Fix 0x80071AC3, Volume is dirty error message

Windows 10 supports various devices to get connected to which makes it quite a flexible operating system. The connection varies on the fact that the device can be connected either with Bluetooth or other wireless and wired connection. However, no matter how great the features are, there a few times when they bring in some bugs too. One of these bugs won’t allow you to either remove or reinstall the Bluetooth mouse and keyboard device from your Windows 10 computer. So if you are currently experiencing this problem, read on as this post will guide you in fixing it. Before you go over the suggestions laid out below, you need to create a System Restore Point first since, in one of the options, you will be making some changes with the registry files as well as some critical Windows settings. Once you have that covered, refer to the following options.

Option 1 – Configure the Bluetooth Services

The first thing you can do is configure Bluetooth Services.

• Tap the Win + R key combination to open the Run dialog box.
• After that, type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• You will then see a list of services and from there, look for the following services and make sure that their default values are set as follows:
  • Bluetooth Audio Gateway Service – Manual (Triggered)
  • Bluetooth Support Service – Manual (Triggered)
  • Bluetooth User Support Service – Manual (Triggered)
• Now click on the Start button to start all the aforementioned services and then check if you can now remove or reinstall the Bluetooth mouse and keyboard device.

Option 2 – Try running the Bluetooth Troubleshooter

As you know, Windows 10 has various troubleshooters with user-friendly interfaces where you can utilize them to fix issues in your PC. And since you’re dealing with some Bluetooth problem, you have to run the Bluetooth Troubleshooter.

• Open the Windows 10 Settings.
• Then go to Update & Security > Troubleshoot.
• You should find the option for Bluetooth on your right-hand side – click on it then click on the “Run the troubleshooter” option.
• Now follow the next screen options.

Option 3 – Try to reinstall or update the Bluetooth driver

The issue might have something to do with the Bluetooth drivers. It could be that it is outdated and needs to be updated or that you recently updated it and since then you have trouble removing the Bluetooth device and so to fix the issue, you can update, roll back or uninstall the Bluetooth drivers. How? Follow the steps below.

• Tap the Win + X keys to open the Device Manager.
• Next, look for the Bluetooth device and right-click on it.
• Select the option “Update driver”.
• After that, a new popup window will appear. In there, select the option, “Search automatically for updated driver software”.

Note: Checking the update may take a few minutes so you’ll have to wait until it finishes. If it is able to find an update, you must install it.

Option 4 – Get rid of any interference

If you have several wireless devices in the same room as your PC then it might have caused interference with the current connection in your PC which is why you have to switch off all the other devices and then try removing reinstalling the Bluetooth mouse and keyboard devices again.

Option 5 – Remove or reinstall the Bluetooth devices in a Clean Boot State

You might want to uninstall or remove the Bluetooth Devices while your computer is in a Clean Boot State. Putting your computer in this state will surely help especially if there are some processes that prevent the Bluetooth devices from being removed or reinstalled.

• 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.)
• After that, try to reinstall or remove the Bluetooth mouse and keyboard devices again.

What is Error Code 0xC004E003?

Error code 0xC004E003 almost always appears when there are damaged files in the Windows operating system. These files could be corrupt for a number of reasons and are usually a serious danger to the life of the computer system. These file errors may be caused by a number of things. Incomplete installation setup, incorrect deletion of hardware or utilities, or an unfinished file erasure. The trigger might also be in the event that the computer system is contaminated with a virus or adware or spyware, or even by the improper shut down of the computer. Any of these scenarios have the possibility to result in the removal or corruption of data of the Windows system data files.

The data system files that are damaged will give linked data and archives that are missing or wrongly linked. These are needed for the proper functioning of the software. This can also happen when or after installing third-party software that might have changed the system files. If it is suspected that a program installation will need to be stopped, it is best to let it run through the setup and then delete it later. While it installs, it is altering program files, and likely rearranging them. Stopping this in the middle can scramble files associated with the program and files vital to the usage of the computer.

Solution

Error Causes

This error will pop up after installing third-party software that has changed the system files. These system files are necessary to finish the activation process. A restore point will be necessary if it is ultimately determined that a system restore is necessary, to bring the computer back to the state it was in previous to the failed installation.

