Oh no, Google Earth has nothing to do with this. It's the fake Windows that's causing a problem. I don't blame anyone but whoever gave bek the disc for this one. Anyhoo, bek will need a legit copy of Windows, if he wants the updates to work. Sorry, bek. Anyways, if you have any earlier copies of Windows, you can just buy the upgrade version, and insert the earlier disc when it asks for a previous version. It doesn't have to install the older version - it just has to be a full disc.
If you don't have an earlier disc, it's OK - you just need to get the more expensive full disc. And in the meantime, I recommend backing up any files you need, because I would recommend a format right before you install the legit XP. Don't format now - but backup your necessary files. The reason I suggest a format is so that any traces of an illigitemate copy can be removed. If there's even a hint, Microsoft will reject you again and snub you if you call Tech Support. So let's get it cleared before the install.
Mandatory reminder: Formatting a drive destroys all files on the hard drive. No exeptions.
