How to fix windows activation error 0xc004f074?


What is the error code 0xc004f074?

This is a windows activation error code, indicating that the license attached to your copy of Windows may have expired. The time limit was not enough for you to complete the required steps.

This may be because you did not activate windows in 30 days after purchase, or when you upgraded from an older version of windows or you probably used the key on another device?

Note that you can only use a Windows key on one device.

You can resolve this problem by starting an installation of windows with a valid license key, then activating it. If that is not possible, you will have to try the below steps to manually Activate Windows or use your 30-day grace period while waiting for a computer technician to activate your existing copy of windows.

Why does it happen?

Activation is required when your windows installation has been replaced by another one or reinstalled on top of the old one (in case any system files are corrupt). It is also needed whenever there are changes to certain components like BIOS, Hard disk controller, etc.

Before you begin please take note that this process should only be performed by advanced users. Incorrect modifications or improper edits to your registry can cause serious problems and may require the reinstallation of Windows.

It is best to create a backup of any files you modify before editing them, just in case. That way it will be much easier if anything goes wrong to restore them.

Figuring out the error code can reveal additional information about what is causing it. This may help you find a quick fix on your own, without needing Windows reinstalled.

Run the Update and Activation Troubleshooters.

This error code generally appears shortly after you install the most recent updates on your PC, so running the Update Troubleshooter may also help you resolve it.

Go to Settings > Update & Security > Troubleshooter > Windows Update and run the troubleshooter.

There is also an Activation Troubleshooter that might resolve the problem. Head to Settings > Update & Security > Troubleshooter > Activation and run it.

If you are still getting the error code after trying all of these steps, you can try entering the command slmgr /rearm into Command Prompt as another possible solution- however, this will only work three times, so it’s best to save this fix until last resort.
