She has the windows key?
If thats the case, reinstall Windows.
Step 1: Go to
Microsoft's page for upgrading to Windows 8 with a product key, then click on the light blue "Install Windows 8" button.
Step 2: Launch the setup file (Windows8-Setup.exe) and enter your Windows 8 product key when prompted. Continue the setup process until it begins downloading Windows 8.
Step 3: Close the Windows 8 setup window and confirm that you want to quit the setup.
Step 4: Back at the Microsoft upgrading to Windows 8 with a product key page, click on the light blue "Install Windows 8.1" button this time.
Step 5: Launch the setup file (WindowsSetupBox.exe), which will begin downloading the Windows 8.1 ISO.
Step 6: Once the ISO finishes downloading, the installer will take several minutes to check the download and uncompress the install files. When you're prompted to choose an installation option, pick "Install by creating media."
Step 7: Decide whether you want the installer to create USB flash drive media, or save the ISO file.
If you choose ISO, the ISO file (Windows.iso) will be saved to your PC and you'll be given the option to burn it to DVD. Once completed, you can actually go back and create the USB flash drive media as well. Just click on the "Install Windows" link on your Windows desktop. You'll be prompted to choose your installation option again. Pick "Install by creating media" again, insert a 4GB or larger USB flash drive, then choose the USB flash drive option. If you have any problems creating the USB flash media, you can still use the
Windows 7 USB/DVD download tool to create USB media with the Windows 8.1 ISO.
