Problem: Windows 8:

On February 29, 2012, Microsoft released Windows 8 Consumer Preview, the beta version of Windows 8, build 8250. Alongside other changes, the build removed the Start button from the taskbar for the first time since its debut on Windows 95; according to Windows manager Chaitanya Sareen, the Start button was removed to reflect their view that on Windows 8, the desktop was an "app" itself, and not the primary interface of the operating system. Windows president Steven Sinofsky said more than 100,000 changes had been made since the developer version went public. The day after its release, Windows 8 Consumer Preview had been downloaded over one million times. Like the Developer Preview, the Consumer Preview expired on January 15, 2013.

How many things were altered before developer version release?

With the Western nations unwilling to accede to Soviet demands, Stalin instead entered a secret Nazi–Soviet pact. On 24 August a 10-year non-aggression pact was signed with provisions that included: consultation, arbitration if either party disagreed, neutrality if either went to war against a third power, no membership of a group "which is directly or indirectly aimed at the other".

Context and question: Burke claimed that Bolingbroke's arguments against revealed religion could apply to all social and civil institutions as well. Lord Chesterfield and Bishop Warburton (and others) initially thought that the work was genuinely by Bolingbroke rather than a satire. All the reviews of the work were positive, with critics especially appreciative of Burke's quality of writing. Some reviewers failed to notice the ironic nature of the book, which led to Burke stating in the preface to the second edition (1757) that it was a satire.
What did Burke note in the preface of the first edition of the book?
Answer: unanswerable
