in inputting the folders.
• Don’t forget to tap Enter right after each command and then use the next command below so you can delete the affected file which has no extension:

del *.*

• After you’re done, open the File Explorer and then check if the file is now deleted or not.

Windows 10 has a lot of several useful features and one of them is the Nearby Sharing feature. You can access this feature by going to Start > Settings > System > Shared experiences. From there, switch on the Nearby Sharing option and select the folder where you want to download the files to. This feature is really useful as it allows you to share files. However, there were reports from a number of users recently stating that Nearby Sharing is not working on their Windows 10 computers. If you are one of the users facing this problem, you might want to try checking if the Windows 10 v1803 Update is installed on your computer or not. You could also try to check if Bluetooth supports low energy mode or you could also try bringing the device closer or check if the adapter has Bluetooth version 4.0 or later. For more information, refer to each one of the given options below.

Option 1 – Try checking if Windows 10 v1803 Update is installed

To check if the Windows 10 v1803 Update is installed on your computer, go to Start > Settings > System > About. From there, scroll down to the Windows specifications and check the Version. If it is 1803 or above, then the Nearby Sharing feature should be active on your computer. However, if you find that Windows 10 v1803 Update is not installed yet, then you need to update your computer to its latest version and then see if it fixes the problem or not.

Option 2 – Verify if Bluetooth supports low energy mode

Although low energy mode is not really necessary in using Nearby Sharing, there are some Bluetooth terminals that support low energy mode which makes a lot of difference. Thus, you need to check if Bluetooth in your computer supports low energy mode by following these steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After that, expand the list of Bluetooth adapters, and then right-click on your adapter and select Properties.
• Go to the Details tab and select Bluetooth radio supports Low Energy Central Role from the drop-down menu and if its value says “<true>”, it means that your Bluetooth supports low energy mode, otherwise, it doesn’t.
• If your Bluetooth does not support low energy mode, then you might want to consider purchasing an external one.

Option 3 – Try bringing the devices closer

Nearby Sharing might not work if your devices are not close enough. Thus, you need to bring your devices closer together and see if it fixes the problem. And when you do, make sure that Network Sharing is switched on for all the concerned devices.

Option 4 – Make sure that you’re using Bluetooth version 4.0 or later

For you to use the Nearby Sharing feature, you have to make sure that the adapter for all the concerned devices is using Bluetooth version 4.0 or later. So if one of the devices or if all the devices are not using this version or later versions, then you must buy an external Bluetooth adapter for you to enjoy the Nearby Sharing feature.

Hello everyone and welcome to how to fix Windows when it is not starting tutorial. Here we will tackle some common problems and solutions in order to help you to get back both your computer and Windows in working order. Windows not booting and loading is an annoying issue that can even result in complete loss of your data and can also consume a lot of time if no other solution than clean install remains. Also if you are not tech-savvy, this issue can cost you as well since you will have to hire a professional to solve this problem for you. Here at Error Tools, we aim to help so you can overcome your PC issues yourself by providing you daily with tutorials, tips, and tricks and helping you with all of your Windows issues. All of that being said, let's see what are issues that can prevent your computer or Windows from booting up and get around them so everything is back in working order.

1. Use repair tool

   Windows 10 comes with a startup repair tool that has the goal to repair and fix errors preventing Windows from booting up. To use this tool however you will need Windows 10 bootable USB stick. You can create a bootable USB directly on the Microsoft site. Once you have it ready, plug it in and reboot your computer, choose to boot from USB. When you are on the Windows setup screen, click on next and then on Repair your computer. Go to troubleshoot > Advanced options > Startup repair. When Startup repair is clicked, Windows will boot, scan files for issues, and if they are found he will automatically fix them.

2. “Windows Failed to Start” 0xc00000f error

   If you get this error on your boot of Windows, then you have corrupted boot configuration data. In order to fix this error, you will also need a bootable USB with Windows 10 on it. Make one on the Microsoft site if you don't have it and reboot your computer, boot from USB, on the setup screen click on next and then on Repair your computer. Click on Troubleshoot and then on the command prompt. In the command prompt type the following: bootrec /FixMbr bootrec /FixBoot bootrec /ScanOs bootrec /RebuildBcd exit Reboot your PC without a USB

3. Boot into safe mode

   Safe mode for Windows loads only its core without drivers and with minimal services. If you can boot into safe mode then the issue is with some application or driver causing the problem. Try the selective boot option to eliminate what is causing the error.

4. Make sure your hardware is connected

   Some RAM or hard drive out of socket can cause Windows not to be able to boot, check all connections just in case.

If everything else fails, perform a clean Windows installation. The reason for Windows not booting up can be caused by various viruses and malware also if that case it would be best to format and perform a clean install.

Error Code 0xC1900101, 0x30018? - What is it?

Users, when upgrading to Windows 10 from Windows 7 or Windows 8/8.1, or when upgrading to a new version, build, service pack, or major update of Windows 10, can encounter error code 0xC1900101, 0x30018. Windows 10 installation fails and stops or hangs. During the installation process, it will reach a certain maximum limit (normally at 6% or 32%) then reverts back to the previous version of the operating system and displays the following message:

0xC1900101 – 0x30018 The installation failed in the FIRST_BOOT phase with the error during the SYSPREP operation.

Solution

Error Causes

In attempting to fix Error Code 0xC1900101-0x30018, it is vital to know what causes this issue. The most probable causes of this error are:

• Incompatible hardware or driver
• Incompatible security programs or antivirus or incompatible utility software
• A device driver possibly stopped responding to setup.exe while on the installation process.

In some cases, you might be opened to other error messages when attempting to update to Windows 10, including error code 8007002c.

Further Information and Manual Repair

In fixing issues related to error codes, it is best to employ manual repair methods. Using these methods helps users pinpoint the root causes of the issue and apply solutions permanently to fix the issues. While most manual repair methods can be done by every Windows user, even those without technical abilities, there are certain cases where help from a Windows professional is needed. If you’re not up to facing risks in implementing manual methods yourself, consider getting help from a professional Windows technician or you can use a powerful automated tool. In fixing Error Code 0xC1900101-0x30018, you can repeat the same steps used for 0xc000021a (Method One) or you can try doing the following:
