After the release of Windows 8,then 8.1, more users are switching to the new OS. One of the early reported problems is the issues related to activation error 0xC004F074. After installing, you are supposed to activate windows. But some users have reported an error code 0xC004F074 during the time of activation.
This error code appears only during the time of activation when the Software Licensing Service reports that it cannot activate the product key since the Key Management Service cannot be contacted.
The steps below will help you fix the problem easily. This can also be tried for the error code 0x8007232B.
- Open cmd(command prompt) with administrator rights
- Type slmgr.vbs –ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (x should be replaced by your 25 digit product key)

Other methods to try
The issue might be with corrupt system files. Run an SFC scan.

- Type sfc /scannow
Try activating, once the scan is complete. If the scan produced errors,this might be a problem with corrupted system files that needs to be taken care of.
The product key has exceeded its unlock limit
Trying to activate too many times can lead to a server error “the product key has exceeded its unlock limit”. Once you get this message, there are only 2 things to do.
- Dial the automated system and try to activate product by phone.
- If that failed, talk to a Microsoft technician. Be prepared with details of your purchase of product as the technician is sure to ask questions to confirm if the product is genuine. Once confirmed, they will reset the product key on their server and you wont have any more problems in activating.