• Error code “0xC004E003” appears and does not allow the system to continue the install.
• The computer will not allow any further access or installation of the program.
• The computer may crash.
• The third-party program will not have installed completely or successfully.
• The system will not start up correctly.
• Personal files are corrupt or missing.

Further Information and Manual Repair

There are several steps that can be taken when the error code 0xC004E003 appears. It is helpful to know that this can occur from trying to install third party software. Going forward, do not attempt to install third-party software that is not trusted, and does not attempt to abruptly stop the third-party software from installing. This may cause the program to corrupt the files or delete important files. Recovering from this error can be easy if there is a recent restore point already backed up in the recovery portion of the system's files.

• Method One

Run an error scan. The problem should be resolved after rebooting the computer once these steps have been completed.

1. Download and save an error code fix utility.
2. Setup the program and then click the Scan button.
3. Click the Repair Errors button when the diagnostic has been completed successfully.
4. Reboot the computer.

• Method Two

Best when utilized by an expert.

1. Start the system up and sign in as the admin.
2. Click on Get Started, then select Programs, Accessories, Tools, and then System Restore.
3. On the next screen, click on Restore my PC to an Earlier Period, and then click Next.
4. Select the most recent system restore date within the drop-down menu of “select restore point”.
5. Click Next.
6. Click Next on the confirmation window.
7. Reboot the system after the system has finished restoring.

• Method Three

Another option for restoring. This method can be used by a novice.

1. Right-click on the Start button, then select Control Panel.
2. Look for the Control Panel for Recovery.
3. Select Recovery, then Open System Restore, then Next.
4. Choose the restore point right before the problematic installation.
5. Click Next, click Finish.

NOTE: If there are no restore points available, the system recovery may not be turned on. To check this, go to Control Panel, and select Recovery. Configure System Restore, Configure. Then, select Turn on system protection. Having a current restore point for a computer ensures the ease of recovery if any problems with the computer arise.

What is Bandoo?

Bandoo application, specifically product version 5.0.2.4762, is a bundled program. What does this mean? Simply, Bandoo, upon installation, installs additional programs, extensions, and add-ons to a computer and computer’s browser, without the knowledge of the user. This version of Bandoo concentrates on providing features for entertainment and also functionality/tools for backing up your computer files. Once executed, the file installs the iLivid Download Manager Software. Additional tools installed within the bundle include a Movie Toolbar and the thriving search engine ‘Ask.com.’ Technical details about Bandoo include: 

Digital Signature/Publisher:  Bandoo Media, Inc. Product Version: 5.0.2.4762 Entry Point:  0x000038AF

Assessment of Bandoo Potentially Unwanted Program

Interestingly, before the installation of Bandoo product version 5.0.2.4762 was complete, Spyhunter detected that the software was a PUP. After the installation was complete, product version 5.0.2.4762 of Bandoo added add-ons and extensions to both Internet Explorer and Chrome Browsers (these were the only 2 browsers used within the assessment). These appeared in the form of a Movie toolbar, providing quick access to movie trailers, reviews, ratings, and other video functionality, and ‘Ask’ (Ask.com) search engine.

Areas of Infiltration by Bandoo

Bandoo product version 5.0.2.4762 infiltrated several areas of the computer system. After installation, folders were neatly placed as files within all programs. Within “All Programs” there were 3 newly added programs. These included:

• iLivid
• Movies Search App for Chrome
• Movies Search App for Internet Explorer

The iLiVid application seems to be the main offer while the others, namely Movies App for Internet Explorer by Ask was featured as promotions or advertisements. Additionally, just below the 'END USER LICENSE AGREEMENT AND PRIVACY POLICY' a request was made that the user set Ask.com as both their homepage, new tab, and default search engine. This is just another well-concocted plan to get Internet users onto the 'Ask.com' search engine. Along with the 3 programs installed as a bundle,  a new folder was found within the computer's local drive. This program was termed OLBPre.

What is OLBPre?

OLBPre.exe is reputed as dangerous adware that weakens the security settings of a computer system. It's also covertly used for dropping files on a targeted computer, often without the user's consent or knowledge.

