It’s best not to upgrade mid-project, unless your system really isn’t working. It’s just too big of a risk.
You might want to export to Quicktime in the meantime and use Microsoft’s free Windows Media Encoder to create your Windows Media files from the QT exports. Then do your upgrade once things get slower and you can take the time to troubleshoot should anything go awry.
