How to Fix Error 421

Windows 11 has been rolling out for a while now so many PC users ask the question is it wise and good to upgrade your Operating System to the latest Microsoft incarnation. No Thank you for reading, cya tomorrow in next article. Jokes aside, I truly believe that choosing to upgrade your System to Windows 11 at this point in time is a bad decision and I will explain why I do believe it.

Reasons to upgrade to the new OS

First of all, let me say what is good in Windows 11 and provide reasons why you should upgrade your computer.

1. The new fancy look made for modern computers. New Windows new look, Microsoft has tried their best to bring a new modern look to its flagship operating system and I must say that they have managed it. I could argue that it is a little bit late since Apple had this kind of look in years but hey, better late than never I guess.
2. Increased security This point is very valid but it will play a role only if you have all system requirements including TPM 2.0. If that is the case new security features of OS are really well done and are perhaps one thing that might nudge some people in installing W11 on their system.
3. New settings app The New and redesigned settings app inside Windows 11 is really great and it provides a great workflow and easy management of system settings. This is not some radical change but it will save time and make life much easier.
4. It is better suited to the newest hardware Windows 11 was made with the newest hardware in mind and its performances on it are great so if you are punching the latest tech this reason is sufficient to make a switch, however, if you are still on an older system you will not gain much by switching.

Reasons to avoid Windows 11 for now

1. Almost just a visual update to Windows 10 Some features of Windows 11 are great but they are not plenty of them to justify a new number and new version of OS. Considering what we really got new under the hood Windows 11 could have been just a patch and update to Windows 10 since the architecture is the same.
2. Bugs Each day there are new bugs reporting for Windows 11, most of them are at the moment unsolvable and are caused because hardware manufacturers' drivers and software overall is not W11 ready. This hinders the stability of some systems and introduces headaches to others.
3. Runs poorly on unsupported hardware Strange behavior has been reported on some older systems, granted systems are not officially supported but the point is OS is simply not working at the top of its game on older hardware.
4. No updates on non supported systems Officially stated if you install Windows 11 on non-supported hardware you will not get any security updated on in. This is a deal-breaker as far as I am concerned.
5. It is still under development When Windows 11 was released, Android native apps were not working on it, it later came with an update, this is just one example but there are more features that were promised but are not delivered on release and constant updates are fixing these things. It is obvious that Windows 11 is still under active development and not the final product that was promised.
6. Microsoft’s edge pushing And not just edge, some other things as well but most notably is edge pushing to borders they are risking lawsuit similar as they did in the past pushing and disabling any other browser except internet explorer.

Conclusion

Firstly I want to point that this is my personal opinion but going through facts and taking into account the current state of Windows 11, at this point, it is not worth making a switch. I am sure that in time it will become a system that will be worth upgrading to but until that time comes, my advice would be to stay with Windows 10.

Google's Pixel smartphone is one if not the best Android smartphone on the market. It regularly gets updates and Google is really trying to keep it as a top choice for Android smartphone users. One of the new things that Google has released for its smartphone series is a new emergency dialer.

With an emergency dialer, you will be able to quickly access local contact information for police, fire, and medical services. This dialer is able to contact before mentioned services even when the phone is locked and when you are traveling.

The idea is to quickly access the default emergency number no matter in which country you are currently in, service will find the appropriate number and set it as default so if you need it there is no delay in searching for the appropriate number and dialing it.

Once the service is enabled on the device you can swipe up and tap Emergency call without unlocking your phone or you can press and hold the power button for five seconds and tap Emergency.

If you have a Pixel smartphone go to the Google support page and follow instructions on how to enable this service. It costs nothing and it could potentially even save your life.

