Fix The driver detected a controller error

In recent times, some Windows 10 users have seen an error code BCM20702A0, when using Bluetooth and they are concerned as to what it is all about. We can say for certain that it has something to do with your Bluetooth driver. The error message in question is:

The drivers for this device are not installed. There are no compatible drivers for this device.

The problem here tends to no longer allow specific Bluetooth components to properly communicate with your Windows 10 operating system. It also affects laptops that do not have native Bluetooth support; therefore, the manufacturer installed a dongle on the inside to deliver the service. This is not the best way to do things because native support is always better. On the other hand, maybe you’re using a Broadcom USB Bluetooth dongle that is acting up, and as such, the error is showing. Below are solutions provided for this particular error and how to eliminate it.

1. Run the Bluetooth Troubleshooter

   Press ⊞ WINDOWS to open the menu and select settings In settings choose Update & Security Go to troubleshoot and on the right panel click on additional troubleshooters Click on Bluetooth Select Run the troubleshooter, then sit back and allow the tool to do its thing. Once you’ve completed the task, click on Apply this fix if any repairs are needed Reboot your computer

2. Install Broadcom driver from official website

   Windows drivers for Broadcom Bluetooth devices are no longer posted on their website. They should be available through Microsoft’s Windows Update service. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update. However, the Broadcom Bluetooth drivers seem to be available here on the Lenovo website. To fix the BCM20702A0 driver error, you may download and install them. After downloading it, right-click on the downloaded item, and select Run as administrator. After installation, restart your computer, then check again if it works.

3. Remove all Bluetooth drivers and USB controllers

   If previous solutions did not work, go to device manager and remove all Bluetooth devices along with all USB controllers. Reboot your computer and Windows will automatically reinstall and set all devices.

Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:

“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”

Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 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.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.

• Extract the Windows 10 ISO files using an extractor.
• Then browse to the folder you created and go to the sources folder.
• From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:

[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Note: “xxxxx” is the KEY to your Windows version.

• Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.

Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

The latest security vulnerability was discovered inside both Windows 10 and Windows 11 letting any user access admin privileges inside the operating system. This can, of course, be used by a potential attacker to get full control of the system. The problem lies in Microsoft's security rules assigned to the Windows Registry and the Security Account Manager. Both for some reason have reduced restrictions allowing any local user to fully access the files without administrator privileges. The problem is even more amplified if we think about Security Account Manager which includes all account data including the passwords of all users using the same PC. This can provide a potential attacker with all information and let them log on into the administrator account for full control. Microsoft is aware of the matter and is tracking it with code CVE-2021-36934, and includes a complete workaround for the issue, which includes restricting access to  %windir%\system32\config and deleting any restore points or Shadow volumes that were created before that point until the hole is plugged with an official security patch.
