Fixing corrupted system files in Windows

Stop 0x0000000A - What is it?

Stop 0x000000A is a type of blue screen of death error associated with Windows XP. It occurs either during or after the installation of Windows XP. In other cases, the stop 0x000000A error may occur when the device driver uses an incorrect memory address, causing an IRQ conflict. The Stop 0x000000A error message means that a process or a driver attempted to access a memory section without permission.  The stop error message is displayed in the following format:

Stop: 0x0000000A (parameter1, parameter2, parameter3, parameter4) IRQL_NOT_LESS_OR_EQUAL *** Address x has base at x - filename

Solution

Error Causes

The stop 0x000000A error is triggered due to multiple reasons. These include:

• Faulty hardware
• The poor device driver installation
• Incompatible device driver
• Viruses and malware attack
• Disk fragmentation

Blue screen of death errors like the stop 0x000000A error code is critical. These errors may pose serious PC threats. When this error occurs the computer screen turns blue, the program running on the system stops and if the error is not fixed in time it may also result in a system crash and failure.

Further Information and Manual Repair

To resolve the Stop 0x000000A error on your PC, here are some solutions that you can try:

1. Roll Back Drivers

To do this, click on the start button and go to the control panel. Then double click the system icon and locate the ‘System Properties’ window. After that click on the ‘hardware’ tab and then click the ‘Device Manager’ button. Here locate the device that you recently updated which could be causing the IRQ conflict. Now double click the device recently updated and click the driver tab. Then click on the ‘Roll Back Driver' button. Wait for the process to finish and then simply reboot your system.

2. Specify the Hardware Abstraction Layer (HAL)

Another method to resolve the Stop 0x000000A error on your system is to specify the hardware abstraction layer (HAL). This can be done during Windows XP installation startup. Simply press the F5 button on your keyboard while the “Setup is inspecting your computer’s hardware configuration’. When prompted, make sure that you specify the correct computer type and HAL (the Hardware Abstraction Layer). Most computers use a single processor, if your computer also has a single processor then simply select ‘Standard PC HAL’ computer type from the menu. Now reboot your PC and then reinstall the Windows XP operating system. If the error is still not resolved then try turning off features in CMOS settings

3. Turn off Features in CMOS Settings

Turn off all the following features in the CMOS settings:

• All caching, including L2, BIOS, internal/external, and write back caching on disk controllers
• Plug and Play
• All shadowing
• Any BIOS-based virus protection feature

After turning off these features, try reinstalling Windows XP again. If this works, then that’s great! However, if it doesn’t, then try method 4; maybe the cause of the stop 0x000000A is associated with incompatible drivers.

4. Install Windows XP compatible Drivers

Sometimes device driver compatibility can also shoot up the stop 0x000000A error message. First, remove the drivers that are incompatible with Windows XP. Now obtain and install new Windows XP compatible drivers. To do this, go to the start menu and the control panel. Now double click on Add or Remove Programs icon. Select the drivers that are incompatible with Windows XP and click on the remove button. After that restart PC and install Windows XP, compatible drivers, for the hardware devices on your system.

5. Scan for Viruses and Repair the Registry

If all the methods discussed above do not resolve the stop 0x000000A error on your PC, then it means either your computer is affected by an infection virus or the problem is associated with the registry like disk fragmentation and invalid entries.

In case you didn’t know, the new Windows 10 v1903 has brought tons of new features around Windows 10 Updates. One of these features is the ability to automatically adjust the Active Hours based on your computer activity. This feature is really useful as it tells the operating system when to install the Windows Updates. A lot of users use the Active Hours feature to ensure that the Windows Update won’t force them to restart their PCs to install the update. So if your computer is turned on, it won’t apply the update during the active hours you’ve specified. In addition, the active hours change for many users and they are not that strict. For instance, if you set the active hours between 10 am to 5 pm, Windows Update won’t be forcing you to restart your computer to install the updates at those times. Note that Windows Update allows enabling an option using where it can monitor the active hours in your computer and change it. To configure this setting, here’s what you have to do:

• Frist, go to Settings > Update & security > Windows Update.
• Next, take note of your current active hours and click on the “Change active hours” link.
• Then toggle the option that says, “Automatically adjust active hours for this device based on activity”. This will change the active hours and if you match it with the previous one, it should be different.

As you can see on the image given above, the earlier active hours were between 8:00 to 17:00 and were changed to 11:00 to 19:00. If you have been using this feature for a while you’ll find how useful and handy it is especially when you’re using your computer and don’t want any notifications like the prompts for Windows Updates to bother you while working.