Caching is used to enhance the performance of applications in Windows and other operating systems. It helps applications to load faster but there are times when the cache can get damaged or corrupted and as a result, you might encounter some issues. One of them is in the Firefox browser where the “Your Firefox profile cannot be loaded, It may be missing or inaccessible” error message may appear. You could also encounter this kind of error when Firefox is unable to access or find the profile folder. In case you don’t know what the profile folder is, it is where Firefox stores your user data and settings by default. Firefox pulls information from this folder each time you choose to open it. You can find this default Firefox profile folder under the %APPDATA%MozillaFirefoxProfiles folder. If you experience issues when trying to access the Profile Manager, you have the option to create a new default Firefox profile folder. This will fix the “Your Firefox profile cannot be loaded, It may be missing or inaccessible” error. How? Simply follow the given steps below. Step 1: Tap the Win key or click the Windows Start button to open the Start menu. Step 2: Next, type “%appdata%” in the field and hit Enter to open the hidden AppDataRoaming folder. Step 3: Now double click the Mozilla folder as well as the Firefox folder. Step 4: From there, look for the “profiles.ini” file and delete it. Make sure that you don’t delete the Profiles folder which should have the icon of a file folder. Note: Keep in mind that the .ini file extension is identified as the file that features a gear icon beside the “Configuration settings” or “Application settings”. Step 5: Once you open Firefox, a new profile will be created. On the other hand, if you know where your profile exists, you can try the following steps below to help Firefox locate it.

• First, you need to move the profile folder back to its original location.
• Next, restore the profile folder’s original name if you have modified it.
• Then create a new profile using the Profile Manager and give it an appropriate name.
• Now click on the Choose Folder button and select the profile folder you have moved or renamed before you exit the Create a new profile wizard.

Each you connect time external devices like scanners, printers, and the likes to a Windows 10 computer, the device either pushes the drivers through the USB or any other port, or you are expected to install the drivers through external media. In both cases, the driver will be loaded into the system, allowing you to use the device. However, it doesn’t always go smoothly as you could encounter some errors like the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory ( Code 38 )”. If you encounter such an error in the Device Manager, then this means that a previous version of the device driver is still in memory and that each time the device is used, that previous version is loaded into memory and then unloaded which triggers the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory (Code 38)” error. This kind of error occurs if the operating system loads the unwanted driver or if it fails to unload the driver. It could be that there is an obsolete version of the driver that’s still installed in the system or it could also be that you need to update your USB drivers as they could be outdated or the problem could also be due to some third party program that is interfering with the installation. Whatever the cause is, here are some suggestions you can check out to resolve the problem.

Option 1 – Uninstall previously installed drivers and reinstall their latest working version from the manufacturer’s website

The first thing you can do is to uninstall the drivers that are currently installed on your computer and then reinstall their latest working versions from their official sites. This kind of error is commonly encountered while loading drivers for scanners and printers. This is due to the fact that their drivers and software come along with a package which is usually in external media like CD or DVD. So when you install the software package, there’s a possibility that a newer version has been launched by its manufacturer. When that happens, you have to uninstall the previously installed driver package and then download the drivers from the manufacturer’s website and install them.

Option 2 – Run the Hardware and Devices Troubleshooter

• 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 3 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 4 – Restart your computer in a Clean Boot State

If the first three given options didn’t work and you still see the error when you connect external devices, you can try putting your computer in a Clean Boot State and then try connecting them again.

• 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.)
• Now try to connect the external devices and check if the error is now gone.

If you are browsing the web but suddenly encountered the ERR_BLOCKED_BY_CLIENT error on your Chrome browser in Windows 10, read on as this post will guide you in fixing this problem. This kind of error has already been reported by a number of Chrome users and it seems that the problem has something to do with a plugin or extension. Here’s the exact content of the error:

“This webpage was blocked by an extension (ERR_BLOCKED_BY_CLIENT)”

This kind of error, as pointed out, could be caused by an extension or plugin on Chrome that is blocking the web page. It is also possible that the version of Chrome is obsolete or that there could be more than 100 bookmarks in the Bookmark Manager. Before you troubleshoot the problem, make sure that you download the latest version of Google Chrome and see if it fixes the error. If it didn’t, then you can try opening a web page in Incognito Mode or disable and remove the extension that’s causing the problem. You could also try to remove any surplus bookmarks.