Manual Steps for Removal of Movie Search Apps

I found this removal pretty simple. Depending on your Operating System, there will be slight discrepancies in the manual removal steps. Using the Windows 8 (8.1) OS on your computer:

• Step 1: from your desktop, right-click on the ‘Start Button’.  A menu box will then appear.
• Step 2: from the menu box, click ‘Search’.
• Step 3: enter “Programs and Features” within the Input Box.
• Step 4: locate the installed apps. You should be able to see “Movies Search App for Chrome” & “Movies Search App for Internet Explorer”.
• Step 5: right-click on the names of the Apps (the ones you want to remove) when you’ve located them.
• Note: you will have to remove the apps one after the other.
• Step 6: after right-clicking the app, click the uninstall option (probably the only option available anyway).
• Note: If a box appears asking If you wish to ‘block’ or ‘allow’, select the allow option. That’s just the Publisher’s way to annoy you out of uninstalling the app.
• Step 7: follow instructions until the app is fully removed.
• Step 8: Repeat steps for the other app.

Since Bandoo also changed your search engine, you’ll have to reset that manually for Internet Explorer and Chrome. Follow the steps below:

• Step 1: Open your Internet Explorer browser.
• Step 2: Click the tool option located in the top right-hand corner of the page.
• Step 3: Click the “Internet Options” option.
• Step 4: Under the “General” tab, you’ll be able to see approximately 3 buttons. Click the button labeled ‘Use Default”.
• Step 5: At the bottom right-hand corner of the pop-up menu, select the “Apply” button and “OK”. That should do the trick.

Removal for Chrome Extension

This removal is simple.

• Step 1: Open your Chrome browser.
• Step 2: A pop-up box will be visible.
• Step 3: Click the “Remove from Chrome” option.

After removing the extensions/add-ons, perform another scan with Spyhunter. You’ll pick up a few threats. The second scan should clear up everything. To completely remove Bandoo from your computer, click here to download and install Spyhunter.

Computer viruses are malicious applications that have the ability to self replicate and spread over the system and various devices, just like viruses in organisms. We all know that computer viruses are bad and that you should avoid them however you can. So in this spirit, we are taking a deeper dive into what kind of viruses exist and how they function.

1. File-infecting Virus

A virus that attached itself to an executable program. It is also called a parasitic virus which typically infects files with .exe or .com extensions. Some file infectors can overwrite host files and others can damage your hard drive’s formatting.

2. Macro Virus

This type of virus is commonly found in programs such as Microsoft Word or Excel. These viruses are usually stored as part of a document and can spread when the files are transmitted to other computers, often through email attachments.

3. Browser Hijacker

This virus targets and alters your browser setting. It is often called a browser redirect virus because it redirects your browser to other malicious websites that you don’t have any intention of visiting. This virus can pose other threats such as changing the default home page of your browser.

4. Web Scripting Virus

A very sneaky virus that targets popular websites. What this virus does is overwrite code on a website and insert links that can install malicious software on your device. Web scripting viruses can steal your cookies and use the information to post on your behalf on the infected website.

5. Boot Sector Virus

These viruses are once common back when computers are booted from floppy disks. Today, these viruses are found distributed in forms of physical media such as external hard drives or USB. If the computer is infected with a boot sector virus, it automatically loads into the memory enabling control of your computer.

6. Polymorphic Virus

This virus has the capability to evade anti-virus programs since it can change codes every time an infected file is performed.

7. Resident Virus

A resident virus stores itself on your computer’s memory which allows it to infect files on your computer. This virus can interfere with your operating system leading to file and program corruption.

8. Multipartite Virus

A type of virus that is very infectious and can easily spread on your computer system. It can infect multiple parts of a system including memory, files, and boot sector which makes it difficult to contain.

