So just how much money was moved? Well, according to Information Week and the relevant SEC filings statements, about $259 million, or a boost of 6.5% in revenue to the division overall for a total of $4.24 billion rather than the $3.98 billion originally stated for Q1 2010. This also resulted in a 25% reduction in revenue for EDD, while the total -- $12.92 billion -- stayed exactly the same. Of course, all these bookkeeping maneuvers mean that Redmond's Windows division looked like it was making a decent amount more cash than it actually was, and when taking into account another complex move -- that of deferring $1.5 billion in upgrade revenues from Windows Vista machines sold in Q4 2009 to Windows 7 in Q1 2010 -- the resulting picture is a bit different than it would appear on the surface. Ultimately, it looks like Microsoft raked in an 11% increase in Windows revenue rather than the 66% reported, when removing both the bookkeeping changes from other units and the upgrade deferrals. Of course, this is all apparently technically on the up-and-up, in terms of financial reporting is concerned, but it does give some insight into the stunning profits recorded in the Windows division as of late.