Option 1 – Try to open the web page in Incognito Mode

The first thing you can do to fix the problem is to try opening the web page in Incognito Mode. When your browser is in this mode, it will work without extensions. This would help in fixing the problem especially if it was caused by some extension or toolbar in your browser. All you have to do is open any web page in Chrome and tap the Ctrl + Shift + N key combination to open a window in Incognito Mode.

Option 2 – Try to disable and get rid of the problematic extension

After you’ve isolated the problem and have determined that an extension is the one that’s causing it, then the next thing you have to do is to disable or get rid of that extension.

• 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.
• After clicking the Advanced option, go to the “Restore and clean up option and click on the “Restore settings to their original defaults” option to reset Google Chrome.
• Now restart Google Chrome.

Option 3 – Try removing surplus bookmarks

If your Chrome browser is already supporting more than 100 bookmarks, you might want to consider deleting them as it could also be one of the reasons why you’re getting the ERR_BLOCKED_BY_CLIENT error. To remove these bookmarks, just open the bookmark library by typing this address “chrome://bookmarks/” in the address bar of Chrome and tap Enter and press Shift and then select the surplus bookmarks by using the arrow keys. After that, click Delete to get rid of them.

Option 4 – Try clearing browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BLOCKED_BY_CLIENT. 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.

Both the DISKPART utility and the Disk Management are useful tools in Windows 10 that manage the disk space allocation, and so on. But these tools are not without errors as you could also encounter some when you run them. Recently, some users reported getting an error that says, “The selected disk is not a fixed MBR disk when trying to use the DISKPART utility”. Here’s the exact message of the error:

“The selected disk is not a fixed MBR disk. The ACTIVE command can only be used on fixed MBR disks.”

This kind of error only occurs when you try to activate a disk partition on a UEFI system partition. However, the command works only if your computer is based on BIOS/MBR. The UEFI method has no concept of the active partition and since you have a UEFI system, the disk type is GPT instead of MBR. To simply put it, your BIOS needs the MBR disk type while the UEFI needs the GPT disk type. To fix the “The selected disk is not a fixed MBR disk when trying to use the DISKPART utility” error, there are various potential fixes you can try. You might have to disable Secure Boot, convert the disk to MBR or fix the Boot Manager. For more instructions, follow the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try converting the disk to MBR

You can try to change the File System of the drive from GPT to MBR but before you do so, make sure that you create a backup copy of your data to an external drive. Once you have that covered, follow the steps below.

• Create a bootable Windows 10 media and boot your computer from it.
• Next, click on the “Repair your computer” option on the first Windows 10 installation setup window.
• Afterward, select the operating system partition from the given options and click on Next.
• Now select Command Prompt within the System Recovery options box and execute this command to initiate the Diskpart utility: diskpart
• Then type either one of these commands to view the list of all the Disk connects or the partitions on those disks formed: list disk or list volume
• After that, execute another one of these commands depending on the command you previously entered to select the disk or partition you want to select: select disk # or select volume #
• Now execute this command to clean your drive: clean
• Finally, execute this last command to convert the selected disk or partition as MBR: Convert MBR
• Restart your computer and check if the error is fixed.

Option 3 – Try to fix the Boot Manager

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
  • bootrec /FixMbr
  • bootrec /FixBoot
  • bootrec /RebuildBcd
• Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed error code 0xc000014c.

If you connected headphones to your Windows 10 computer to listen to audio but when you check it in the playback devices, you’re not able to find it, read on as this post will guide you in what you can do to figure out what exactly caused this kind of problem and how you can resolve it. This kind of issue could simply be with the headphone itself or the headphone port or your operating system. So if it turns out that the problem is with the hardware, you might have to replace the components. However, it is recommended that you troubleshoot the problem first before doing that. The most basic thing you can do is to try changing the headphone port, although this can be quite difficult since most computers don’t have any extra port for headphones if your computer has one, then give it a go. If it still didn’t work, follow each one of the options provided below.

