As you know, Windows 10 has a complicated mechanism for Activation which helps in the verification of a genuine copy of Windows 10. However, there are times when you might encounter some errors during the activation process. One of these errors is the error code 0xc000f074. This kind of error could be due to the Key Management Service or KMS which is unreachable by the client computer or if the key used in the SLSetAuthenticationData function call is incorrect.
This kind of error mostly affects surfaces on computers that are upgraded from either Windows 7 or Windows 8.1 to Windows 10. In such cases, you may encounter any of the following error messages:
“Windows is unable to reach your company’s activation service. Please connect to your corporate network. If you are connected and continue to see the error, contact your system administrator. You can also click on the error detail to find the exact error. Error code: 0xC004F074.”
“Activating Windows(R),

Error: 0xC004F074 The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted.
Please see the Application Event Log for additional information.”
“Error 0xC004F074, SL_E_AUTHN_MISMATCHED_KEY, The Software Licensing Service reported that the key is mismatched.”
To fix the Windows 10 Activation error 0xC004F078, you have to use the correct key for your type of Windows copy or use Command Prompt to reinstall the key or you could also try running the Activation troubleshooter.
The first thing you can do to resolve the Activation error code 0xc000f074 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:
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.
If the Windows Activation troubleshooter wasn’t able to resolve the error, then you can try using the correct key for your type of Windows version. All you have to do so is check the type of your Windows copy if it’s OEM, retail, or volume. And make sure that you have the correct, valid product key for your operating system.
If you’re at your wits’ end in trying to upgrade your computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation error code 0xc000f074 a lot easier and faster.
If you have a Runtime Error 339 issue on your computer, here is a great way how you can fix it right away:
Error Code 46 is a device driver error that occurs when Windows fails to access the connected peripheral device to the computer as Windows is in a process of shutting down.
Users experience this error on any Windows 2000 and later operating system versions and usually see a pop-up with the following message:
“Windows cannot gain access to this hardware device because the operating system is in the process of shutting down. (Code 46)”
Error Code 46 is caused when there is a temporary problem with windows system files which prompts that the system is undergoing a shut down when in fact is it not.
This prevents access to the connected devices. This error may also be caused by a registry issue in which case it has either become corrupted or damaged.
Unlike all other Windows error codes, code 46 is relatively easy to fix with the right knowledge and does not pose any serious threat to the well-being of your PC. Here is how you can do it.
The simplest method to resolve Error Code 46 is to run a restart of your computer.
The error is most commonly a temporary registry glitch that prevents you from accessing the device connected to your computer. Upon restarting your computer, it will resume working properly as before.
There is no need to run a troubleshooting wizard, use system restore, or run anti-virus software to scan and remove malware or spyware. A simple restart is all that is needed.
Although the error code can be resolved upon restarting the computer, there’s a possibility of damaged or corrupted Windows registry files. This can be fixed by using a program like DriverFIX.

Error code 0x80073afc deals with an antivirus program first built into Windows 8/8.1 This error occurs when Windows Defender, the built-in anti-virus software in Windows 8/8.1 and higher, does not start automatically and users attempt to manually start the program. During the initialization period of the program start-up, something goes wrong and users get a 0x80073afc Error message. The error message states there was a problem with the initialization of the program. Windows Defender provides protection of your computer and it is advised by the Microsoft Corporation that you ensure it starts up automatically on every start-up.
Users have found several manual repairs that have fixed the problem without needing to contact technicians for extra help. While the methods below should solve your problem easily, if this is the first time you have encountered the issue you may want to do a simple restart. This has fixed the problem for some users and is the easiest first troubleshooting move. If it doesn’t work move on to the methods listed below, which are easily completed without extra help.
Before trying any of these methods, please make sure that you are logged into a profile that is listed as the administrator of the computer of his administrative powers enabled. If this is not the case you will not be able to complete the following methods. Please log out and log back in on the administrator profile.
First, check to see if you have a third-party anti-virus program installed on your computer. Some users believe that the built-in Windows Defender program is not powerful enough to handle the safety of their computer so they usually download a third-party program. However, that program may have caused a conflict with Windows Defender and may not allow it to open. If you do have a third-party program installed, try uninstalling it then manually starting Windows Defender.
If method one does not work, you may be infected by malware or a virus that has tampered with the settings on your computer and will not allow Windows Defender to start automatically or manually.
First, open Run by holding the “Win” key and pressing the “R” key. Then type “Regedit”. The program will ask for permission to follow through with this action. Click on “Yes” and the Open Registry Editor will open.
Find the HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionImage File Execution Option and check to see if there are any files similar to MSASCui.exe or MpCmdRun.exe. If there are any file entries that resemble that, you will want to right-click on them before selecting the “Delete” option. If you do not see any entries that match, this is not the issue with your Windows Defender and you will want to try another method.
The Registry on your computer is very important. It helps tell your computer what programs are safe to run, what programs should be run, and what programs should not be run. If it is tampered with by a virus or Malware, multiple system operations can be affected.
However, if you did find similar file names, and you deleted them, try to start Windows Defender manually. If it does not work again, move on to the next method.
If the first two methods do not work for your issue, and you are still receiving error code 0x80073afc when attempting to start Windows Defender, this step should solve the problem if you have Restore Point installed on your computer, which you most likely do.
For this method, we will be restoring your computer to a previous Restore Point. First, just like in method two, hold the “Win” key and press the “R” key. This will open run. Next type “Rstrui.exe” and click “ok”. After some time, you will see System Restore Windows. Click “Next” and select the restore point that you would like to go back to. After your computer has restored to the point you selected, check to ensure that Windows Defender has started correctly.
If the above methods aren't able to rectify the issue, you might have to download and install a powerful automated tool to get the job done.
