A friend brought me a new asus with windows 8 and she had no spyware or virus active and they ate up the files. Im getting popups saying asus files are missing.She didn't get a disk with it.Can I update it to windows 8.1 and still keep here key and fix the problem or what? Thank you.
there are many options my friend , you can run as admin sfc /scannow and see what you get, you can update to win 8.1 but you may end up with more problems. I suggest you fresh install win 8.1, and you can activate with existing win 8 key.
Before doing anything 'stupid', i recommend using Titos link and gather the key and check it to determine the installed Windows. In case Core/Pro is installed, no problems. For CoreSingleLanguage it would be problematic to get an ISO atm .
