PC sales fell as consumers either put off new purchases in a tight economy or opted for tablet devices instead. Microsoft deferred a total of $1.36bn of revenue, which it will regain in the following quarter. This included $783m in licence fees for PCs pre-loaded with Windows 8, because it cannot recognise the revenue until the units go on sale on 26 October. It also deferred $384m for PCs that shipped with Windows 7 but are eligible for a $15 upgrade to Windows 8, and $189m for PCs that shipped with the new version of Office or are eligible for an upgrade. Microsoft shares fell 3% in extended trading.