Receiving a screen of death is not a pleasant experience at all and most users would agree that they would very much like not to face one during their work with the computer. Sadly PC is not a perfect machine and it is not working in a perfect environment so errors happen. The most famous and well-known death screen is blue which is also the most common one, my bet would be that there is not a user which has not been faced with this blue error screen. There is no simple explanation why these stop errors occur as several factors can be involved. However, it is known that the malfunctioning of hardware drivers or drivers that are installed by third-party software drive this unwanted change. But did you know that there is more colors for infamous death screens and not just blue one? Microsoft has coded different errors to different colors in the goal for the technical team to be aware right away of what type and kind of error they are dealing with. Color for screen errors are: Blue, Black, Pink, Brown, Yellow, Red, Orange, Green and White If you are interested in what color represents what keep reading.

BLUE

A stop error or exception error commonly called the blue screen of death (BSoD) or blue screen, is an error screen displayed on Windows computers following a fatal system error. It indicates a system crash, in which the operating system has reached a condition where it can no longer operate safely. This is caused by many different problems, such as a general hardware failure or a crucial process terminating unexpectedly.

---

BLACK

On Windows 10 systems, a Black Screen of Death can be caused by an unfinished Windows Update. To resolve this problem, simply hold the power button down on your PC or laptop to switch off the computer. A cold start should result in the system booting properly.

---

PINK

It is a diagnostic screen with a white type on a pink background. Pink Screen is mainly seen when the VMkernel of an ESX/ESXi host experiences a critical error, becomes inoperative, and terminates any virtual machines that are running. It is not fatal and generally considered more of a developer testing issue. When encountered, it can be fixed quickly by following the simple action of pressing and holding your computer’s power button to shut down the device.

---

BROWN

The Microsoft Windows 10 Operating System Brown Screen of Death is an on-screen fatal error notification with bug check codes which is seen when a computer crashes due to graphics hardware or software-related problems (failing graphics drivers).

---

YELLOW

It affects the functioning of a browser, particularly Mozilla Firefox. The Yellow Screen of Death makes the appearance with a weird buzzing sound in the background when the XML parser refuses to process an XML document causing a parsing error and a weird buzzing sound. The issue persists unless the computer is manually rebooted.

---

RED

Commonly the Windows 10 red screen is caused due to the hardware error, particularly if you overclock your Windows PC/laptop. Despite this, sometimes the red screen of death is also caused by outdated or incompatible drivers or due to BIOS issues.

---

ORANGE

The Orange Screen of Death on Windows occurs due to fatal hardware errors. Multiple reasons have been reported for the Orange Screen of Death. Some had this issue when watching a YouTube video, some were not able to boot into Windows. It can even occur when waking up from Sleep.

---

GREEN

The green screen of death only appears when you're running an Insider Preview version of Windows 10. It's the same as the blue screen of death, and it will show the same error messages. ... If you see a green screen of death (GSOD) on your PC, that's a sign you're using an Insider Preview build of Windows 10.

---

WHITE

The White Screen on Windows is also an error where the screen of the computer just turns white and freezes. There can be several things that can cause the white screen to appear on the Windows laptop monitor. But the main issue could be because of malfunctioning of the graphics hardware.

TCI/IP or as known as Internet protocol is one that controls packets that are sent over the internet and makes sure that each one has reached its destination so you can pleasantly browse your favorite websites. The setting for the given protocol is stored locally on your machine and most of the time, everything works fine and good, but sometimes, these settings can get corrupted.

Malware or other software can temper with setting making TCP/IP making it wrong and throwing nondescript connection errors in your face. If you are faced with this issue worry not because fixing this issue is really easy.

Before we actually go and fix the issue please do scan your system with your protection suite just to be sure that if there is any kind of malware on the system it is properly removed from it.

Resetting TCP/IP

First thing is to open search and find PowerShell, press the Windows key on the keyboard, and type in PowerShell so search results are shown. Click on Run as administrator to open PowerShell in elevated mode.

Once PowerShell is opened type indie it:

netsh IP reset and press ENTER. The task will start executing and at this point you will see a lot of Resetting, OK! messages. Once everything is finished restart your PC and you are good to go.