Option 1 – Try to run the Playing Audio troubleshooter

Since the Windows 10 operating system has the Playing Audio Troubleshooter, you can use this troubleshooter to try and fix the problem with the “No Audio Output Device is installed” error. You can access this tool in the Control Panel or in the Taskbar Search and even on the Troubleshooters page of Windows 10. Run this troubleshooter and see if it can fix the issue or not.

Option 2 – Try to update the Audio driver

If the error has something to do with software, chances are it might be related to the audio driver – it could be that the newest version of your Windows 10 does not work well with the old version of the driver. This is why you have to update your audio driver to the newest available version.

• Tap the Win + R keys to open the Run dialog box and then type in MSC and tap Enter or click OK to open the Device Manager.
• Expand the section of the Audio inputs and outputs.
• And then from the drop-down menu, select the Update Driver option and follow the on-screen instructions to install the latest version of the driver.
• Then also click on the option, “Search automatically for updated driver software.
• Restart your PC after the installation.

Note: If updating the Audio driver didn’t work, you can go to the website of your PC manufacturer and look for the support section where you can download the drivers for your computer. You just need to take note of your PC’s correct model and model number so you can find the appropriate driver.

Option 3 – Try enabling the headphones from the playback devices

• Tap the Win + R keys to open the Run dialog box and type the “CPL” command.
• Tap Enter to open the Playback devices.
• Next, right-click on any open space section and check the boxes for the “Show Disconnected Devices” and “Show Disabled Devices” options.
• After that, this should help in displaying the headphones in the section of Playback devices.
• And if they are disabled, you can just right-click them to have them enabled.

On September 18th, 2017, Cisco’s Talos announced that CCleaner, a popular utility with billions of worldwide users, had been compromised by hackers, and was used to unwittingly distribute hidden malware in its installer. Later in the day, Piriform, the publisher of CCleaner, confirmed the problem.

Undetected by all but 1 major antivirus including CCleaner’s own parent company, this occurred for over a month and impacted over 2.7 million users. Users of CCleaner v5.33.6162 and CCleaner Cloud v1.07.3191 for 32-bit Windows are affected. These downloads were live on CCleaner’s official site from August 15th to September 12th, 2017. Anyone who downloaded the program during this time could be affected. The company claims that while the hackers set up the backdoor and many users were impacted, that the perpetrators have been arrested and that the malware never successfully performed its full task and compromised user’s PCs or sent out their data; in the wake of recent security breaches such as Equifax, users are understandably worried. Given the severity of the threat of hacking and data theft, users should take action immediately if they have CCleaner.

Technical Details of CCleaner Malware Injection

First reported by Talos, the malware, which was hidden in the CCleaner installer without the publisher noticing (despite them being owned by Avast, a massive Anti-virus company), modified a core program DLL file to evade detection, and creates several registry keys. Not only were these files not flagged by any major Anti-Virus, but they were also even digitally signed by Piriform via their Symantec certificate, meaning your PC and security program would likely whitelist and trust the malicious installer. The malware gathers personal information on a user’s PC, including IP address and running programs, and sends it to a remote server. In our testing, the program sent data to IP 216.126.225.148.

Restore Your PC (If Possible)

As of the publication of this article, there have been no assurances given that updating or even uninstalling CCleaner will remove the malware is installed. The only action thus far has been shutting down the remote server where user data was being sent has been shut down by authorities. For this reason, it is best to remove the underlying malware separately, as its presence represents a serious security threat. Unfortunately, as this could have been installed as far back as August 15th, 2017, your System Restore points may not go back that far, or even if they do, restoring to such an outdated point may cause unintended problems with other programs you use and potentially lost files and data. Manually backing up files and doing a full format or clean Windows installation would likely be successful in fully removing the malware, but is extremely time-consuming and can be difficult for many PC users. Unfortunately, this makes a PC Restore or format an unattainable option for many.

Update CCleaner to the Latest Version

While CCleaner has told users to update to the latest version of the program. Prior to doing so, we recommend fully uninstall CCleaner, ensuring you check its program files folders and registry keys, manually deleting any remnants, and then re-downloading the latest version from the official site and reinstalling clean.
