How to Fix Windows 10 Activation Error 0x004f074 Windows by Osman Ali - December 26, 20190 “Error 0x004f074” is a problem that many users are experiencing at the moment, not only on Windows 8, but also during the update or upgrade to Windows 10 and is still widespread. This problem occurs when the system can not locate the correct activation key or not originally purchased the operating system. In short, if you do not have or can not provide the original activation key, the activation error will occur. As long as you have the original Windows 10 operating system, it is a feature that can be modified after a few modifications in the system. This will be the topic I will discuss and make some steps on how to resolve it. All steps are simplified to better understand and solve the problem easily in the shortest possible time. Please note that two similar issues are not guaranteed by the same procedure and decision. However, it’s still better to tell you that if you know someone who has more knowledge about troubleshooting personal computers, you can then let them take them. Otherwise, bring your computer/laptop to the nearest service centre or schedule a technician to come to your home.

As I said, there are no similar issues with the same resolution. To narrow the problem, follow the recommended actions below: Step 1: Uninstall the existing activation key In this procedure, we need to re-enter the activation key to your operating system.

Then, wait until the proxy gives you the new activation ID. Once you have the new activation ID, continue and enter it. If the action is successful, let the agent know immediately and then close the chat. Once you’re done, it’s good to restart the computer and see if the problem still occurs.
