Pretty sure Microsoft isn't talking about using the rollback for this, but have some very decent file recovery software they remote in and run. Would be odd if they <i>didn't</i> have tools like that, although they're probably reserved for business clients under normal circumstances. Probably undelete.exe, the extra plus plus edition. For another $4.99 they'll automagically make more memory for your games too, with EMS, HIMEM(.sys) and memmaker(.exe). Because 640k actually <i>isn't</i> enough. Not for Pizza Tycoon anyway.