If you are trying to save a file in a PDF format on your Windows 10 computer but then the PDF text content in an Adobe file suddenly disappears, then read on. This post will give you more insight into this issue. This kind of issue is rare and mostly occurs in forms that you can fill upon. In such a case, the text you enter in the form vanishes right after you click the Save button. One of the benefits of working with PDF files is that it has the ability to compress high-quality files to relatively small file sizes. This is really useful especially when you are saving hard drive space and you’re working with limited storage resources. However, these files can contain layered content if they are created from layered documents using applications like Adobe InDesign. Consequently, a single page of the PDF file can contain different layers with different content. So if you try to save or print a PDF file that contains layered content, the elements will disappear from the PDF. To resolve this issue, you can try to merge or flatten the file since it will help keep the changes in the PDF file. On the other hand, you can no longer make any alterations or form data once you flatten the file. Another thing to keep in mind is that merging or flattening the file can’t be undone so you might want to save another copy of the file before you proceed.

Option 1 – Print to PDF

• First, you have to open the desired PDF file and tap the Ctrl + P keys to open the Print dialog box.
• After that, select the “Microsoft Print to PDF” option as the printer.
• Once the action is confirmed, it will regenerate another version of the PDF file with the default settings and merge all the existing layers into a single layer.
• On the other hand, you can also click on the “File” menu of the PDF file and select Print.
• From there, click on the Print button and select “PostScript (*.ps)” as the “Save as” type to save a PostScript copy of the original PDF file.
• Once you’re done, double click on the .ps file to open the file in the Adobe Distiller which will flatten the file automatically and convert it to a PDF file with only one visible layer.

Option 2 – Save the PDF file as an Optimized PDF file

If you are using the Acrobat Reader Pro version such as the Acrobat Pro, Foxit, and so on, you can try to flatten the layers by saving the PDF file as an Optimized PDF file. Refer to these steps to do so:

• Select File > Save as > Optimized PDF.
• Next, select the Transparency checkbox from the Settings window that opens.
• Then click on the Save button to apply and save the changes made. After that, the PDF text content should not disappear when you try to save a file on your Windows 10 computer.

If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve this Activation error is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

As you know, the Taskbar is one of the integral parts of the Windows desktop and it has been there since the release of Windows 1.0 and up until now with Windows 10. Since then, Microsoft has been modifying the Taskbar with a new design which makes it a home for new features such as Windows Search, Task View, and many more. However, there are times when you may that the Taskbar has disappeared or has stopped responding. If you experience either one of these scenarios, read on as this post will walk you through what you can do to resolve the problem. Here are some suggestions you can check out to resolve the issue with the Taskbar in Windows 10 but before you proceed, make sure that you create a System Restore point first. To do that, follow these steps:

• In the Start search, type in “create a restore point” and click the entry “System Properties”.
• Next, select the main system drive under Protection Settings and click on the Configure button.
• After that, select the “Turn on system protection” option and then click on the Apply and OK buttons to save the changes made.

Once you’ve created a System Restore point, refer to the troubleshooting steps below to fix the Taskbar in Windows 10.

Option 1 – Try to restart the Explorer process

This may sound really basic but it actually is a proven method to fix the Taskbar issue. So if anything gets stuck on the system tray or the Taskbar, you can always fix it by restarting the explorer.exe. How? Refer to these steps:

• First, right-click on the Taskbar and select the Task Manager.
• After opening the Task Manager, go to the Processes tab and look for the process named “Windows Explorer”.
• Then right-click on that process and select the option to Restart. Afterward, you should now be seeing the Taskbar as this will reload the whole Windows Shell.

Option 2 – Unhide the Taskbar using the Settings app

It is possible that the Taskbar could be hidden so you can try to unhide it using the Settings app.

• Tap the Win + I keys to open Settings.
• After that, go to Personalization > Taskbar.
• From the main section, make sure that the “Automatically hide the task in desktop mode” is toggled to the off position. However, if it’s already off then proceed to the next options below.

Option 3 – Make sure that you are not in Tablet Mode

Since Windows 10 is designed to work on both desktop and mobile devices, it could be that your computer has slipped into Tablet Mode which explains why you’re not seeing the Taskbar. To check if your computer is really in Tablet Mode, follow these steps:

• Go to the Start menu and select Settings.
• Next, select the System setting and from the left pane select the Tablet Mode.
• From there, make sure that the buttons next to the options given below are set to the off position:

You might also want to check the Projection settings as it could be the reason why Taskbar has disappeared.

