If the Error Code 0xC004C770 popped up on your computer during your activation of the Windows 10 software, don’t worry. This is a fairly common error, especially for people who own more than one computer upon which Windows 10 is installed and activated. The gist of this error code is that the product key that you have entered has already been claimed or used on a different computer. Because there are limitations on the number of computers that can use any given license activation code or product key, this error code can arise when you have exceeded that limit. If you have a single-use license and have already entered the particular product key onto another machine, you may see this error come up during activation.
Both Error Code 0xC004C770 and Error Code 0x803FA071 arise from the same problem and the same steps can be used to resolve both error codes.
Error CausesError Code 0xC004C770 is likely to appear on your screen during activation of Windows 10 if you or anyone else in your organization have already entered in the product key used on another computer. If you have a multiple-use license, the product key that you are entering may already have been used for the maximum number of computers allowed under that license.

Many are upgrading their OS to Windows 10, however, it’s not always smooth sailing because users have been reportedly experiencing different bugs including Black Screen after a successful update.
One common issue in installing Windows 10 is the appearance of a black screen after installation. This usually occurs when the user restarts the computer. Initially, there will be a black screen only appearing on the monitor. There are also cases where a mouse cursor is present, while some cases have no cursor at all.
Not only that, it seemed that you’ve lost all your desktop icons when experiencing this bug.
Error CausesJust like the other bugs experienced by Windows 10 users, booting to a black screen has reasons. Before you even try to look for the solution, you first have to determine the cause of the error, in this case, the error would be black screen when booting.
Before you even think of upgrading your OS to Windows 10, you need to know that there are specific system requirements and specifications to be able to successfully update your operating system.
There are more system requirements in order to use other certain Windows 10 features, but we’ll focus on solving your black screen problem in this article.
IMPORTANT NOTE: While it’s possible that you’ll be able to find the solution for your black screen during Windows 10 update, contacting the service of a professional technician or using an automated tool is advisable if you’re not confident in performing the methods to be discussed.
There’s a chance that you’ll get an error prompt saying, “installation cannot be completed in safe mode.” If this happens, simply press Shift + F10. This command will redirect you to the Command Prompt. You just open Device Manager by keying in devmgmt.msc then disable the display adapters, now check if you’ll be able to successfully boot in normal mode.
This process will normally allow you to complete the Windows 10 installation, if that’s the case you can just update the display adapter drivers from the manufacturer’s website. Restart your computer and see if this solves the problem.
Do take note, however, that the Roll Back Driver option is not available if there was no previous version installed.
Since one common cause of black screen during a Windows 10 update is the external devices you use in your computer, you might want to consider these steps as well.
Some Windows 10 users had success in solving their black screen problem by disabling the fast startup.

Error CausesError 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.
Error CausesThis 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.
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.
Run an error scan. The problem should be resolved after rebooting the computer once these steps have been completed.
Best when utilized by an expert.
Another option for restoring. This method can be used by a novice.
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.
