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.

Error Causes
Originally Microsoft has imagined its widgets menu as Microsoft-only widgets but it seems that they have changed their mind.
Due to the latest leak, it seems that Microsoft will open the widgets menu to 3rd party developers as well but at launch, it will be only official widgets. It was hinted that later widgets menu will be open to developers who want to bring their own stuff into it.
Distribution, date, and technology that will need to be used in order to create your widget have not been discussed nor leaked at a given time but in some way, I am very glad that at least some customization will be in Windows 11.
It is funny and amusing how some things that were in Windows Vista are getting back like glass design, round corners, and widgets. Let’s just hope Windows 11 will be a better Windows than Vista was. ListenToTheRadioNow is a Browser Extension that allegedly lets you listen to radio from your browser. However, all this extension does is add links to the popular radio stations on your home page. This extension hijacks your home page and changes your default search provides to MyWay. While running it monitors browsing data from your browser, mining information such as website visits, clicked links, and sometimes even personal information.

So, you have finished with work, game, movie, music, email, or whatever on your PC, you look at the clock, it is late, you decide to go to sleep or outside, you click on the power button and choose shutdown. Now when a PC is shut down you feel good and go with your business but the next time you power it up you get the same error like the computer never really shut down in the first place. You wonder why and reboot it, just in case and all of the sudden error is gone.
If something similar has happened to you or you had the feeling that after shutting down your computer has not really felt like shutting it down, do not seek professional help, everything is OK with you because when you click on shut down, your computer does not really shut down!
Truth is that Microsoft has changed how to shut down works and how rebooting works in Windows with an update but has not publicly said anything about it so some users may experience this feeling of not shutdown phenomenon and might even think there is something wrong with their PC.
A few years ago shutdown button and option in Windows were really shutting down OS, but things changed when Microsoft wanted to increase boot-up speed. Now when that decision was made shutdown option was changed. So, what was changed? Well in order to increase Windows booting time, the shutdown will now turn off power to PC components and it will look like everything is indeed shutdown but the Windows kernel will actually be saved to a hard drive with all settings and just awaken once the PC is turned back ON. This will result in all errors and other stuff being just still present same as they were once the system was instructed to be turned off.
Rebooting your PC will now clear kernel and file from the hard drive and you will get a clean system startup without any issues tied with the kernel itself.
Now that we know why and what change has been made to Windows logical question is can we shut down our PC at all properly? Luckily for us, the answer is yes and we will not need any external application to do it, we can still do it inside Windows itself and it is quite quick and easy.
In order to bring the old shutdown functionality of your PC please follow the instructions but be aware that by doing this your PC will boot a little bit slower since it will have to load the kernel from scratch each time computer is turned ON.
First thing is to go to settings and go to System

Then once you are inside the system, navigate to the power and sleep and click on it to select it. Once you have it selected to all the way to the right and click on additional power settings.

When you click on advanced power settings you should be led to the control panel's power options. Inside this panel click on top left link where it says Choose what the power button does.

Inside options, you will need to untick the box next to Turn on fast startup (recommended), this option has been ticked ON by the Windows update and probably without notifying you. Option means exactly what was described, it will save kernel state on the hard drive for faster boot time but sadly it can cause some issues since it will never be reloaded from 0.
If you are unable to uncheck the box click on the text beside the shield icon that says: Change settings that are currently unavailable (you will have to be logged in as administrator).

Altho turning off fast startup and shutting down the PC completely will for sure extend your bootup time I still believe that it is the right choice since sometimes a lot of clutter and bad things accumulate over time inside the OS and can cause a vast variety of problems in a long run. So stay safe and shut down that PC as it used to be in the past.
How this is the case we have decided to put a little tutorial on how to accomplish this very task and run file explorer with administrator privileges.
