The task image is corrupt/tampered 0x80041321

If you are trying to connect your mobile or external device to your Windows 10 computer but suddenly encountered an error saying, “A device attached to the system is not functioning”, read on as this post will guide you on how you can resolve this error using a couple of potential fixes. In this case, it is possible that the connected device is not working for some reason and this error pops up when you connect your device or when you try to move or copy files from your computer to your external device and vice versa. As you can see, the error message is pretty straightforward, and it mostly occurs when you connect plug and play devices such as USB drives, printers, external storage devices, and many more. And when you open the Device Manager to check the device, you will most likely see a yellow exclamation mark on the device which indicates that the device is currently having problems. To fix this problem, there are several options you can check out. You need to check the status of the device or check the compatibility between the external device and the drive types. You also have to make sure that the device is connected properly or check if the device has been formatted properly. For more details, follow the given suggestions below.

Option 1 – Try to check the status of the device

The first thing you can do to get rid of the error is to check the status of the external device, especially if it’s a plug-and-play device. So when your computer boots, check if it is able to detect the device or not.

Option 2 – Try to check the compatibility between the external devices and drivers

As you know, when you connect an external device to your computer, Windows installs drivers to communicate with the device, the same way as any hardware you connect to the motherboard and if the driver ends up getting corrupted or is incompatible, then you need to update the device driver. To do that, follow the steps below.

• 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 driver the external device related to and then right-click on each one of the Device drivers and select the Update Driver from the menu.
• Restart your PC and then click the “Search automatically for updated driver software” option.

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

Option 3 – Try checking the hardware connections

The first thing you have to do before you further troubleshoot the problem is to check the hardware connections of your computer and see if there are damaged ones, just like with USB ports, it would also affect the overall connectivity of the device with the computer. So if you notice some irregularities in the connecting cable physically, you might have to buy another one and replace it and then see if it fixes the problem or not.

Option 4 – Check if the device is formatted properly

You might also want to check if the external device is properly formatted especially if you’ve recently formatted it. If a device wasn’t formatted properly, then it’s no wonder why you’re getting the “A device attached to the system is not functioning” error. To fix this, you need to use Disk Management. From there, you can find the devices connected but are not visible. If you are using an admin account, then to fix this error, you have the option to format the drive or create new partitions using the interface. Once you do this, it should resolve the problem.

Option 5 – Try to run System File Checker or SFC scan

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.
• Once done, restart your computer.

Option 6 – Restart your computer in a Clean Boot State

If a third party program like antivirus is the one that’s causing the problem, you can try to put your computer in a Clean Boot State to isolate the issue by following these steps:

• 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 your device or copy the files to your external device again and check if the error is now gone.

Error Code 0xc004fc03 – What is it?

Error code 0xc004fc03 occurs when Windows users fail to activate their Windows operating system due to a networking problem. The error code’s common symptoms include the following:

• Inability to activate Windows 10 operating system
• Message box with error code 0xc004fc03

Solution

Error Causes

Error code 0xc004fc03 in Windows 10 usually occurs due to issues related to a Windows user’s network. Your computer may be having problems connecting to the Internet or your firewall may be blocking or interrupting your device’s ability to activate Windows 10. In some cases, users may simply need to wait a day or two to reattempt to activate their system using a valid product key, as there may be an issue with the Windows activation servers.  Failure to promptly fix this error code might result in other Windows 10 error messages, such as error code 0xc004f034.

Further Information and Manual Repair

To rectify the error code, Windows 10 users will need to perform manual repair procedures that fix the underlying problems causing error code 0xc004fc03. These procedures may include reconnecting to one’s network, checking your firewall settings, or activating your Windows operating system via phone. The manual repair methods are simple and do not require technical knowledge of the Windows operating system. If your attempts at manually repairing this error code fail, however, you may need to try a few other procedures.

Method One: Verify Internet Connection

To check your Internet connection, you’ll need to access the Network & Internet tab in Windows 10. Follow the instructions below to access this tab and fix Internet connectivity issues if they are preventing you from activating Windows on your machine.

• Step one: Click the Start button and select Settings
• Step two: Select Network & Internet
• Step three: Click the Status section of the Network & Internet tab

If your status shows that you are not connected to a network, you will need to fix your connection. Simply use the Network Troubleshooter to troubleshoot your connection. You will be able to activate your copy of Windows once your connectivity issues are resolved.

If, however, the problem persists and error code 0xc004fc03 occurs during the activation process, this simply means that the existence of the error code is not due to connectivity or networking problems. In such a case, move to the next manual repair method listed below and follow the exact instructions given.

