If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:
“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.”
Or:
“The specified product key is invalid or is unsupported by this version.”
If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC.
If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version.
Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.
The first thing you can do to resolve this Activation error is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:
There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.
Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.
Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

Here are the best ways to resolve Error Code 0xc0000005 on your Windows machine:
Always be sure to keep on other security software, such as Windows Defender, while you disable your antivirus programs, ensuring that your computer is still protected from malicious software. In general, this is usually the best security tool that you can run on your computer, without interfering with other programs.
In some cases, the error code can appear when a registry entry is either seen to be missing or faulty by the system. If you believe this is the primary cause of your problem, use a trusted registry cleaning software to scan the files and attempt to automatically fix the problem.
Always be sure to check out the provider of the registry cleaning tool that you use, as not every tool that you can download from the Internet is safe. When possible, always try to use registry tools that are directly available from the Microsoft website, rather than ones that you do a simple search for online.
Once the registry scan is complete, take the time to reboot your computer to ensure that every change that has been made can be recognized and applied by your operating system and devices.
If your drivers aren’t communicating properly with your hardware, it can cause the error code to appear. To fix this, open up your device manager software and choose to update your driver software. You can run an automatic search for updates to your drivers to make things easier.
When the driver updates have been downloaded and installed, make sure that you take the time to reboot your computer, which can allow your computer to apply and recognize any changes that have been made.Google's Pixel smartphone is one if not the best Android smartphone on the market. It regularly gets updates and Google is really trying to keep it as a top choice for Android smartphone users. One of the new things that Google has released for its smartphone series is a new emergency dialer.

With an emergency dialer, you will be able to quickly access local contact information for police, fire, and medical services. This dialer is able to contact before mentioned services even when the phone is locked and when you are traveling.
The idea is to quickly access the default emergency number no matter in which country you are currently in, service will find the appropriate number and set it as default so if you need it there is no delay in searching for the appropriate number and dialing it.
Once the service is enabled on the device you can swipe up and tap Emergency call without unlocking your phone or you can press and hold the power button for five seconds and tap Emergency.
If you have a Pixel smartphone go to the Google support page and follow instructions on how to enable this service. It costs nothing and it could potentially even save your life.
