Activate Windows. Error code 0x8007007b: how to fix it?

As you know, in order to use Windows operating systems in full-function mode, it is not enough to simply install them on a computer. It is also necessary to activate the product using a special key. However, in systems of the seventh, eighth and tenth versions, a failure sometimes occurs, in the description of which the error code is 0x8007007b. With what it is connected and how to fix the problem, see below.

Error code 0x8007007b when activating "Winds 10", 8, 7: reasons for the appearance

In addition to the activation code itself, the notification contains a brief description of the problem. In general terms, it can be treated as an incorrect syntax, and, more simply, the input of an incorrect key. This can be observed when a user attempts to use a key for another version of the system for their version of the system, or simply incorrectly enters numbers and letters.

But the most important problem is that the message specifies only error code 0x8007007b and description, and from the bottom there is only one button to close the active window. That's incomprehensible to some users, where to enter the key, if the system itself does not offer any opportunities for this? There is an exit. To carry out the activation process with the correct key entry, there are at least two simple solutions.

Error code 0x8007007b: how to fix it? Method one

To be sure that this situation is connected with the lack of a license, we will first make sure that it really does not exist.

To do this, call the command line (cmd in the "Run" menu) and register in it the execution of a special script slmgr -dlv. If the license status bar indicates that it is missing, we begin to fix the problem.

We call the console "Run" (quick call - keys Win + R) and enter the command slui 3. In the appeared window there is a special line in which you need to enter the desired 25-digit code. If the entry is correct, the system will inform you that the activation was successful. If the user receives a notification that the key was successfully installed, but the activation does not occur, and the message, in which error code 0x8007007b is present, appears again, proceed to the second procedure, which, in general, is not much different from the first.

The second method

The second method of eliminating the problem with activation is to use the above service, which was used to check the status of the license.

In this case, you should go back to the command line, where both the activation command and the key are prescribed. It looks like this: slmgr.vbs -ipk 12345-12345-12345-12345-12345, where instead of the set of digits in this example, you need to enter the key value. After that, just press the enter button, and the problem disappears.

Note that in the first and second cases, the command line should be started only with Administrator rights.

A few words at a time

The most interesting is that the message containing the error code 0x8007007b appears on all systems, but only in version 8.1 there is a button in the warning window, after clicking on it a window appears where you need to enter the correct value. But in general, both of the presented methods of Windows activation should not present problems for any user of any level of preparation.