Method Two: Check Firewall Settings

Windows Firewall protects your PC from hackers, worms, and other malicious programs. However, in some cases, it may result in error codes like error code 0xc004fc03. If your firewall is interfering with the Windows 10 activation, you’ll be able to rectify the problem by simply adjusting your settings. Follow the steps below to check – and adjust if necessary – your Windows Firewall settings.

• Step one: Click search bar and type firewall
• Step two: Select Windows Firewall
• Step three: Select Turn Windows Firewall on or off

In some cases, Windows users may not be able to adjust settings within the Windows Firewall tab, as your firewall settings may be controlled by a third party antivirus software. If this is the case, open the antivirus software and turn off the firewall if the software does not prevent you from making such changes to its settings.

Note, however, that you will need to readjust the settings as soon as you activate your version of Windows 10. This is due to the fact that turning off your firewall settings permanently may lead to exposure to worms and other malicious programs.

Method Three: Activate Windows by Phone

Activation of Windows via phone is another option for individuals experiencing error code 0xc004fc03. The activate by phone option in the Update & Security tab will be available once you fail to activate Windows 10. To complete this manual repair method, follow the steps below.

• Step one: Select Settings
• Step two: Click Update & security
• Step three: Select Activate by phone
• Step four: Follow the instructions provided thereafter.

This is one of the most effective ways to fix error code 0xc004fc03. If the issue persists, however, you can proceed to the last resort.

Method Four: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

Error Code 0x80070490 - What is it?

When downloading a Windows update, it is important to remember that these updates are what keeps your computer safe. Some users have reported seeing error code 0x80070490 when allowing updates for their Windows PC. This error code may appear when the user is trying to connect to the update site for Windows and maybe a result of a corrupted CBS manifest. Having this error code will not only stop the update of the system, but it will also certainly halt any work being done with the computer. Quite a few Windows users have written in complaints about this error while updating from any prior Windows update to Windows 10.

Common symptoms include:

• While a user is performing the updates, the Windows computer will stop running the updates, and it will show the error code 0x80070490.
• Windows updates will not install any new features and will not install security patches.
• The computer will not continue with the Windows update, and it may revert back to the previous state that the computer was in, prior to attempting the updates.

Error Causes

There is not a lot known about what exactly causes the error code 0x80070490, but it is something critical that makes Windows abruptly stop its updates. It could be caused by a simple glitch in the computer system, or it could be caused by a larger problem. One thought is that the CBS (Component-Based Servicing) manifest can be corrupt. Another thought is that the computer's anti-virus software may be interfering with the computer's ability to perform the necessary updates.

Further Information and Manual Repair

There is very little information known about error code 0x80070490 and why it exists, but there are a few methods in which to correct it. Users should be careful when trying to fix this error themselves. If the user feels that the methods are too complicated or they are uncomfortable taking it on themselves, they should contact a Windows repair technician to fix the problem. Not all methods listed will suit the user's needs, but it is dependent upon the problem at hand as to which method will be the best fit to fix the error code. If these steps are taken and the error is not corrected, it is vital to contact the Windows repair technician.

Method One: Creating a new local account

Create a new local account on the computer, and allow administrator privileges on it. Next, move all of your documents and personal files to the new account. Delete the old account (you will no longer be using this) and switch over to the new one. After switching to the new local account, add the Microsoft account to it.

Method Two: Delete user ID, Store cache from the registry

• You will need to open the Registry Editor. Do this by pressing the Windows Key and R, then typing in “Regedit”. After this is typed in, press Enter or click the OK button to start the registry editor.
• When this starts, you will need to navigate all the way to the following key on the left pane:
• HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionAppxAppxAllUserStore After this, find the key that is similar to this: S-1-5-21-1505978256-3813739684-4272618129-1016
• NOTE: this is just an example. The keys will be in a similar format but will not look exactly like this.
• Select all the keys that look like this, and then delete them. After these keys are deleted, close the Registry Editor and restart the computer.

Method Three: Check to see if BITS, MSI Installer, Cryptographic, and Windows Update Services are running

Press the Windows key and R. Then, type in services.msc. After the Services window starts up, find the following services:  BITS, MSI Installer, Cryptographic, and Windows Update Services. When these services are found, make sure that they are up and running. If one or more of these services is not running, make sure that they are started. To do this, select the service and then click on Start the Service.