As previously announced by Google feature to quickly delete the last 15min of browsing history via one button is rolling out now. For now, only Apple users will be available to use this feature but the Android update is scheduled for later this year, a strange move by Google but it is what it is. For anyone who is unfamiliar with this feature, basically, Google wants a quick way to remove the last 15min of browsing history as a supposedly stated request to make deleting browsing history much easier. Google came up with this idea so you can keep the previous history intact but remove just 15min time frame, no additional explanation was given on why 15 but I presume it is some round number that came up as the middle one with research, read telemetry info. Using quick delete requires being signed into Search with a Google account. Users can access the option by simply tapping on the avatar icon to access the settings then choosing "Delete last 15 minutes."

Building your skill set could be a very important thing, especially in today’s world, and what’s the best way other than online learning classes. You are not exposing yourself to pandemics, staying safe in the warmth of your home and most of the courses are free. Presented here are sites that I believe will and can help you with your goal of learning desired material whatever that might be. Sites are listed in no particular order with a description of what each has to offer.

Coursera

https://www.coursera.org/ Coursera was one of the pioneers when it comes to college education online. When it started all courses were free and offered certificates if the taker has done tasks with a passing grade. Today not everything is free but still, there are tons of free courses that can help you to learn something new and to advance in your work or hobby. Google is using the Coursera platform to deliver its courses to the audience and besides google a lot of academic professors from Princeton, Stanford, John Hopkins and many more are presently offering their course material.

edX

https://www.edx.org/ edX has evolved from MITx, MIT’s free initiative to place some free academic lectures from its classrooms free into the world. Since it was rebranded into edX it started including other big university names like Berkeley, University of Texas System, Harvard, and many more. Since its infant days, edX has expanded and included many areas that it offers coursework from arts to science. Certificated today are mostly not free but course videos are, so if you care to learn and not wave certificates around this is a great place to do it.

Udemy

https://www.udemy.com/ Udemy has a little different approach to course material than previously mentioned websites. Teachers on Udemy are mostly people that are working in a given field. Programmers will teach programming, fitness instructors will teach training, etc. There are vas variety of topics even on lifestyle, hobbies even gaming to more serious ones like software developing hardware, etc. There are free courses but mostly are one-time purchases with unlimited access to course material and with frequent discounts udemy might be a good place to look if you can find anything interesting.

Alison

https://alison.com/ Alison is kind of Udemy if we are talking about course material and who is teaching, the difference however is that it has more free content and it is one of the rare websites on this list that has Language courses. Courses vary from beginner level to more advanced ones.

Udacity

https://www.udacity.com/ Udacity was also one of the earlier websites to offer free courses, in today’s world it still has free material but there is also paying one. The big difference from other competitors is that Udacity focuses mostly on programming, data science, and web development and it is very strong in this field. There are no courses about art. Music or similar, mostly IT stuff is covered here. If this is something that interests you, make a free account and give it a go.

Codecademy

https://www.codecademy.com/ Codecademy is a website mainly focused on teaching you how to code. Pro plan is there but there are a lot of basic and free courses on the mentioned subject. The curriculum is really wide covering Python, R, Java, JavaScript, SQL, Ruby, C#, C++, Swift, PHP, HTML, CSS and more so I am sure that if you are interested in coding this would be a pretty good place to find things. Besides pure language coding courses site offers also, Cybersecurity, Web design, Data science, web development, Game Development, Mobile Development, and many more courses on provided subjects.

Academic Earth

https://academicearth.org/ Academic Earth has been built with one simple premise: Everyone deserves access to education. Lead by this kind of mindset on Academic Earth you will find well, academic courses similar to ones found on edX and Coursera, but from mentioned sites here all courses are free and you will find only academic ones, there are no entrepreneur or expert courses here, just pure academic ones. If you wish to see and learn something the way it is taught in Harvard, Berkeley, MIT, etc this is the place for you.

Khan Academy

https://www.khanacademy.org/ Khan academy is completely free and it is offering courses matching certain grades for children. It is offering courses for all 8 years of elementary school, math courses for high school and college with some coursework on topics like science, arts & humanities, reading, life skills, etc. Despite not being on the same level as some university courses presented on other mentioned websites Khan Academy is a good place to learn a lot of basic skills that you could build upon later.

Conclusion

I hope that I have helped you in some way to expand your skill set and learn something new with provided sources and I hope to see you again on errortools.com
