I have a problem with my Windows Vista.

While I was working on some stuff with MS word an error message suddenly appeared saying this:

An unauthorized change was made for Windows

Windows Activation

Windows must be restored

An unauthorized change was made for Windows. You

must reinstall or restore Windows system files to

activate.

How do I reinstall Windows?

What is a system restore?

                                                            Close

When I close the message, it goes back to normal. After a few minutes of typing and editing, that same error message appears. Is there a way that I can get rid of that frustrating message box?

Hello Andrew,

Before troubleshooting the error, please check whether your version of Windows Vista is activated. Follow the below steps to do so:

  1. Click the Start button, and right click Computer and select Properties from the list.
  2. You will be able to view the system details and activation status System properties window.
  3. If Windows is already activated, “Windows is activated” message will be displayed under Windows Activation.

Occasionally, you may be prompted to reactivate the windows even if it is successfully activated before. This can happen when you re-install windows or make any major hardware changes on the computer. To avoid this, update your system with the latest windows updates.

Hope the information helps.

That error is related to activating the Microsoft Windows operating system. First, check that your operating system or Microsoft Windows Vista is already activated. If you verify that your operating system is already activated, there must be something wrong with your operating system’s protected system files. To check this, you can use the System File Checker utility or SFC.

Press the Windows key + R to bring up the “Run” dialog then type without quotes “cmd” then hit Enter. In the command prompt window, type without quotes “sfc /scannow” then hit Enter. When you are prompted to insert the Windows CD, insert your Windows setup CD or DVD on your optical drive then continue. Wait until the process completes.

When it is finished, close the command prompt then restart the computer. See if this works. If this doesn’t work, try restoring your system. Click “Start”, “All Programs”, “Accessories”, “System Tools” then “System Restore”. In “System Restore” window, make sure “Restore my computer to an earlier time” is selected then click “Next”. On the next screen, select an earlier date that has an available restore point.

Select a particular restore point on that date then click “Next” and then follow the instructions. When it is finished and your system is restored back to an earlier time, try checking then see if it works. If the problem continues, the last option is to format the system drive (C) and install a fresh copy of the Microsoft Windows Vista operating system.