Method Four: Windows Update Troubleshooting

Press the Windows key plus W and then type in “troubleshooting”.  Select Troubleshooting. On the top left corner, select View All. Click on Windows Update troubleshooter. After this, follow the on-screen instructions in order to run the troubleshooter. After the troubleshooter has run, the issue should be fixed.

As you know, the Win + X menu, which is the shortcut context menu, is a useful way to launch several utilizes in Windows such as Power Options, Windows PowerShell, Event Viewer, Device Manager, and so on. However, there are times when you might experience difficulty in identifying the required utility. This is actually a part of the Windows 10 shell that goes out of scope in the customization of Windows 10. However, there is an easy trick you can use to do that. So in this post, you will be guided on how you can rename the options in the Win + X menu in Windows 10. In case you don’t know, the context menu is divided into three groups. Microsoft has categorized the bottom-most part as Group 1, while the middle part is categorized as Group 2 and the first part as Group 3. To rename these options, you need to use File Explorer and follow the instructions laid out below. Step 1: First, tap the Win + E keys to open File Explorer. Step 2: Next, navigate to this path: %LocalAppdata%MicrosoftWindowsWinX Step 3: From there, you should see three folders as Group 1, Group 2, and Group 3. Open the appropriate folder of your choice. Step 4: After that, right-click on the shortcut option you want to rename and then select Properties. Step 5: Next, navigate to the Shortcut tab under the Properties window. Step 6: Now in the text field of Comment, enter the new name of the option you selected. Step 7: Click on the Apply and OK buttons to save the changes made. Note: You can now either Sign back in or sign out of your Windows 10 User Account to see the result of the changes you’ve made. You could also restart the process of File Explorer via Task Manager. This will close the File Explorer as well as the shell components and then only launch the shell components again. In addition, you can check the Win + X menu to see the customized name that you’ve just set for a particular option. As you can see, even though it does not add anything extra, it is still a lot better in knowing how you can customize it.

SmartScreen is a cloud-based anti-phishing and anti-malware component that’s come packed in all Windows 8 (8.1) and Windows 10 versions. This security component is also used in several browsers and programs like Internet Explorer, Microsoft Edge and Outlook.com. Although this program is quite useful, there’ve been reports that SmartScreen is apparently blocking Microsoft’s own apps from opening. According to some users, they only get the “Windows SmartScreen can’t be reached right now” error message every time they try to open apps from the built-in Windows suite like Photos, Mail, Alarms, Maps, etc. Whenever Windows SmartScreen is either down or unreachable on an end-user PC, your computer won’t be able to download anything in both official and unofficial channels. This error might be due to a corrupted Windows account, or it could be that SmartScreen is disabled from the Windows Defender Security Center or it might be down due to an MS issue. In addition, the error might also be caused by a proxy entry.

Option 1 – Make sure that SmartScreen is enabled

Before anything else, the first thing you must do is to check if SmartScreen is even enabled as it might be the reason why you’re getting the error. You can verify this by simply going to the Windows Defender Security Center. To do so, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “ms-settings:windowsdefender” in the field and hit Enter to open the Windows Defender Security Center.
• After that, click on the Open Windows Defender Security Center button located under Windows Security.
• Then click on App & browser control.
• From there, make sure that the Check apps and files toggle is set to Warn and then check the same thing for Microsoft Edge and SmartScreen for Microsoft Store apps.
• If it turns out that SmartScreen is indeed disabled, you have to restart your computer after making some changes and then check if the issue is fixed upon the next startup.

Option 2 – Check if SmartScreen is down for maintenance

Another possible reason why SmartScreen is not working is that it might be scheduled for maintenance. When SmartScreen is scheduled for maintenance, it will become unreachable for a lot of users at the same time and so before you go over unnecessary troubleshooting steps, you need to verify if SmartScreen is down for maintenance or not.

Option 3 – Try to disable the proxy server

If applicable, you can try to disable the proxy server to fix SmartScreen. There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. In some instances, certain proxy servers can interfere with the SmartScreen component and cause it to become unusable. However, if you are not using a proxy server, just skip this option and proceed to the next one, otherwise, follow the steps below to disable the proxy server.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “ms-settings:network-proxy” in the field and hit Enter to open the Proxy tab under Settings.
• After that, scroll down to the Manual proxy setup and make sure that the toggle button of the “Use a proxy server” option is turned off.
• Now restart your PC and check if the problem is fixed upon the next startup.