• Tap the Win + P keys to open the Windows Projection settings.
• Next, make sure that you select the “PC screen only” option and then check if your Taskbar has now appeared or not.

Oobesttings error is the blue screen of death error caused by some faulty settings inside the Windows registry. The good news is that this is not a hard error to fix and if by any chance you are one of the unfortunate people getting this dreaded annoying error, please do keep reading because we have several things that you can do in order to eliminate this issue from your computer.

Reboot your system

This is the easiest and straightforward solution and can work sometimes since if the system has not been properly rebooted in a while memory could be filled with various processes and it can trigger oobesettings error. A simple restart of the system can solve the issue by decluttering files and emptying memory.

Scan and repair with SFC

If rebooting the system was not helpful and sadly you still receive an error then let's scan and repair system files by using Windows built-in tool SFC. In order to use this, we will have to run the command prompt in elevated administrator mode. Follow instructions closely. First click on the search icon on the taskbar and type in CMD The command prompt will show as a search result, on the right side click on Run as administrator. Once it opens type in following command: sfc /scannow and press ENTER Wait for the process to finish completely and restart your device after.

Repair the system registry

If the SFC scan has not repaired the issue then we will move to the next solution that involves repairing the system registry itself. Please note that you need to follow step-by-step for provided instructions since playing with the system registry can cause some serious issues if not done properly and can even render the system unstable. That being said, let's begin: Press ⊞ WINDOWS + R to open Windows run dialog Type inside regedit and press ENTER Inside registry editor locate the following key: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Session Manager/ Memory Management. and click on it to see properties Inside the properties right-click on CommitLimit value and choose delete. Confirm with yes. Close registry editor and reboot your computer.

Reset Windows 11

If even clearing key inside the registry editor has not helped next step would be to reset the system itself. Press ⊞ WINDOWS + I to open Windows settings and click on System on the left. Inside on the right part click on Recovery In recovery click on the button next to Reset this PC that says Reset PC Choose between keep my files and remove everything (a better option is remove everything, but be sure that you have all your files on a separate drive backed up) Choose between Cloud Download or Local reinstall. Click on next to confirm choices and after that on Reset to start the reset process. Follow onscreen instructions until it is fully done.

What is DownloadAdmin/ Updateadmin?

As a digital creation of Blueis, the DownloadAdmin application peruses your computer system for programs/applications that are outdated. This program then makes the necessary updates/installation on your computer, as if it were the Administrator. While most people might consider this application harmful, scrutinizing the Digital Publisher/Creator of the application should be reason enough to remove DownloadAdmin (and any other associated program) from your computer. Why? Blueis is infamous for producing/distributing “adware type software”, according to herdProtect Anti-Malware. Is that not a plausible reason for you to remove applications associated with that publisher? Additionally, DownloadAdmin not only updates your outdated applications, but it installs additional programs - usually utility tools and search toolbars. This is a sly way to promote third-party software and to get ads loaded onto your computer system. Technical details about DownloadAdmin include:

Digital Publisher: Blueis Product Version: 4.0.0.1 Original File Name: DownloadAdmin Entry Point:  0x0000234A

Assessment of DownloadAdmin

For this assessment, the DownloadAdmin file was obtained and installed on a test computer. After the DownloadAdmin/Updateadmin application was installed, it made several modifications to the computer system. These modifications may class the newly installed file as a PUP (potentially unwanted program). Outlined below is what took place after the file was installed.

• Updated an outdated application installed on the computer

Subsequent to the update made by Updateadmin, I thought the PUP had run its course. However, it was not quite finished. It was after scanning the contents/programs of my Local Drive, I stumbled on an additional program, one that I did not download or install, at least not intentionally. As predicted, the DownloadAdmin application scanned through the computer system (in the blink of an eye), during installation and made adjustments to an application already installed. This program was the Mozilla Firefox. Since Mozilla Firefox was rarely used on the PC in question, the DownloadAdmin application thought it quite appropriate to revive the Mozilla Firefox browser, by replacing it with the latest or more contemporary version.

• Installed a search toolbar

While DownloadAdmin did request permission to install an updated version of my Browser, it provided no warning about installing a search toolbar. This is quite shady and deceptive. In addition to updating the Internet Browser, DownloadAmin also installed the SearchProtect toolbar (Conduit). This toolbar is no stranger to the market as I’ve encountered it on several occasions during my assessment of malware.

