Microsoft has made available a Volume Activation Operations Guide that covers:
the utilities available to manage activation,
troubleshooting genuine software issues,
recovering from expired licenses and non-activated crippled systems,
resolving Windows Genuine Advantage issues that prevent you from installing some additional features,
managing each method of volume activation available.
The venerable Windows Deployment Services, the in-the-box deployment solution for client and server machines alike,
The Windows Automated Installation Kit, which includes the aforementioned User State Migration Tool and an image lifecycle management capability,
The Microsoft Deployment Toolkit, which makes creation of deployment images a snap, including preinstalled applications, and has special features to manage desktop configurations as well.
If youre installing more than five machines, its well worth your time to see how automation can help you do your migration faster and more consistently across all computers in your organization.
Dont just assume that your users will know what to do. Prepare to answer questions for weeks and months after the initial migration is offer, and consider having a quick-start guide prepared to ease users into their new Windows 7-based systems by showing them how to do several common tasks. These basic tasks include changing wallpaper, making the fonts larger, customizing their desktop, installing a printer, and accessing their saved documents either on their machine or on a remote file system.
Perhaps consider video training as well, as some users are better at seeing processes than reading about them.
