It wants 'real-world' data from testers; knows reverting to Vista will be 'a real pain'

Microsoft Corp. today asked people running the Windows 7 beta to return their machines to Vista before upgrading again to the impending release candidate of Windows 7.

The company will, in fact, block upgrades from the beta to the release candidate, and plans to require users who balk at the request to edit an installation file to successfully update Windows 7.

In a long entry on the company's Engineering Windows 7 blog, Microsoft asked users to revert to Vista before trying the release candidate since "upgrading from one pre-release build to another is not a scenario we want to focus on because it is not something real-world customers will experience."