Should you remove DownloadAmin?

That decision is totally yours to make. However, here are some reasons why most people would consider that program unwanted

• It updates your outdated programs

In most cases, at least those I’ve seen, if a user has a program installed, they don’t necessarily want a new version of that program. In fact, this PUP could spell trouble since some programs, especially paid, require a license to use the software. When that program is updated/ upgraded, you might have to acquire a new license to get it to work.

• Unnecessary program

If you’re totally lackadaisical and loathe the idea of doing work yourself, this program might come in handy. Many users will update their computers manually by using Microsoft’s preinstalled/pre-programmed updater in their computer’s Control Panel. This option searches for and installs all the necessary programs to keep your computer safe and secure. The DownloadAdmin program only occupies needed space and resources on your computer. However, what’s good about this program is that it doesn’t operate at the start time so it doesn’t necessarily cause unnecessary lags on your computer.

• Modifies your search experience

By installing a search toolbar called SearchProtect, Updateadmin modifies or changes the browsing experience you’re accustomed to. SearchProtect hijacks your browser and changes your homepage to their choice while removing yours. This is often hard to reverse since the publisher created this software to remain once installed.

Method Five: Use 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.

If you got an Activation Error 0xC004F211 after having installed or upgraded your Windows 10 PC, then this indicates that some hardware in your computer has changed which’s causing the error to pop up. Windows might not be able to determine if the key is used on a new computer or if it’s still the same one if you have just removed or upgraded old hardware. But worry not for this post will guide you in fixing the Windows Activation Error 0xC004F211 on your Windows 10 computer. When you encounter this error, you will see the following error message on your screen:

“Cannot activate Windows 10. Try activating again later. If that doesn’t work, contact support. Error code: 0xC004F211.”

Note that although hardware changes cause this error, the minor ones don’t really cause any issues with activation, however, if you have made any significant hardware change such as replacing your motherboard, it will most likely cause the activation error. In such cases, the Windows Activation system will treat this as new hardware and you will need a new license for that. Even if your Windows 10 computer has a genuine key, it might still fail to get activated which results in the Windows Activation Error 0xC004F211. Thus, before you do other troubleshooting steps, you need to run the Windows 10 Activation Troubleshooter first. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

In addition, there is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

What is Windows Update Error 0xC1900209? Before you can install any updates on your Windows 10 computer, there are a lot of conditions that have to be fulfilled and one of these conditions is software compatibility. It is one of the important factors in installing Windows Updates. So if one of the software in your computer is not compatible with the new Windows Update for your OS, then the Windows 10 setup will not proceed and will block the installation of the new update. This both applies to the cumulative updates and feature updates. In such cases, you will get the following error message when you run Windows Update:

“0xC1900209, Incompatible software is blocking the upgrade process. Uninstall the application and try the upgrade again.”

This error message comes under the umbrella of the Windows 10 pre-upgrade validation using Setup.exe. And for you to identify the incompatible app, you need to grab a Windows 10 install image using the Windows Media Creation tool to download the suitable Windows 10 version and mount it. After that, execute the setup.exe file that’s located in the root folder of the Windows 10 install image. Once you execute the setup file, the upgrade wizard will give you a list of incompatible apps. Once you have determined which software is not compatible with the Windows Update, there are two options you can try to resolve the Windows Update error 0xC1900209 – you can either try to update the conflicting software or uninstall it. For more details, follow the given options below.

Option 1 – Try to update the conflicting software

If you are using an older version of the software that’s in conflict with the Windows Update, you might want to update it to its latest version and then try to apply the updates again to your Windows 10 computer. You can update the concerned software by visiting the official website of the software or any of its distribution sources. On the other hand, you can also use the Check for updates feature of that particular software if it’s available.

Option 2 – Try to uninstall the conflicting software

If updating the problematic program didn’t work, the next option you can try is to uninstall it. All you have to do is follow these steps to uninstall it successfully:

• Tap the Win + R keys to open the Run dialog box.
• Then type “appwiz.cpl” in the field and tap Enter to open the Programs and Features in Control Panel.
• Next, arrange the list of installed programs in the order of the installation date.
• After that, look for the problematic program and right-click on it, and then select Uninstall.
• Once the uninstallation process is done, restart your computer and see if the Windows Update error 0xC1900209 is fixed or not.
