Bluetooth A2dp Source not working Code 52

A number of users have recently reported that they were going through an issue with their Bluetooth devices on their Windows 10 computers. This issue involves an error saying,

“Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52).”

If you are one of the users who encountered this kind of error on your Windows 10 computer, read on as this post will guide you on how you can fix this Bluetooth error. According to security experts, the key to fixing this error is to sign the Bluetooth A2DP files with the built-in tool, System File Checker. Apart from that, you could also run the Hardware and Devices troubleshooter or perform System Restore, as well as update or reinstall the concerned drivers. For more details, refer to each one of the options provided below.

Option 1 – Try to check Bluetooth-related services

In Services, there is a Bluetooth-related service that helps users use Bluetooth so if that particular service suddenly malfunctions for some reason, you will most likely get the “Windows was unable to connect with your Bluetooth network device” error message. That’s why you need to check Services and to do that, refer to these steps:

  • Tap Win + R keys to open Run prompt and type in “services.msc” then tap Enter to open Services.
  • Next, look for the Bluetooth Support Service and double click on it to open Properties.
  • From there, verify if the Service status is showing “Running” or “Stopped”. If it’s the latter, you have to click the Start button.
  • Lastly, check if the Startup type is set to Manual.

Option 2 – Try running System File Checker or SFC scan

You could also run System File Checker or SFC scan to fix the Bluetooth error. It is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

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

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Reboot your PC.

Option 3 – Try to perform System Restore

You might also want to perform System Restore as the error might be caused by system modifications. Thus, to undo them, you can use System Restore. Run it using these steps:

  • First, tap the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.
  • Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
  • After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 4 – Try running the Hardware and Devices Troubleshooter

The next thing you can do to fix the problem is to run the Hardware and Devices troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the Bluetooth error. To use it, refer to these steps:

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

Option 5 – 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 devices 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. And if you want to reinstall the Bluetooth driver, just select the “Uninstall driver” option and follow the next on-screen instructions that follow.

How to remove PC Fix Speed from your Windows PC

PC Fix Speed is a Potentially Unwanted Program designed to improve the speed of your computer. This program usually comes bundled with other software, and when installs automatically scan your PC and displays exaggerated messages on the status of the PC’s performance, to get users to pay for the PRO version of the software. It also adds registry entities that allow it to run each time the computer is started, and the application itself will constantly keep reminding users that they have errors by putting the application windows on top.

From the Author: The Service is provided by PCRx through Crawler, LLC. Clean and repair your PC’s registry, optimize PC performance and free up disk and memory space. With everything you do on your PC, including adding on devices, a new entry is created in your Windows® registry, and seldom are any removed after they’re no longer needed. As a result, your PC gets bogged down with unnecessary entries, slowing your PC speed, the start-up, and your Internet browser. PC Fix Speed cleans up registry entries and puts your PC back on track for optimal performance. PC Fix Speed is an essential application that should be a part of every computer. PC Fix Speed especially helps computers that are unusually slow, freeze up often or show error messages, by cleaning the system registry and improving overall performance.

About Potentially Unwanted Applications

If you have ever downloaded software from the internet (shareware, freeware, etc,), it’s quite possible you’ve unconsciously installed unwanted programs on your computer system. A Potentially Unwanted Program, often known as PUP, in short, is software that contains adware, installs toolbars, or has other hidden goals. These kinds of programs are usually bundled up with free applications that you download from the internet or will also be bundled inside the custom installers on many download sites. It’s clear by its name – unwanted programs – but did not actually constitute “malware” in the traditional sense. An important difference between malware and PUP is distribution. Malware is normally dropped through vulnerability exploitation while PUP gets installed with the consent of the user, who intentionally or unwittingly approves the PUP installation on their computer. PUP developers can argue their programs aren’t malicious software however, it can nevertheless be unsafe software and put your PC at risk much the same way malware does.

Exactly how do PUPs look like?

Unwanted programs come in various forms. More often, they can be found in adware bundlers which are known to utilize aggressive and misleading advertising. Most bundlers install many adware programs from a number of vendors, each of which possesses its own EULA policy. Safebytes Anti-malware entirely eliminates this threat and safeguards your computer against unwanted programs or adware infection. Several PUPs also show up as toolbars or add-ons, mounted on your preferred web browser. These toolbars change your homepage and your search engine in the installed browser, track your web activities, control your search results with redirects and sponsored links, and eventually slow down your browser and diminish your web browsing experience. Potentially Unwanted Programs occasionally act very much like viruses or spyware. Some PUPs carry keyloggers, dialers, and other software to collect your personal details that can cause identity theft. Because of this unwanted program, your application may freeze, your security protections can get disabled which could leave your computer susceptible, your system may get ruined, and the list goes on and on.

Some tips on protecting yourself from PUPs

• Read meticulously before you install anything. Don’t click accept until you have read the fine print. There could be a clause about PUPs. • Use ONLY custom or manual install method – and don’t blindly click Next, Next, Next. • Use good anti-malware software. Try Safebytes Anti-malware which can spot PUPs and handle them as malware by flagging them for removal. • Be alert if you install freeware, open-source programs, or shareware. Disable or eliminate toolbars and browser extensions you don’t really need. • Only download applications from the original providers’ websites. Avoid download portals since they use their very own download manager to pack additional programs together with the initial download. Remember the fact that although PUPs could cause damage and hinder the proper function of the computer, they can’t get into your system without your consent, so be watchful not to provide them with it.

Fix update failed to install error 0xca00a000
This post will show you how to fix the Windows update error 0xca00a000 which you can encounter during the installation of Windows updates. Here’s the full error message of this Windows Update error:
“Updates failed There were problems installing some updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: 2018-07 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4345421) – Error 0xca00a000”
This kind of Windows Update error pops up when Windows has missed installing one of the cumulative updates needed or when there is some problem with the driver that won’t let the installation of the updates push through. There are also instances when the system files are modified with incorrect permission that may result in the Windows update error 0xca00a000. Thus, you need to fix the trusted installer permission as well as resolve the issue with the driver. To do these things, you need to follow the options laid out below.

Option 1 – Run the Windows Module Installer

The Windows Module Installer is a built-in service in the Windows operating system that could help you resolve the Windows update error 0xca00a000. You need to make sure that this service is Started and that its Startup type is set to Automatic – you can do this via Services Manager or by executing the command given below in an elevated Command Prompt.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “command prompt” in the field and hit Enter to open Command Prompt.
  • And in the elevated Command Prompt type in the following command and hit Enter:
SC config trustedinstaller start=auto
  • After executing the command successfully, you should see the “[SC] ChangeServiceConfig SUCCESS” message on the Command Prompt window.

Option 2 – Try manually installing the updates

As mentioned, the error might be because Windows missed installing a particular update which is why you are not able to proceed with the current update. So to resolve the issue, you need to install the update that wasn’t installed by downloading it from the Microsoft Update Catalog website. You also have to make sure that you didn’t turn off the Windows update or have it delayed.

Option 3 – Delete the files from the Software Distribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.
  • Open the WinX Menu.
  • From there, open Command Prompt as admin.
  • Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauserv net stop bits
  • After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
  • Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
  • Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.
net start wuauserv net start bits
Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.
  • Now Open Settings and check for Windows Updates. Windows 10 should begin the download right away.

Option 4 – Install the updates in a Clean Boot State

You might want to try putting your computer in a Clean Boot state and then install Windows Updates again without any trouble. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.
  • Log onto your PC as an administrator.