Option 4 – Try to create a new Windows user account

There are some users who were able to fix the problem by simply creating a new Windows user account. Although this solution will make you lose a couple of settings enforced through your user account, it’s actually effective in circumventing the “Windows SmartScreen can’t be reached right now” error. To create a new Windows user account, here’s what you have to do:

• Tap the Win + R keys to open the Run dialog box.
• And then type “ms-settings:otherusers” in the field and hit Enter to open the Family & other people tab under the Accounts menu.
• After that, click on the “Add someone else to this PC” option and then click on “I don’t have this person’s sign-in information.
• Next, insert the user credentials like emails, password, birth date, etc., and then click Next. Take note that if you want to create a new local user account, just click on Add a user without a Microsoft account.
• After you’re done creating the new Windows user account, click the start icon and then click the account icon and choose to Sign out.
• After you’re logged in, check if SmartScreen now works properly or not.

When clean Windows is installed or when you place new hardware in your computer usually Windows itself detects the device and installs its driver. The question that comes now is, do you keep that driver or do you install the manufacturer's one. In order to answer this question let's analyze what is difference between the two drivers and other factors which could influence your decision.

Difference between drivers

First of all, know that drivers Windows installs are also drivers from the device manufacturer which have gone through Microsoft quality control in order to be included in Windows itself. Now naturally question which occurs, what is the difference, well answer to that would be this: in Windows, you have stripped down driver, just a driver in order for Windows to know what device is plugged and how to use it, meaning that for example if you install printer device, you will be able to print documents and Windows will know it is a printer but ... You will not get the control panel for that printer where you can adjust the printer itself and all of its features like let's say paperweight, etc. So if you need these kinds of features in that case it would be better to install a complete driver suite from the manufacturer and get the whole package. Windows will recognize the RAZER mouse for example but you will not be able to change its colors of program custom buttons on it until you install RAZER drivers. One more important thing to note is that drivers which are in Windows are less updated than drivers from the manufacturer's site. That being said, if you prefer and want to have the latest drivers you will prefer to get them again from the manufacturer.

Conclusion

So it seems that manufacturer's drivers are always in some form of advantage and that you will always want them and most of the time this is true, as a matter of fact, the only time I could think that you could use bare down Windows drivers is when new drivers update breaks something in Windows and device start behaving improperly. in this particular case, it is better to roll back to the previous Windows driver which has passed Microsoft quality control and is working for sure. In any other case, you are better off with the latest manufacturers drivers If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.

In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10. But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system. This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues. All of that being said, let's start.

Setting new font

First thing is to open notepad, in the notepad paste the next block of code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="" "Segoe UI Bold (TrueType)"="" "Segoe UI Bold Italic (TrueType)"="" "Segoe UI Italic (TrueType)"="" "Segoe UI Light (TrueType)"="" "Segoe UI Semibold (TrueType)"="" "Segoe UI Symbol (TrueType)"="" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"="NEW_FONT"

Where in "Segoe UI"="NEW_FONT" instead of NEW_FONT you need to write the exact name of the font that you wish to use as a system font. Once you have replaced the default system font with your desired one, go to File and save as, from file type drop-down menu, choose all files and save this file as .REG type giving it whatever name you wish. When the file is saved, close notepad, right-click on the saved file and choose the merge option. Confirm with YES and click on OK. Reboot your system and your Windows will now use the font of your choice as its default system font.

Restoring default font

If you wish to return the old default system font as it was, follow the same steps but in your notepad paste this code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="segoeui.ttf" "Segoe UI Black (TrueType)"="seguibl.ttf" "Segoe UI Black Italic (TrueType)"="seguibli.ttf" "Segoe UI Bold (TrueType)"="segoeuib.ttf" "Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf" "Segoe UI Emoji (TrueType)"="seguiemj.ttf" "Segoe UI Historic (TrueType)"="seguihis.ttf" "Segoe UI Italic (TrueType)"="segoeuii.ttf" "Segoe UI Light (TrueType)"="segoeuil.ttf" "Segoe UI Light Italic (TrueType)"="seguili.ttf" "Segoe UI Semibold (TrueType)"="seguisb.ttf" "Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf" "Segoe UI Semilight (TrueType)"="segoeuisl.ttf" "Segoe UI Semilight Italic (TrueType)"="seguisli.ttf" "Segoe UI Symbol (TrueType)"="seguisym.ttf" "Segoe MDL2 Assets (TrueType)"="segmdl2.ttf" "Segoe Print (TrueType)"="segoepr.ttf" "Segoe Print Bold (TrueType)"="segoeprb.ttf" "Segoe Script (TrueType)"="segoesc.ttf" "Segoe Script Bold (TrueType)"="segoescb.ttf" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"=-

Reboot your system and your Windows will now revert the font of your choice as its default system font.
