There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).
There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.
When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.
To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.
When the command prompt opens, type in the following command, and press enter after:
slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).
While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.
Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.
This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.
To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt
The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:
